What is Polymer Concrete?

Polymer concrete is made from selectively-graded aggregates in combination with a polymer resin system. When combined through a process of mixing, molding and curing, an extremely powerful cross-linked bond is formed. Precast polymer concrete is reinforced with fiberglass for exceptional strength and rigidity.

Choose Polymer Concrete

  • Lightweight - 1/10 to 1/3 the weight of concrete
  • High Strength - compressive, flexural and tensile strengths three to five times higher than traditional concrete
  • Reduced Installation Costs - easy to handle, no special equipment required
  • Stable Under Freeze/Thaw Conditions
  • Impact Resistant - tested per ASTM D-2444
  • Low Water Absorption - less than 1% per ASTM D-570
  • Corrosion Resistant - resistant to alkalines, acids, weathering and other forms of deterioration
  • Cost Effective - outperforms conventional materials for longer service and lower life cycle costs
  • Nonflammable - will not support combustion
  • Nonconductive - no grounding required for the box or cover

QUAZITE® enclosures are embedded in concrete highway median barriers.
