Type 8 Polymer Concrete Pit

SKU PCP8 Category


Polycrete® (polymer concrete) pits have excellent insulation properties, high mechanical strengths, chemical resistance and zero water absorption, which makes them ideal as electrical and communications enclosures. Lighter and therefore less cumbersome than traditional concrete pits, only large polymer concrete pits require special lifting equipment.


  • Manufactured from chemical and corrosion resistant lightweight polymer concrete
  • Pit bodies – 100% non metallic, insulated construction with an electrical resistivity rating of 1×10 8 / sq. (identical to concrete without steel reinforcing)
  • Easy to fit and seal dividing walls
  • Easy to handle & cut for cable entry penetration
  • Range of anti-slip lids and access covers for all load classes to Class G (AS 3996)
  • OH&S friendly steel lids not exceeding 25kg
  • IP ratings up to IP4X (AS 60529) – enclosure protection against ingress
  • Aesthetic, recessed access covers for infill of pavement material to complement or match surrounding pavement
  • Steel lids and access covers are hot dip galvanised to AS 4680
  • Access covers are weather resistant
