GridSeal® is a composite reinforcing system, developed by Ooms Avenhorn Holding bv, combining GlasGrid®, CompoGrid® and a membrane of polymer modified bitumen.

Depending on the circumstances, GlasGrid® is covered with 1.0 to 2.5kg/m2 hot sprayed Sealoflex®-SC or SAM-C and then treated with approximately 7kg/m2 crushed aggregate.

  • excellent and durable visco-elastic bond between the existing pavement and new overlay
  • good interlock
  • durable water-proofing of the underlying pavement structure
