Why do pools pop out of the ground?
7 min read
Asked by: Jessica Martin
Hydrostatic pressure, or water pushing upwards, is the reason why pools can pop up out of the ground. To alleviate this problem, the majority of concrete pools are built with a hydrostatic relief valve.
What causes pool pop up?
If a water line breaks or leaks under or near a pool the soil may become fully saturated over time. When the saturation reaches a point, that there is sufficient water under the pool, it may cause the pool to float or pop up.
What causes above ground pool collapse?
Pool Collapse – An above ground pool collapse is often caused by the results of ice damage, but it can also happen when there is too much snow accumulated on top of the pool and the frame cannot handle the weight.
Do above-ground pools pop?
Unfortunately, however, above-ground pools can collapse. Frames are usually constructed from corrugated sheet metal, and while it’s strong, sheet metal can’t always withstand the extra weight of several inches of melting snow and/or ice.
Will above ground pool collapse without water?
An empty pool (or as little as 1/4 filled) and an exposed liner on a hot day can cause the liner to shrink from the heat and deem the liner useless. An empty pool is also susceptible to collapse. Especially, in high winds and/or bad weather.
How do I stop my pool from popping out of the ground?
One of the best ways to prevent a popped pool is to make sure that you never leave your pool unfilled for too long. When a pool is empty, it now has hydrostatic pressure to counteract the surrounding groundwater’s stress. That makes it much easier for your pool to pop. An empty pool can cause some other issues as well.
How common is pool popping?
Thankfully, the pool pop up rarely happens. In fact, it’s an extremely rare occurrence, and it usually happens when there’s a major flooding event or hurricane in the area, which saturates the ground and creates a super high water table.
Can an above-ground pool collapse with too much water?
Above ground pools are more likely to collapse than inground pools, but both types of pools are capable of collapsing. Below are common causes of pool collapse: The weight of snow or ice on a pool’s cover.
Can you repair a collapsed pool?
You may typically use light pressure to bend the wall back into place if necessary; the pressure inside the pool may fix the wall automatically. Contact a professional pool repair service if the wall won’t go back to its original shape. Repeated or excessive force may damage the wall permanently.
Will a pool collapse with too much water?
You don’t need to drain your pool, as there is no risk to your pool by it being full. The only thing you lose with a pool filled to the rim is your skimmer’s surface cleaning action. Overall, it still draws water and the equipment is just fine.
How long can a swimming pool stay empty?
Modern concrete pools can usually stand being drained for as long as needed, but there’ll still be a risk of popping if the ground water level is high. Fibreglass pools are less resilient. The floor may come loose and float to the top when refilled, even after a short period.
Is it bad to leave a pool empty?
The Problem With An Empty Pool
When that amount of weight and pressure is removed from the structure, the pool can actually pop out of the ground due to ground pressure forcing it up. This can compromise its structural integrity, damaging the walls, floor, liners, and even the deck itself.
Can you leave an empty pool up all winter?
You may naturally assume it’s best to completely drain your pool of water for the winter months, because you fear the water will freeze and cause damage. Actually, it’s not good to leave your pool empty when the weather gets cold.
How much does it cost to fill a pool?
The average cost to fill in an inground pool is $4,000 to $16,000 for full demolition or $2,000 to $10,000 to fill in with dirt. An above ground pool removal costs $300 to $800, or $2,500 with a deck. The cost to get rid of a swimming pool depends on the size, depth, material, and accessibility.
Is it better to drain a pool or clean it?
Most in-ground pools will have to be drained and refilled at some point. But cleaning should not be the reason to do it. Pools will need to be drained and refilled every 5-7 years on average, or if there is a major necessary repair. Otherwise, avoid draining your pool if at all possible.
How often should I need to add water to my pool?
How often should I have to fill my pool? This will vary depending upon several factors including: weather, if the pool is covered or not, bather load, and if it is heated or not. With pools that are covered, a good rule of thumb is that they should not have to be refilled more often than once every 2 weeks.
Can pools overflow rain?
The pool will only overflow by the amount of rain in excess of the amount of rain needed to fill the pool to the top. So if your pool is the normal 3” below the top, the rain would need to exceed 3” before any additional rain would be available to overflow onto the deck.
Is it better to run a pool pump at night or day?

When should I drain my pool? Pool industry experts recommend you drain your pool and refill it every five to seven years.
How much water should a pool lose overnight?
Losing a half-inch or more overnight indicates a problem. A covered pool or spa tub will lose very little water from evaporation in a 24-hour period. Check the water level in your pool or spa tub before you cover it and turn off the pump system. You will know if the water level drops below normal.
How do you know if pool is leaking?

Is my pool leaking or evaporating?

Can a leaking pool cause a sinkhole?
A sinkhole can occur whether you have an inground pool or an above-ground pool. A pool that is allowed to leak into the foundation underneath can lead to a very large, very dangerous sinkhole. In fact, leaking water is the main cause of a sinkhole. Sinkholes start developing a long time before they actually appear.
