Piling Works refer to the installation of piles or supporting columns below ground level, to serve as a foundation or support for structures built above ground level. These piles or columns must thus have sufficient strength and durability to support the weight of structures built above ground level, and should remain stable over a long period of time as well as withstand environmental factors such as strong winds, minor earth tremors, soil movements, and underground water.
Earth Retaining Structural Works
Earth Retaining Structural Works are sometimes incorporated as part of piling works, as piling works involve the excavation of soil, and earth retaining walls prevent the surrounding soil from collapsing into the excavated area. Earth retaining walls are structures built on construction sites to retain soil, rock or other materials in a vertical condition.
Geotechnical Works involve geological modification and improvement of ground properties in terms of permeability, strength, capacity and density. Soil modifications and improvements play an essential role in the stability of foundations built below ground level, and this would affect the stability of structures built above ground level. There are two (2) types of geotechnical works, namely slope stabilisation and ground improvement works.
Slope Stabilisation Works
Slope stabilisation works refer to the modification and improvement of soil properties on a slope in order to ensure that these slopes are maintained in a stable condition. The slope stabilisation works which we undertake are as follows:
Ground Improvement Works
Ground improvement works are any form of modification and improvement works performed on the ground/foundation. At present, the ground improvement works we undertake include grouting.
