Designing earth retaining stabilizing structures (ERSS) and shaft construction involves evaluating site conditions such as soil and rock conditions and groundwater levels, selecting an appropriate method such as sheet piles, soldier pile and lagging or diaphragm walls, calculating required dimensions and capacity, developing a detailed design plan, obtaining necessary permits and approvals, and monitoring construction progress.

Our soil investigation service includes site investigation, drilling boreholes, collecting and analyzing soil samples, and preparing a report with recommendations for infrastructure design. By assessing soil physical and chemical properties, we can identify potential issues and provide appropriate design and construction methods to ensure infrastructure safety and stability.

Our team of experts specializes in designing and installing ERSS that can resist lateral pressures from soil and water. From temporary excavation support systems to permanent retaining wall structure, with the use of sheet pile retaining structures that can be reused, we strive to provide eco-friendly alternatives for tunneling projects, preserving natural resources and reducing environmental impact.

Ground improvement methods such as jet grouting, compaction grouting, deep soil mixing and fissure grouting, to increase soil strength, stiffness and permeability. Grouting mainly serves to improve the water-tightness, strength and stability of the surrounding ground when it is used in a tunneling project.

We specialise in shaft construction, which involves creating a vertical passageway through the ground serving as the location at which all material enters and exits. They vary in size and depth, and their design and construction are key to the successful completion of any tunnelling project.

Microtunneling, a method involves excavating a tunnel underground and installing a pipe or conduit using Herrenknecht Tunnel Boring Machine (TBM) guided by a laser or VMT-guided system. Microtunneling is typically used in urban areas to replace traditional open-cut methods which resulting  space constraints or environmental concerns. It is a precise, efficient, and safer method of installing underground infrastructure with minimal disruption to the surrounding area.

We provide instrumentation and monitoring services that involve the installation of sensors and equipment to measure and analyze the behavior of structures and the surrounding soil or rock. This service is critical for ensuring the safety and longevity of infrastructure and can help prevent catastrophic failures and reduce maintenance costs.
