Whites Concrete has assisted with the installation of two new Sealwall tanks for a farm-based anaerobic digestion plant in the West Midlands.
The first, a circular tank of almost 36m in diameter and a height of 4.3m, was built using 94 pre-cast concrete panels as a pre-treatment tank for agri-based feedstock.
The second, a rectangular tank, is 63m in length, and 8.4m wide, also with a height of 4.3m – was made up of 136 pre-cast concrete panels and put into operation as the main treatment tank.
Each of Whites Concrete’s Sealwall units are jointed using a tried and tested compressible hydrophilic jointing method. Steel fixings hold the precast units together, making a visibly robust system. The wall units are factory-cast to very high quality standards, and designed to the exacting requirements of the Water Retaining Concrete Code of Practice BS8007, and Eurocode EC 1992.
In addition to its pre-cast panels for AD plants, Whites Concrete also supplies its panels for Silage Clamps, including, for example, at Northern Crop Driers, where storage of 6,000 tonnes of silage for AD feedstock was required. Whites Concrete were called upon to create a design that would use the space to full effect, keeping silage dry and clean whilst ensuring that load demands would meet the bulk density.
