Interior Drain Tile Systems
drain tile system is a collection of pipes installed around your foundation. The pipes are
perforated to allow water to drain into them. The pipes then run the water
into an interior sump pit. Homes without a drain tile system, with a
clogged drain tile system, or when the drain tile is improperly installed and pitched away from
the sump basin can find their
crawl spaces and basements flooded.
Interior drain tile systems are used as a complete solution to control
and prevent just about any type of seepage. They are designed to keep
the water table far below the bottom of the basement floor, this controls
the capillary action or wicking of water or water vapor on to the basement
floor. The procedure involves opening the floor along the perimeter foundation
wall(s) and installing a perforated drain pipe surrounded with washed
gravel at the base of the wall, then cover the gravel with a filter paper
and drain track as seen in the picture below, after we re-pour concrete
floor and clean basement. The system then collects water from multiple
sources and empties it into a sump pit.
Our typical interior drain tile installation is only about a two day process,
and comes with a
lifetime transferable warranty.
A Dry Basement
Interior Drain Tile:The most effective of the interior drainage systems is a perforated drain
pipe installed inside the perimeter of the footing. Not only are these
the most popular systems, they are also building code approved when installed
and sealed correctly. This requires removing and replacing concrete around
the slab edge.
Many homes around the nation have full or partial basements. These basements
are really reverse swimming pools. In other words, most people don't
want water in their basements. Foundation drain tile systems act as the
means by which ground water can be transported away from your basement.
If you want a dry basement, you must have an adequate foundation drainage system.
The water content in the soil surrounding your house can fluctuate seasonally.
There is always a point at which you can dig and hit water. Geologists
often refer to this as the water table. This water table rises and falls
in response to the amount of precipitation in any given time period. The
water table in many parts of the country can rise to within a few feet
of the surface during wet spells. Water will take the path of least resistance.
It can choose to go sideways through a crack in your foundation, or it
can go down alongside your foundation into a pipe. I'm sure that you
will agree that it is a better idea for the water to go down the pipe.
A foundation drain tile system has four main components. The drain tile
(pipe), the filter media (gravel), the gravel cover, and the water outlet.
All of these elements must be installed for the system to function properly.
The drain tile or pipe is usually 4" in diameter and is perforated
or has pre-drilled holes along its length. The filter media or gravel
is used to cover the drain tile. Water can flow readily through this gravel
and find its way to the pipe. Remember, water takes the path of least
resistance.The gravel that is used most often is large (1 - 1 1/2"
diameter) washed gravel.
The water outlet is simply the place where the collected water flows to.
It can be one of three places. If you build on a hillside, your drain
tile will simply 'daylight' or come to the surface. This is the
best situation, because your system depends entirely on gravity to work.
If you build on level ground, you have basically two choices, install
a sump pit or a large buried
French drain. A
sump pit is usually installed inside the basement of your The drain tile pipe
runs beneath the footer to this sump. The collected water is then mechanically
pumped from the sump.
