Pits & Risers

GDP’s supplies both concrete and polymer pits and risers which fit our range of quality grate solutions.

Concrete pits supplied by GDP are rated to Class D traffic loading and AS3600.  Precast concrete pits are typically used for stormwater drainage solutions, junction pits, car park drainage, local government works and mining works. 

Polymer Pits are lightweight and provide excellent insulation properties, chemical resistance and zero water absorption which is why they are commonly used as electrical and communication enclosures.
