Canopy Pipes

The installation of canopy pipes is an proven construction method used as a temporary or permanent support structure . Self drilling steel pipes are installed at the umbrella roof prior to ground excavation, increase the stability in the working
area by transferring loads in the longitudinal direction. System is compatible with modern drilling rigs.

GFRP Anchor Bolt

FRP rock bolts and FRP injection tubes with advanced strength and head load. It was developed for strata support in mining and tunneling as well as for slope and face stabilization. Due to continuous coarse thread profiles the bolts and tubes can be trimmed if needed. The products have a high ultimate load
and due to their profile they offer a maximum bondage with all grouting material.
The cutting ability prevents damage to machinery and equipment while drifting and enlarging tunnels.

Inflatable Seals

By inflating the tubular seals made from textile fabric with cementitous mortar, The product efficiently seals the annulus as for TBM launch and exist. Tailor made seals meet requirement of different diameter and section length.

SOFRASAR Segment Accessories

We provide a complete range of bespoke or standardised bolting systems, dowel systems, centring systems & shear dowels, grout-lift sockets, guiding rods & packers plus precast accessories & security systems.

We actively assist in designing precast concrete segment tunnels. This enables the continuous optimisation of project fastener, which enable cost savings with a defined fastener methodology.

SEALABLE Segment Gasket

The gaskets placed between lining segments in many TBM-bored tunnels are a vital component in ensuring a long and useful life for the tunnel by protecting the lining and the tunnel interior from ingress of groundwater, and other material, under pressure.

Major developments are anchored or cast-in gaskets, the use of hydrophilic material to swell on contact with moisture, and designs to resist higher pressures.

Micro Fine Cement

We meet highest requirement for MF cement with finest grade 6 micron D100. Water sealing and ground stabilization can be acheived with careful selection of MF cement.

Grout Packer

A complete technical solution for grout & injection accessories would be important for successful projects. Packer and connectors are made to suit different circumstance.

Injection Pump

We offer solution with versatile equipment working in confined space for injection of resin and mortar, meeting different requirement of flow and pressure.

Polyurthene Resin

PUR-O-STOP FS is a fast reacting, rigid, two-component injection resin based on polyurethane for water proofing and stabilisation of water bearing structures. The resin is used for stabilisation and solidification of water bearing rocks, ground, sand as well as for stopping in rushing water in tunnels, shafts, dams and other building structures, and as a concrete injection product for force transmitting filling of cracks.

Acrylate Resin

Very low viscosity acrylate resin, harden by polymerization which setting time is fully adjustable from 20 seconds to 45 minutes, The elastic gel deliver excellent result for sealing fine crack of concrete, and consolidation of fine soil. This is an efficient solution where space is limted and high pressure grout is not allowed.

Silicate Resin

FOAM SEAL PLUS is a two component, quickly reacting, slightly flexible, treated with flame retardants injection foam based on silicate. It is used for filling of cavities in tunneling, mining industry and civil engineering for solidification of rocks as well as for stopping of inrushing water.

IGNIS Polypropylene Fibres

Numerous Tunnels have been constructed with concrete containing Ignis fibre. Testing on structures now concludes that concrete containing polypropylene fibres will be a necessity to reduce in explosive spalling during fire.

EASYSHOT Synthetic Fibre for Shotcrete

Durus EasyShot is the result of research into developing fibres that comply with the requirements of specific applications and end-uses. For shotcrete, this polypropylene fibre is proven to achieve a high degree of energy absorption at low fibre dosages.

GERB Vibration Control System

We provide Vibration control system by means of steel spring, elastomer and tune mass damper, which is highly engineered solution for isolating building structure, railway track, machinery, and power plant.
