Efflorescence is a very simple problem to prevent, but a difficult one to address once it has already formed. For those who are unfamiliar with efflorescence, it is simply a white powdery water-soluble salt which is left on the surface of bricks as water evaporates. For Efflorescence to occur, three crucial conditions must be met:<\/p>\n\n\n\n<style>\/*! elementor - v3.6.5 - 27-04-2022 *\/<br \/>\n.elementor-widget-image{text-align:center}.elementor-widget-image a{display:inline-block}.elementor-widget-image a img[src$=\".svg\"]{width:48px}.elementor-widget-image img{vertical-align:middle;display:inline-block}<\/style>\n\n\n\n<div class=\"wp-block-stackable-spacer stk-block-spacer stk--no-padding stk-block stk-02c6225\" data-block-id=\"02c6225\"><\/div>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"801\" height=\"538\" src=\"https:\/\/mfsengineering.com.au\/wp-content\/uploads\/2022\/02\/blog20.png\" alt=\"Efflorescence on the wall\" class=\"wp-image-22825\" srcset=\"https:\/\/mfsengineering.com.au\/wp-content\/uploads\/2022\/02\/blog20.png 801w, https:\/\/mfsengineering.com.au\/wp-content\/uploads\/2022\/02\/blog20-300x201.png 300w, https:\/\/mfsengineering.com.au\/wp-content\/uploads\/2022\/02\/blog20-768x516.png 768w\" sizes=\"(max-width: 801px) 100vw, 801px\" \/><\/figure>\n\n\n\n<div class=\"wp-block-stackable-spacer stk-block-spacer stk--no-padding stk-block stk-18630bb\" data-block-id=\"18630bb\"><\/div>\n\n\n\n<ol><li>Water-soluble salts must be present within the masonry structure.<\/li><li>There must be enough water to carry and transport the salt to the surface of the masonry structure.<\/li><li>A channel or path for water to travel through to the surface of the masonry structure must exist.<\/li><\/ol>\n\n\n\n<p>It is impossible for efflorescence to occur unless each of these conditions is met. Therefore, in order to prevent efflorescence from forming, builders must simply regulate these conditions.

No excess water should be allowed into the masonry structure during construction or during the structure\u2019s lifetime. This can be achieved by designing and installing an adequate drainage system to deter runoff water from the structure.<\/p>\n\n\n\n<div class=\"wp-block-stackable-spacer stk-block-spacer stk--no-padding stk-block stk-155f766\" data-block-id=\"155f766\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\">Use a dense grout<\/h4>\n\n\n\n<div class=\"wp-block-stackable-spacer stk-block-spacer stk--no-padding stk-block stk-6375403\" data-block-id=\"6375403\"><style>.stk-6375403{height:30px !important}<\/style><\/div>\n\n\n\n<p>Creating a dense grout by using a mechanical vibrator during construction will greatly limit the presence of voids within the material, making it very difficult for the free water (and salt) to travel through the masonry structure and onto the surface.<\/p>\n\n\n\n<div class=\"wp-block-stackable-spacer stk-block-spacer stk--no-padding stk-block stk-bf0013b\" data-block-id=\"bf0013b\"><\/div>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" width=\"747\" height=\"497\" src=\"https:\/\/mfsengineering.com.au\/wp-content\/uploads\/2022\/02\/blog19.png\" alt=\"Efflorescence on the wall\" class=\"wp-image-22824\" srcset=\"https:\/\/mfsengineering.com.au\/wp-content\/uploads\/2022\/02\/blog19.png 747w, https:\/\/mfsengineering.com.au\/wp-content\/uploads\/2022\/02\/blog19-300x200.png 300w\" sizes=\"(max-width: 747px) 100vw, 747px\" \/><\/figure>\n\n\n\n<div class=\"wp-block-stackable-spacer stk-block-spacer stk--no-padding stk-block stk-d1bc782\" data-block-id=\"d1bc782\"><style>.stk-d1bc782{height:30px !important}<\/style><\/div>\n\n\n\n<p>Learn more about types of building damage <a href=\"https:\/\/mfsengineering.com.au\/building-damages\/\">Here<\/a>.<\/p>\n\n\n\n<p>Today, we have all the tools and knowledge available to prevent problems like efflorescence.
