Our company is the oldest and most experienced waterproofing and restoration contractor in the US. We have revitalized aging structures located in dozens of states across the country. Our projects range from below-grade waterproofing of a 600,000 square foot auto assembly plant, to weatherproofing a 32-story office tower, to the delicate cleaning and restoration of stone and terracotta on a 100-year old church. In addition to building restorations we offer new construction, concrete and parking structures.
