Bvbasement
Have a corner in the basement where seepage occurs during the spring and heavy rain. Landscaping / downspouts look good. An old draintile system exists w/sump pump. Would an exterior soil injection of Bentonite Clay (HydroClay) be a good idea. Can't find any good feedback about this. Only one company in the Twin Cities area appears to do this. have some concerns about additional horizontal pressure against the walls with this. Also, if applied, would it plug up the existing drain tile in the spot where applied thus backing up the drain tile furthur up the line. Any if applied in only one spot, would the water simply displace furhtur down the wall. The price is much cheaper than a brand new drain tile system. But no info from the BBB on the company (Great Lakes WaterProofing from St. Paul, MN) or in general from the web as to the pros/cons of having this done. Any feedback appreciated!!

Corner most often leaks due to crack(s) and/or other EXTERIOR openings as in these pictures http://www2.snapfish.com/thumbnailshare/AlbumID=228274929/a=122238283_111847456/t_=122238283

Homeowner just bought this house, nobody said crap to her about leak/efflorescence on wall etc, seller,home inspector etc.

The corner leaks along floor-wall joint due to exterior cracks and some other openings between top of wall and bricks.

Here is/was one Great Lakes Waterpf`g Co, went OOB http://cleveland.e-asp.net/Nis4/bbbreportaccbuscontent.asp?ID=1&ComID=0312000016003772

It`s your house, do what ya like. There are many Co`s who CLAIM they are experts and there is ALOT of FALSE CLAIMS,lies online,on Co`s websites. Some have been nailed for fraud, and sooner or later OTHERS will be as well.

See cracks here? Some at-near EXTERIOR corner. Then there are OTHER openings, some below and some ABOVE grade-level. Only way to repair/waterproof these cracks is w/exterior waterproofing. Only way to remove expanding-contracting soil and ROOTS that are against wall is outside. Termites,ants,spiders,centipedes,radon can easily enter through these types of exterior cracks

So it seems you are implying the bentonite soil injectors are not worth pursuing as an option. Any specific reasons? Sounds like exterior evacation and then waterproofing is what you're suggesting.

find,locate how/where water FIRST enters,this is what all should do.

i`m implying that over the last 30 years that most(not all) homeowners problem(s) are on the outside. Cracks,open mortar joints,openings around basement windows etc etc etc.

It`s what TIME has shown us.

Want to see more pictures of homeowners actual-problems?

Some folks have 'other' reasons as to why-how water winds up on the bsmt floor. Some include a blockage in lateral line between the street and house, many(not all)remedies for this was having an honest-exp`d plumber snake the storm trap clean out, cost usually $125-200.

Others have a blockage in tile that empties into their sump PIT. EITHER, need to snake that tile back under floor and/or, sometimes there are no openings-holes up higher in SIDE`s of PIT-wall, just under the bsmt floor. Need to drill-create holes in pit-wall to allow water to get into pit, otherwise the water can accumulate under the floor and back up,rise through floor crack(s) or along wall-floor joint.

Others may simply have some sort of leaky plumbing fixture. Still others may have a condensation problem, especially if they placed a sheeting right up against concrete basement wall(s). But like i say, and know, most (not all) HO`s problems/causes are on the outside.

Many only have 1 crack, say at-near a corner or have 1 wall that leaks along wall-floor joint due to exterior cracks...so,they will only need to repair/waterproof the corner or, 1 wall. Part of problem is there are some companies who bs people into more work/footage than needed.

Find,locate the problem-source, then fix it.

In my honest opinion, Bent.injections do not correctly repair/fix/waterproof the exterior crack(s), or other openings into/through wall, like a block wall. Sometimes there are gaps-spaces where a service line enters through wall.

Bent-injections don`t plug/patch/repair the dumb cracks and other openings that allow water to enter. They also do NOT remove expanding-contracting SOIL, they don`t remove ROOTS or porch footings...all these cause many walls to crack,leak or possibly bow inward.

Gotta physically remove these problems/causes and physically repair/waterproof cracks etc.

Scroll down and see scams, see Bent injection bill and lousy contract-invoice with NO WARRANTY http://www.e-o-f.com/foundation.html#SCAMS

I think of when somebody puts plaster over cracks on interior walls and then paints over the wall. As everyone knows the problem doesn't go away and usually comes back immediately. The reason...buildings move. Ever have a car drive by with it's radio on loud? Ever wonder what excavating next to the foundation does with or without heavy equipment?

The reason this foundation is leaking in the first set of photos is because the original coating on the wall failed or lived out it's lifespan. Replacing it with the same thing is a gamble at best.

The second photo set shows the same situation, the asphalt covering the foundation is visible in the photos and has obviously failed and the mortar deteriorated.

One of the reasons interior drain tile systems became popular the last 20 years is that the conventional way of excavating the fill around the foundation, after years of "support" for the wall, increases the risk of more failure substantially. Foundation walls will crack when they lose support. Removing the dirt around your foundation and backfilling with gravel or more dirt stresses the wall, I'm sure in both these cases the ground wasn't properly tamped leaving large voids for water to collect, posing more risks.

As you can see in the last few photos on the second set, filling in the trench with gravel will cause stress on the plastic wrap and the asphalt undercoating (notice the plastic stretching by the weight of the gravel) Over time the movement of the gravel is like sandpaper on the plastic and tar. Once water is added to the mix and the expansion, and contractions of the seasons, your looking at the same old situation.

Bentonite (Hydroclay) has been used for several decades for waterproofing. Most city dumps are lined with it to prevent liquids from leaching into the ground. Dams, tunnels, manholes are lined (on the exterior) with it. The DNR requires it when sealing a well....The reason...it's a naturally occurring water-resistant material that will cover the structure regardless if it's smooth or jagged. The National Institute of Building Science also specifies it as the only Green Method of Waterproofing.

In the case you do have a contractor show up that wants to put backfill into the street without a container, not mark off work areas (especially trenches)...listen to all his advice...You might want to check your local building codes, the homeowner could be responsible for any injuries related to a contractors negligence.

do NOT have clue. ANYONE 'MISREPRESENTING' the condition of a basement wall, of why the basement leaks, of the correct REMEDY should be SUED. Many of these posters are completely full of crap folks, they are INCOMPETENT fraudsters, believe what you like.

I forgot....You are the expert. I didn't mean to point out glaring Red Flags.

What happened with this job?

http://www.wwmt.com/news/edwards_25979___article.html/house_basement.html

The photo shows excavation on the outside of the foundation, the caved-in blocks also have a layer of that waterproofing tar you recommend above and I think I see some plastic in the dirt.

thats one of your boys, Everdry. They broke out basement-floor on the INSIDE too, THAT was the MISTAKE-INCOMPETENCE on this house/story.

and see complaints just within the last 36 months,lolol.

misreperesenting the CONDITION of a house, the condition of a basement, the condition of a basement wall,and WHY water actually enters is...FRAUD!
