From TMP, I do not think these are on the Urban Construct site yet though for sale, cant seem to find it. Looks decent for really shelled out landscapes

Urban Construct have released a new Battle Tile.
Representing a ruined street scene with shell holes, ruined walls, and torn road surface, this tile can be used for WWII, modern and post-apocalypse.
Designed to complement our modular buildings, roads and sewers to form a 3D battlefield, the shell hole bases can be knocked through to get access to basements or sewers.
A limited number of discounted-price, painted resin models will be available for purchase at Salute 2011, stand TA23, far left-hand corner.
If you are into 25/28mm skirmish, then our website and stand are worth a visit.
