While in the decreased area in the steel casing, a dry cement blend is supplied. The drop hammer drives the dry cement mix as well as steel casing decreased and reduce until the specified depth is arrived at. The dry cement mix acts like a hammer head (driving plug) with the procedure to penetrate deep beneath ground.

Even so When the uplift is adequately big, the friction capacity of some pile foundation styles can speedily solve โครงถักหลังคาสำเร็จรูปหาดใหญ่ this Predicament in a more productive fashion.
