Pollen phenomenon in construction

<h2><strong>Introduction to the phenomenon of pollen ( salinization ) in construction </strong></h2><p>The phenomenon of substance appearing on the surface of brick walls , plastered walls or concrete surfaces white crystallization . What is it? What is it ? Is it worrying and how to deal with it? HPM Cemment Cement will help you answer your questions about this phenomenon in the article below .</p><p>White powdery substances deposited on the surface of the material are actually caused by dissolved mineral salts present in the material composition . Conditions for pollen to appear :</p><p>• The material contains dissolved mineral salts </p><p>• There is sufficient moisture to dissolve these salts </p><p>• The surface of the material is sufficiently porous so that these salt solutions escape to the surface </p><p>Mineral salts are found in materials (sand, stone, bricks, cement , water). When water enters the masonry (concrete, wall), the salts are dissolved and pushed out of the surface , leaving a white powdery residue . </p><p>Is it ominous ? The phenomenon of pollen on the surface is mainly affecting the aesthetics of the building . Even so, its presence indicates that the building is permeable , it is necessary to check to prevent the source of seepage to avoid damage later .</ p><p>There are 3 different cases of pollen depending on the severity :</p><p>• Pollen at an early age : excess concrete or mortar evaporates on the surface leaving dissolved mineral salts . In this case , after the curing material stops appearing , it only needs to be scrubbed and cleaned .</p><p> • Pollen at a late age: Because the building is absorbed by water from defects . Thus , pollen will appear as long as the problem has not been resolved . Remedies vary depending on the situation: repair construction works , waterproofing or drainage for foundations... </p><p>• In another case , pollen appears in very dry conditions : the water inside the material can evaporate before reaching the surface . That means that the Salt deposition occurs below the surface . Pollen can then cause the destruction of the material structure from the inside out due to the salt being swollen .</p><p>When you see chalk flowers appear, if they still recur after washing , it is necessary to take waterproofing measures for the project .</p> <p><strong>How to fix: </strong>use our specialized waterproofing cement such as HPM WATERSHIELD - CC30 WP and HPM WATERSHIELD - CC40 WP to completely overcome blooming </p>'
