I have about 600 sf of below grade 12" solid filled reinforced CMU wall I need to waterproof. The owner bought some Masterseal 5000. He said that's what the contractor supply house recommended. Never used it before.
Any recommendations? Thanks in advance
Water management is more important than the membrane I think, but both are important.
The drain and backfill will handle all the ground water.
We are installing 4" and 6" drainage pipe surrounded by class A rock next to the bottom of the wall. Still need drainage board?
While on the subject of drainage,this may be helpful to elaborate on. The perforated pipe (sdr #35 not black "slinky") is best IMHO. By all means,run pipe to daylight if possible (no pumps to maintain or power outages to contend with)
If a pump and sump basin is needed,place them OUTSIDE. It makes no sense to place it in the interior of the building. Why invite the water inside only to figure out how to pump it back out ?
I agree, which is why the dimple board has a good function os a bondbreak between the soil and the foundation. Frozen soil can grab onto a tarred foundation with no problems
