1. Set a slab the plan shape of the road.
2. Using SEO set the slab road as the Target and the site as the operator. The operation set to INTERSECT. This will trim the slab to be just where it intersects the mesh and the top will mimic the mesh irregularities.
3. Now using SEO set the mesh as the target and the road/slab as the operator and subtract with upwards extrusion.
