Bradco Companies is a regional leader in the commercial waterproofing industry. Since its inception in 2001, Bradco has become the go to team in the Omaha area for many of the leading general contractors when their project requires waterproofing.
Waterproofing is the treatment of a structure’s surface to prevent the passage of water under hydro-static head or standing water conditions. It is used for foundation walls and sub‐structures, slabs‐on‐grade, plaza decks, planters and green roofs, sumps and elevator pits, and between slabs or split slabs.
The first step in selecting the most appropriate waterproofing system involves determining when and where it is to be employed on the building. In standard construction projects, positive‐side waterproofing is generally applied directly to the face of the structure exposed to water (or hydro-static head of water). Negative‐side waterproofing, on the other hand, is applied interior to the exposed structure, either in the wall or on the inside face of the wall—it has no direct exposure to ground water. Finally, blind‐side waterproofing is affixed to an adjacent structure or soil retention feature (e.g. slurry wall), rather than the new structural wall. It is ‘blind’ because one cannot see the finished product sandwiched between the wall and the neighboring property.
