Cased micropiles are a specialized type of foundation system designed to provide a reliable and cost-effective solution for deep foundations. Unlike standard micropiles, which consist of a steel bar grouted into a small-diameter hole, cased solutions utilize a high-strength steel casing.
The construction process begins with drilling a small-diameter hole into the ground. Once the desired depth is reached, a steel casing of similar small diameter is inserted and left in place. Steel reinforcement is then inserted into the casing and grouted, creating a robust and stable foundation element.
Micropiles find their niche in diverse applications. Whether you need support for wind turbines, towers, transmission lines, or residential and commercial buildings, our skilled engineers can tailor micropile solutions to your specific needs. We specialize in:
Commonly used to provide reliable foundation support in both new construction and retrofitting projects. They are capable of transferring heavy loads from structures to the underlying soil or rock strata. Can be utilized to support a variety of structures, including buildings, bridges, towers, and industrial facilities.
Highly effective in stabilizing slopes and preventing soil erosion. By installing them at various angles and depths, they reinforce the slopes and enhance their stability. They play a crucial role in preventing landslides and maintaining the integrity of embankments, hillsides, and cut slopes.
Often employed for underpinning existing structures that require additional support or foundation reinforcement. Their installation can be carried out in limited access areas or in close proximity to existing structures without causing significant disruption. They provide a reliable solution for strengthening foundations and improving the load-bearing capacity of buildings.
A cost-effective and efficient solution for constructing stable retaining walls. They can be installed vertically or at an angle to support the weight of retained soil and resist lateral forces. Offer stability and durability, making them an ideal choice for the construction of retaining walls.
Commonly used in bridge and infrastructure projects, especially in challenging soil conditions. They provide reliable foundation support and can be installed in areas with limited access or where deep foundations are required. They ensure the safe transfer of heavy loads from bridges, viaducts, and other infrastructure elements to the underlying soil or rock strata.
Play a crucial role in environmental remediation projects. They provide stabilization and support for contaminated soil or groundwater treatment systems. Can be installed to create barriers or containment structures, preventing the spread of contaminants and ensuring the safety of the surrounding environment.
Micropiling technology has evolved significantly since its inception in the 1950s. Introduced by Dr. Fernando Lizzi and Fondedile, micropiles were initially used for underpinning historic buildings. Over time, micropiling spread to the United Kingdom in 1962 and gained popularity in Germany. In 1973, it made its way to North America, but adoption was initially slow due to different market conditions.
In the mid-1980s, micropiling started to gain traction in North America, particularly among geotechnical contractors. The advantages of micropiles, such as load transfer capabilities and versatility in different soil conditions, became recognized. Advancements in drilling techniques, equipment, and materials have further improved the efficiency and effectiveness of micropiling.
Today, ongoing research and development efforts focus on enhancing the performance, sustainability, and cost-effectiveness of micropiling technology. Innovations in materials and drilling techniques continue to push the boundaries of load-bearing capacity and versatility that they can achieve.
