Small Diameter Drilling technique provides structural support under challenging ground conditions. This technique used to transfer the load to competent strata to control settlement. There are two typical techniques of Small Diameter Drilling like 1) Micropiles 2) Anchor.

The benefit of Small Diameter Drilling Technique 

• Increase load-carrying capacity. 
• Remediate settlement to underpin foundation.
• The soil together within the predicted shear zones to enhance mass stability of slopes by “stitching”.
• Structures to mitigate liquefaction i.e  (load transfer from quantifiable soils to competent strata).
• Seismic Retrofitting 
• Provide structural support to facilitate in limited headroom construction.
