What does our commercial asphalt paving and repair entail? Berry’s asphalt paving base work and top coating includes grading, leveling, prep for drainage, and laying down the base (#57 stone). If the existing lot material is soft underneath, we will need to put down a silt paving cloth. Unsure of how much material you will need for the job?
