USG LEVELROCK®
Premium Poured Gypsum Floor Underlayments
The following Underlayments may be specified from 2500psi up to 8000psi and are walkable 90 minutes after the area has been poured.
levelrock® 2500
LEVELROCK® 3500
LEVELROCK® 2500 offers the highest compressive strength in its class, providing low-thickness applications over plywood subflooring in single-family, multi-family and hotel/motel construction. This underlayment helps maximize sound isolation between floors/units and may be used with a Levelrock® brand sound mat or sound board for improved STC and IIC ratings.
• Pourable before drywall to control moisture and mold
• Installs at rates up to 40,000sf per day
• Applies at thickness of 3/8-in. over concrete, 3/4-in. over plywood to 3-in.
• Compressive strength: 2,500-3,500 psi
• Ideal for wood-frame and multi-family construction
LEVELROCK® 3500 provides superior performance for higher-traffic areas in both wood-frame and light-commercial construction. This underlayment also provides exceptional sound resistance and may be used with a Levelrock� brand sound mat or sound board for improved STC and IIC ratings.
• Installs over wood and concrete subfloors
• Meets vinyl-industry commercial specifications
• Applies at thickness of 3/8-in. over concrete, 3/4-in. over plywood to 3-in.
• Compressive strength: 3,500-4,500 psi
• Great alternative to concrete floors in light commercial and renovation applications.
LEVELROCK® 4500
LEVELROCK® Radiant Heat
LEVELROCK® 4500 provides a smooth, hard underlayment surface over concrete slabs, pre-stressed concrete and concrete planks. This underlayment accepts a variety of floor coverings and exceeds commercial vinyl-floor-covering requirements.
• Allows traffic within hours of installation
• Exceptional surface hardness resists indentation
• Applies thickness of featheredge to 3-in.
• Compressive strength: 4,500-5,500 psi
• High compressive strength for commercial, institutional and rehab construction
• Available as early exposure for fast return of trades.
LEVLEROCK® 2500 & 3500 Radiant Heat floor underlayment provides tough compressive and surface strengths for long-term resistance to the trade activity typical of a commercial construction site. This non-shrinking formulation locks radiant heat tubing in place to prevent noise and tube chafing, and it prevents the high temperature of radiant heat systems from breaking down the floor matrix.
• Accepts virtually all types of floor coverings including ceramic tile, carpeting and wood
• Applies at thicknesses of 3/4-in. above tubes to 3-in. or 1 1/2-in. typical over 1/2-in. pex
• Specify Compressive strength: 2,500-4,500 psi
• For electric and hot water radiant heat floor installations in residential & commercial construction.
