    When a foundation wall cracks do to movement, it must be repaired. Carbon fiber straps or epoxy are an appropriate repair to regain structural integrity. Polyurethane can be used to prevent water from penetrating the wall. Cracks wider than 1/8 inch are cause for concern.

    Installation: The crack is first evaluated and cleaned out. Then either an epoxy or polyurethane is injected in the crack, Or carbon fiber is installed over the crack.

    Many times a leaning or bowing wall can simply be braced in its current state. Using this method eliminates the need to excavate on the outside, and lowers the cost of the repair significantly. When bracing the wall, the I-beams are used in the same manner as when straightening the wall. The braced wall will not be straighter than it was, but it cannot ever get any worse.

    Installation: Steel I-Beams are installed upright along with Joist brackets which will in return stabilize and or improve the integrity of the wall.

    Have a basement that just won’t dry out? or have 100 year-old foundation? Leaks can be stopped with an interior or exterior drain tile systems.

    A drain tile system is a collection of pipes installed around your foundation and discharged to a sump pump or daylight. The pipes are perforated to allow water to drain into them. They are designed to keep the water table far below the bottom of the basement floor, this controls the capillary action or wicking of water or water vapor on to the basement floor.

    You live in a flat or low-lying areas that hold and trap water.
    Your basement has water intrusion from cracks and floor joints.
    Mineral deposits showing on walls and floors from excess moisture.
    You have a finished basement that contains costly items you want to protect against water damage and subsequent mold growth.

    50% of the air you breathe in your home is the same air contained in your crawlspace from a phenomenon called the stack effect. Crawlspace encapsulation significantly cuts down mold, mildew, and allergens. And has been known to help asthma sufferers have less symptoms at home.

    Installation: Before any plastic or vapor barrier product is installed, it is very important to check for any other issues. Once the vapor barrier is in place it can hide these issues.

    A wall leaning or bowing more than 2 inches, should be pushed back into place. Restoring the integrity of the foundation. This can be accomplished by using wall anchors or steel i-beam braces.

    Is your front porch stooping? Your sidewalk slouching? Concrete leveling (also called mud jacking or slab jacking) may be the answer. It is highly recommended concrete leveling is performed when concrete has settled a half inch or more.

  • Quacker's Waterproofing : Customer Reviews

  • 5 Star Review
  • We had a leak in the basement wall under our stairs on Thanksgiving Day. We called that Friday and left a message. Quacker's called back that same day to make an appointment to look at the crack and give an estimate. They showed up on time to do the work and performed the work in an efficient, professional manner. A transferable warranty showed up on January 6, 2001 just as promised. I would definitely hire this company again.

  • Quacker's was easy to work with, showed up on time, and did an excellent job for me. The person that repaired my foundation wall took extra time to explain the process as he worked. I would definitely use this company again.

    - Margaret - Saint Charles

  • They scheduled an appointment and then actually called that day to ask if they could come earlier. He finished the work in about an hour and left no mess behind. The crack has held, even through the hurricane remnants from late summer to early fall of this year.
