Our grouting solutions are used for anchoring, bolting, backfilling, crack and void filling and as ventillation seals and standing support.
Our extensive portfolio ranges from standard pumpable to high-performance rapid-setting and high-strength grouts.
Our anchoring products include materials suitable for both manual and mechanised bolt grouting technologies. Our cementitious products are supplied pre-blended and pre-packaged for your ease of use.
TekThix was developed to improve the productivity of ground support installations in underground mining and tunnelling applications. Using a two component cementitious grout enables loads to be taken up in minutes rather than the typical 24 hours for other conventional cementitious grout systems.
TekThix can be used with:
Minova proprietary HYG technology is incorporated in the formulation. By combining with a large quantity of water this permits just one 50 lb bag of TekStem to fill 40 ft of 3-1/2” diameter borehole or 24 ft of 4-1/2” diameter borehole.
TekFoam is a non-combustible, void-filling, structural cement foam. Supplied as a powder, the cement forms a low-density foam (0.25 to 0.35 sg) when combined with the proper amount of air and water in the specially designed Tekplacer unit.
TekFoam mix is typically pumped 400 feet (121.9m) through a 1” (25.4mm) diameter hose, farther through a larger diameter hose. The 20 psi (0.1379MPa) product begins to gel in minutes, forming a non-toxic, non-combustible product weighing approximately 540 lbs/ yd3 (320.4kg/ m3). Because of its rapid strength gain, the foam material is firm enough to walk on in 30 to 60 minutes.
TekGrout® is a single-component, variable strength cementitious injection grout designed as an alternative to polyurethane systems.
A wide flexibility with strengths and viscosities enables excellent strata penetration and gel times as low as 40 seconds. The material’s adhesive and interlocking characteristics collectively assure a solid bond.
Terracem grout is a one-component, ready-to-use injection cement. It is a sulfate-resisting very fine blended cement with an integral super- plasticizer, ground and classified to a low particle size grading (D98 less than 40 micron; D50 less than 7.5 micron).
Terracem injection cement is specifically designed to grout fine sands, consolidate foundations, seal off flowing water and establish grout curtains in dam construction and rehabilitation. Additional uses include grouting of tunnel and shaft linings, rehabilitation of existing tunnel structures, and waste site remediation.
It is designed specifically for anchoring bolts and dowels in concrete, rock, brick and masonry.
Anchortite resists oil, grease, fats, mild acids, and alkalies, fresh and salt water. Where exposure to a specific chemical is anticipated, consult Minova directly.
Anchortite is used for grouting high strength anchor bolts, starter bars in concrete and anchors in rock.
Suggested applications for Anchortite include:
Other important uses include controlling water inflow into shafts and tunnels during excavations, pre-grouting of TBM/EPBM tunnel headings, formation of impervious grout curtains to contain pollution by hazardous waste and cut-off walls into alluvial deposits at dam sites.
The Terracol System is a completely water soluble process consisting of two components:
The amount of Terracol Part B - hardener needed ranges from ~10:1 to 5:1 by weight depending on the desired gel time (ie. a 6.6:1 ratio results in an approximate 30 minute gel time at 70°F).
Terraset® grout is a low-viscosity, chemical grout system used for ground consolidation and stabilization of foundations and footings located on fine to medium sands. Other important uses include control of water inflow into shafts and tunnels during excavation, pre-grouting of TBM/EPBM tunnel headings, formation of impervious grout curtains to contain pollution by hazardous waste, and cut-off walls into alluvial deposits at dam sites.
The Terraset® System is a completely water soluble process consisting of two components:
On a volume basis, the amount of Terraset® Component B - hardener needs to range from 10% to 15% based on the sodium silicate concentration. The higher hardener concentration gives the most durable gels. Gel time of the mixed grout solution is approximately 12 minutes at 70°F. The resulting gels are homogeneous, dense and well structured.
Cylindrical bags, 27” or 30” diameter, are secured to the mine roof and are subsequently filled with a foamed cement.
The installation of the TekCrib system is accomplished by using the Minova TekPlacer unit, specially designed to combine the TekCrib powder with air and water, producing a cementitious foam.
The foam is typically pumped a distance of 1,000 ft., although much longer distances are possible, especially when pumping down surface boreholes. The mix begins to gel within minutes of discharge and cures to a final strength, ranging from approximately 400-800 psi.
TekPak P is a patented pumpable crib material having substantial benefits in terms of roof control, speed and ease of installation. TekPak P has a high early strength allowing the crib to resist bed separation and convergence. The fully cured strength is substantial with over 150 tons of load bearing capacity.
TekSet® is a single-component, cementitious grout designed as a fill for a bag placed between the top of a crib and the mine roof, or atop a specially designed post system. Depending on the water temperature, the material will set in approximately 10 to 15 minutes. The tedious routine of blocking and wedging supplemental roof support is replaced by a simpler, faster and more efficient means.
Celroc P is a high-strength, non-shrink, non-metallic grout consisting of rapid hardening hydraulic cement and super plasticizer. Designed to produce a pumpable grout at low w/c ratios with the unique features of being highly resistant to dilution in moving water and aggressive ground conditions.
RD10 is environmentally friendly and can be applied through either topical means or mixed in with the soil.
The control of dust, typically by the topical application of water, can be a costly and disruptive process – often effective for only a limited time period.
RD10 is a water soluble non-hazardous emulsion that is designed specifically for:
The application of RD10 is completed by adding a percentage of the product to the water being used to control dust. Any water source can be used as the water is simply a carrier for the RD10 agent. Depending on the application, various rates of RD10 can be used.
