The failed sealant in the crack-chasing and in horizontal joints in this picture are commonplace in parking deck structures throughout the world. It is widely recognized that when it comes to leaks, cracks and joints are the main culprit. This parking deck had an existing deck coating on it, but all the crack-chasing and horizontal sealant failed in a matter of months. The question becomes how to repair the deck so that no cracking would come through the deck again.
The sealant fails under the coating and leaks. In these pictures, we see where a standard urethane deck coating system was used to waterproof a deck. The urethane deck coating system and crack-chasing alone, totally failed to waterproof the deck. Within 3 years all This old repaired area only lasted a few months before the crack chasing tore through the old system.
Our system completely hides and conceals joints and cracks so they are NEVER exposed to direct water again by sandwiching high strength flexible polyester fabric between the base coat and intermediate coat.
We are the only vehicular traffic grade system in the industry that actually addresses the real source of leaks and continuing cracking in parking decks.
Now Playa Pacifica Community’s parking lot of 52,000 sq/ft is completely seamless, monolithic, waterproof, joint free, and crack free. This deck’s joints will never see the light of day.
