Basement Wall Crack Low Pressure Injection

325_man · 12-07-2012, 11:13 PM

Guys,

I found several cracks on my basemen walls. They don't leak waters (at least not yet). The house is 7 years old and it is in Manassas, VA area.

I am planning to seal them with epoxy or polyurethane low pressure injection.
My guess is that the cracks don't grow hence I am thinking to use epoxy injection. If you think I should go with polyurethane injection, please let me know.

I am considering one of these two. Let me know if any of you have experience with any of them, or if there is other that is more economical

I looked in Lowes, but they don't have it

Why are you going to use epoxy or poly,when you can achieve the same result with hydraulic cement, those two products are quite pricey.

The advantage of epoxy versus hydraulic cement is that the epoxy is low viscosity, hence can be injected deep into the cracks using the special injectors. Hydraulic cement cannot be injected deep into the cracks using generally available tools and equipment. The epoxy will do a very nice job sealing the cracks, and if the cracks do not expand any further, the repair will be permanent.

Very interesting explanation,and that's a pretty big if with the epoxy or poly costing a couple hundred dollars.

" and if the cracks do not expand any further, the repair will be permanent."

Epoxy is pretty rigid after it sets, but urethane is going to have more "give". I would assume your house will continue to settle/move with the seasons and over the years. Plus it expads as it sets.

we routinely inject conc wall crks w/hydrophyllic polyurethane to stop wtr leaks,,, hydraulic is used ONLY for 'buttering' the crack so the injected mtl flows UP to the next port placed in the crk,,, think we're paying about $50 per tube (const supply house),,,we inject w/2-ram gun hand-pressure ( caulking gun ) we'd never use hydraulic alone for stopping leaking crks as we guarantee the work )

ps - both sources you post'd are good
