CarboCrackSeal NV H and U Resins

The resin has excellent adhesion to dry and wet concrete surfaces. In case of water intrusions which can not initially be stopped with CarboCrackSeal NV, the fast foaming SPUR injection resin CarboStop U can be used to stop the water flow.

Details
Carbofill®

Instant foaming two component phenolic resin system for the filling of cavities in underground roadways and longwalls for stabilisation and the prevention of gas accumulation.

 

Details
Carbopur Family

Carbopur is a dual-component injection resin for permanent sealing and consolidation in waterbearing strata.

Details
Carbothix Resin Anchoring Grout

Carbothix™ is an instantly thickening fast curing two component silicate resin for high strength bonding of solid bolts and cable anchors.

Details
Celbex 653

Celbex 653 is ideal for stabilizing cement grouts and cement grout blends, for pumping into cavities or fissures subject to water flow, or for pumping wherever grout has to remain in position without form work. Typical uses include grouting secondary tunnel cavities and grouting fissures and cavities of all types, including granular fill and instances when “stop and stay” grouting is required.

Details
Celroc P Non-Shrink High-Strength Hydraulic Cement

Non-shrink, high-strength, rapid-hardening, low w/s ratio, hydraulic cement typically used for anchorages and small void fills.

Details
Durafoam

Durafoam is a high yield, single component mineral and cement-based binder. After blending with the appropriate amount of water and foaming in a suitable machine, it sets to become a durable foam.

Details
Ekobet PT

Ekobet PT is a rapid-setting hydraulic cement. It is a one- component material which when mixed at the site of application with the appropriate amount of water (water/powder ratio of 1:1) sets to become a durable concrete material.

The material, upon exiting the pump, is liquid and thus it is able to fill any roughness and gaps. Ekobet PT gels after about 3 minutes depending on the preparation method.

Details
Ekoflex

Ekoflex is used for fire and methane hazard prevention by filling voids, sealing mined-out openings & walkways. It can also be used to build or seal insulation and ventilation dams.

Details
Geoflex Bonding Resin

High performance non-foaming silicate resin for high strength bonding and stabilization.

Details
Geoflex High Strength Bonding Resin

High performance, rapid-curing, non-foaming silicate resin for high strength bonding and stabilization

Details
Geofoam Rapid Expanding Silicate Resin Foam

Rapidly reacting and strongly expanding two component urea silicate resin system for immediate stabilisation via strata injection or cavity filling applications.

Details
Sprayed Cement Systems

Minova manufactures and supplies an extensive range of sprayed coating and sealing systems for use in a large range of applications in mining and civil engineering, including a range of dry bagged shotcretes and specially developed plaster.

Details
Tekfoam

Tekfoam cement is a foamed mix for use in cavity filling and back filling. Although the primary use for Tekfoam cement is the filling of cavities on longwall sections, other popular uses include back filling over a set of arches to provide contact against the roof, filling a cavity to prevent methane buildup, and cushioning against falling debris over false roof.

Details
Teknite

Teknite is a high strength cement coating ideal for quickly coating an entryway with a strong durable sealant. Uses include the prevention of spalling from moisture ingress and helping ensure the structural integrity of mine passages. It is an excellent alternative to gunite or shotcrete without the mess.

Details
Tekseal HD High Strength Void Filler

Tekseal HD is used for void filling where very rapid development of strength is required.

Details
Tekseal®

The Tekseal® pumpable seal process is a revolutionary system for installing permanent underground ventilation seals.

Details
Tektrench

Tektrench is a two-component pumpable self-foaming product used to slow or stop the water ingress around pipelines in trenches used by the gas, oil and utility industries.

Details
WilkitFoam T

Rapidly reacting, strongly expanding foam filler, suitable for spray-on application, CFC-free

This resin is designed for

  • rapid filling of cavities

  • consolidation and sealing in strata and soil

  • stopping of water intrusions

  • stabilisation of cavities caused by rock falls in tunnelling

    Applicable at ambient temperatures between 10 °C and 40 °C.
    At an product temperature < 10 °C it can become to flocculations.

    WilkitFoam T is resistant against water, diluted acids and alkaline brines. It does not absorb water. WilkitFoam T does not affect groundwater quality.

Details

Cavity and Backfilling

Products for cavity filling include cement foams or a range of pumpable resin foams.

Products for backfill include both tabular stopes and large excavations.

Conbex Backfill Cementitious Binder

Conbex Backfill is a blend of cementitious powders that act as a binder for milled mine tailings used in back-filling.

Details
Durafoam

Durafoam is a high yield, single component mineral and cement-based binder. After blending with the appropriate amount of water and foaming in a suitable machine, it sets to become a durable foam.

Details
Fillset Additive System for Cemented Backfill

The Fillset system can be used to produce a stiff cemented backfill, the characteristics of which can be designed to suit specific backfilling requirements.

The Fillset system consists of two components,  a powder, Fillcem and a liquid, Fillgel. When added to tailings slurry, the components react in time to form a homogeneous hardened backfill. 

Fillcem is a blend of specially selected powders proportioned to give a long pipe life and optimum strength development in the backfill. 

Fillgel is an inorganic liquid additive, which when added to the slurry reacts rapidly with the components of Fillcem to accelerate solidification with minimal water loss.
