High-Strength Flooring Solutions

Levelrock®

Floor Underlayment Selector

With its wide range of installation and performance benefits, poured underlayment is becoming the choice for more residential, commercial and institutional construction projects than any other type of underlayment.

Performance

Higher StrengthThe LEVELROCK® brand family of floor underlayment products offers a higher range of compressive strengths than any other poured underlayment product. That means no flaking, no dusting, no chipping and no cracking. LEVELROCK floor underlayments provide exceptionally durable, acoustically superior floors that consistently deliver best-in-class performance.Superior QualityWe’ve rewritten the book on quality assurance. LEVELROCK floor underlayment is installed by a network of trained, authorized contractors, supported by USG quality control teams. The result is a complete design/build solution that ensures reliable performance, industry-leading quality and superior value.

LEVELROCK Floor Underlayment Selector

Strong LEVELROCK floor underlayments deliver compressive strengths from 2,500 to 8,000 psi and are formulated to minimize

the potential for shrinkage cracking. The high-strength formulation protects against wear from trade traffic during

construction and from forklift traffic in warehouse settings, ensuring long-lasting performance. Every underlayment

pour is tested for compressive strength according to ASTM standards, so you know exactly what performance you’re

getting. For residential, commercial or institutional floors, LEVELROCK underlayment delivers the strength your job requires.

Lightweight LEVELROCK floor underlayment is one of the lightest-weight cementitious underlayments available. For every quarter-inch

of thickness, you’ll add approximately 2.4 - 2.7 lbs./sq. ft., with a dry density of only 115 - 130 lbs./cu. ft.

Quiet During application, the underlayment slurry mix fills cracks and voids, eliminating sound channels. The addition of

LEVELROCK™ SRM-25™ sound mat or SRB™ sound board can increase acoustical performance to exceed code requirements

in recommended systems.

Safe LEVELROCK underlayment systems (including all sound-rated systems) are Classified by Underwriters Laboratories.

One- and two-hour ratings are available for wood frame floor/ceiling assemblies, and four-hour ratings are available

for precast concrete floor/ceiling assemblies. For the most up-to-date list of UL assemblies, visit www.ul.com.

Versatile A full range of products provides the flexibility you need. Concrete or wood floors, thin to thick pours, pumped or mixed

with a drill in a bucket – there’s a LEVELROCK product to meet your specification. Different LEVELROCK products accept a

wide variety of floor coverings, including carpet, ceramic tile, wood laminate, hardwood, vinyl, and approved epoxy or

stained coatings. Some products can also be used as a wear surface.

Cost Effective LEVELROCK underlayment installs quickly and cost effectively. Depending on the floor layout, up to 30,000 sq. ft. of

LEVELROCK underlayment can be installed in a single day, allowing light trade traffic to resume within 24 hours.

Benefits

Poured cementitious underlayments that deliver exceptional compressive strength, sound control and fire-resistance properties.

Establishing a new standard for poured flooring performance and quality, LEVELROCK underlayment is an ideal solution for both renovation and new construction. With trained, authorized applicators who ensure quality control, you can expect the same high-quality results on every job.

Safety First!Follow good safety and industrial hygiene practices during handling and installation of all products and systems. Take necessary precautions and wear the appropriate personal protective equipment as needed. Read material safety data sheets and related literature on products before specification and/or installation.
