The grout/floor bond strength realized is affected mainly by the ground variety and grouting strategy applied, i.e., tension grouting or gravity feed. The role in the drilling process is also influential, Whilst much less effectively quantified.
When working with complicated soil conditions or retrofitting existing structures, micropiles supply a versatile and highly efficient deep foundation Answer.
