Root Bridging

 

 

Stalite PermaTill graded aggregates are installed over existing root systems for tree preservation where parking lots, sidewalks, driveways, streets, or patios are constructed. It allows designers to acheive new design grades and preserve existing trees as part of that design. Stalite has high compressive strength for stability, yet is half the weight of typical stone. The angular aggregates are 50 % porous, 6% moisture retentive and provide consistent drainage, aeration for the tree roots.
