At BlockWalls we too want to support the circular economy. We manufacture interlocking concrete blocks using recycled materials and other waste streams which supports the circular economy and significantly reduces Co2 emissions.
Concrete is the second largest commodity in the world, second only to water and it produces over 7% of the worlds man made Co2 emissions, the main culprit being the manufacture of cement.
The first question is – What waste streams and material can we use to manufacture concrete?
Conventional concrete is made from aggregates and a binder which holds it together.
In place of quarried aggregates and commercially produced cement we can use a number of recycled aggregates and novel low carbon cement types, for example:
Crushed concrete and brick rubble demolition – This material can be crushed down to 40 and 20mm aggregate.
Recycled glass from recycling plants – we have process that breaks the glass down into 10mm aggregate and fine glass sands.
Washed road sweepings.
Residues from thermal processes such as bottom ash or slags
Incinerated paper pulp sludge
Air pollution control residues
Incinerated sewage sludge ash
Alternative alkali binders
Pulverised Fuel Ash
We are working closely with university material scientists and waste industry partners to develop concretes that are:
More heat resistant
More chemical resistant

CALL 0800 880 3135
Call today and tell us about your project. We can then design it and give you the quantities of blocks you require together with a quotation. We supply all the method and risk assessments and COSHH data sheets for installation. Opening hours from 9am to 5pm Monday to Friday (except bank holidays).
Blockwalls provide innovative and efficient building solutions for green infrastructure.
Our blocks are designed and assembled to build permanent or temporary structures instantaneously without the need of expensive joining techniques or intensive labour hours that presents a cost-effective alternative to comparable steel soil reinforcement or conventional reinforced concrete walls.
They can be used to create a multitude of fire grade structures of up to 8 metres in height use support rods that are installed at the base, which provide increased stability to protect both integrity and strength.
Block formulas are stress tested to meet with British Civil Engineering industry standards and to stand the test of time. There is also a range of environmental and finishing blocks that provide a high-aesthetic finish to any job reducing your projects carbon footprint.
