Of the Hilfiker systems, the Welded Wire Wall is the most economical and adaptable to a variety of site conditions. Welded wire mats are used to reinforce the soil, providing the tensile strength to make the compacted soil into a stable structure.

The face of the wall can either be designed as battered, vertical, or cantilever walls; left exposed, vegetated, or covered with a concrete skin or blown mortar (gunite).

Hilfiker was the first manufacturer to incorporate the wall face and soil reinforcing mechanism as one unit. The reinforcement mats "stand alone," and are ready to backfill once in place.  Unlike competitors' products, they require no extra external bracing or internal supports.
