Earth Retention System
We plan and construct excavation pits considering side conditions. According to the requirements we execute slope protection, contiguous pile walls, Secant Piles wall , sheet pile, bored pile etc .. Necessary retaining systems such as anchors or struts.
Additionally dewatering measures and the execution of all earth works is part of our range of services.
Contiguous Pile Wall
A spaced pile wall system is built with a series of bored piles – with center-to-center spacings not exceeding the diameter of three piles.
The stability of the piles is ensured either by the self strength of the piles or by using rows of internal bracing or prestressed anchors. Steel reinforcement is used in every pile and consists of either a steel cage or steel profiles.
Secant Pile Walls
Secant Pile Walls are interlocking cast in-situ bored piles forming a continuous wall by drilling under mud .The system is generally used in water-bearing soils, utilizing primary non-reinforced piles and secondary reinforced piles. Pile overlap is typically in the order of 10 cm).
Soil Nail Walls
Soil nail walls consists of installing passive reinforcement (i.e., no post-tensioning) in existing ground by installing closely spaced steel bars and placing a front face support. Soil nailing can be used to stabilize, deep excavations, slope faces, to stabilize existing slopes . Soil Nail walls are constructed from the top down and include several rows of passive inclusions with a shotcrete facing.Soil nail walls have very flexible shapes and can adapt to almost any geometry.
Shotcrete
shotcrete is used to support the soils between spaced piles – or on nail walls – and can be smoothened to facilitate the application of waterproofing membranes.
Foundation Works
Bored Piles
Bored piles are cylindrical bodies made of concrete (with or without reinforcement) which are installed in the ground by a variety of methods. They transmit high structural loads into lower, load-bearing soils.
CFA Piles
CFA piles are constructed by rotating a hollow stem continuous flight auger into the soil to a designed depth. Concrete or grout is pumped through the hollow stem, maintaining static head pressure, to fill the cylindrical cavity created as the auger is slowly removed.
Steel Sheet Piles
Steel sheet piles offer a comprehensive range of services that contribute to their indispensable role in various construction projects. These resilient steel components provide effective solutions for multiple applications, highlighting their versatility and adaptability.
Driven Piles
Driven piles are structural elements used in foundation construction to support buildings, bridges, and other structures. They are installed by driving them into the ground using impact hammers or vibratory drivers until they reach the desired depth or resistance. Common materials for driven piles include steel, concrete, and timber, each offering unique advantages depending on the soil conditions and structural requirements. Driven piles are favored for their simplicity, speed of installation, and suitability for a wide range of soil types, making them a popular choice in construction projects worldwide.
Water Well
Water well construction involves the process of drilling into the earth's surface to access groundwater reservoirs. Specialized drilling equipment, such as drilling rigs, is used to bore into the ground to reach the aquifer layers that contain water. The well is then lined with casing to prevent collapse and contamination of the water source. Once the drilling is complete, a pump system is installed to draw water from the well to the surface for various uses, including drinking water, irrigation, and industrial purposes. Proper construction techniques are essential to ensure the efficiency, safety, and longevity of the water well, providing a reliable source of freshwater for communities and industries.
Excavations
Excavation is a foundational process in various industries, involving the careful removal of earth, rock, or other materials from the ground. From laying the groundwork for construction projects to uncovering archaeological treasures, excavation plays a vital role in shaping our world.
Dewatering
Dewatering services are crucial for managing water accumulation in construction, mining, and environmental projects. By controlling groundwater levels, these services ensure site stability, safety, and operational efficiency. With specialized equipment and expertise, dewatering solutions provide reliable water management solutions for various industries, facilitating construction progress, preventing flooding in mines, and mitigating environmental contamination.
