Concrete Crawl Spaces

A well-constructed concrete crawl space keeps moisture, pests, and cold air from compromising your home. OAX Construction builds crawl spaces designed for Michigan's climate and soil conditions.

Crawl spaces are a practical foundation option for homes where a full basement isn't needed but a slab-on-grade won't work due to the terrain or drainage. They provide access to plumbing, electrical, and HVAC systems while elevating your home above ground moisture. In the Kalamazoo area, where seasonal water tables can rise, a properly poured and sealed concrete crawl space is essential for long-term home health.

Building a concrete crawl space begins with excavation to the proper depth, followed by installing footings that extend below Michigan's 42-inch frost line. We pour reinforced concrete walls and, where applicable, a concrete floor to create a clean, sealed space beneath your home.

Moisture management is a priority at every step. We install drainage tile around the perimeter, apply waterproofing to exterior walls, and can add vapor barriers on the interior to prevent ground moisture from entering your home. Proper ventilation or conditioned air systems are incorporated based on the design requirements.

For existing crawl spaces, we assess the current condition and recommend targeted repairs or full encapsulation depending on the issues present. Common problems we address include standing water, excessive humidity, sagging floor joists, and pest entry points.
