Frequently Asked Questions

Can I put a pool liner directly on concrete?

Yes, you can, but it is never recommended to place the vinyl directly on the concrete. You must use a protective barrier like a pool pad or wall foam to prevent the abrasive concrete from tearing the liner through friction.

What is the best padding for a pool on a concrete patio?

A 1/8-inch or 1/4-inch closed-cell foam is ideal for the walls, while a high-density geotextile pad is best for the floor. These materials are designed to resist mold and provide the necessary cushion to prevent friction tears.

Do I need sand under a pool liner on concrete?

While sand is common for dirt-base installs, it is not recommended for concrete. Sand can shift or wash away on hard surfaces, leaving the liner vulnerable. Foam coves and pads are the professional standard for concrete bases.
