This is a Pennsylvania slate stamped concrete driveway/sidewalk. No colour added. This is an expansion foam embedded at the weak point of the corner of the house. Expansion foam is a very important part of a concrete installation. The expansion foam allows for the concrete to move of break in this area, other wise know as a "control joint". Let us know if you would like to view this driveway.
