Gladon's Original Pool Cove

Flexible
Lightweight
Easy To Clean
Extends Pool Life
Installs In Minutes
Can Not Be Washed Out
Helps Prevent Corrosion
Over 30 Years Of Proven Performance
Eliminates Liner Failures Due To Cove Washout

All above ground pools need a cove.Read any pool manufacture's installation instructions and you will find: "The cove is a vital structural element of your pool."  A cove is needed to keep the weight of the water in the pool liner from causing it to balloon out under the bottom of the pool wall. Previously, pool cove had to be hand built, in place, using tons of sand or dirt. Liner failures due to cove washout were all too common. Corrosion occurred rapidly where metal components, at the bottom of the pool, came in contact with moisture in the sand or dirt. Hand formed coves are uneven making cleaning difficult.

Gladon invented preformed Pool Cove. Over 35 years ago, Gladon Company had a better idea ! We invented and patented our original preformed pool cove. Our coves have been proven in millions of pool installation. We have more than 35 years experience manufacturing pool coves.

Gladon Original Cove is a 4 inch tall by 3 inch across the base preformed cove made from chemically neutral closed Ethafoam, and is safe for use with all pool liners. Lightweight and easy to handle, Gladon Original Cove comes in 48 inch long sections that bend easily without breaking and are compatible with all pool brands. Its unique plastic backing strip makes it easy to install in most makes of pools. The plastic backing strip locks each section of cove into the bottom rail, allowing it to move as the pool wall expands and contracts. Unlike sand or dirt, Gladon Original Cove can not be washed out and will not hold moisture against metal components. This feature reduces corrosion and may add years of life to a pool and its components. Because Gladon Original Cove is made from a high density foam, it will not change shape or indent, making pool cleaning easier. Available in floor display cartons or kits, with just the right number of pieces for a particular size pool. Do-it-yourself customers and pool installers will save hours of back breaking work using our preformed cove. Installation crews can increase productivity and eliminate call backs simply by using Gladon Pool Cove.

WARNING !Not All Pool Cove is the Same

All other brands of pool cove are inferior and do NOT have the density and other properties needed to perform properly under the weight of all the water in a swimming pool. Poor quality pool cove can compress and collapse. This can lead to catastrophic liner failures and other problems. Cheap imitation cove has even been shipped with a warning label right on the box that looked like this ...

Always insist on genuine Gladon Brand Pool Cove Always Insist on Gladon Brand Pool CoveNO Failures With Gladon Pool CoveGladon Cove With InkJet Markings
Each piece of Gladon Brand Pool Cove has Gladon.com printed on it. Look for Gladon.com on your pool cove...this is your assurance it will perform properly and is not a cheap imitation or knock-off.

pool liner coving away from walls and floor

I was recently contacted by a pool owner who had a new liner installed. They are unhappy with how the liner fits in the pool and contacted me to learn more about how a liner is supposed to fit in a pool - specifically the area where the shallow end walls meet the shallow end floor. What can happen, and did happen in the case of this customer, is that there was a noticeable cove in the liner in this specific area. Which is to say that the pool liner does not follow the 90 degree contour from the floor to the wall, but instead transitions with a slope. So is this normal? Is this a problem? Did the liner installer make a mistake, or perhaps was the liner not manufactured properly? The answer, as usual, is maybe.


Nothing is ever cut and dry in the pool industry. It was very clear that this customer wanted me to tell them that this is no good, and you can not have coving in a vinyl pool, and that the original installer should come out with a new liner a make it perfect. Unfortunately I did not agree. The customer was most concerned because the liner did not have a sharp 90 degree profile in these corners...and they almost never do. So why would a liner not fit perfectly tight into these corners? There are a few reasons to consider:


Cold weather installation - Installing a liner is a warm weather operation. Sure, you might be able to throw a liner in during cold weather, but I would not let someone do that to my pool. Liners need the heat from the sun to become supple, and so that they will stretch evenly throughout the pool when you apply the vacuum. The difference between cold vinyl and warm vinyl is literally night and day when it comes to how hard (or easy) it is to fit the liner in the best possible location. A liner that fits a pool nicely, but that is installed on a cold day, will ultimately fit the pool poorly. Yes, it is possible that the liner could still fit nicely on a cold day, however the vast majority of liners need to be stretched and manipulated to achieve the best possible fit. On a cold day your ability to stretch and manipulate the liner is near zero. If the liner was cold, then the cove in the pool would be much more pronounced than the same liner left to bake in the mid day summer sun for 10 minutes. When you turn on the vacuums to pull the liner into place a cold liner will not stretch under the strength from a liner vac, but a hot liner will suck back to the wall so tightly that it will look like it is painted on.





