Until the mid-1990s, R. Brothers, Inc. was a dedicated painting company. When environmental standards for sealants changed, we found that the newly formulated, environmentally safer products were not adhering to many paint coatings. In response to this, we began waterproofing and caulking to protect the quality of our paint job. Since then, R. Brothers, Inc. has become an expert in all aspects of interior and exterior waterproofing. This includes sheet membrane applications, coatings, air barriers and all aspects of remedial waterproofing as well as waterproofing for foundations above and below grade. We can apply intumescent coatings for steel and wood surfaces. Our experience ranges from large-scale waterproofing of major commercial and high-density housing projects under construction to remedial waterproofing of historic buildings. We specialize in:
  • Epoxy Pressure Injection
  • Concrete Sealers
  • Deck Coatings
  • Fluid Applied Air Barriers
  • Vehicular Coatings
  • Caulking, Sealant, and Urethane Expansion Joint
  • Negative Side Waterproofing
  • Urethane Injection/Leak Repair
  • Air Barriers
