RE: Chemical Resistant Slab Sealer

[Subject Prev][Subject Next][Thread Prev][Thread Next]



Thanks for the response.  The slab is partially exposed to the elements.  It is covered by a PEMB and open on all 4 sides.  It is located in TX so the extreme cold temperature affect is not critical.


I contacted SIKA and they did not have a product.  I will look into the other manufacturers you list.  The hardest part will be the permeability.  This is an EPA issue.   I’m supposed to certify the product used meets the hydraulic conductivity requires.  Apparently though manufacture’s don’t test this characteristic.  It’s a small area for a small producer so custom tests are a big expense for them.  Why the EPA puts out a requirement that is not a commonly measured by product manufacturers is a bit of a mystery.

Is this slab exposed to the elements?  Is freeze thaw an issue?
I would contact Prosoco, Sika or Con-Treat for a recommendation.  Specify what your performance needs are using ASTM's the hydraulic conductivity is only one aspect and should use an ASTM for that performance.

I need a product recommendation for a slab-on-ground surface sealer.  The product must give a hydraulic conductivity of less than 1x10^-7 cent/sec.  The slab is also subject to forklift truck traffic.  Any suggestions would be appreciated.
