Decorative Concrete Railway Sleepers

Postby developer3d » Sun Jun 20, 2010 10:17 pm

Does anyone have any idea how they create those decorative concrete railway sleepers that you see in landscaping yards like this ?

Beyond the obvious - that they pour concrete into a mould I mean. How do you they replicate that pattern. It is on the face and the sides as well so I am assuming they have a mould made from some durable flexiable material like rubber that they "peel off" but that sounds too complicated for mass production.

Has anyone seen this process locally to know how to do it ?

i have to say considering i am in the process of doing a small job for a neighbour using 30 s/h wood sleepers who,ever made the ones you showed did a great job of faking it very realistic
The detail is exellent even down to the lumps knocked out of them and the enhanced woodgrain you get with weathering
My sugestion would be real sleepers were used with a slightly oversized mould and latex poured in around the sleeper when you break the mould down you peel the latex oil it up
and fill it again if those are rsj,s they are slotted into they are the first i have seen in thailand
its a common sight over here in the UK in landscaping and funnily enough builders yards create their sand/ballast storage areas the same way
one way of enhancing the grain in timber is sandblasting it so you could fake it to some extent using wood but you may well have problens parting the wood and concrete interesting concept though fake sleepers the real wood are anything from £20--£40 dependant on grade
1000-2000bht
i hate to think what they weigh the wooden ones are a two man lift
my comments may be wrong but never deliberately

A mate of mine and me stopped off at a garden place one day and asked how much the wooden sleepers were and we were standing on top of them......they were concrete but looked so real it was amazing.
