Hollow Dense concrete blocks are ideal for applications where a durable, lower-weight and high strength wall is required, either above or below dpc. The hollow cores can be filled with poured concrete and reinforced with steel to form incredibly strong walls for applications such as agricultural sheds, commercial & industrial buildings, storage bunkers, pond and pool linings and retaining walls. 
Manufactured from high quality class 2 aggregates in accordance with BS EN 771-3, these group 2 hollow units consist of up to 30% recycled raw materials.
