WEBAC_® 1660: injection resin with excellent compressive and bending tensile strength for the stabilization of concrete and masonry

WEBAC_® 1660 is a PU injection resin with high compressive and bending tensile strength usually only found in epoxy resins. WEBAC_® 1660 is used for sealing, bonding and stabilizing structural elements. WEBAC_® 1660 is suitable for filling cavities and gravel nests and for structural bonding, for instance in case of dry voids in quarrystone and unconsolidated rock. It can also be used for the static stabilisation of concrete and masonry as well as for injections via injection tubes. When mixed with water, WEBAC_® 1660 has a slight foaming tendency. Under dry conditions WEBAC_® 1660 cures to form an almost pore-free, compact, solid and watertight material.
 

Reconstruction of the Mandelholz Dam: stabilization of concrete with WEBAC_® 1660

WEBAC_® 1660 was, for instance, used for the reconstruction of the Mandelholz Dam, a barrage system located in the Harz mountains of Germany. The 28 m high earth-fill dam has an integrated concrete inspection walkway which was partly made from badly compressed concrete. In the course of time, leaks formed and endangered the walkway’s stability. The reconstruction comprised the sealing of the structure against penetrating water and the stabilisation of the pervious concrete at the same time. The injection of WEBAC_® 1660 was the ideal solution for closing all leaks and cavities obtaining structural strength. The inspection walkway could be successfully stabilized.
