SWEPCO Products for Walls
Except for structural shifting and the cracking and deterioration which directly results from it, most deterioration of brick, concrete and stone exterior walls is attributable to one or more of the following: moisture, heat, cold, infrared radiation, ultraviolet radiation, acid rain, atmospheric contaminates, wind, rain, hail, sleet, high humidity and fungi. Over time, these conditions cause a natural process of deterioration that manifests itself in different ways depending upon the type of wall surface.
In most cases, the process starts with moisture absorption and drying, expansion and contraction, and the formation of hairline cracks. These fine cracks, checking or crazing allow moisture to penetrate the wall system and start a cycle of accelerated deterioration. In colder climates cracking is even more critical because moisture which has penetrated surface cracks will freeze and expand. This causes new cracking and enlargement of old cracks.
Once in this condition, a wide range of other problems begin to develop which can seriously compromise the function of the wall. Some of these problems include mortar joint deterioration, spalling and scaling. When these types of problems manifest themselves, deterioration of masonry construction has become a serious issue that should be addressed quickly before total destruction occurs.
Mildew, staining from adjacent metal materials, mineral deposits and atmospheric contaminants also work to destroy the appearance of expensive masonry construction.
Other types of surfaces deteriorate as well. Metal walls rust, corrode and develop dried out, chalky, oxidized surfaces.
Glass walls and interior walls, get dirty and require cleaning.
Subgrade walls have moisture penetration problems and sometimes active water leaks from ground water.
All of these forms of deterioration require attention and SWEPCO Products provide a cost-effective, long term solution.
