4.     METHOD OF STABILIZING THE BOREHOLES





               •    Casings should be provided as soon as boring works are carried out.

               •    Boring without casing is only permitted if there is no collapse in the hole.


               •    Other methods of stabilizing the boreholes:


                    •   Bentonite Slurry

                    •   Drill Mud


                    •   Polymer


               • The choice of stabilization method depends on factors such as soil

                   type, project requirements, and site-specific conditions.
