DrucHyd-2C

DrucHyd-2C is a two-component injection resin that ensures high reactivity with excellent mechanical strength and chemical stability. It is designed for consolidation and waterproofing of rocks, friable land and structures which are affected by high-pressure water, for conveying water in aquifers and for filling voids and cavities in strata. A major environmental advantage of this resin is that it does not contain halogens and CFC. DrucHyd-2C penetrates into the tiniest fissures and seals them even against significant water infiltration due to its unique and specific composition. First contact with water causes the resin to expand into a compact stable foam. The fast paced reaction quickly blocks infiltration water and the following reaction forms a compact, flexible and resistant resin. The final products push through the porous material into the base without any further increase in volume. This forms a waterproof sheath of variable thickness surrounded by a foam matrix that permanently consolidates the surrounding rock or soil.
DrucHyd-2C is capable of hardening with or without water. With water it forms a stable, resistant and hard yet flexible foam while without water a hard yet flexible non-foam material is formed which is characterized by high chemical and mechanical stability. The hardening/foaming reaction takes place at a relatively fast pace. Nevertheless, for specific applications or in cases of low temperatures (below 15°C), the reaction can be further accelerated by adding small quantities (0.5-1.5 % in weight) of a specific accelerant to one of the components.
