Site Drainage and waterproofing: Several existing sub surface terra cotta pipes will be replaced with larger capacity HDPE piping and he existing waterproofing system (applied membrane and drainage mat) will remain, but it’s exposed and repaired in some locations, a French drain is to be installed at the base. Piping was ran along the perimeter of the house to capture the foundation drainage and the downspouts sub surface.
Mechanical System Upgrade: The basement of the mansion sis a split system that serves only this level, the two upper levels will be served by a new Direct-Expansion (DX) refrigerant cooling and heating system with side-stream dehumidification.
