HARDAZ galvanised joiner post, 88 x 1100mm. It joins a straight run of timber sleeper retaining wall for 75mm sleepers at three sleepers high (about 600mm). A recessed channel seats each sleeper flush — no fasteners and little excavation. Pressed from 2.5mm galvanised steel, the wall is about one-third the thickness of a conventional timber-post wall and is suited to walls up to 1000mm high. The recess also takes up later timber movement and shrinkage.
Key Features
- Heavy duty galvanised steel for longer life
- No fastening or packing required
- Recessed channel for a flush, non-obtrusive finish
- DIY friendly
- Joins a straight run of retaining wall
- Suited to 75mm timber sleepers (HARDAZ 88mm profile)
Installation
- Check council requirements. For walls over 1m, or walls on a slope holding considerable weight, obtain an engineer’s report.
- Post height should be double the finished wall height, so about half the post is below ground.
- Clear the line, set a string line, and dig a channel so the bottom sleeper sits 100mm into the ground.
- Stand and concrete the first post plumb. Seat the bottom sleeper before placing the next post, then repeat.
- Use quick-set concrete, a shovel or post-hole digger, tape measure, string line and level.
