Geotechnical Solutions

With over two decades of experience, we have evolved into a fully-fledged geotechnical company, renowned for delivering solutions in Pipejacking, Directional Drilling, Lateral Support, Sheet Piling, and more.

Horizontal Directional Drilling

Our horizontal directional drilling (HDD) services offer a precise, environmentally friendly method for installing underground utilities without disturbing the surface. Ideal for water, gas, and telecommunications lines, HDD allows for efficient installations in sensitive areas, reducing impact and costs.

Culvert Jacking

Culvert jacking by our skilled contractors offers an effective method for installing underground pathways for water flow under roads, railways, or any other barriers. This trenchless technology minimizes surface disruption, ensuring a faster, more cost-effective solution for infrastructure development and maintenance.

Pipe Jacking

Pipe jacking, a key service we provide, utilizes advanced trenchless technology for the installation of underground pipes. This method is perfect for urban environments where excavation is not feasible, offering a less disruptive, efficient alternative for sewer, water, and utility installations.

Sprayed Concrete

Our sprayed concrete services offer a versatile and durable solution for a wide range of construction needs. From slope stabilization to tunnel linings, sprayed concrete (shotcrete) provides a quick, efficient application process, ensuring high-quality, long-lasting results for any project.


Our shoring services provide essential temporary support for structures during construction or renovation. From excavation sites to building renovations, our shoring solutions ensure safety, prevent collapses, and allow for seamless construction processes, regardless of the project scale.

Sheet Piling

Sheet piling provided by our experts offers an effective solution for earth retention and waterfront construction. Ideal for cofferdams, seawalls, and retaining walls, our sheet piling techniques ensure structural integrity, water tightness, and durability against environmental challenges.

Soil Nailing

Soil nailing is an innovative technique we utilize to enhance slope stability and provide earth retention. Ideal for steep slopes and retaining walls, soil nailing offers a cost-effective, efficient method for preventing soil movement and ensuring the safety of nearby structures.

Rockfall Protection

Our rockfall protection services are designed to mitigate the risks associated with rockfalls and landslides. From mesh systems to barriers and nets, we offer customized solutions to protect roads, railways, buildings, and lives from rockfall hazards, ensuring safety and peace of mind.


Our specialized grouting services enhance the strength and stability of foundations and soil. From permeation to compaction grouting, we tailor our approach to meet your project's specific needs, ensuring improved ground conditions, reduced permeability, and increased load-bearing capacities.


Our caisson installation services provide robust deep foundation solutions tailored for structures requiring solid support in challenging soil conditions. Ideal for bridges, towers, and large buildings, our caissons ensure long-term stability and are designed to withstand environmental stresses, offering a reliable foundation for your projects.
