![]() Surface efflorescence on brickwork is unsightly but easily remedied. Removing efflorescence – three strategies Permeable geotextiles can prevent salt absorption from the ground. When installing pavers, ensure bedding material and grading allow for proper drainage. Mechanical vibration and dense mortar joints can remove voids from the grout and decrease porosity, slowing the travel of water and salts between bricks, blocks, or stones.Ĭertain grout admixtures can be used to improve grout flow, reduce water content, and reduce porosity.Īs a final step after mortar tooling and final clean-down, application of a hydrophobic sealer prevents external absorption of water from rain and snow. This will prevent both water entry and salt absorption. ![]() ![]() Use vapor barrier sheeting between masonry construction and the ground. Water sprinkler systems should be set up in a way to not direct water at the building or wall. This will prevent them from absorbing excess water or salts.Įnsure building plans include eaves, overhangs, and flashing to reduce the chance water has of entering the wall from above.Įnsure landscape plans include adequate runoff areas, moving water away from masonry. Store masonry materials off the ground and cover them with waterproof sheeting. Here are a few tips to prevent efflorescence during construction. On new construction, preventing efflorescence boils down to choosing materials wisely and isolating building materials from salt and water sources. To address efflorescence on brick before or after construction, prevention is more effective than removal and will save time and money in the future. Preventing efflorescence pre- and post-construction
