We expertly install FIRM-FILL Gypsum Concrete Underlayments (GCU). Firm-Fill GCU is designed for use in multi-family housing, hospitality, and commercial buildings to satisfy acoustical ratings and fire codes while providing flat, quick-drying surfaces for finished floor coverings. Firm-Fill GCU range in psi from 1200 all the way up to 4000 psi and are quick drying – you can walk on it 90 minutes after it is poured and it is fully cured within 10-14 days.

All Firm-Fill Underlayments are appropriate for use over Hacker Sound Mat & FIRM-FILL® SCM-125, 250, 400 and 750.

We also install gypsum underlayment for specific use as the heat mass for radiant floors. Radiant heating is the most efficient way to heat a home because it heats the house from the bones on out. With our gypsum underlayment as the heat mass, your choices for finished floor coverings are limitless - tile, wood, carpet, laminate, it all stays warm!

We also install acoustical control mats that work in a system with gypsum concrete to be a noise-reduction package. FIRM-FILL® Sound Control Mats (SCM) are durable, lightweight sound control mats that provide a quieter environment and meets demanding project specifications. FIRM-FILL® SCM are engineered to limit impact sound transmission between floors when used in conjunction with a FIRM-FILL® Gypsum Concrete Underlayments. FIRM-FILL® SCM can improve IIC ratings 15-25 points and carry a Class-A fire rating under ASTM E84.
