Retaining wall price guide – other considerations
Other considerations which will affect project pricing. These include site access, excavations, drainage, back fill 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.
