The French Drain
This older house suffered with damp rizeing up the
walls. Although sum degree of humidity is expected in older houses built with out damp corse
this problem became much worse after a new house built near by, interupted the natural corse
of a spring. It was decided to install a french drain
close to the walls of the house in order to intersept
the approaching ground water.
A trench is dug close to the walls
of the house and a permiable pipe
layed in the bottom. It is covered
with clean washed stone that supports the pipe and prevents
collaps but alows the water to find
the small holes in the pipe, colects
in the bottom and drains away. The
entire trench is back filled with stone untill 4inches from the ground level where its covered with
geo text and this is then secured with the rest of the stone.
