GacoPedestrianDeck systems are seamless protective membranes that incorporate organic granules for added slip resistance. The materials expand and contract with normal temperature shifts to provide long-lasting leakage protection. The fully integrated GacoFlex coatings are specially formulated to bond together and avoid shrinking, cracking, chipping, peeling, lifting or buckling when the temperature changes – creating a deck surface which will retain its strength and beauty season after season.
