Concrete hollow facing block for retaining wall.
It is recommended to consider low permeable granular material as a base material and this soil layer is placed on foundation soil.
Thanks to the magic of the hollow core these blocks can easily be filled with reinforcing steel and concrete to create a massive structure with enough strength to solve some of the most frequent challenges faced by retaining wall designers and installers including attaching a barrier to the top of a retaining wall and creating flood protection walls.
Enviro wall a versatile reversible block allowing a variety of visual effects.
The design is based on casting full depth rebar voids through the blocks.
Introducing the redi rock freestanding hollow core also known as magic block tm.
The reinforced block wall is the more economical solution for taller walls than gravity walls.
As per the definition given in the indian standard is 2185 part 1 2005 hollow concrete blocks are having one or more large holes or cavities which either pass through the block open cavity or do not effectively pass through the block closed cavity and having the solid material between 50 and 75 of the total volume of the block calculated from the overall dimensions.
The blocks are available in a standard face size of 440 x 215mm and in thicknesses of 140mm and 215mm in a standard finish suitable for rendering.
They are manufactured to bs en 771 3 using class 1 limestone aggregates.
About 60 of these are brick making machinery 1 are blocks and 1 are wooden toys.
Enviro wall is a cost effective and simple retaining wall system.
Behind the wall lay geo textile fabric over the soil and backfill with drainage material such as recycled crushed concrete.
These holes or cavities reduce the total cross sectional area of the block and hence the weight of block.
Fill and backfill the wall pour concrete into the core of the blocks and compact by ramming with a bar leaving to cure for at least seven days.
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 and industrial buildings storage bunkers pond and pool linings and retaining walls.
Our hollow blocks are manufactured from high quality class 2 aggregates and consist of up to 30 recycled raw materials.
The wall rebar is then placed into the wall and fixed using a cement based grout.
Rebar cast into the foundation is lapped onto rebar located within the vertical voids.
We offer two sizes of hollow concrete block to complement our range of solid dense blocks.
