BY M.SQUARED
ERC is an Authorized Installer of INFILL-CRETE™
State-of-the-art 2-part polymeric waterproofing. Zero VOCs. Cannot delaminate. Penetrates concrete from the inside to create a permanent vapor barrier — used by Fortune 50 companies and specified internationally.

What Makes INFILL-CRETE Different

Most waterproofing products coat the surface of concrete — and eventually peel, crack, or lose adhesion. INFILL-CRETE works differently: it penetrates deep into the concrete and chemically reacts with moisture to form a vapor barrier from inside the material itself. That means it can never delaminate, because it’s bonded to the concrete at a molecular level.

🔬
Internal Chemical Bond
Penetrates deeply and reacts inside the concrete — not just bonded to the surface. As strong as the concrete itself.
🌫
Full Vapor Barrier
Stops both liquid water AND moisture vapor — eliminating the humidity and mold risk that standard waterproofing misses.
🌿
Zero VOCs
No solvents, no harsh chemicals. Environmentally friendly and safe to apply in occupied buildings — no downtime required.
🏗
Any Age Concrete
Works on concrete as new as 5 days old or as old as 100+ years. Residential, commercial, and industrial substrates.
