Project: Roof Deck Renovation, Washington, DC
PROBLEM
This disaster roof deck had ongoing leaking issues from day one. The trial and error method of waterproofing with various unsuccessful products was frustrating and expensive.
 |
| Asphaltic tar was an inadequate waterproofing method. |
When last addressed, the leaky concrete deck was coated with an asphaltic tar (pitch) and covered with green outdoor carpeting. The deck was not level, had ponding water issues and was quite the eye-sore.
 |
| The unattractive outdoor carpet does nothing for aesthetics or protection. |
The owners of the home wanted an attractive surface that would once-and-for-all provide reliable waterproofing they could depend on.
DURADEK SOLUTION
Duradek was selected for this deck renovation because of its roof grade waterproof protection and its ability to be installed on wood or concrete substrates. Additionally, it could provide the attractive surface the home owners were looking for and would require no ongoing maintenance.
 |
| The substrate was prepared with adequate slope. |
A 1/2 inch cement board was installed over a mortar base to provide the prepared substrate for the Duradek membrane. This allowed the deck to be leveled and sloped to the proper grade to the existing through wall drains and ensure the building envelope was protected.
 |
| Duradek vinyl now provides a completely waterproofed roof deck. |
JOB NOTES
Decks over structures are great! They add valuable square footage, which is especially valuable in congested city living.
This 50 year old structure had leaked from the time it was built. The roof deck was replaced with different material over the years 4-5 times. Nothing worked...until Duradek.
 |
| Now the deck can be enjoyed stress-free! |
