The Problem:

Underneath the old deck boards which were cracking and breaking, the asphaltic membrane was failing and allowing water into the living space underneath.

The Outcome:

This project was more of a technical challenge than most decks and consisted of the following steps:

  1. Removing the existing deck boards.
  2. Re-Sloping the support surface to create a correct drainage flow to the exterior.
  3. Installing a new plywood substrate and perimeter flashing.
  4. Applyling the Westcoat ALX Under Tile cementitious waterproofing system.
  5. Applying a base coat of urethane waterproofing.
  6. Applying a top coat of urethane waterproofing with embedded sand for a reduced-skid surface.

Since the outer edge of the deck was curved and there was a walkway on either side, the re-sloping portion was quite challenging, and ultimately successful.

What our customers had to say:

As an attorney, I became keenly aware of the broad spectrum of relative quality performed by contractors. Your work on these challenging decks is certainly at the very top of the quality spectrum.
