Summer is fast approaching. If you have a pool on your property (or if you manage a public pool), it won’t be long until people are walking all over your pool deck.
There are a couple very common causes for the soil washout that creates the environment for a sinking pool deck slab:
- Cracks in the pool structure leaking water into and soil and washing it out.
- Loose back-fill on sloping properties.
The first cause is pretty self explanatory. The second cause may need a little elaboration. Basically, if a pool is built on sloping property, the construction team will back-fill soil onto the side of the pool that needs it. If this soil is not compacted properly, it can start to washout over time.
Regardless of the cause, soil washout removes support from the pool deck slab and creates the condition for sinking.
As we explained in this two-part blog series…
…tripping hazards can be extremely costly, both from a legal perspective and more importantly from the perspective of basic human safety.
After your soil is repaired, you will want to get any cracks sealed that may be leaking water into soil and washing it out in order to prevent future trip hazards.
