Product Details
Minova’s CarboStop range brings proven control to challenging water and ground conditions underground. All variants are water‑reactive, one‑component PU resins used for pre‑injection, sealing and stabilisation under active inflow, including saltwater and high pressure. Reaction is triggered on contact with water and can be tuned with the dedicated ACC accelerator to match site conditions; after dosing, mixtures can be stored for up to 48 hours when kept moisture‑safe. CarboStop 42 delivers ultra‑low viscosity for deep penetration into ultra‑fine to very fine sands. CarboStop 102 offers low viscosity with high expansion to consolidate soils, seal leaks and fix anchors and bolts under water transit. CarboStop 402 is formulated for high flexibility and elasticity, ideal for sealing cracks, joints and honeycombing where movement is expected. Selected variants carry recognised approvals for injection works and, where specified, water‑contact applications.
