The French Drain

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 course

this problem became much worse after a new house built near by, interrupted the natural course

of a spring. It was decided to install a french drain

close to the walls of the house in order to intercept

the approaching ground water.


A trench is dug close to the walls

of the house and a permeable pipe

laid in the bottom. It is covered

with clean washed stone that supports the pipe and prevents

collapse but allows the water to find

the small holes in the pipe, collects

in the bottom and drains away. The

entire trench is back filled with stone until 4 inches from the ground level where its covered with

geo text and this is then secured with the rest of the stone.
