Inttratech Ground Reinforcement by Micropiles

Micropiles, also known as root piles, are deep foundation elements constructed using cement grout, high-strength, small-diameter threaded bars and/or steel casing. Micropiles are generally used when there are difficult ground conditions, such as natural or man-made obstructions, sensitive ground with adjacent structures, limited access or low headroom or karstic geology and strengthening old foundations.

Main advantages of micropiles are high load capacity in both tension and compression, easily socketing into hard rock and penetration through subsurface obstructions or boulders, minimal vibration and disturbance to adjacent structures in close proximity. The disadvantages of micropiles are the relatively high cost as compared to other piling systems and the buckling possibility in seismic loading when the soil has the potential of liquefaction.
