Timber Retainer Walls

Retainer Walls & Fencing

A timber retaining wall not only gives a fantastic natural look and feel to your house and garden it is also the most cost effective way to retain or divide your yard.  There are many different types of retaining walls and as your Outdoor Timber Specialists we supply all types of timber for residential retaining walls to commercial retaining walls.
If you are looking to build a retaining wall we have you covered, from a small garden retaining wall, to sleeper retaining walls, round log retaining walls, wing split (half log) retaining walls, bevelled edge sleeper retaining wall, and any other suitable timber combination you can think of. We also specialize  in retaining walls under fences.

How to build a retaining wall?
It is important to remember to use posts and whalers that are strong enough to withstand the loads placed on your wall for the next 20 plus years… not just the next three.  This is an all too common mistake! Post spacings are recommended to be between 1.2m and 1.5m spacings. They must NOT exceed 1.5m.

Please check with your local council as to whether your wall needs to be engineered.

Below are some photos taken during construction of various retainer walls and fencing projects.

Building Approval and Certification

Local authorities generally do not require building approval or engineer certification for retaining walls up to 1 metre high. Walls (irrespective of height) closer than 1.5 metres to a building, and retaining walls greater than 1 metre high will generally require
building approval and certification by an engineer.

Back Filling and Drainage

Drainage shall be provided behind walls exceeding 400 mm high to prevent additional loads due to the build up of ground water.
A slotted polyethylene drainage pipe shall be provided at the base of the wall, discharging to a suitable outlet. To prevent backfill material from flowing through gaps in the wall and to assist in drainage, geotextile should be placed to the inside face of wales and between the drainage pipe and the backfill.
Backfill shall be a free flowing material such as ashes, sand or gravel – not clay.

Backfill shall be installed no sooner than three days after concreting posts.h
