Cast-In-Place Retaining Wall

Extreme Structures’ in-situ retaining walls are built on-site with removable formwork and constructed with reinforced concrete. The retaining walls are designed by a qualified, structural engineer to ensure there are adequate footing and enough steel to resist the lateral pressure of sloping soil. This type of wall can be used for landscaping, residential and commercial application to help hold back unstable embankments.
