Micropiles are installed through a precise process that guarantees most load-bearing capacity and Basis balance. Here’s how it works:
The grouting with the team A micropiles is ready less than gravity. In team B, grout is injected stressed into the hole, though the tension is constrained to prevent hydrofracturing from the close by soil. Group C micropiles are put in in two techniques: to start with, a primary grout is pressure-applied to hydrofracture the surrounding floor, and then, just before the most important รับตอกเสาเข็มไมโครไพล์ นนทบุรี grout sets, a secondary grout is injected through a manchette tube.
