Guys

The 'up & coming' product (like, it's been around for quite a while) for outdoor G1 layouts is Hardie Backer board, used by the professionals when they build wet rooms, it's what appears to be a 'cement' based product, available in 4' x 2' x about 1/2" thick (12mm if i'm correct) sheets at about a tenner a go (if you shop carefully i.e. don't go to the big orange shed).

You can soak it, burn it, freeze it etc. etc, cutting is achieved by 'scribe & snap' or use a grinding disk if you want fancy shapes (anything other that a straight edge) - haven't used it myself (YET) but have seen it used in anger, I've visited one layout in the heart of the Derbyshire Dales (& accompanying rain/snow) & one within 100 metres of the North Sea coast in the North East (we should know how wet/salty & blowy & bl**dy cold that can be)  - when I get round to going outdoors it's number one on my list of 'layout' board (not even going to look at anything else).

Just my tuppenny worth & no connection with the product, apart from a satisfied observer & future customer.

Have used Hardie Backer board for years, after becoming fed-up with de-laminating so-called marine ply. Would thoroughly recommend it. (As used on Southurst Railway (NG) and Southurst Extension Railway-Gauge 3)

Hello Robert, and I trust all is still well with your railways on the weatherproof front?  Reason for asking is I’m thinking of using this material suspended over joists in the station area of my railway.  Can I also ask how you support your trackbeds and whether it copes with being stood upon?
Thanks, Tim

I was just googling this subject when your post came through Tim.  I would also like to ask Robert whether he uses 6mm or 12mm Hardie board - and I guess that will be relevant to Tim's question too.

Just seen this post. Don't know how I missed it. I have been happy with the 1/2 inch (12mm in Eurospeak) Hardie board for years, but recently I have noticed that board that has been out for well over 10 years, is just starting to delaminate in places, but is still perfectly usable.

I support the board on angle iron with fairly frequent cross-pieces, or on concrete lintels built up with parapets, again with fairly frequent crosspieces. 

If the crosspieces are more than a very few inches apart, I would not risk standing on it as it is quite brittle.

I still think that it is an effective weather-proof base for track.

Hope this is of some hope, but ask me if I you would like me to discuss in more detail.

Thanks Robert, good to hear it’s lasting well. 

I’m guessing Hardie board is the modern equivalent of the old fashioned cemented-asbestos corrugated roofing.

If my surveying has worked properly, and subsequent building work (!) then my station area of about 3’ wide should be pretty well level, so to avoid puddling on this cement board I’m thinking of drilling some drainage holes.  Support beneath might only be timbers about 18” apart, so I won’t plan on walking about on it except above the beams!

Once a trackwork is in place and satisfactory I would probably ballast the plastic GRS sleepers with a bird grit and cement mixture, which I guess would bond well.  Platform creation is a challenge for another day!

Regards,
Tim
