A diaphragm wall is a reinforced concrete wall that is made in-situ. The trench is prevented from collapsing during excavation, reinforcing and casting by the use of supporting bentonite slurry. The slurry forms a thick deposit (the cake) on the walls of the trench which balances the inward hydraulic forces and prevents water flow into the trench.

Hydroelectric Projects are most favoured and sought after projects in the Power Sector due to its environment friendly power generation, non receding availability of resources in abundance and supporting nature of peaking capacity. Hydroelectric Projects are predominantly associated with Under Ground Construction Works coupled with Geological surprises.

Soil nailing is an economical technique for stabilizing slopes and for constructing retaining walls from the top down. This ground reinforcement process uses steel tendons which are drilled and grouted into the soil to create a composite mass similar to a gravity wall.

Ground anchors consisting of cables or rods connected to a bearing plate are often used for the stabilization of steep slopes or slopes consisting of softer soils, as well as the enhancement of embankment or foundation soil capacity, or to prevent excessive erosion and landslides.

A rock bolt is a long anchor bolt, for stabilizing rock excavations, which may be tunnels or rock cuts. It transfers load from the unstable exterior, to the confined (and much stronger) interior of the rock mass.

Shotcrete is concrete (or sometimes mortar) conveyed through a hose and pneumatically projected at high velocity onto a surface, as a construction technique.

Rock anchor is a high strength steel tendon, fitted with a stressing anchorage at one end and a means permitting force transfer to the grout and rock on the other end. The rock anchor tendon is inserted into a prepared hole of suitable length and diameter, fixed to the rock and pre- stressed to a specified force.

Compaction grouting is a process that improves the bearing capacity of foundations and underlying soils by pumping a low-slump cement mixture into the soil, under pressure.

Permeation grouting is the process of injecting a grout suspension (e.g. cement slurry, silica gel, etc.) into a granular stratum to produce a solidified mass to carry increased load andor fill voids and fissures to control water flow.
