Soprel uses the well proven International system developed by DYWIDAG-Systems International (DSI) of Munich, Germany. The DSI system is
approved by the European Technical Approval (ETA). Such tests are an
additional guarantee of excellence and competence in this field.
This new technology enhances concrete strength under both compressive and tensile
stresses. It delivers the desired prestress force, durability and stiffness.
As an engineering solution, post-tensioning is designed to exacting standards and code requirements.
Soprel has shown an excellent record and offers increased reliability. PT is widely used in the construction field including: buildings, bridges, parking structures, repair, rehabilitation and strengthening, rock and soil anchors, and slab on ground.
In bonded systems, two or more strands are inserted into a metal or plastic duct that is embedded in the concrete. The strands are stressed with a large, multi-strand jack an anchored in a common anchorage device. The duct is then filled with a cementitious grout that provides corrosion protection to the strand and bonds the tendon to the concrete surrounding the duct.
