THE RISKS ASSOCIATED WITH EXPANSIVE SOILS!
When deciding to build an inground pool, it is crucial to prevent soil movement which puts the pool and decking at risk of being damaged and causing costly future repairs.
Problems to the pool can include:
- Causing the pool to come out of level, which in return will cause an uneven water level in the pool.
- Cracking, which can cause water loss.
- Broken plumbing, heaving, and skimmers to not work properly.
Problems to the decking can include:
- Deck heaving, which can crack the decking.
- If pavers are used instead of concrete, expansive soils can lead to constant paving repairs.
- If deck heaves and the pool stays stationary, the deck will heave higher than the pool, causing the mastic seal to break and water to get down underneath the pool into the expansive soil which will cause even more problems.
SWIMSOIL has provided a video on how to properly use the USDA Web Soil Survey as a reliable tool to help builders and homeowners understand when SWIMSOIL is needed for soil treatment.
