DrucPietra MI

rucPietra is an organic-mineral two components polyurethane grout which is low expandable and characterized by excellent chemical stability and mechanical strength. The product is ideal for waterproofing fractured rock, consolidation of loose land and rock, crack and cavity filling. Also designed for construction, lining and insulating materials, protection and water proofing of reservoirs and aqueducts, water conveyance in water-bearing stratum. Especially suitable for bonding injection drill bolts because the resins cure within just a few minutes and the bolt can be loaded in a very short time.
The irreversible reaction between the two components (A and B) of DrucPietra takes place very quickly (1-2 minutes at 25°C). For special or low temperature applications, it is possible to accelerate the reaction speed by adding ACCELERATOR K (1-2% by weight) to the component A.
The presence of water does not affect the reaction process and does not cause the product to swell.
DrucPietra is not flammable and hardens rapidly; it also has thixotropic properties that appear as soon as the two components are mixed. After hardening, the material retains some elasticity and adheres perfectly even to vitreous materials. It is not toxic and non-pollutant.
