Multifamily Flooring in the Twin Cities
A 5-story multifamily building needs gypsum underlayment on every floor for fire rating and sound control, finished flooring in 200+ units, carpet tile in corridors, and tile in bathrooms — all sequenced behind the framing crew, ahead of the cabinet installer, and compliant with STC/IIC codes that the building inspector will verify before the certificate of occupancy. ATR Floors is a USG Levelrock certified installer and a full-service commercial flooring contractor — gypsum and finished flooring under one contract, from one project manager, on one schedule.

Why Multifamily Buyers Choose ATR
Most multifamily GCs hire one sub for gypsum and another for finished flooring. That means two schedules, two project managers, and a gap between gypsum cure and flooring installation where responsibility is ambiguous. We eliminate that gap.
USG Levelrock® Certified Gypsum
Certified installer of the industry-standard fire-rated, sound-control underlayment for wood-frame and steel-frame multifamily. Truck-mounted and trailer-mounted pumps handle 15,000+ sq ft per day on mid-rise and high-rise.
Single-Source Underlayment + Floor
Gypsum pour, cure verification, substrate prep, and finished floor — LVT, carpet tile, tile — under one contract with one accountability point. When there is a substrate issue, we own it.
STC/IIC Code Compliance
Minnesota Building Code requires specific Sound Transmission Class and Impact Insulation Class for multifamily floor/ceiling assemblies. We know which UL-listed assemblies meet the spec and how to document compliance for the building official.
Punch-List & Turnover Scheduling
Every day a unit sits vacant is lost NOI. We staff and schedule unit turnovers to match your leasing calendar — tear out, prep, install new LVT or carpet, and return the unit in 2–4 days.
Mid-Rise & High-Rise Pumpable
Pump systems that push gypsum to the top floor without losing consistency. We coordinate staging, elevator access, and material delivery with the GC's site logistics plan.
New-Construction Moisture Testing
Fresh concrete slabs retain moisture for months. ASTM F2170 in-situ probes and VersaGuard molecular barrier when needed — preventing the LVT bubbling and adhesive failure that show up 12–18 months after a renovation.

Services We Provide for Multifamily
Frequently Asked Questions
Yes. ATR Floors is a USG Levelrock certified installer. We follow USG's installation protocols, use their specified primers and products, and deliver the fire and sound ratings your architect specified. Certification means our gypsum installations are backed by the manufacturer's system warranty in addition to our own 2-year workmanship warranty.
The specific ratings depend on the complete floor/ceiling assembly — gypsum depth, joist type, insulation, resilient channel, and finished flooring all contribute. Common USG Levelrock assemblies achieve STC 50-60+ and IIC 50-60+ depending on configuration. We work with your architect to confirm which UL-listed assembly meets the required ratings for your jurisdiction.
