Home >> Soil nailing

Soil nailing is a construction technique that can be used as a remedial measure to treat unstable natural soil slopes or as a construction technique that allows the safe over-steepening of new or existing soil slopes, which is used to maintain or enhance the stability of the soil by installing reinforcing elements.

Soil nailing is an in-place reinforcement of the soil. It uses steel tendons grouted into drilled holes to create a stable block in front of the soil that requires support. Soil nails are used for the temporary support of excavations, construction of permanent retaining walls, construction or replacement of bridge abutments, and for the control of landslides.

The nail systems can be used as:

• Temporary nail:
Nail with a working life of up to 2 years
• Permanent nail:
Nail with a working life up to 50 years depending on the ground conditions and with sacrificial corrosion for the time-dependent corrosion behavior.

Sinodrills' self drilling anchors can be installed as soil nail, which performs drilling, anchoring and grouting in a single operation, no need to remove and insert casing tube, fastly save time and money.
