Hollow design with lid, Polybase is filled with stone or sand for mass. Excavated material is usually suitable.
Gasket seals, Neoprene gaskets are used to seal the cabinet base from water/gas ingress removing the requirement for toxic resins.
Factory installed earth cable with additional earthing points, Earthing materials, tools and test meters are not required on site.
Moulded Lifting Handles, Polybase is designed with handles and lifting strap points to facilitate easy handling.
No concrete or cement required, See above.
A Hiab truck/crane is not required.
Once the ground has been excavated and the ducts have been installed, a Type 1 stone bed is then laid and Polybase is lowered into position over the ducts.
The lid is removed and Polybase is filled with the spoil arising from the excavation or sand/aggregate.
The lid is then replaced and the cabinet root is fixed into position with the nuts and washers (provided).
A temporary cabinet can then be installed, freeing up the HIAB lorry to exclusively lift the permanent cabinets into position.
