Things are really moving along – finally – at the basement “build-out” for TLC Construction!” Teddy has been busy watching the water proofing experts add interior drain tile after the April floods proved it was necessary before continuing the project. Last week Teddy reported they were digging a trench to put the drain tile in. What a job trucking the dirt and cement out in 5 gallon buckets; through the egress window to a wheel barrow; then into the truck. Whew! a huge job thought Teddy.
Next the water proofing experts got large rolls of corrugated, 4″ plastic drain tile. The drain tile has slots which allow water to enter but it also has a sleeve to keep sand and fine particles from permeating and filling it. They set the drain tile in the bottom of the 12″ trench. The trench goes to the new sump pump and the drain tile enters the sump basket through the side. As the drain tile is rolled out into the trench, it is cut to length and covered with 3/4″ gravel chip. Chip is different from other gravel in that all the fine material is screened out thus leaving pockets or voids between the gravel to allow the water to travel freely.
Concrete is mixed then poured over the gravel chip and troweled flat to cap off the top of the trench and restore the floor. If a new sump pump is installed, as in this case, the water will be piped up out of the sump bucket and through the side wall of the house just above the foundation. At this point, a pipe is installed to carry the water away from the house much like a downspout for gutters. After the concrete is cured (1-2 days) work can resume to finish the project.
