Product details

Armor Shield is GLI's floor pad for above ground pools, and this is the 21' round size. It goes down between the prepared base and the vinyl liner.

What it is made of

Armor Shield is a polypropylene geotextile blend rather than the foam padding that has traditionally been used for this job. The point of the material is puncture resistance: it minimizes the cuts and punctures that come from rocks, roots, grass and even glass working their way up through a sand or soil base.

The other two jobs

A pad also slows convective heat loss into the ground, so the pool holds its warmth better than it would on bare earth. And it puts a softer layer underfoot, which is the difference most bathers actually notice.

Installing

The pad is laid over the base after it has been leveled and cleared, and before the liner goes in. Getting the base right first still matters, since a pad protects the liner but does not flatten a bad floor.
