Fixing And Preventing Cracks In Poured-Concrete Swimming Pools

One of the realities of living in a home with a concrete swimming pool is dealing with occasional cracks and other common problems. Thankfully, when your pool's concrete develops cracks they can be patched and there are a few things that you can do to help ensure that your swimming pool will not crack in the future.

Here is some information on the formation of swimming pool cracks, how they are repaired, and how to prevent damage to your pool's concrete in the future:

Concrete Swimming Pool Crack Formation

One of the downsides of concrete is that it is always susceptible to cracking from the temperature changes that happen with the change of seasons. Pools located in areas with very cold winters often have more of a problem with developing cracks.

Another common cause of concrete pool cracks is unstable soil below the pool from when it was poured or from subsequent water intrusion between the soil and the concrete. The water forms channels under the concrete and it will form cracks over these channels as the weight of the water in the pool presses down on the concrete.

Concrete Swimming Pool Crack Repair Techniques

Cracks in your concrete swimming pool should be repaired as soon as they form to make the repairs easier, cheaper, and more likely to not crack again in the same place in the future.

To repair a crack, you need to drain the pool's water down below the cracked area and chip out a small amount of the concrete that surrounds the crack. Using a cotton rag, wipe the cracked area with acetone to remove any oils on the concrete that may prevent adherence of the patching material.

Apply a swimming pool patching compound to the area, following the directions on the package that it came in. Allow the patching material to dry before you fill the pool back up with water.

Concrete Swimming Pool Crack Prevention

Finally, there are some simple things that you can do to help prevent cracks and other damage from occurring inside of your poured-concrete swimming pool, such as:

  • keep water in the pool year-round to prevent lifting by groundwater
  • repair all small cracks as soon as they appear to prevent them from growing into larger problems
  • replace broken or damaged tiles to prevent water from seeping behind the pool's concrete

These three things will help prevent future cracks and preserve the structural integrity of your home's poured-concrete swimming pool. For more repair tips, contact a company like Splash Swimming Pools.
