Times are tough, I understand being thrifty and looking for the best deals out there. When it comes to waterproofing your decks and patio's or any horizontal surface my thought is be cost effective and thrifty. Here are some examples from Park City, an area that is suffereing serious water related issues from a combination of product choice and poor installation.
The visible water leaking into the garage is what raised a flag. In truth this had been going on a very long time. The multiple layers had not stopped the water from leaking through, it was trapping it below and that was rotting the substrate. Here you can see how wet the wood was, it was actually puddling during the tearoff. The water was leaking out the door below and onto the deck becasue there was nothing to hold it any longer.
The failed product was coming up in large chuncks and this is what was below. This was directly above the water leaking out the garage to the diveway. As they tore off the old it was allowing more water to flow through the holes.
In our experience the details is where waterproofing gets difficult. Here there simply is no excuse for what was done. In each application of product all they did was go up to the edge of the wooden post and stop. Anyone can see that water will get into the shrinkage cracks, this will leak below and casue the wood to expand as well.
Finally to the bottom layer. Although the wood had not rotted yet you can see the rust from a layer of metal that was used, probably to help reduce movement. All it did was rust from the amount of moisture seeping in.
