Boring,Rebar Nailing and Motorised High Pressure Grouting Work.Soil nailing is an innovation technology suitable for both cut and fills landscape.These are nothing but micro piles (lesser diameter piles).This method consists of drilling borehole using suitable drilling machine, which is capable of drilling inside hard rock.Rebar is inserted inside the bore hole and grouted with cement slurry.This grouted rebar is called "NAIL". Its purely depend on skin friction and adhesion with natural soil and rock .Its structural capacity is nothing but the pull out capacity of each nail.
Boring, Rebar Fixing in to the Rock Below and Motorised high Pressure Grouting Work. Anchoring is done to mobilize shear strength and offer the passive resistance of the soil. Anchor can provide the required resistance to the earth pressure acting on the structure.Ground anchors are also provided to resist the tensile forces exist.
(A) BY MANUAL REPAIR : Chipping and exposing the rebar, removing corrosion and salt present and treating the rebars and introducing additional rebar for the loss of steel quantity by welding and covered with polymer modified cement concrete and finished with polymer modified cement mortar.
(B) BY GUNITING/SHOT CRETING : Chipping and exposing the rebar,removing the corrosion and salt present and treating the rebars and introducing additional rebar for the loss of steel quantity by welding and covered with high pressure guniting/shotcrete method with polymer modified concrete /mortar. and finished with polymer modified cement Plaster.
Pressure grouting can be very effectively used in making the concrete of permeable nature to impermeable. The grouting can be done with cement slurry,cement with polymer slurry, epoxy and polyurethane based on site condition and requirement. Pressure pump of 40psi to 5hp motorised pump shall be used based on site condition and requirement.
