Foundation Waterproofing ?
Allen
Anyone familar w\ a system applied to block foundations, is some type of
plastic barrier stuck to the tar coating. I have been told it is helpful
channeling water down the plastic channel to the footing drain. Cost 1$
sq. ft in NJ ??? Thanks

I had called a waterproofer about covering a block foundation under
ground. He told me to buy a commercial tar waterproofing production
which calls for one layer of tar followed by a fiberglass mesh layer
followed by one more layer of tar. It seems to have worked well. The
tar product cost $16 per 5 gallons, while the fiberglass mesh was more
expensive.

I know folks who have put on tar & then applied regular 6 mil poly to that then backfilled carefully. It seems to me it would break down pretty fast, but they liked it.

It breaks down or gets torn, and then water get trapped between it and the
wall and has know where to go exept into ste structure.
Apply foundation sealer, (Tar) but be sure to clean the surface thoughly
first and make sure it is dry before you apply, install a drain tile, (
make sure it is heavy wall) that can support the weight of the backfill.
And make sure it is liad on the proper grade and has fall, water won't run
up hill, and it doesn't do any good if it is not below the floor level of
your basement.
( I make a pretty good living fixing others mistakes when it comes to
this.) And then backfill with stone or river gravel to within one foot of
the surface, so the water will follow the rock to the bottom.
(Do Not Backfill With Pea Gravel it packs with the dirt and after a few
years is ineffective.)
Also you will need to seperate the rock from the dirt. I use Geotextile
made from used rubber. but any good filter cloth will work.
Just my 2 cents,
Jim

inch or so, coverd on the dirt side with filter fabric. The tits keep a
space for the water to run down to the drain pipe below and then out.
can cover with dirt, after covering the drain pipe with rock. works
great, just put some up today.

Whatever product you use, make sure you use both the dampproofing (tar)
to stop moisture vapor, and a drain tile (such as Inca
Drain/Block...think it's made by Aztec in Asheville, NC) to stop bulk
moisture...you might also want to consider a drain tile system around
the perimeter.

Usually this is a hydrocite 500 spray or something a little thicker applied
after wards by stick/brush etc.
after the spray, followed by the black cold roofing compound, followed by a
5mil plastic,
you would place a 1" styrofoam barrier as an insulator and to keep the
sealed area from being torn
and possibly leaking water. Then you backfill the area with a high sand
content soil up to two feet
below normal elevation. Then follow with normal topsoil for the area.
The sand starts below foundation
level about 4". This also allows water to penetrate the soil instead of
the basement areas.
I spent about 20 years as a commercial building contractor (AGC and ABC
member) and heavily
involved as an industry director of the local chapter of the (CSI)
Construction Specifications Institute.
I completed over $1 billion in hard core construction volume throughout the
SouthWestern US.
I changed careers about 7 years ago after completing another goal of two
degrees (Computer
Science and Psychology). I currently work as the testing administrator in
the integration testing
facility for GTE Directories. All new products that this company
purchases or develops I geet to
try out first. Sometimes this can be considerable fun, others it is just
following a methodology
I wrote two years ago on a product requirement. I still miss throwing the
dice on bid days !
Hope this helps you and if you need further help please check out the
Thompson's Product Guide
for Sealants (section 7).
