Retaining wall price guide – other considerations and costs

Most retaining wall projects will require other works relating to the retaining installation. Generally these will include excavations to prepare the area for the retaining wall works as well as a drainage zone behind the retaining wall. Pricing for these additional works will vary in accordance with the site requirements, access, excavations, drainage, backfill materials and project size.

Site access / site preparation 

Good site access is a major factor in the cost associated in the construction of retaining walls. 

Generally a mini excavator and other small earth moving equipment will be  required to prepare the area for installation of the retaining wall. This equipment  will generally be used throughout the retaining wall construction for site preparation, waste removal and installation of the drainage gravel. 

While manual labour can be utilized where machine access is limited, a much higher construction cost should be expected.

Retaining wall drainage / retaining wall back fill 

Durability should be the primary consideration for the construction of retaining walls. A well constructed retaining wall will stand the test of time.

Retaining walls need good drainage. This is usual slotted drain know as agg drain in conjunction with drainage gravel and geotextile fabric which is used to protect the drainage zone. Good drainage materials are also required, poor soils such as clay needs to be avoided.
