Redruth Brewery 2015 - Tank Construction

Until 2015 the former 2.3 hectare Redruth Brewery Site had been derelict for many years.  Funding from the European Regional Development Fund has made it possible for land within the UNESCO Cornish Mining World Heritage Site to be designated a Conservation Area.  As part of the enabling work, Geosynthetic Technology Limited was contracted by Morcom Construction Limited to assemble and line a 165m³ Rainwater Attenuation Tank on the site. 

Our tank lining work involved off-site factory prefabrication of the Company’s highly flexible Polypropylene 1.00mm geomembrane lining product into 5 No modules.  The modules for the main tank structure were box-welded to facilitate rapid installation on site.  An unusual feature is the 8m x 2.4m protrusion from the main tank, visible in both these photographs.

The overall installed dimensions of the tank are a length of 30.4m and a width of 4.8m.  The liner, attenuation units, inspection chambers, and outer geotextile wrap were installed on site within two-and-a-half days; all in accordance with our ISO 9002 Quality Assured Operating Procedures.

The entire tank liner is of seam-welded construction (ie without any taped joints) enabling the Company to provide a 30-year Installation Warranty.

Lined Area: 165 square metres

Materials Used: Polypropylene 1.00mm / 330g/m² Geotextile

Main Contractor: Morcom Construction Limited, Par, Cornwall
