Abstract
© 2015, Emerald Group Publishing Limited. Purpose – Experimental field test apparatus has been used to determine the inter-variability and intra-variability floodwater ingress rates of the masonry wall of a domestic building, before and after preparation with an improved surface treatment procedure. The purpose of this paper is to discuss this issue. Design/methodology/approach – Replicated and repeated simulations of floodwater conditions (600 mm head) outside a building were created, before and after the wall was treated with a combination of mortar admixture and surface impregnation. Findings – Untreated and treated floodwater ingress rates were 4.99 litres/hour (234.99 litres/hour/m2) and 1.74 litres/hour (81.90 litres/hour/m2), respectively, and display high intra-variability before treatment. These preliminary results indicate water penetration through masonry is linked to the initial rate of absorption of brick units and perceivably the workmanship of the bricklayer. Originality/value – Reductions in floodwater penetration from outside a building, by the impregnation and admixture treatments of masonry walls, can be achieved to manageable levels. However, the target for rates of water ingress through permeable masonry of
