All drainage systems for basements are a collection of pipes that Reliable Basement installs around your foundation. We perforate the pipes so that water drains into them and then runs into an interior sump pump. If you don’t have an interior basement drainage system, if your drain tile system gets clogged, or if the drain tile is improperly installed and pitched away from the sump pump basin, your crawl space and basement might flood.
With interior basement drainage systems, you are able to control and prevent seepage. They keep your water table far below the bottom of the basement floor, which controls the capillary action or wicking of water or water vapor on the basement floor. We have to open the floor along the perimeter foundation walls and install a perforated drain pipe. We then surround the drain pipe with washed gravel at the base of the wall then cover the gravel with a filter paper and drain trip (pictured below). When this is complete, we re-pour the concrete floor and clean the basement. The system collects water from multiple sources and empties it into a sump pit.
The most effective of all the drainage systems for basements on the market is a perforated pipe installed inside the perimeter of the footing. They are also the most popular systems. As long as your interior basement drainage system is installed and sealed correctly, they are also building code approved. To install them, Reliable Basement Services must remove and replace the concrete around the slab edge.
Around the country, many homes have at least partial basements. The last thing that anyone wants in their basement is water. Foundation drain tile systems transport groundwater away from your basement. An adequate foundation drainage system is essential to a dry basement. The water content in the soil around your house fluctuates seasonally. At some point during the year, there will be a time when you can dig and hit the water. Geologists refer to this as the water table. The water table rises and falls with the precipitation at any time. In many parts of the country, the water table can rise within a few feet of the surface during wet spells.
Water will always take the path of least resistance. Ideally, it will go down alongside your foundation into a pipe. But it’s also possible that it will travel sideways through a crack in your foundation.
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 four of these components must be installed for any drainage system for basements to function properly. Usually, the drain tile (pipe) is 4 inches in diameter and is perforated or has pre-drilled holes along its length. Reliable Basement Services uses the filter media (gravel) to cover the drain tile. It’s easy for the water to flow readily through the gravel and into the pipe. Usually, we use washed gravel that measures approximately 1 to 1 ½ inches in diameter.
The water outlet is simply the place where the collected water flows to. It can be one of three places. If you live on a hillside, your drain tile will simply “daylight,” which means it will come to the surface. This is the best situation because it’s entirely dependent on gravity. If you build your home on level ground, you have two choices: install a sump pit or install a large buried French drain. If you choose a sump pit, it will usually be installed inside your basement. The drain tile pipe runs beneath the footer to this sump. The collected water will be mechanically pumped out from the sump.
