Sheet piles

Engineered Earth Retention for Challenging Environments

Sheet piles are long, interlocking steel sections that are driven vertically into the ground to form a continuous barrier and provide robust solutions for earth retention, flood protection, and waterfront construction. Installed using vibratory or impact hammers, they create a tight seal that effectively retains soil or water. The interlocking edges allow the sheets to connect seamlessly, forming a rigid wall that resists lateral earth pressure. Sheet piles are often used for earth retention, flood protection, and excavation support, especially in environments with limited space or unstable soil conditions. Once installed, they provide immediate structural integrity and can be temporary or permanent depending on project needs.

At CNT Geotechnical, our sheet pile systems are engineered for maximum stability, corrosion resistance, and long-term performance, even in the most demanding soil and environmental conditions.

How it works

Impact driving

Vibrodriving

Impact driving is a versatile installation method, particularly effective in cohesive soils. The precisely engineered structural height of the hydraulic hammer allows for the installation of relatively long piles, even with shorter mast lengths.

During installation, measurement data is recorded to track key parameters, including pile depth, impact energy, hammer strike rate, and the total energy applied per element.

High-frequency vibrators are used for driving sheet piles, trench sheeting, or beams through vibratory pile driving. When constructing narrow walls, a steel beam is vibrated into the ground using a vibratory driver. As the beam advances, it forms a narrow slot, which is then filled with suspension material. A continuous wall is achieved by overlapping successive beam installations.
