Preventing Root Damage in Inground Fiberglass Pools

An inground fiberglass pool.

One of the biggest advantages of inground fiberglass pools is the fact that fiberglass resists tree root invasion and damage. It also flexes and moves with the earth making it a very good choice for people in earthquake prone regions. Fiberglass pools come in a variety of sizes and shapes and can be installed within days rather than weeks. Inground fiberglass pools also resist grounds heave, which is what happens when the dirt around freezes and thaws. It's no wonder that people all over the country are finding inground fiberglass pools the perfect choice for adding a swimming pool to their home.

Placement of Your Swimming Pool

Swimming pool placement is an important choice. You want the swimming pool to be close to your home and easily accessible. Other considerations are the space available, landscaping, grading, set backs, fencing, and accessibility for plumbing and maintenance. Once you have decided where to put your inground swimming pool, a reputable pool installation company will provide a schematic for plumbing, drainage, and machinery access. Consider the placement of large trees and their roots when digging the hole for your pool. Remember that large trees have roots that spread at least as far out as the farthest branch. Digging a hole for your pool too close to a large tree could damage the root system and compromise the longevity of your tree.

Tree Roots and Leaves

Ingrown fiberglass pools resist root damage better than vinyl, concrete, or plastic pools. Even stubborn roots do not penetrate the fiberglass mesh. Tree roots can literally move concrete, but tend to grow around fiberglass. It's still important to consider tree placement when installing any landscaping around your pool or installing a pool with existing large trees. Tree leaves can leave stains in your pool. Another advantage of fiberglass is its ability to be cleaned without harsh chemicals and abrasives. The dark brown tannins can be cleaned with TSP. Regularly use a leaf skimmer to prevent leaves from settling on the bottom of the pool, staining the surface and clogging up the drains.

Temperature Changes and the Frost Line

One issue to always consider with any pool is the frost line. Inground fiberglass pools have an advantage during freezing weather, because they can flex and bend with the changing temperatures. Fiberglass pools are backfilled with sand and gravel, which allows for maximum movement during cold weather and earthquakes. Having an adequate water drainage system around your inground swimming pool is critical because most damage is actually caused by freezing water that is trapped next to your pool rather than the backfill or dirt. Your pool contractor should know the frost line in your area and bury any water pipes or electrical lines according to local codes.

Keep Your Inground Fiberglass Pool Full

Inground fiberglass swimming pools are designed to always have water in them. Ironically, this actually helps them maintain their shape and prevents cracking. Fiberglass pools can literally pop out of the ground when empty if enough water or ground pressure builds up around them. Just like a boat floating on the water, your pool will float on the water around it. If you ever need to drain your pool, please consult a professional to make sure you don't inadvertently cause any damage.
