More substantial capacities are achievable with large diameter micropiles. Micropiles can aid loads in compression and tension and achieve their load carrying capacity from the pores and skin friction created between the grout floor as well as the encompassing soils and rock.
You're awarded a job on an previous challenge worksite. The location has a handful of small-diameter driven metal pipe piles (12 inches or much less) with the longest pile becoming a hundred toes lengthy. The piles must be removed. What is among the most inexpensive way to do this?
