A masonry building should let you enjoy Mother Nature while keeping her hazardous elements outside. In exterior masonry walls, the most common natural hazard is trapped moisture. Windblown rain or snow infiltrates through tiny fissures, or condensation forms where cool interior walls meet warm, humid outdoor air. If that moisture isn't expelled--constantly and dependably--it can lead to hazardous mold-growth, efflorescence, or wall-failure.

Mortar Net USA has won a series of U.S. patents for its line of remarkably effective--and surprisingly cost-effective--systems for preventing moisture buildup in exterior masonry walls. Marketed through some 300 distributors nationwide, these unique systems (for both brick & block) let moisture drain quickly to the outdoors, unimpeded by mortar-droppings or debris. Yet they're engineered for swift, labor-saving installation--even in restoration or remediation jobs.

For example, TotalFlash--the company's latest technological breakthrough, designed for cavity walls--contains multiple drainage components, ingeniously factory-assembled onto handy, 5-foot panels of flexible flashing. It delivers both redundant protections and exceptional coverage, yet lets builders gain savings of at least 50% in Time-&-Labor costs over conventional installations. (See the "TotalFlash Challenge" video on the company's website.) All the company's products reflect its sharp focus on superior performance and measurable value. As a result, the country's top builders have found there's no "or equal" for TotalFlash, Mortar Net, HouseNet, BlockNet or Blok-Flash.
