Summary
Hollow dense concrete blocks suitable for agricultural and commercial applications.
Hollow dense concrete blocks suitable for agricultural and commercial applications.
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.
