Causes Of Pool Wall Damage

There are many reasons contributing to the pool wall being cracked or collapsing. The first major factor might be that the soil underneath features expansive properties and when it absorbs moisture, it swells. As a result, the bloated soil forces the footplates and handrails upward, collapsing the pool wall. Furthermore, soil tends to expand comparatively more in cold temperatures and during heavy rains as well. On the other hand, dry soil contracts causing the ground beneath the pool to shift. If you have filled your pool with water till the top when the temperatures are frigid, the water inside an attached skimmer might freeze as well. Even if the water level manages to drop, the ice attached to the skimmer pulls the wall down as well.


If the problem with your pool and the ground underneath is related to the expansion or contraction of the soil. It will fix itself and the wall will straighten up. However, if the pool has a lot of expansive soil underneath that contracts due to moisture, then it is going to need a brace underneath or removal of the soil is the only solution. Furthermore, removing the dirt around the handrails and footplates is going to pop the wall back into place as well. Additionally, watering around the pool during dry seasons is also going to prevent soil contraction.

On the other hand, if the wall has collapsed due to a frozen skimmer, the changes in pool pressure during a thaw should fix it. Moreover, light pressure from the inside of the wall maybe required to straighten it manually. If you observe that the will did not go back into place, you will have to reduce the water up to 6 inches and then push the wall back into shape from the inside. And since you will not be using the pool during the winter season, cover the skimmer, which will prevent water from getting into it.
