We have over 20 years of experience in lining ponds, lagoons and attenuation/soakaway tanks. With several gangs located around the UK, we can service almost any project. We have experience working with many manufacturers of Geo-membrane or geo-cellular product. Our skilled welding technicians arrive at the site with the equipment required, textile and seal the structure, and build all geo-cellular tanks. Catalogue Engineering uses Demtech Wedge Welders to ensure a good weld is achieved. We complete weld tests samples before we use our equipment and issue this as part of our CQA and Warranty documents.
