Hi,The whole of the railway was ballasted in 2023. The new 4 track station that I built this year meant that I had to ballast that side of the railway again. As always fresh ballast looks better without the moss and detritus that accumulates over time, even 2 years.
For ballast I use 'Tarmac Grano Dust' and was pleased to see it is still available from B & Q this year.
This time I used a sieve and running water to remove the fine component of the bag leaving the larger size of grit for the ballast. I spread out the ballast and levelled it before squirting a diluted mix of outdoor PVA to fix it.
The fine part of the bag is smaller than grains of sand and is like a thick paste, perhaps it helps to bond the mix to make a solid base. I used this paste to fill some cracks and voids in the concrete block track base and also in larger areas between the tracks.
The 2025 sieved ballasting looks much better, the stones are more prominent, than the non-sieved 2023 ballast and will be my method when I next re-ballast despite the extra work of sieving and the loss of material that ends up in the bucket.

I have used 10mm limestone chippings in handy packs from Wickes. It always looks good and keeps track firm - perhaps not to scale but hey, it's my railway!
