Hollow dense concrete blocks are remarkably versatile in their usage in a number of building applications. These blocks serve as a secure base for fixings and are suitable for external and cavity walls. The hollow cores can be loaded with poured concrete and augmented with steel to build incredibly enduring, lightweight and powerful walls. The Hollow Dense Concrete Block can construct extraordinarily strong retaining walls with a standard strength of 7.3N/mm². We recommend this block for external walls, cavity walls, partition walls, and party walls.
Hollow concrete blocks also have an A1 Classification reaction to fire and have good sound insulation capabilities. If you are looking for a block showcasing high strength properties, the solid dense concrete block 7.3N is the perfect solution. Hollow dense 7.3N concrete block is available in one size of 440 x 215 x 215mm and is delivered in a pallet of 40 units.
The 7.3N Hollow dense concrete blocks 215mm are an economical solution for commercial as well as agricultural applications due to its production with the use of high-quality class 2 aggregates and up to 30% recycled materials. This block creates a secure base for applications of single or multi storeys and is also used extensively in refurbishments, extensions, and remodelling work.
