Retaining Walls

ALL OUR SLEEPERS ARE SUITABLE FOR USE IN STRUCTURAL RETAINING WALLS!

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 divid 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, the RetainIT retaining wall systems and any other suitable timber combination you can think of. We also specialise in retaining walls under fences.

Whether you are a DIY retaining wall builder looking for a cheap retaining wall, or a professional landscaper, builder or fencer we have all the timber and fasteners you require to get the job done at a great price.

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.

If you are unsure or require some more advice do not hesitate to contact our friendly team.
