    About Cracked Basement Floor Repair

    Basement floor cracks are extremely common in MetroWest homes. As soil settles and hydrostatic pressure builds beneath your slab, cracks form and water finds its way in. Floor cracks are repaired with flexible injection materials, and the underlying water pressure is addressed with drainage solutions.

    The Process

    1

    Crack Assessment

    All floor cracks are identified, classified as structural or shrinkage, and checked for active water entry.

    2

    Crack Preparation

    Cracks are cleaned and routed to create a proper channel for sealant application.

    3

    Injection & Sealing

    Flexible polyurethane is injected into cracks to create a waterproof seal that accommodates floor movement.

    4

    Drainage Integration

    If hydrostatic pressure is present, sub-slab drainage is installed to relieve pressure and manage water.
