Ultra-Shallow Profile Shear Connector Structural Subbase Source Control

Ultra-Shallow Profile

The ultra-shallow profile promotes stormwater infiltration over the largest area possible, including under traditional and permeable pavements.

Shear Connector

Shear connectors prevent the modular units on top of each other from shifting or sliding sideways, creating a stable stack.

Structural Subbase

The ultra-high-strength (104 psi yield) safely and reliably transfers traffic loads to subgrade soils replacing large volumes of hauled subbase stone.

Source Control

Modular units with 95% void ratio interlock with patented lateral connectors to create a monolithic stormwater management system eliminating the need for an end of line pond and tank.
