Protect the base of your above ground pool or spa with the Bestway Pool Floor Protector. Featuring 9 pieces of floor protector, covering 2.25 sq. m (24.2 sq. ft.) of ground, the durable material is designed as an initial layer to spread out beneath your pool or spa as a buffer from potential damage caused by twigs, rocks and other ground debris. Simply level the ground where you plan to assemble your above ground pool or spa, place the interlocking pieces of the pool floor protector over your chosen spot, and start building! The pool floor protector will reduce the wear and tear on the bottom of your above ground pool liner, protect your lawn and provide additional stability to your pool or spa. If you need more coverage, you may need additional packs to expand the area. You can also interlock the squares together to create a decorative and protective pathway!.
