<p>BASEMENT WATERPROOFING SYSTEM A method of overcoming the problem of water seeping into the basement of a dwelling or other structure includes procedures for treating a hollow basement wall and for treating the footer drainage tile system which extends perimetrically around the basement wall footer. Wall treatment is effected by pumping a hardenable filler material, in fluid form, into the hollow wall to fill and seal the hollow wall portions as the filler material hardens. The filler material also operates to fill and seal cracks formed in the outer surface of the wall. Drainage tile system treatment is effected by digging a plurality of holes at spaced locations around the perimeter of the basement wall to expose portions of the footer drainage tile system at these locations, by removing portions of the footer drainage tile system at the locations of the holes, by cleaning the interior of the footer drainage tile system, and by reconstructing the removed portions of the footer drainage tile system to provide each of the reconstructed portions with a clean-out branch having a near-ground-level access. Open upper ends of the clean-out branches are capped with novel removable cover structures. Lower regions of the holes are filled with porous particulate material to provide reservoirs for receiving and temporarily retaining water. If the footer drain tile are found to be laid at an unduly high level with respect to the basement floor, selected ones of these tile nearest the main drain conduit are replaced at a lower level and are surrounded by a bed of porous particulate material to provide a reservoir for receiving and temporarily retaining water. In some instances, a sump, a sump pump and/or a backflow prevention system may be added to improve operation of the footer drainage tile system.</p> |
