| 845567 | 2010-01-04 08:01:00 | Looking at building a low timber retaining wall from 200 x 50 Tongue and Groove H4 retaining timber. The question is though what does one do with regards to fixing the capping beam on ? Is it best to saw cut off the tongue on the top rail or is it better to use a router to gouge a groove on the underside of the capping beam (only 50mm deep mind you). Any ideas/advice most welcome, thanks |

| 845571 | 2010-01-04 08:38:00 | What are you using for capping, and are the posts/piles you've used to support the retaining wall flush with the top of the wall, or slightly lower? One thing to be aware of when cutting treated timber is that the chemicals used to preserve the timber doesn't always soak all the way through. Cutting off the tongue should be fine since it's so thin, but if you've cut fenceposts or piles, you should get some Metalex (I think that's what it's called) and retreat the cut end. |

Haven't built it yet. Was going to use some 150 x 50 as a capping, was planning on having the posts and rails flush at the top. |

| 845574 | 2010-01-04 18:16:00 | I have no idea but cant you flip the boards up the other way? You shouldn't as water will get "stuck" in the groove (rather than running off), decreasing the lifespan of the timber. |

My job used to be this kind of stuff, do what somebody suggests and make sue ti use metalex on all cuts. Are you laying the capping flat if so cut off the tongue and the groove or just buy 150x50 square edge |
