After installing an isolation perimeter strip, QTrbm is easily rolled onto a smooth surface. It lays flat and will not slip or move.

Simply duct tape the joints.

QTrbm is durable enough for foot traffic, pouring equipment and materials.

Pour a minimum 3/4" gypsum concrete surface that meets required sound ratings and passes structural requirements.

Prepare gypsum concrete surface for floor finish.
