Concrete Perma-Lock™ Collar

ZERO MOVEMENT ENGINEERED POOL

A continuous bond of concrete is used around the pool to permanently lock together the wall structure with "A" frame or brace structure.

Seals pool structure against seepage of material underneath pool walls. The concrete Perma-lock™ collar eliminates wall shifting common with other types of pool construction. Allows pool to be emptied and serviced at any time.
