Hi
I own a 1927 pre Portland cement era house. My foundation is concrete with large aggregate -- stones found during excavation at house building time I guess. There is some water infiltration and humidity in the basement. I'd like to repair, waterproof and insulate the walls and install an weeping tile and sump pump, so that we can finish and use the basement. The humidity is not a problem in the winter but in summer months we run the dehumidifier all the time (we are in the Ottawa Canada area)
I've had several foundation repair companies give me quotes, and prices as well as techniques vary quite a bit. Some recommend using Platon (the rigid dimpled plastic sheet product) some say Bakor 77006 (a sort of liquid rubber product that adheres to the wall) is the way to go. The wall surface is super solid in spots and brittle in others. I am not sure what is the best technique between the two. How to ensure a good adherence of the waterproofing product and the existing wall? How to ensure you don't further damage the wall when nailing to it etc? How to ensure water doesn't get trapped and make things worse...
Thanks for any experienced wisdom.
