Soil anchors

Soil anchors are mainly used for supporting retaining walls and steep slopes.

The anchors are driven using impact drilling methods where the rods are equipped with a drill bit and injection channel (Ischebeck, Belloli, Minova MAI, InfraLock etc.). Through consistent adding of cement and water the rods are driven to the required depth.

The cement water solution creates a concrete body around the rod which increases the pile’s side friction and load-bearing capacity. The concrete body protects the rod from corrosion and depending on the protective layer’s thickness may give the anchor a 120 year lifespan. We drive soil anchors with diameters between 30-130 mm.

Soil anchor design is considered in the following standards:

EVS-EN 1997-1:2005+NA:2006
"Eurocode 7: Geotechnical design
Part 1: General Rules";
EVS-EN 1997-2:2007+NA:2008
"Eurocode 7: Geotechnical design
Part 2: Soil analysis and testing"

Work is executed according to the following standards:

EVS-EN 1537:2013 "Execution of special geotechnical work - Ground Anchors";
EVS-EN 14490:2010 "Execution of special geotechnical works - Soil nailing".
