Precast Cantilever Wall

Cantilever wall systems are typically large “L type units with” an extended footing on the front side of the wall. The footing helps resist the overturning moment. Cantilever wall systems retain the soil by virtue of their size and weight. No additional reinforcement of the soil is required.

LHV Precast can custom manufacture high quality cantilever retaining walls that are precast using reinforced concrete. They consist of a relatively thin stem and abase slab. The base is also divided into two parts, theheel and toe. The heel is the part of the base under the backfill. The toe is the other part of the base.


  • Use less concrete than monolithic gravity walls
  • Generally economical up to about 25 ft. in height.
  • Wet cast concrete product allowing for customization


  • Require careful construction and engineering
