The durability of our Wells is guaranteed up to 100 years. The flat bottomed base is fully lined in HDPE (High Density Polyethylene) with T-Grip Technology welded on the joint in our factory. Covering also the extension elements, it is possible to operate on site to weld the joint in order to make the entire well perfectly waterproof. The intervention is carried out by a specialised personnel of Coprem Service equipped with a license according to UNI EN 1307 for class 7 PE 7.5+3 PE 3.2 and DVS 2212:2008 for class ll-1.1.
The HDPE liner guarantees protection of the concrete even in the presence of aggressive chemical elements. The plastic inlets (or with incorporated gasket in the case of HDPE pipes) guarantee the perfect seal of the joint.
