MICROPILES
MICROPILE FOUNDATION SOLUTIONS
At EGF (Emirates German Foundation), we provide reliable Micropile foundation solutions for projects that require deep foundation support in restricted, challenging, or sensitive site conditions. Micropiles are small-diameter foundation elements, typically 300mm or less, installed using compact drilling rigs suitable for limited-access areas.
Micropiles are drilled using fully cased methods with segmental drill pipes until the required design depth is reached. Once drilling is completed, high-strength steel reinforcement bars are inserted into the grouted borehole. The segmental casings are then carefully removed, allowing the grout and reinforcement to form a strong structural foundation element.
Micropiles are especially useful where larger pile systems are not suitable. They are commonly used in ground conditions containing large boulders, areas close to existing structures, low-headroom spaces, and sites with complex or karstic geology. They are also effective for strengthening existing foundations, replacing deteriorated foundation elements, supporting slopes and embankments, and improving overall soil stability.With technical expertise and specialised equipment, EGF delivers micropile solutions that are safe, accurate, and suitable for complex foundation requirements, particularly where space, access, vibration, or ground conditions limit the use of conventional piling methods.Restricted Access / Low Headroom Micropiles
Low headroom micropiles are installed using the same basic technique as standard micropiles, but with compact electrically powered drilling units designed to operate in areas with very limited vertical clearance. This makes them ideal for basements, existing buildings, industrial facilities, underpasses, and other restricted-access environments.
EGF’s low-headroom micropile solutions are suitable for underpinning, foundation strengthening, and structural support works where traditional piling equipment cannot be used. This method allows foundation works to be carried out safely and efficiently while minimising disturbance to surrounding structures.
