Application

Suitable for use in the following walls:

  • Large, external wall panels are required, e.g. sheds, bunkers, retaining walls.
  • Some or all of the cores can be filled with concrete and steel rebar to form extremely strong, reinforced walls with high resistance to lateral loads, ideal for lining swimming pools, ponds etc.
  • Inner and outer leaf of cavity walls over three storeys, internal partition walls, Part E and robust details acoustic separating walls, block and beam floor infill, foundation walls below DPC, decorative facing walls.

Description

Hollow dense concrete blocks suitable for agricultural and commercial applications.


Features and benefits:

  • Manufactured to BS EN 771-3.
  • Strong, reinforced walls can be constructed quickly and economically.
  • Manufactured from Class 2 aggregates and consist of up to 20% recycled raw material.
  • Standard texture finish provides an excellent surface for mortars, renders and plasters.
