No <br />attempt should be made to completely stop the <br />water flow, Previously dirty sand boils must be <br />monitored. <br /> <br />A particular problem in individual flood fights <br />is the placement of sandbags against foundation <br />and basement walls. This action may cause <br />more damage to the structure than the flood <br />waters. The tremendous water pressure <br />exerted on the foundation can easily collapse <br />walls and flood the building. <br /> <br />20 <br /> <br />e <br /> <br />e <br /> <br />e <br />
