Abstract
This technical note discusses water penetration resistance studies on a solid interlocking block masonry system, adopting ASTM E 514-90 for the influence of the type of bedding (dry stacking, thin jointing, and mortar), surface finishes (stucco and plaster on one side or both sides), and simulated wind velocities (0, 50, and 100 km/h). Silblock masonry without a surface finish is suitable for rain protected and interior walls. Introduction of any form of mortar bedding (thin jointing or conventional) resulted in higher dampness than the dry-stacked specimens. With respect to dampness, plastered dry-stacked masonry performs better, whereas with respect to leakage, plastered thin-jointed masonry performs better.
