ABSTRACT:
A unique water drain system is utilized for eliminating subgrade water which usually accumulates below ground level and causes cracks or leaks in the concrete foundation. The present system is uniquely designed to be used with permanent wood foundations. A basket-retainer is used to contain and prevent the spread of crushed stone out of position. The crushed stone allows the water to flow through it and to a drain tile. The retainer has a water-permeable membrane around or lined in it to prevent soil or debris from clogging up the crushed stone conduit.
