A specialized caulking, called Mastic, is installed in the expansion joints between the coping and decking of the pool and in any gaps found around
masonry. When Pools, Patios and Walkways are built they must have expansion joints. These gaps are necessary to allow for settling and insure
your pool deck has room to move without causing damage to the pool coping. One of the most important expansion joints exists between the
swimming pool coping and the decking around the pool.

Expansion joints are sealed with a semi self-leveling material designed for
this masonry application. This engineered polyurethane material is the
highest quality and will insure a lasting seal. We offer the caulking in
several colors to compliment the existing coping, decking and masonry.
