    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.

    How do you know if you need a sump pump?

    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.

    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.
