REFLECTIVE CRACKING

THE GEO COMPOSITE ADVANTAGE

Crafco Geo Composite will effectively seal moisture from concrete or asphalt surfaces while dispersing stress associated with reflective cracking of overlaid pavements.

Easy Fast Installation = Long Lasting Cost Effective Results

PavePrep SA is a heavy duty, high strength geo composite self-adhesive membrane used to reinforce and waterproof pavement cracks and joints, to reduce reflective cracking of asphalt concrete overlays, and as heavy duty bridge deck waterproofing membrane.

PavePrep SA is composed of a flexible, high strength woven polyester reinforcing fabric and a bottom layer of non-woven heat resistant polyester fabric and a bottom layer of non-woven heat resistant polyester fabric with a polymer modified asphalt self-adhesive layer and removable release liner.

BENEFITS OF GEOMEMBRANE

  • Reduces Reflective Cracking
  • Stress Relief Interlayer
  • Extends Overlay Life
  • Waterproofing Membrane

CRACK SEALING

CRACK SEALING IS THE SINGLE MOST IMPORTANT STEP IN ASPHALT PRESERVATION

Sealing cracks will prevent water from getting into the cracks and causing further deteriorations. Cracks that are not sealed will eventually result in pot holes, surface depressions large crevices and sub base failure. This will result in very costly repairs and in extreme cases it may require a replacement of your road parking lot or driveway.

Contract Sealing uses only the highest proven quality sealant to fill the cracks and extend your pavements life. Studies have shown that for every $1.00 spent on crack sealing, saves $6.00-$8.00 in rehabilitation cost. With other treatments, costs are several times more per square metre.

 

 

BENEFITS OF SEALING

  • Reduces pot holes
  • Is the lowest cost preventive maintenance
  • Protects your sub base from costly repairs
  • Extends pavement life
  • Cost effective
  • Protects your investment
