Bituthene liquid membrane is applied to sharp edges and all underground corners. (July 20, 2005)
The crew carefully applies the Bituthene membrane to all underground walls.
Bituthene membrane is first applied to the footing.
In shingle fashion, Bituthene is applied up all of the walls.
Hydroduct 220 on the walls carries underground moisture to Hydroduct Coil; this
then carries water away from the footing to a downhill drain. (July 24, 2005)
Thermadry underground insulation keep warmth in during the winter and has built-in
drainage channels to relieve hydrostatic pressure against underground walls.
A conventional french drain, which will be covered with gravel, is seen at
the bottom of the footing. Cleanouts were installed in case this ever clogs.
In case 3 drainage systems weren't enough, a fourth french drain system called EZ-Flow
was installed above the other three. While most buildings are built with just one drain
system, this redundant system will ensure no water ever enters the structure.
