1800mm High Retaining walls Engineered for Structural Integrity

Limestone Retaining walls are a common type of gravity retaining walls are designed as mass gravity structures, where the weight of the limestone blocks retaining the backfill material in a stable manner. This particular retaining wall is designed for a surcharge of 5 kPa.


The certified structural engineering, drawings, details and construction specification for limestone wall is produced in accordance with the performance requirements of the National Construction Code and certified by a Chartered Professional Structural Engineer. This limestone retaining wall details is designed for sand sites in Adelaide, Canberra, Hobart, Melbourne, Perth and Sydney. It is important to confirm the development and building approval requirements with the local government authority.


Various other non-standard drawings (for example brick screen wall constructed on top of limestone retaining wall) can be produced to suit particular requirements.

This certified structural engineering drawing can be purchased online and in most cases you will received the signed structural engineering details within 24 hours. Each retaining wall application and site plan is specifically assessed by one of our engineers to ensure that existing structures will not be adversely affected. Our team will review and determine if the structural engineering documentation is suitable for the particular site conditions and we always endeavor to provide custom engineering solutions.


Technical Specification
