Our Process in St. Cloud
Step 1: Assessment and Preparation
We inspect your foundation walls to determine the type (poured concrete vs. block), check for cracks, moisture intrusion, and structural concerns. Any active water issues are addressed first. We then recommend the right insulation approach for your specific foundation.
Step 2: Drilling and Injection or Spray Application
For block foundations, we drill small access points and inject RetroFoam into the hollow cores — the foam expands to fill every void inside the block. For poured concrete walls, we apply closed-cell spray foam directly to the surface from the sill plate to the floor. In some cases, we combine both methods for maximum performance.
Step 3: Finishing and Verification
Injection points are sealed and patched cleanly. Excess spray foam is trimmed for a uniform surface. We verify complete coverage and proper thickness with measurement tools. Your foundation is ready for framing and finishing if you choose to complete the basement space.
