Our Services

Exterior Foundation Coatings

Our team applies advanced waterproof coatings to the outer foundation walls, creating a protective barrier that prevents moisture from seeping into the structure. This method is highly effective in managing water saturation caused by Anchorage, Alaska’s snowmelt and rain, reducing hydrostatic pressure and minimizing long-term damage.

Interior Waterproof Sealants

When exterior access is limited, we apply interior sealants to basement walls and floors. These waterproof materials form a vapor barrier that resists moisture intrusion, helping control humidity levels and protect finished spaces from water-related issues like mold or dampness.

Foundation Drainage Systems

We design and install custom drainage solutions, such as French drains and sump pumps, to redirect groundwater away from your foundation. These systems are critical in Anchorage, Alaska’s freeze-thaw environment, where shifting soil and snowmelt can contribute to excess water pooling around the foundation.

Crack Injection and Repair

Structural cracks in the foundation can allow moisture to enter and weaken your home over time. We use high-performance epoxy and polyurethane injections to seal foundation cracks, restore stability, and block future water infiltration with long-lasting results.

FAQ's

  • What is foundation waterproofing, and why is it important in Anchorage?

    Foundation waterproofing protects your home from water intrusion by sealing foundation walls and drainage areas. In Anchorage, where freeze-thaw cycles and snowmelt are common, it’s essential to prevent moisture damage, basement flooding, and long-term structural deterioration.

  • How do I know if my foundation needs waterproofing?

    Common signs include water stains, damp basement walls, mold growth, musty odors, or foundation cracks. In Anchorage, shifting soils and melting snow make these issues more likely, making professional inspection a smart step.

    We offer exterior membrane application, interior sealants, drain tile systems, sump pump installation, and grading improvements. Each method is chosen based on your home’s foundation type, water exposure, and Anchorage-specific climate challenges.

  • Can waterproofing help prevent basement flooding?

    Yes. Waterproofing systems redirect water away from your home’s foundation, preventing accumulation and seepage. This is especially important in Anchorage where spring thaw and heavy rains can overwhelm basements without proper drainage.

    Both have advantages. Exterior waterproofing is more comprehensive but requires excavation. Interior systems are less invasive and effective for controlling indoor moisture. Our team evaluates what works best for your Anchorage property.