Varying shallow end wall depth - When you measure the height of the shallow end wall, you measure in multiple places and then the liner is made to fit the shortest wall height. In a perfectly built pool these numbers should all be the same, however in the average backyard pool the floor will not be perfectly flat and will have as much as a few inches of height difference between different areas. The reason why the liner is made to the shortest wall height is simply that if it was made longer to suit the longer areas, the shortest area of wall would have too much liner material and you would have a wrinkle in the liner at this location. Wrinkles in a pool liner are unacceptable and this is why liners are made small and stretched into place. It is important to understand that a very small amount of stretch for a liner is no problem at all, and with heat and sun the liner will pretty much stretch just under the weight of gravity itself. A small amount of stretch, especially where the cove of the liner is (where the wall meets the floor) is normal, however if the liner was simply measured (or made) too small then it can become too tight in this area. This is why it is not exactly cut and dry with coving. The liner might need to be slightly undersized in some places, but ultimately, some areas with coving are better than ending up with wrinkles because there is just too much liner in some places.


Orientation of the liner - If you simply hung the liner from the coping track and turned on the vacuums it is very likely that you would have too much coving all around the shallow end of the pool. Often, the deep end of the pool will steal material from the shallow end and this results in extra coving problems. Fitting the liner to the best orientation can reduce some of the coving in the shallow end and most of the time this attention to detail when installing the shallow end is enough to get rid of (enough) coving for a quality installation. This is accomplished by putting the shallow end where it needs to be, and then weighing down the liner with salt bags (or a few helpers standing on the liner at key locations) to keep it in place while you turn on the vacuums. Once the air has been removed from behind the liner, it will be much less inclined to shift, and you will find that the shallow end is able to resist the deep end from pulling it away from the walls. If a shallow end had too much coving, in many cases simply turning off the vacuums, resetting the liner closer to the shallow end walls, and the turning on the vacuums again will resolve the problem. The deep end of the pool has so much vinyl in it that it will have no problem getting enough stretch from all directions to stretch into place. The shallow end, by comparison, has much less vinyl to work with so you need to put the shallow end right where you need it to be in order to get the best fitting liner and least coving at the foot of the walls.


How Much Cove Is Acceptable In A Pool Liner?

pool liner coving
Not all liners, most in fact, will have some coving in the shallow end. Thinner 20 mil liners will be much more inclined to follow the exact contours of the pool walls and floor, and the thicker 27 mil and 30 mil liners will be more inclined to cove (especially if installed cold and without sun). It is normal to have some coving where the wall meets the floor, but how much is too much?


Certainly if there is too much coving this can put undue stress on the liner seams, and can also allow the liner to take damage from sharp objects (and vacuum cleaners) easier than a liner that has less coving. When you have way too much coving what will happen is that the cove becomes a tripping hazard and when you approach the edge of the pool your foot slides off the cove and you fall forwards. This is extremely dangerous and totally unacceptable, however a few inches of coving will not cause this problem.


The profile of the cove in your shallow end should not exceed about 2" and, in theory, is optimal at zero coving altogether. Which is to say that if your liner sits more than two inches off the floor and wall this would be considered fine, or "good enough" by most real world liner installers. Even three inches might be acceptable depending on the difficulty of the installation as well as how detail oriented the installer is. However, if you have eight inches or a foot of coving where your floor meets your wall then this is not acceptable and needs to either be reset with a better fit, or reinstalled with a new, better fitting liner.



There are a lot of variables involved with this question of floor and wall coving and just how much cove is considered acceptable. In theory, zero coving is the best and this means that the liner sits tights against the floor and walls with zero free space underneath. This is certainly possible to accomplish with careful measuring and manufacturing, and by installing the liner during ideal weather conditions. If you tried to have a liner made exactly to fit all coves in a pool without any stretch at all, the chances to have a wrinkle somewhere would be very high. Much higher than if the liner is made just a little bit small and allowed to stretch into place.


When it comes time to install, if you only need to install one liner then I suppose you can pick the best day to get it done. If you install liners all day, every day, you will experience all kinds of weather conditions so in the real world some pool liners get installed when it is cold, or overcast, or raining, all of which can compromise the quality of a liner installation. Also the pool is often in less than ideal condition as well. Some pools are built poorly, and some pools are really old, some are both. So what are ideal conditions?


Ideal liner installation conditions: First, the liner would need to be installed on a hot and sunny day to ensure equal and even stretch in the liner. Next, the pool floor would need to be flat to within 1/4" inch (most are not) or else the liner will need to be too short in some areas to avoid being too long in any areas on the wall. Too much liner anywhere equals a wrinkle so the goal is to fit the liner as best as possible, without being too large in any one place. Finally the liner needs to be oriented correctly. As a person who has installed pool liners their entire adult life I can tell you that in a lot of cases the liner can fit better, but this will involve turning off the vacuums and manually adjusting the liner. This might also include redoing some tape around the vacuums and in total could take an hour or more to reset and then try to vacuum into place again on some difficult pools.


