Bentonite Geotextile Waterproofing
I’m going to be using Volclay Voltex bentonite geotextile waterproofing on a project and was wondering if anybody had used it before and any problems or tips they had.

I have used bentonite, very difficult to mix thoroughly.Works well after it is mixed.You will need at least a 2"x2" pump and a large vessel or steel watering tub. Mixing could take an hour with a small pump.You may want to contact a well driller, they use bentonite to line the well hole while drilling.They could mix it for you on site in a large trough.

Dave,
I have used GCL's in my previous life building landfills and liner systems. I am not familiar with the Volclay product, but they are super liquid barriers-Very heavy though and impossible to work with if they get wet.
How does it get attached? The GCL's we used were basically puncture proof since the bentonite expands into any penetration.
I would love to see how it goes on. We just finished water proofing a basement using the Tamko product. Worked very well and I feel pretty confident with a good 60 mil of thickness.

So far all I know is that it comes in 4'x15' sheets with the sodium benonite in between two layers of the geotextile material. It is attached to the wall with washer headed fasteners. From what I've read you can't use it on CMU only on or under concrete. It gets some sort of Hydrobar tube at the bottom of the wall along the footer which drains the water off.
Special sealer(Bentoseal) for all penetrations, laps and corners to be troweled on. Whenever I see it specify a trowel I know what that means. I'm thinking that I should wear all my brand new clothes and put a big gob in my hair just to get it over with on the first day.
Sounds similar to the stuff we used but smaller. Carefull with the Bentoseal. It is slicker than.... when wet. Please post some pics. I would love to see how it goes in. Make sure it stays dry until the install.
Good Luck.
