We have partnered with a civil engineering company from mid wales called Evabuild. Evabuild are a national company and will travel anywhere within the UK. The link to their website is Retaining Wall Solutions.

Blockwalls offers solutions for the present and the future. We have collaborated with a leading university to develop a material matrix that offers high specification concrete at an economic price. It will be manufactured using 87% recycled materials. It will reduce the carbon content in its manufacture and contribute to the sustainability target of the construction industry. The reduction in carbon for just one block can reduce carbon consumption as much as driving 500 miles in a car!
