Exploiting the respective strengths of Harmer Drainage Systems and Alumasc’s high performance waterproofing solutions, stormwater discharge is controlled at source; providing a valuable flood risk mitigation tool.  

Derbigum Olivine bituminous membranes, have a naturally occurring mineral upper layer that neutralises CO2 via an irreversible chemical reaction when it comes into contact with rainfall. The Olivine grains decrease in size with each reaction, however the grains are large enough to last 30 years before having completely reacted.

Blackdown Green Roofs offer many advantages for building developers, owners and users. They benefit the wider environment through their positive impact on sustainability, biodiversity and the attenuation of storm water.
