In part 2 we discuss pool coping, which is the cap, or cover, for the wall and provides aesthetics and safety along the pool’s edge. Visually, the coping frames the pool. Coping can be made of many different types of material, including cast-in-place concrete, brick, flagstone, precast concrete, travertine, aluminum or tile. The pool coping separates the pool structure from the pool deck, which means the deck can shift without adversely affecting the pool. For the purpose of this article we will primarily discuss the use of cantilevered Styrofoam forms for decorative cast-in-place concrete coping.
Pools are constructed with three basic types of materials — concrete (gunite), vinyl liners and fiberglass. Cantilevered Styrofoam forms are used in the construction of all three.
