FRENCH DRAIN STYLE DRAINAGE SYSTEM

Abrégé français

Il est décrit un réseau d'évacuation rappelant une pierrée qui fournit une solution aux problèmes dinfiltration deau. Le système consiste en des tuyaux qui rappellent une pierrée et qui comprennent des rabats bilatéraux. On installe une première rangée de tuyaux périphériques au niveau de la semelle de la fondation, lesquels tuyaux sont perforés le long de la moitié inférieure de leur circonférence, sous le rabat de sorte que leau sous la semelle soit collectée et que le rabat qui recouvre la fondation crée un joint étanche efficace qui prévient la montée de leau. Une deuxième rangée de tuyaux périphériques située directement en dessous de la surface du sol comprend également des rabats bilatéraux. Un rabat entre en contact avec le côté du bâtiment et des perforations longent la moitié supérieure du tuyau au-dessus des rabats de manière à collecter leau en surface. Une membrane d'étanchéité joint le rabat supérieur externe au rabat inférieur externe pour créer une zone sèche est les deux rangées de tuyaux périphériques situées à proximité de la fondation de la maison.

Abrégé anglais

A French drain style drainage system that resolves water infiltration problems is provided. The system includes French drain style pipes with flaps on both sides wherein a first row of perimeter pipes is laid at the foundation footing level with perforations at the bottom half of the pipe circumference, below the flap so that water below the footing will be collected and the flap which overlaps the foundation creates an effective seal preventing water from creeping upward. A second row of perimeter pipes located just under the ground surface also has flaps on both sides, wherein one flap makes contact with the side of the building and perforations are located on the upper half of the pipe, above the flaps so as to collect surface water. Joining the upper external flap to the lower external flap is a waterproof membrane which creates a dry zone between the two rows of perimeter pipes proximal to the house foundation.

invention, that the second French drain pipe includes second perforations 20'
positioned at the bottom
half of the pipe circumference, i.e. below the pair of flaps such that any
water present below the
foundation footing will be collected via the second perforations and the pair
of flaps create an effective
seal preventing water from creeping upwards. Similarly, the first French drain
pipe includes first
perforations 20" positioned at the top half of the pipe circumference, i.e.
above the pair of flaps such that
any water present above the pair of flaps (surface water) will be collected
via the first perforations and
the pair of flaps create an effective seal preventing water from creeping
downwards. In one
embodiment, the pair of flaps radially extend from the first French drain pipe
and are positioned just
under the ground surface (not illustrated).
[15] In one embodiment, a membrane 22 (best seen in FIG. 2) is configured
to provide a dry area
between the first and second French drain pipe. The membrane is positioned
perpendicularly to the pair
of flaps and is constructed from waterproof materials. Specifically, the
membrane is positioned
perpendicularly at the end of the upper and lower distal flap. In one
embodiment, the end of each distal
flap is angled and configured to match an opposite angled surface of the
membrane providing a seal. In
one embodiment, loose aggregates 28 are provided to accelerate the flow of
surface water down to the
second French drain pipe. In one embodiment, the loose aggregates line the
exterior surface of the
membrane (best seen in FIG. 2).
[16] In one embodiment, at least one vertical pipe 24 is provided, wherein
the at least one vertical
pipe is in fluid connectivity with the first and second French drain pipes. In
one embodiment, the at
least one vertical pipe is configured to transfer the collected water in the
