  • What We Do

    Many foundation problems begin with water pressure and moisture around the home. Behncke Construction specializes in diagnosing basement leaks, foundation movement, and structural damage caused by water intrusion and soil pressure.

    Section image

    CRACKED OR DAMAGED FOUNDATION WALLS

    Water pressure and soil movement can cause basement walls to crack or deteriorate over time. These cracks often allow water to leak into the basement. Our team repairs damaged masonry and concrete foundations to restore strength and stop further structural damage.

    Section image

    BOWING OR MOVING BASEMENT WALLS

    When basement walls begin to bow inward, it is often caused by long-term moisture pressure in the surrounding soil. These conditions can lead to basement leaks, structural cracks, and wall movement. We stabilize basement walls and repair the structure so the home remains safe and dry.

    Section image

    DRAINAGE AND WATER PRESSURE PROBLEMS

    Basement leaks are commonly caused by poor drainage around the foundation. Water buildup in the soil creates hydrostatic pressure that forces water through cracks and joints in basement walls. Our drainage and excavation solutions help protect foundations and reduce basement water problems.
