JB Engineering Micropiles are high performing, high capacity drilled deep foundation elements typically between 30mm-900mm in diameter that can extend to depths of 200 feet and achieve working loads of over 150 tons. Micropiles comprises of very strong steel casing, rebar and grout.
They transfer the structural load through improper soil layers to adaptable foundation soils. Commonly applied execution methods are drilling and driving with percussion or vibration, if necessary using ultra-compact equipment which permits working in tight spaces.
This means micropiles can also be installed within existing buildings. Micropiles are generally used when there are difficult ground conditions, such as natural or man-made obstructions, sensitive ground with adjacent structures, limited access/low headroom. They are commonly used to replace deteriorating foundation systems, for the renovation of structures, and to support structures affected by adjacent construction.
JB Engineering Jb welded wire mesh Gabions is manufactured from metal wires welded at their intersections. By using different diameter wires it can be made into a light or heavy gauge product. It is manufactured in mild steel, galvanized, and stainless steel.
This kind of deep foundation method includes small-diameter piles with diameters less than 15 inches. For the construction of micro piles, the ground is drilled using a temporary casing to stabilize the soil. After reaching the predetermined depth, the drill bit is removed, and the reinforcement and grout are placed inside the hole. Finally, the temporary casing is removed, and additional grout is injected. In some cases, a permanent steel casing can be used in combination with the steel reinforcing member to provide additional lateral as well as axial capacity. The piling process is illustrated below.
Micropiles can resist relatively significant axial loads and moderate lateral loads. To improve their lateral load deficiency, they can be installed at any angle. This installation causes low disturbance to adjacent structures. However, they are vulnerable to buckling due to their being slender, and this issue should be considered in the design. This piling method’s installation equipment is relatively small and can be mobilized in limited areas and low headroom conditions.
Among the major foundation alternatives Surface conditions factor is the leading to the selection of micropiles.
However, the cost of micropiles usually exceeds conventional piling systems and especially driven piles. Under certain combinations of circumstances, micro piles can be the cost-effective choice and sometimes the only feasible construction option.
