Swimming pools are great additions to any property. However, the installation process must be done correctly to ensure the longevity and stability of the pool. One problem that commonly arises is soil settlement around the pool area. In this blog post, we will discuss why soil settles around swimming pools and what can be done to prevent it.

Improper Compaction

When constructing a house, proper compaction of soil is necessary to prevent settling issues in the future. The same principle applies to swimming pools. Unfortunately, some pool installers neglect this important step. They dig a big hole, build the pool, and mound up all the loose soil around the shell before adding a deck on top. If the soil is not properly compacted, settling will eventually occur.

Pool Leaks

Another cause of soil settlement around swimming pools is leaking pipes. Continuous water seepage can cause soil to erode. In some cases, water leaks can lead to sinkholes. Therefore, it is crucial to address water leaks promptly. Our technicians are thoroughly trained in Alchatek’s Deep Lock® process, a highly effective way to stabilize the affected soil.

Insufficient Footings

When constructing a pool deck, it is essential to have proper footings to support the load. However, we have found that many pools do not have footers at all, and the load is sitting on just a 4-inch-thick slab, causing settlement issues. Additionally, if the yard pitches downward behind the pool, a deeper footing is necessary to prevent stem wall rotation.

Improper Drainage

If the pool is installed at a lower elevation than the surrounding land, proper drainage must be implemented. When water builds up around the pool, it can undermine the foundation and cause settling issues.

Pavers Settling

When pavers around the pool deck begin to settle, it is likely due to one of the soil issues mentioned above. Depending on whether the pavers have a concrete or crushed concrete base, different stabilization methods may be necessary. Our team will diagnose the issue and provide the best solution, whether it be through the Deep Lock® process or standard slab lifting.

Prevention and Repair

Soil settlement around swimming pools is a common issue that can be prevented. Proper compaction, addressing water leaks promptly, installing proper footings, ensuring proper drainage, and utilizing effective stabilization methods are all essential steps in preventing soil settlement. If you’re looking for a soil stabilization or concrete leveling contractor near Tampa / St. Petersburg, Florida – click here to contact us today for a free inspection!
