Replacement piles are made inside a Earlier drilled borehole, Therefore restoring the unearthed ground.
The grouting with the group A micropiles is ready under gravity. In team B, grout is injected under บริษัทรับตอกเสาเข็ม pressure into the outlet, nevertheless the pressure is constrained to prevent hydrofracturing on the nearby soil. Group C micropiles are installed in two actions: very first, a Most important grout is force-applied to hydrofracture the bordering รับตอกเสาเข็มไมโครไพล์ นนทบุรี floor, after which you can, just ahead of the primary grout sets, a secondary grout is injected via a manchette tube.
