Sure – the C channel is used for the start and finish of the wall (and for creating corners), and the I beam is used for the continuation of the sleeper wall (i.e., it connects each sleeper bay).
I Beams can also be known as H Beams, UB (Universal Beams), or joiners, among other names.
C channels can also be known as end pieces, PFC, U-piece, etc.
Our sleepers come in 2m and 2.4m lengths, 200mm high, and are available in a range of thicknesses to accommodate different wall heights.
We also manufacture 2m and 2.4m Cribs (100mm high) for each of our sleeper designs.
Please review the information on each of our product pages or contact us for more details.
You can build retaining walls up to 4m high using our engineered sleepers (subject to council approval and engineering).
No – UFPs are not engineered and designed to retain heavy compaction.
A light backfill (i.e., garden soil or bark) is acceptable; however, if paving and concrete will be against the UFP, then sleepers should be used instead. Please see the UFP page for more info.
UFPs’ primary function is to fill the gap underneath a fence, prolong the life of the fence panel by preventing it from rusting and provide extra privacy.
The general rule, unless otherwise stated by an engineer, is that whatever is out of the ground must be in the ground.
For example, an 800mm high wall must have 800mm of steel in the ground as well. Therefore, the steel length should be 1600mm.
It is recommended that you always go a minimum of 600mm into the ground.
