CarboPur™

CarboPur™ is Minova’s polyurethane injection range for water stopping, curtain injection and ground consolidation in mining and tunnelling, effective even under hydrostatic pressure.

Product Benefits

Reliable sealing under hydrostatic pressure improves roadway safety and asset life
Curtain injection cuts off ingress around structures, protecting operations and crews
Dual foaming/unfoamed behaviour adapts to conditions, improving consolidation
Wet‑strata stabilisation keeps headings advance‑ready and reduces remedial rework
Rapid cavity filling and crack repair restore integrity and support faster restart

Sectors

Metal & Non-Metal Mining, Coal Mining, Infrastructure

Applications

Anchoring & Rock Bolting, Ground Consolidation & Stabilisation & Stabilisation, Cavity & Void Filling, Structural Repair, Heavy Water Ingress & Water Control, Sewer Repair

Product Details

CarboPur™ is Minova’s portfolio of polyurethane injection resins designed to stop water ingress, consolidate ground and protect critical underground structures across mining and tunnelling. Our range includes fast‑reacting, two‑component systems that foam in contact with water yet harden unfoamed when water is absent, giving you control in unpredictable conditions. CarboPur WF and WT seal against water under hydrostatic pressure from strata, dams and shaft walls, supporting safe, continuous operations in wet headings. CarboPur WS excels in curtain injection for tunnels, dams and shaft walls, delivering sealing, stabilisation and consolidation while repairing cracks and fissures. For strong water inflows, CarboPur WFA provides an extremely fast reaction to regain control quickly in construction pits, pipelines, shafts and tunnels. CarboPur WX supports stabilisation in wet or water‑bearing rock, seals tributaries and aids renovation of wet shafts, tunnels, sewers and brickwork. Thixotropic CarboPur WT also enables precise placement for repairs, including underwater pilings and diaphragm walls.

Product Features

CarboPur resins stop water ingress and stabilise ground

Fast-reacting two-component PU injection solutions

CarboPur WF, WS, WFA and WT are fast‑reacting two‑component polyurethane injection resins for rapid response underground

Foams in water; hardens unfoamed when water absent

Selected CarboPur resins foam on contact with water and harden unfoamed without it, aiding both sealing and structural consolidation

Seals hydrostatic pressure in rock and shaft walls

WF and WT are engineered for sealing against water under hydrostatic pressure from strata, dams and shaft walls

Curtain injection for tunnels, dams and shaft walls

WS enables curtain injection around structures to cut off water and stabilise surrounding ground

Stabilises wet strata; seals tributaries and leaks

WX supports stabilisation in wet or water‑bearing formations and seals water tributaries; ideal for wet shafts and tunnels
