I recommend for anyone in upstate NY. They waterproofed with bentonite injection and guarantee the work. They did 2 of my houses, my son, my sister and nephew's house and the walls are dry with no mess.Other waterproofers jackhammer the floors and drain water through the walls!

I have been waterproofing basements for 21 yrs averaging 4-5 basements a week. We quarantee the walls and floor will be dry by using bentonite injection method. We have an A plus rating with the BBB and A rating with Angies list (both highest ratings). While most waterproofing companies put inside drains alone the water is still coming through the walls , so they are still wet, damp, and slowly destoying the bottom of the wall. Why do they push putting up 4 x 8 vinyl sheets on the wall? So you do not see it.If your roof was leaking would you put a gutter in your attic and run it through the soffits? No. This is no different except it is your foundation. In upstate NY for free estimate call 1-800-439-4951. Jack

The few companies that do remedial bentonite injections realize the importance of customer confidence and usually have very high ratings with the BBB and Angie's List. Bentonite Waterproofing is a billion dollar industry, anything built on wetlands will use this material for waterproofing, and the only space left these days seems to be near or on wet or moist ground.
This waterproofing is done using a combination of a bentonite membrane and trowel-grade bentonite (usually mixed with butyl rubber). Manufacturers like CETCO and Carlisle sell millions of dollars of bentonite waterproofing a year worldwide. Some contractors may discount the value of exterior waterproofing without having a true grasp on hydrogeology.

I live in rural Indiana and have investigated hydroclay for the basement of my 80 year old home. I only found one company (so far) that would service my area and they felt it necessary to apply some sort of strap to brace the front wall so it wouldn't cave in from the pressure of their bentonite when it expands. They said the cracks in the mortar would be filled from the outside injection. The cost to do 3 sides of my house (30x40 footprint--about 100 linear feet) is about $10,000. Is that on par with the experience of others? ($100 per linear foot of foundation)

Carbon Fiber Strips work great to stabilize a moving wall and might have been a precaution for any wall movement during injections but more importantly the long-term health of the wall.

The injection process doesn't require a lot of pressure to get the clay in the ground, usually there's very moist or porous ground once you get through the harder surface and the idea is to fill these voids and let the hydroclay follow the water paths, filling cracks and holes along the way. The clay will absorb large amounts of ground water, swelling to fill the area but does not really "expand" and exert additional pressure.

It's probably expensive to send a crew to rural Indiana so your costs will be higher than most, I would make sure their insurance is up to date and you should be good to go.

We had our home waterproofed from the exterior using the bentonite clay injection. Reporting really great results. IN fact, we just treated our new, smaller house. It was built in 1937 so of course, there is effervescing on the basement walls. There were torrential rains in Minneapolis this summer and there was no water leakage. I recommend the Minneapolis Great Lakes Waterproofing. They guarantee their work.

Pressure pumping with Bentonite has been illegal in WI since the late 70's when the WI Dept of agriculture, Trade and Consumer Protection created the Basement Waterproofing Unfair Trade Practices. One of the companies, Meridan, closed shop but later resurfaced as Everydry.
Don't waste your time with any of these national companies and their gimmicks. Your best bet is to work with a local contractor who is familiar with your soil conditions and problems in your area.

Hello Charles, thanks for your input, unfortunately your 100 % wrong about bentonite being illegal in WI. Looks like your website might be down for now but it seems when I went through it last time you were a big proponent of interior drain-tile systems, which is fine, they do have a place and need, but not all the time especially when you want waterproofing and not water management.
I would expect a consultant to understand and evaluate all the water mitigation systems and make an informed decision, not a blanket rejection. The fact is that bentonite is the world’s number one waterproofing material, no other product, both natural and man-made, can compare to its ability to self-heal over cracks and not become brittle or lose its plasticizers and fall apart.
It’s refreshing to see new people present ideas but when your down for just one post it looks like you’re pushing your company instead of comparing information.

I had Bentonite injected around my whole house in 2011 and to this day my basement is still wet. They came out and put more in 3 times and I still have water. I have put up more gutters and sealed cracks in the basement walls, I even took some of my sidewalk out and put sod there and added soil around my basement. MY BASEMENT IS STILL WET
