Reinforcing and confining an earth formation is effected by restraining units having retaining limbs for insertion into prepared holes in the formation and transverse portions for lying against the formation. The retaining limbs are inserted into the prepared holes and the transverse portions of the units are thus arranged to define a mesh-like arrangement anchored at least partially by the retaining limbs. The end regions of the transverse portions are anchored to and linked together to hold the transverse portions against the earth formation. The units normally have at least two retaining limbs and these limbs are forced into the holes to a depth of between about 0.5 and 2 meters. Formations may be provided in the limbs to inhibit removal of the limbs.
