Waterproofing

IHI55j

How many of you guys do waterproofing and how much a foot do you get? In ohio we are trying to get $90 to $120 a foot.

Man, I need to start a waterproofing biz.

What do you mean by waterproofing?

Probably means tarring or masonry type coating on foundations before backfilling.

One day we should sort out the meaning of "waterproofing" as we all know it. Define it and come up with a working mans specification to refer to.

The insurance company we had previously had us sign a document stating we would never do "waterproofing" My advice to all is never use the word "waterproofing" in any description of your work. Use "as specified" or something. If you write up your contracts with "waterproofing" in it and 6 years later the house is full of mold, you may be buying a house.

Well when you have 3 guys and a excavater and a skid steer with 2 dumps and have to find a place to haul the dirt to and then bring in stone and fill in the entire trench along with coating the wall and putting in all new footer drains you guys cant do it much cheaper thats why no one can make money any more because everyone think they can do it so much cheaper than they go out a year later and there is another one

SLSTech

Define what your foot equals then? LF of the footing for a basement that is about 10' in the ground - full excavation, installing waterproofing, back filling, final grading? What? Your post title is simply waterproofing, a price, no real specs listed & you wonder why people are going WTF?

There you go.
Now you're pissed enough
to start telling us what you
are charging for.
We can't tell unless you tell.
Mind readers we ain't.
Now I can guess that you are
working on existing houses
and not new construction.

Is it per square foot?
Of the wall or floor space?
Or a running foot of wall?

Hi IHI,

Welcome to Contractor Talk.

Your question was kind of vague. My Impression was you wanted to know what people got for applying a waterproofing coating to foundation walls only.

I think you could get good input if you described a typical job.

Tar in a foundation is not waterproofing, but you might fool someone into thinking it is damp-proofing.

A little black stuff and drain board is also not waterproofing, but it looks good before you backfill - just a sham since ther is no where for the water to go and no control.

A friend of mine built about 3,000 - 5,000 homes and vowed to never have a water problem in a basement. - He never had a problem and it was his standard system (no extra cost) that was installed his way with no subs since he needed control. Waterproofing does not start with a subs opinion, but with a proven plan. It does not have to cost a lot and it is the best investment a home owner can make if he has it done right and is not forced to deal with the second rate patchers and "systems" salesmen.

If you say you cant, your a loser. If you say you wont, your a quiter. Which one do you want to be?

SDC

I use a company to spray foundations
$.50 sf for "damp proofing"
$.80 sf for "water proofing"
only difference is they will break off the form pins to make sure they are flush
and no movement, and it cost more...lol. But still cheap enough to have done.
The excavator still does the drain tile and fabric and stone.

IMO, the foundation contractor should be the one knocking off the ties. That is like me grading someones yard and leaving a couple piles of rocks laying around.

I do agree with you but they like to for their warranty and the form guys never complained...

well that would be true if you werent filling the entire wall from the footer drains up to almost the surface with stone so were is the water going to be ?
but thanks for everyones reply

Ok guys. I'm not sure about your local codes but here in CT I am not allowed to install anything other than a waterproof wall coating. The complete drainage system consists of:

1. Sealed all tie holes (hand applied elastomeric sealer)

2. Apply liquid elastomeric waterproofer (two full bi-directional coats)

3. Apply drainage board to top of subgrade. (usually 2 3/8" thickness)

4. Install footing perimeter drain at bottom of footing level (4" perf. pipe in 3/4" stone , wrap in filter fabric. The botom of the drainage board sits on this drain.)

5. Install 3/4" stone 8" thick under basement slab (this is connected to the exterior drainage system via a through footing passage).

6. Pipe drainage system to daylight (downhill from footing level).

This system (used throughout New England) solves most all static water pressure issues in new and existing homes and additions. The five gallon pails of "foundation coating" applied with a brush or roller are not true concrete and block wall "waterproofers" and as we all should know waterproofing of foundations is a complete system of many components.

In high ground water / static pressure areas additional steps are taken to complete the system such as a footing to wall waterstop and internal continous dewatering with pump chamber and alarm. Some systems also require a full rolled membrane application over the liquid waterproofer for additional directional control of ground water.

We use Western Forms on our projects which are aluminum panels with a flat tie bar. This type of system yields a smooth wall finish with no nub of concrete to remove a patch as with 1" thick Duraform or similar all wood panels.

"A little black stuff and drain board is also not waterproofing, but it looks good before you backfill - just a sham since ther is no where for the water to go and no control."

Correct.....what you describe is not a true waterproof basement coating. What I described above is..........in a residential or commercial application.

When building a new home........a careful assesment of the ground water for your site (year round) and a properly installed waterproof wall system will provide a healthy start to a finished basement level.
