DIY Necromunda Mortalis floor tiles

So I made some tiles. Some pitted Mortalis tiles.  I'd wanted to expand my board, but not my debt, so I chose to use some of the out of the box Necromunda tiles into some filler ones for the battlefield.
With some Polyfilla and a bit of PVA mix and a press mould, I made some more flat surfaces for my terrain to sit on.

Those tiles seem to have come together nicely, and they were a simple space saving mechanism.

Although these were slightly different to the stock Mortalis tiles I normally use, they at least conveyed a continuance of the board, and also are fairly easily transportable.

Along with some unpainted bits.

Pressed (didn't use a great release mechanism)

This is the silicon mould that a friend made for me. 

Little bit of scratching to help the Polyfilla adhere.

All in all, a useful expansion to Mortalis! Will try and do this again soon, with a little better mixing and composition of the material to get a better finish.

Next up, new buildings!
