Tensar GlasPave™

Tensar GlasPave™



The GlasPave™ Mat’s waterproofing capabilities are well suited to lower volume pavement surfaces. Its geosynthetic, non-woven polyester matrix enables an asphalt binder to fully penetrate and fill voids within the matrix, limiting the infiltration of surface moisture into the granular layers of a pavement structure, ultimately preserving the strength of these layers. The matrix design also promotes a quick, strong bond with a variety of asphaltic tack coats.

  • Reduces the amount of AC tack coat required compared to other waterproofing fabrics
  • Reduces costly road repairs and lane closures associated with reflective cracking
  • Decreases labor costs with quick and easy installation procedures
  • Reduces waste with a choice of roll dimensions
  • Ensures thermal stability during installation to eliminate the risk of product shrinkage as it’s installed
  • Remains fully millable and recyclable after its service life


LUCKENHAUS STAR Grid™ G-PS and STAR Grid G+PF fill the need for an all-inclusive geosynthetic reinforcing element for asphalt pavement overlays. These innovative products, when properly installed in conjunction with an asphalt concrete (AC) overlay, extend the overlay’s service life and reduce routine maintenance. Their high-strength, high-modulus structure reinforces the overlay while interrupting reflective crack propagation from the old surface.

Although paving fabrics are effective moisture barriers and can absorb slight differential movements between the old and new surfaces, they do little to reinforce an overlay. STAR Grid G+PF and STAR Grid G-PS are designed specifically to reinforce the overlay, while also controlling the reflective crack propagation. Asphalt overlays reinforced with STAR Grid fabrics result in significantly longer life.
