Southern California Waterproofing Expertise Since 1989
Our Story
Built on Experience Since 1989
Kazemi Waterproofing has been waterproofing some of Southern California’s most distinctive properties for more than 35 years.
Founded in 1989 by Ron Kazemi, the company began with a simple observation: while managing construction projects, Ron saw a consistent need for waterproofing subcontractors who could deliver the level of technical knowledge, craftsmanship, and attention to detail that demanding projects required. After personally overseeing and completing waterproofing work on several projects, he established Kazemi Waterproofing.
Today, Kazemi Waterproofing is recognized throughout Southern California for its expertise in complex waterproofing and roofing applications. Our team works closely with general contractors, architects, consultants, developers, and property owners to develop and install waterproofing systems designed around the specific conditions of each project.

Our experience includes custom luxury residences, retail, hospitality, multifamily and community housing, and commercial construction. From below-grade waterproofing to roofing systems, balconies, planters, and other critical building-envelope assemblies, our focus is always the same: long-term performance, precise detailing, and exceptional workmanship.
That commitment has earned Kazemi Waterproofing a strong reputation within the construction industry and a long-standing portfolio of repeat clients. Our work has also received national recognition, including the 2014 Sika Sarnafil Project of the Year Award for the installation of a single-ply PVC roofing membrane system on a high-end custom home in Malibu.
