Micropiles are applicable when there are problems with using conventional deep foundation systems like driven piles, drilled shafts or augercast piling. These problem conditions include natural or man-made obstructions, sensitive ground with adjacent structures, limited access spaces and karst geology.

Terramesh system is a gabion faced mesh soil reinforced system comprises of mesh gabions with adjoining mesh reinforcing panel that can be used to construct structures with either a stepped front face or near vertical facing. The Terramesh units with rectangular shaped cells for stone confinement are placed horizontally within the slope with backfill compacted […]
Installation of horizontal drain intercept underground water flow away from the slope, releases pore water pressure and reduces accumulation of underground water by means of insertion of perforated pipes into drilled holes.
Scaling work is a process which is done to remove potentially unstable and loose rocks on slope face to prevent occurrence of rockfalls. Rock scaling is used where loose rocks needs to be removed in a controlled manner to reduce the risk of rockfalls. It can be utilised as a stand alone solution but is […]
A method of reinforcing in situ soil using steel bars grouted into drilled holes with a facing element, usually in the form of reinforced gunite blanket, grid beam or individual concrete pads that server to integrate all the soil nail, thus forming the stabilising and retaining structure.
Stabilising and protection of slope surface by means of sprayed concrete or shotcrete usually applied over wire mesh anchored to the slope face while drainage holes and weep holes are installed to avoid formation of pressure build-up from groundwater. Spraying of surfaces prevents erosion and enhances slope stability.
