Ventloc® provides superior wind uplift resistance at wind speeds up to 130 mph. Designed with tongue and groove sides and a patented venting edge that enables the rapid transfer of over paver to under paver pressures, this unique combination results in a significant enhancement of lightweight paver system wind uplift resistance. The patented interlocking tongue and groove design creates a monolithic paver surface in which an individual paver is no longer the weakest link.

Sized at 11 3/4” x 17 5/8” x 2”, Ventloc® is stocked in a Natural color with a Natural finish. Ventloc® is available in all of Hanover’s standard colors as well as a Tudor® finish. Additional colors are available when quantities permit. When reflective properties are important, Glacier White is available. U.S. Patent #5,887,397 and other patents pending.
