Ice Damage to an Aboveground Pool

uh-oh-better-get-maaco-2This winter has been tough. Record cold temperatures and snowfall.

Aboveground pools are hit the hardest. The pressure of several feet of snow on top of a 20,000 pound floating iceberg can rip liners or crumple walls.

Today, we’ll look at the worst winter worries for aboveground pools – Ice and Snow.

Iceberg in your Pool

Aboveground pool walls are cold, like an ice tray, and the ice sheet grows very fast and thick. Inground pools have soil surrounding the walls, which gives both support and temperature regulation.

The water level in your pool, supports the floating sheet of ice, as it presses up against your pool walls and liner. If the pool develops a leak, or if the water level is accidentally lowered – the heavy ice sheet can scrape down the sides of the pool wall as it falls, shredding a pool liner. If the water has frozen into the skimmer opening, it can damage the wall, as shown below.

Especially when the walls are rusted from skimmer and return leaks, as shown here.

Snow Damage to Aboveground Pools

A foot of snow on top of a 24′ round pool weighs nearly 7000 pounds. Triple that to 3 feet of snow, and many pool walls just can’t stand the pressure. Walls typically buckle at the weakest point; the area of the wall that the skimmer and return are connected into.

Now we have real problems, because when the water leaks out, it no longer supports the ice sheet above it. If it falls suddenly, it can rip the liner or damage the pool wall.

Ice & Snow Repairs to Aboveground Pools

Wall damage may seem unrepairable, and in some cases it is – but in other cases, there are methods for repairing an aboveground pool damaged by snow and ice.

steel-pool-wallSince most aboveground pool walls come in a continuous roll of sheet metal, you can’t usually just order a new panel, unless the damaged area is a separate stainless steel panel used for the skimmer and return.

But, you can usually straighten out bent and buckled steel walls and uprights. All you need is a 2×4 and a large hammer or maul. Lower the water in the pool to a point below the damage, and pull the liner away from the wall. Have a helper hold the 2×4 on the inside of the pool, while you hammer on the outside, flattening the wall, removing the creases, and restoring the wall to full height.

Preventing Ice & Snow Damage

  1. Always use an Air Pillow under winter pool covers.
  2. If the pool leaks during winter, release the pool cover.
  3. Remove snow buildup on top of the pool – carefully.
  4. Use skimmer closures like Aquador, to protect your skimmer.
  5. Use a good pool cover pump to keep the ice sheet thin.
