Parking Lot After

Here is a fresh stain from a vehicle leak in a parking lot. An oil spill that is left on concrete will begin to weaken the concrete and seep down into the pores. This stain was treated only once, it was done on a Friday and by Monday it looked great. The oil has been lifted from the concrete and now looks as if the stain was never there.
