ABSTRACT (Continued). <br /> <br />loaded to excessive depths, it can fail instantaneously and possibly result in injury or <br />death to occupants. <br /> <br />Closures, materials, and systems were tested to determine the effectiveness in pro- <br />tecting homes or buildings from floodwaters. The following conclusions were derived from <br />the tests: <br /> <br />. A watertight closure must have gasket material at its connection to the sidewalls <br />and bottom and must be bolted. The connections for the closure at the sidewalls <br />and floor must be continuous and sealed securely to the walls and the floor. <br /> <br />. Water will flow freely through a brick wall and along the space at any water <br />barrier between thicknesses of brick. <br /> <br />. Two layers of brick will allow a brick wall to support greater water depths. <br /> <br />. A brick or concrete-block wall can be protected against water flowing through it <br />excessively by using a thick coating with body. This type of coating must be <br />applied with great care or the wall will not be leakproof. <br /> <br />. Clear liquid coatings, even when low head pressures are present, will not stop <br />water from penetrating a brick-veneer or concrete-block wall. <br /> <br />. Epoxy, polyurethane, and asphalt coatings were not dependable in keeping water <br />from penetrating a brick-veneer or concrete-block wall. <br /> <br />. Some cementitious coatings will stop the penetration of water (under head pres- <br />sure) through a brick-veneer or concrete-block wall, but many of these coatings <br />are not durable. Two coatings were tested which were durable and diQ stop the <br />penetration of water through a brick wall. Coatings which can be painted on are <br />less expensive to apply and are as effective as any trawled-on coating. <br /> <br />. Systems tests demonstrated that a simple continuous system is the most reliable, <br />with snap connections being less reliable. A simple system which is adequate to <br />protect a building from floodwaters is given in this report. <br /> <br />Unclassified <br /> <br />SECURITY CLASSIFICATION OF THIS PAGE <br />
