WATERPROOF WALKway & balcony coatings
Durable waterproof coatings for exterior walkways, balconies, courtyards and entries.
WATERPROOF WALKING DECKS
Exterior walking decks and corridors take a daily beating from foot traffic and, in Southern California, decades of sun exposure and rain. When the waterproofing membrane underneath fails, water finds its way into the structure below — and into the units or rooms underneath. We install fully bonded waterproof deck systems engineered for high foot traffic and harsh exposure, with a slip-resistant finish in the color and pattern you choose.
Best for: Apartments, HOA’s, single-family homes, and commercial properties with elevated walkways, courtyards, balconies, patios and entry decks.
