There are many different types of waterproofing materials
and processes, each designed for specific surfaces and/or applications.
Brick, natural and precast stone, concrete, EFIS, wood, or aluminum
surfaces can benefit from water protection. Whether it is caulking,
coatings or repellant applications, they are all designed primarily
for one purpose – to prevent water infiltration without acting
as a vapor barrier. Landmark has experienced trained professionals
who possess a keen understanding of the uses and applications of these
exterior cracks and seams is an important part of building maintenance.
It reduces entry of air, dirt, and moisture and contributes to lower
heating and cooling costs. Among the most important exterior areas
requiring attention are:
High quality masonry coatings allow for vapor permeation, allowing the masonry to respond naturally to vapor and salts. They are generally color fast, retard corrosion and biological growth and provide resistance to weathering. Elastomeric coatings are crack bridging. Coatings enhance the visual and aesthetic appearance of the structure. Most coatings are applied by brush or roller.
Water repellants provide a deep-penetrating treatment for most brick, natural stone, terra cotta, concrete, stucco, wood and cast stone surfaces. They are usually applied by spray, brush or roller. It is important that repellants allow for the treated surfaces to breath, not trapping moisture. These products afford long lasting protection against deterioration caused by water, salts, carbon, mold, mildew etc.
