Foundation Waterproofing?

TurnkeyConst

Yes I have a 3 car garage to build well the back of the garage will be backfilled to 3 1/2' high. We will install a foundation drain but does the foundation also need to be waterproofed?

Yes.

This is in addition to the cheap damp proofing usually used it should be waterproofed if you are a goood contractor. It is cheap.

how about the sloping sides?

Waterproofing should always be applied on any foundation wall as well as a proper drainage system with proper fill such as washed rock. and its never a bad idea to compact the gravel also. as to avoid settling. Very important in areas which are subject to freezing and thawing...

A lot cheaper than water damage.

Thanks guys for the input had thought about waterproofing but noticed alot of other contractors are just putting in foundation drains. we will go the whole way and waterproof it just to have double protection against water!!!

I have a similar issue I'm working on. I'm building a concrete dome and the HO wants to berm/backfill (to about 4 feet) the south facing side of the house (in FL) to help cooling. I told him it's probably not worth the water intrusion headaches. Since it's a dome, there are no gutters so the roof water will run right down the sides to teh edge of the foundation...

If he persists, what product should I use to waterproof the wall? It's made of poured cement panels reinforced with wire mesh and fiber. I don't want to use tar and felt, since I've seen that leak too quickly.
