Deck Sloping with Epoxy & Sand
"Drainage" - Priority #1
So why all the fuss? We have seen in "epidemic proportions" extreme interior and structural damage from water intrusion at poorly built and waterproofed balconies, both in luxury custom homes and condominium high rises. Elevated decks that are not sloped away from the structure or have low spots that allow water to pond will eventually fail. A proper waterproofing membrane and drainage plane are two key factors for healthy decks.Our systematic approach to building or restoring failed systems has not gone unnoticed by our peers and associates in this market. We continue to work closely with General Contractors and Architects to educate builders and property owners of the signs of failures and specifications for solutions that LAST.
Look for the Signs
If you notice water standing anywhere on the deck it will seep into the substrate and breakdown most waterproofing membranes. This emulsified material will usually leech out over the edge from underneath the stone or tile deck topping causing unsightly stains. Leeching of effloressence is a common sight, and is some cases a natural occurrence, but sometimes it can mean something much worse.
Moisture traveling behind the stucco system will cause blistering and you may notice a chaulky paint surface, columns below the deck may have drip stains as well. Check your door thresholds at the deck and any sign of interior moisture.
The Sloping Process
The proper sloping of an elevated deck is usually performed during the new construction process. If not, we can still help. Regardless if your deck is concrete or wood framed, a proper slope is needed to allow water to drain to the edge to escape.Below is a document consisting of a brief description of the process of the epoxy application at an existing balcony.
