Basement Waterproofing in Chana, IL

Challenge

A homeowner in Moline, IL, contacted MidAmerica Basement Systems to address chronic moisture issues in their basement. The space was suffering from high humidity levels and active water intrusion, which created an uncomfortable environment and threatened the structural integrity of the home's interior. The objective was to transition the basement from a damp, unconditioned space into a clean, dry, and usable area.

System Design Specialist Andrew Sager performed a comprehensive site evaluation to identify the primary sources of moisture. Andrew noted that groundwater was seeping through the foundation walls, while high ambient humidity was being trapped within the porous masonry.

To provide a permanent solution, Andrew designed a multi-layered protection strategy. This plan centered on isolating the home from the earth’s moisture using a combination of drainage matting to manage hydrostatic pressure and a high-performance vapor barrier to seal the environment.

Foreman Jacob Schultz and his production crew managed the technical execution of the project. The installation process involved two critical phases:

Sub-Floor Management: The team first installed specialized Drainage Matting across the floor and up the footings. This dimpled membrane creates a dedicated space for water to flow freely toward the existing drainage system, preventing it from ever reaching the new floor surface.

CleanSpace® Encapsulation: Jacob’s crew then installed the CleanSpace® vapor barrier. This 20-mil thick, polyester-cord reinforced liner was mechanically fastened to the foundation walls. Every seam and spike head was meticulously sealed with waterproof tape and caulk, creating a permanent break between the damp foundation and the interior air.
