Engineered for strength and easy installation, Hanover's GRIDLOC™ system opens up a world of possibilities for architects and designers. GRIDLOC™ is a lightweight structural support underlayment that creates a continuous fully supported, monolithic floor surface. Anything from Porcelain Pavers to interlocking concrete Prest® Brick can be accommodated; paving unit sizes and patterns are endless. GRIDLOC™ can be attached to wood joists or used with Hanover's Elevator® Pedestal System, creating a fixed roof assembly. Take it to the next level by adding GRIDLOC™ weights to meet ballast requirements and provide wind resistance.
