Details
Electric Drive Void Filling Pumps

An electric driven positive displacement worm pump and feeder unit. This pump is suitable for use with Minova's range of aerated cement products.

Details
FlexKnot Steel Mesh for Rock Fall Prevention

FlexKnot’s unique knot design firmly binds both wires yet allows small adjustment once the side load exceeds 750 lbs.  This innovative feature is superior to standard welded wire mesh, where wires fail and welded joints break concentrating the tension on the remaining wires and ultimately causing failure.

FR270 High-Strength Plastic Mesh

High-strength, flexible plastic mesh

Details
MK1 Pump

This pump is recommended where more than 20kg of grout is to be mixed at any one time. The pump is equipped with a measuring flask. Recommended maximum mix is 40kg of cable grout.

Details
MK2 Pump

Mixer features a water level mark at 4 litres. This is enough to mix 10kg of grout powder (one bag).

Details
MK3 Pump

Mixer features a water level mark at 4 and 8 litres. This pump is recommended for a 10kg or 20kg grout mixture.

Details
Osro Rock Fall Straps

Osro rod straps are used in mining and tunnelling to provide continuous strip support between rock bolts, inhibiting fall-outs between the bolts and helping to maintain the integrity of the rockmass. The rock bolts are installed through the Osro straps and tightened against the rock surface. The stiffness of the strap results in pre-loading of the rock, as well as transferring loads due to rock movement onto the bolts.

Details
Pre-Stress Combo 2000 Pump

The unique Minova Pre-Stress Combo 2000 Pumps compresses and air operated pre-stress pump combination.

Details
Rebar Rock Bolt

Minova’s Reinforcing Steel Bar (Rebar) is manufactured to critical tolerances and standards to meet the day-to-day needs of our mining customers.

Details
Resin Injectors

The resin injector is used to load resin capsules into roofbolt holes, and consists of a plunger within a hollow tube.

Details
Rock Bolt Parachutes

Parachutes are recommended when resin capsules are air-loaded into rock bolt holes. The parachute guides and protects the capsule while it travels at high speed through the loading tube into the hole, then holds the capsule up the hole until the bolt is inserted.

Details
SDA - Self Drilling Anchors

MAI SDA self-drilling anchors provide a unique bolting solution for unstable ground conditions such as sand, gravel, silt, clay and in soft to medium fractured rock formations. For projects facing such ground conditions, MAI SDA selfdrilling anchors should be considered as the most productive reinforcement solution.

Details
Tekseal HD High Strength Void Filler

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

Details
Tekseal HS High Strength Cement Foam

Tekseal HS and HS Fast are used for void filling where higher cement foam strength is required.

Details
Tekseal S High Penetration Sealant

Tekseal S is used for void filling where longer flow distances and good penetration of loose fallen rock are required.

Details
Tekseal Void Filling and Lightweight Barriers

Tekseal can be used for general void filling and the construction of lightweight barriers, bulkheads and stoppings. Typical applications of Tekseal are for void filling above closed-off arches in tunnel drives or after rockfalls. Lightweight barriers for ventilation control are also easily constructed using Tekseal.
