Dry Rot Repair
War strategy was as follows:
Dry rot repair. We had to remove a small part of the deck down to the beams because of dry rot. Battle one won!
Drip edge flashing. Underneath the railing repair we placed new bonderized flashing along the exterior of the decking as a deck waterproofing base. Battle three, a breeze!
Sloping. This deck had pooling. This was the cause of the dry rot, as when water pools, it eventually seeps through the improperly waterproofed concrete surface. It then sits on top of the plywood sub-floor, unknown to the deck owner. Soft spots appear, and then it is too late.
So, the solution to pooling is ensuring proper sloping to allow any excess water on the deck surface to drain off the edge of the deck coating. An hour after a good rain, if your deck has deeper than a dime thickness of water accumulation, you have an improperly sloped deck. With Prestige Decking on the scene, after battle five, we are alive!
