A Study of The Impact of Acrylic Based Surface Waterproofing on The Moisture Behaviour of Brick Masonry Through Dynamic Vapour Sorption (DVS) And Water Absorption Tests
The rate and extent of uptake and release of moisture and liquid water are critical in understanding the behaviour of masonry materials. This study focussed on testing brick masonry to identify the moisture performance difference after treated with acrylic based surface waterproofing – commonly used to lessen water uptake and improve façade durability. Brick and mortar specimens were first tested for water absorption then treated and retested 0, 12 and 24 months later to evaluate the short- and long-term impact of waterproofing on their water absorption capacity. Dynamic Vapour Sorption (DVS) tests were also conducted to quantity the change in their (de)sorptive characteristics. Results from both tests were combined to show the impact and durability of acrylic waterproofing on the moisture behaviour of brick masonry