In many cases where there is excessive coving, the installer might have been able to improve the situation if they spent the extra time and effort to do so. It is easy to take a "good enough" approach when you do the same job day in and day out, but it is important to try to see things from the perspective of the customer...they are going to have to live with this liner every day and if there is something that you can do to improve the fit of the liner, extra effort should be taken to provide the highest quality liner installation possible. This also might include waiting until a better day for more heat and sun to install the liner. This can be a bitter pill to swallow if you are a busy liner installation technician, however these are the chances you take when you attempt to install liners in marginal weather. If you end up with a tight fitting liner, no overhead sun, and a picky customer, then you might find yourself installing the liner twice. Better off to just wait for the right day to do the job the first time in my opinion. At 100 degrees Fahrenheit, with overhead sun, a vinyl liner practically has the consistency of soup and you should have no problem eliminating all coving from the pool completely - but if the pool needs a liner now, and colder weather is coming, then some coving of your liner might be the lesser of two evils at this point.

With Pool Cove
Liner rests tight against cove creating a sealed barrier, keeping moisture from getting between the wall and liner.

    

With Pool Cove
Sand and dirt can be washed out leaving a gap and causing excessive strain on the liner that could result in liner failure.

A Pool cove becomes part of your pool to seal the space between the wall and the liner and to prevent liner strain. Made from chemically-neutral foam, it helps fight corrosion. It's compatible with all vinyl liners. Eliminates the need for banking of sand, otherwise used to create a sealed barrier between the wall and liner. Accommodates wall stretch to help prevent liner tearing and leaking. Fights corrosion to add years to a pool's life expectancy. Will not erode or freeze; holds its shape indefinitely.

What is a Pool Cove?

Lori Kilchermann

Lori Kilchermann

Pool cove, or coving as it more commonly called, can be found on above-ground swimming pools all around the world. An above-ground swimming pool is constructed with a very thin and flexible outer wall which contains the liner and the water. The outer wall is supported by the pool cove, which is typically thin aluminum channel which runs from the ground to the top of the swimming pool as well as around the top edge of the pool wall. Made from a slightly wider pool cove, the top edge not only creates structure that will prevent the pool wall from collapsing or bulging out, but it also provides a more comfortable edge on which to enter and exit the swimming pool.

When installing an above-ground swimming pool, the outer wall is set into place while the pool cove is installed. Once the pool cove is in place, the pool wall can be stood into position, placed against the cove and locked in place by installing the top rail or edge. The pool cove acts much like a skeleton, giving the pool wall much-needed support and strength. Without the pool cove, the swimming pool would have no structural strength and would likely collapse when filled with water.

The actual swimming pool wall is not much thicker than the swimming pool liner. If not for the pool cove surrounding the top edge of the swimming pool, it would be unpleasant to rest by leaning over the top edge of the pool. The cove is also used as a safety device. Another very critical function of the coving is to secure the liner inside of the pool wall. The liner is sandwiched between the pool wall and the vertical coving channels and locked in place by the coving that encircles the top edge of the swimming pool wall.

Skeletal strength, comfort, liner integrity and security are all functions of the pool coving. The above-ground swimming pool relies on the coving for much more than aesthetics. The aluminum channels stand guard around the outer perimeter of the swimming pool, providing support to the liner and the pool walls. While the coving protects the wall from bulging when filled with water, it cannot protect the wall from bulging due to ice. In cold climates, it is recommended that the swimming pool be drained of half of its water, thereby protecting the pool from expanding ice which would damage the pool.

When installing an above ground swimming pool, there has to be a transition between the bottom of the inside of the pool wall and the floor of the pool. You can’t just have a sharp angle where the two meet, so an embankment or coving has to be applied. This is called pool cove or coving.

WHY IS A POOL COVE NEEDED?

As a pool installer for more than three decades and a fairly smart guy, I only know of two reasons coving is needed for the proper installation of an above-ground swimming pool. There may be some nerdy or engineering reason or explanation for coving, but that won’t be covered or considered here. If you want that, I’m sure there are a few “internet pros” out there with pillow-soft hands and rosy cheeks that can explain it to you.

Pool cove helps distribute outward and downward pressure from water weight

An above ground swimming pool is usually at ground level. This means that the water from the pool is held in only by the wall of the pool and not the surrounding earth (like it would be supported if it was in the ground some).

