ARC is an expert paver and pedastal system contractor serving San Francisco, Marin county, and the greater Bay Area.

A leaking second story courtyard above a condominium living area requires the topping slab to be removed to access a failed waterproofing membrane. It will be replaced with a CIM waterproofing membrane and, instead of tile or concrete, a paver system will be installed for ease of detection and repair of any future leakage.
