<br /> <br />. Some clear coatings were very effective at beading and repelling water, <br />but would not keep a brick or block wall from leaking against a small <br />head of water. <br /> <br />. Of five cementitious coatings which were tested, only two have proven <br />successful over an 8-year period in the climate at Vicksburg, Missis- <br />sippi. Both coatings can be mixed to the consistency of paint and <br />brushed or rolled on the wall. One is a proprietary coating which <br />seeps into the pore space and seals the wall, and the other is a <br />coating formulated at WES, which has excellent bonding properties and <br />is relatively impermeable to a head of water. <br /> <br />. Epoxy, polyurethane, and asphalt coatings were not dependable in <br />keeping water from penetrating a brick-veneer wall. <br /> <br />Systems of durable, impermeable, flexible sheeting tests on brick cubes <br /> <br />and prototype houses demonstrated that a simple continuous system is the most <br /> <br />reliable. Snap connections are not reliable. The simple system given in this <br /> <br />report is adequate to protect a building from floodwaters. <br /> <br />Although further studies can aid in developments which will help owners <br /> <br />protect their building from floodwaters, the systems and materials described <br /> <br />in this report will allow the protection of buildings from floodwaters which <br /> <br />do not exceed a depth of 3 ft. <br /> <br />89 <br />
