Making a low embankment

Armed with a small tub of Agnew's Water Putty [US equivalent is Durham's] I decided it was time to do something about it.
The putty was mixed to a reasonably stiff consistency - not at all sloppy, but soft enough to be workable while being stiff enough to be able to be piled up without collapsing.
I spread it along the bend using a flat stirrer to push the putty out of the pot as I went.
The manufacturer suggests smoothing with a damp sponge. I used a small piece of cork tile dipped in water:
The putty was stiff enough to hold the gentle slope that I was after
While the putty was still wet I sprinkled on lots of beach sand and some coarse ballast. This was pushed into the surface and I used a 1.5inch wide roll of tape as a steam roller.
Time will tell if the sand and ballast hold well, but it can always be glued down like normal ballast.
All I want here is a slightly rubbly slope overgrown with grasses and weedy plants. It won't be spectacular - just everyday stuff.
The putty has about 30 mins working time, depending on your mixing ratio. Paint can be added to it but I've found it speeds up the drying time alarmingly! This job took less than 30 minutes.
I'll check this area later to see how it's holding up. When it's dry I can see about painting it a bit and adding the first grasses etc.

That looks pretty good Mike, it has a 'natural' look to it :thumbs

This is the first time I've used it for something as extensive. The embankment is close to 20" long. In the past I've used it to fill in some hollows and I've made a short length of road as well as the level crossing.
I just went and checked it. It has set nicely and most of the sand and ballast is well attached.
The good thing about the water putty is it sets as hard as a rock, making it less likely to chip than plaster. I have used clay for this job too but it tends to shrink a bit and it can crack. From my limited experience I'm thinking the putty does the best job.

I can't extend it any further yet because I have to put in a level crossing and a major road at one end [the closest bit in the last photo]

I wanted to work some little gullies into it to suggest water runoff, but the putty had almost set before I got around to it. So today I've hacked a few into it with a chisel. Just little ones - nothing major. More pics will follow sometime soon.

While working with the chisel I accidentally broke some of it away. Some of the pieces have been recycled as rocks. More ballast and sand was glued on too. I'm hoping the putty itself will look like soil.
Everything is glued down. Next step is to paint it.
I have some drain grilles here somewhere. I might make a concrete drain and install a couple.

Acrylics used: matt white undercoat [sample pot from hardware store]
black
raw umber
red oxide
mild blue called "cobalt blue hue" by Reeves [ I wouldn't call it that!]
skin tone base - which is more of a sick yellow
I started with the darks, mixing black and raw umber together. I then swept a waterlogged brush over all of the bank, then painted a very runny dark into any hollow, adding another drop of water if it didn't run enough. It fills in all the nooks and crannies.
Next I mixed up some soily colours using black, raw umber, red oxide, blue and some white to get loads of variety in the colour:
It needed a fair bit of treatment to hide the yellow of the water putty, although I quite like that colour showing through here and there.
After that I needed to redo the darks a bit:
This one shows the variety of colours in the ground. I found the blue and the red oxide particularly useful and interesting:
It also shows where I've started picking out some of the raised forms with a bit of yellow mixed into some of the paler colours. Basically the lighter bits are white+any old soil colour+yellow. I made some of the lights a bit bluer too.
Highlights and lighter colours were applied quite dry with the brush held parallel to the ground. I think it's important that they aren't overdone. Just a small percentage of light looks better. 15%, maybe.
Grasses and other bare plants to be added yet.Any dodgy bits can be hidden [in my case] with snow. Good old snow :thumbs

P.S. some individual rocks were picked out with a tiny brush. Any old light colour that was lying around, as long as it wasn't too white.
