Unbeatable Strength

Patented double-wall I-beam construction creates thicker cells that can handle extreme weight. The cells are engineered to handle loaded 18-wheelers all day long. The TRUEGRID® MACK™ is the best choice for extreme use and permeability.

Unmovable Support

For added adherence to the ground, the patented earth-grabbing teeth dig into the sub-base or subgrade maximizing stability in heavy loads or high torque. No dust, erosion or mud can compete with TRUEGRID® MACK™.

Extra-Strength SuperSpot® Parking Markers

The SuperSpot® MACK™ design is the highest strength parking marker on the planet. With a large 4.75” diameter and domed for high visibility, the SuperSpot® MACK™ delineates and directs your truck traffic with maintenance-free markers that never quit.

Truck Yards

Drive anything you want on TRUEGRID® MACK™. Tough and strong with high-compressive strength, unmatched shear strength of the thick interlocks and torque resistance from the anchoring teeth. No more dust clouds.

Military-Grade Strength

Strong enough for the US Military, TRUEGRID® has been used on military equipment sites and troop training facilities.

Construction Sites

It doesn’t get more extreme than a construction site and work has to continue despite the mud. Stabilize the site and drive heavy cranes and cement trucks directly on the MACK™. Don’t slow down.

Parking Lots

Heavy-use drive lanes are a natural for MACK. Large, domed SuperSpot® MACK™ delineate and direct traffic clearly.

Concerned About Weight-Load Capacity?

TRUEGRID MACK is unbeatable and can handle ANY weight capacity. Just start specifying your projects to make them not only permeable but durable.
