Case History #121 - Private Residence in Utah

Project: Private Residence, Centerville Bench, UT

Date: Fall 2009

Problem:
This home had a tiled deck over a living space.  It was improperly waterproofed and started leaking water into the dining area below causeing water damage to the interior of the home.  The homeowners really liked the look of a tiled deck, but needed a product that would allow for proper waterproofing.

Duradek Solution:
After learning a costly lesson, the homeowners decided that proper waterproofing far outweighed the importance of the finished look.  By using Duradek Ultra Tiledek they were able to have both.  Tiledek was used to properly waterproof the area and then tile was installed.  The proven Duradek process and 10 year warranty gave the homeowners some much needed peace of mind.

Job Notes:
Less then a year later the homeowners called MBL Construction back to finish another deck on the home.

Case History #120 - A Vancouver Home

Project: Private Residence, Vancouver, BC

Date: June 2009

Problem:
This sundeck was originally waterproofed with Duradek Supreme Granite. Approximately 6 years ago slate was applied over the Duradek membrane. The contractor installed CPU directly over the Duradek, drilling right through the membrane itself. Over time mortar and tile sealants were applied to maintain water tightness. At first this seemed like a successful tile application, however it didn’t take long for the homeowners to realize something wasn't right. While on the surface this deck looked great, underneath there were hidden issues. Efflorescence, a deposit similar to sea salt, had started to show through the tiles and down the sides of the fascia-board.

Duradek Solution:Insufficient and improper mortar allowed water to soak in and sit in areas where there was no mortar coverage. Exterior tile practices call for 95% coverage as well as a mortar with a low permeability. Another issue was the improper tile used on the deck. An interior tile will not last long when facing exterior elements day after day. The final and most damaging issue is the waterproofing. While CBU is recommended to stabilize the tile, it should always be installed underneath the membrane, ensuring a watertight, strong structure. By using Duradek Ultra Tiledek, the homeowner was given peace of mind and a great looking deck, inside and out.

Job Notes: Even though the original Duradek membrane had been pierced and covered with thinset it still did its job of protecting the structure from short term water damage. This being said, proper waterproofing practices are always recommended.
