Water Your Yard to Prevent Damage to Your Pool

We had a very wet first six months of 2024—our 30-year average is 36.14” of rain per year, and we are at 28.74” so far this year*. With that being said, we have received no rain in the past month—the last rain was on June 5^th. Although there is now rain in the forecast, we have entered a time of year that is typically very hot and very dry. This can impact pools in the north Texas area, and we all need to be aware of it.

This area tends to have pockets of fairly expansive soil—soil that contracts when is gets dry and expands when it gets wet. Therefore, extremely dry, hot periods can really dry out the soil—causing it to contract. When it finally does rain, expansion of the soil will take place. Whatever is in contact with the soil during this time of contraction and expansion also experiences movement. This movement can damage not only pool decks, but also roads, house foundations, driveways, sidewalks, and patios.

Although pool builders working in this area use cushion sand and steel rebar in the construction of their pool decks, these pool decks still require your attention to help prevent raising, settling, and cracking. In addition, this movement can also damage the expansion joint (either called the mastic joint or the deck-o-seal joint) between the deck and the pool, which needs to be checked periodically.

Pool decks are not warranted against this raising, settling, and cracking. Depending on the moisture content of the soil, this raising or settling can be up to an inch or two. Although it is next to impossible to completely avoid some movement in your pool deck, consistent soil moisture content is the key. Avoiding extremely wet or extremely dry soil conditions can help prevent movement. Following are some tips to help you avoid problems:

How to avoid having soil that is too dry

• During extremely dry times, be sure to water your yard enough to avoid the separation between the soil and the pool deck. This separation can cause movement.

How to avoid having soil that is too wet

• Do not allow drainage to fall towards the pool deck.
• Pay close attention to sprinkler heads that are up against the pool deck; they can erode the cushion sand under the deck, causing the deck to move.

Remember that consistency is the key – try to avoid soil that is too dry or too wet.

We hope that you enjoy the rest of the summer and that your pool is getting plenty of use!