Now, water is heavy. A gallon of water weighs 8.34 pounds (3.78 kilograms for those not in the US). The overall weight of an above ground pool can really be heavy. A 24’ round pool (which is the most common size) holds about 14,000 gallons. Times 14k by 8.34 and you get more than 115,000 pounds. This is a lot of weight. For all you rednecks out there, that’s about the weight of 25 Ford F-150s.

Above ground pools are a big cylinder of water that has a lot of outward and downward pressure. The outward pressure (pushing out from the pool’s wall) increases at you get to the bottom of the pool. This means that the greatest outward pressure is at the very bottom of the wall.

To help alleviate all that outward pressure at the bottom of the wall, a coving or embankment is placed all around the pool’s bottom going up the wall. This relieves some of that pressure by transitioning it from the bottom of the wall to the pool’s floor. Are you still with me, or did I lose you?

An above ground pool doesn’t absolutely need a coving. I only say that because I’ve seen a few (maybe 3 in thirty years) above grounds without one and were up for several years. I wouldn’t have believed it if I didn’t see it for myself. Personally, I wouldn’t get near an AG pool without coving.

Pool cove protects the liner from the bottom track

This isn’t as big and badass a reason as number one, but it’s valid.

Bottom tracks and connectors on above ground pools can have sharp edges that do not sit perfectly in place. Because of this, you don’t want the liner touching or near those parts. The above ground pool cove covers the bottom track well which protects the liner from getting rips or holes in it.

OPTIONS FOR ABOVE GROUND POOL COVING

Making a cove for an above ground pool installation is pretty straightforward, so you don’t have many choices. There really are only two.

With most of the installs I have done over the years, I have used the earth to make a cove with. This is just a manner of taking some of the dirt from the pool’s earth bottom and making an embankment upward and along the bottom of the pool wall. If the earth is too hard, then send is brought in to be used to make the cove (as well as leveling the pool bottom).

The only real question when using sand or earth for coving is how big should I make the above ground pool cove? Way back in the 1980s and early 90s, I used to make a rather big cove for pools. Maybe going six to eight inches up the pool wall. Lately though (meaning in the last twenty years), I usually make my coving about four to six inches up the wall and out from the wall.

I have learned that in most cases, a bigger cove is not necessary. If you are DIYing it though, it’s better to make the coving bigger than smaller. A bigger cove is better just in case you screw something else up with the install.

I recommend wetting down and tamping your earth or sand cove. You want to make sure the cove is nicely packed in.

The other option you have for coving is a thing called foam coving.

WHAT IS FOAM COVING?

Although the product available called “pool foam coving” has been around for more than twenty years, I am old enough to remember when it didn’t exist.

Many years ago, when they used to deliver milk, above ground pool installers could only use sand or earth for their coving. Then, to solve the problem of installing pools on concrete in retail showrooms, the foam cove was invented.

Using sand for coving for pools on indoor display didn’t work too well. The sand might escape some and make a bit of a mess in showrooms. So, someone non-famous came up with the idea of getting long strips of foam triangles maybe 6” by 6” and use that for the display pools. They wouldn’t come apart and make a mess and look nice and uniform when customers looked in at the full pool. And so, the pool foam cove came to be.

For some years, the foam cove was only used on pools that were installed on concrete. Eventually, retailers started selling it with pools that went on the earth as well. At first, I thought it was stupid. I had been an installer for years and the earth cove was fine. Why add an unnecessary product? I mean, it was a great idea for concrete bottom pools, but a waste of money for a pool on the ground.

Some years went by and the foam cove gained some popularity, and I eventually accepted the idea. Now, I would say that about twenty percent of the pools that I install have a foam coving.

SHOULD I BUY FOAM COVING FOR MY ABOVE GROUND POOL?

As a trusted pool installer, I get asked all the time whether or not they should buy foam cove for their above ground pool. My answer from years ago was a hard “no” as I didn’t like the idea of adding a product that was unnecessary.

Lately though (meaning in the last ten years or so), my opinion is to get the foam cove only if it’s in your above ground pool purchase budget to do so. For what it really is, it’s pretty expensive. Expect to pay around $100 for a common size above ground (24’ round) for some long triangles of foam pieces. It may not seem like a lot of money when making a two to four thousand dollar purchase. But you will be adding something you don’t need, so that’s a thing.

If you are planning on installing the pool yourself, I guess I would recommend getting foam coving. It’s almost impossible to install wrong and will guarantee that the pool will have a sufficient coving, which I think is important.

PROS AND CONS TO GETTING POOL FOAM COVING

PROS

1 Makes for a more uniform, smoother cove which looks and feels better
2 Decreases the margin for error with DIYers
3 Won’t wash away if there is a leak near or at the pool wall

CONS

1 Adds to the cost of the pool
2 May have to be replaced when replacing the liner (but usually not)
