How To Install A Perimeter Interior Drain?

This video demonstrates the installation of an interior perimeter drain in a basement with water and moisture issues. The pipe was laid and topped with concrete, and the floor and “Block Walls” were coated with “Xypex” a waterproofing material. The process typically involves excavating the perimeter of the basement floor, installing the drain tile system, connecting it to a sump pump, and then backfilling the area. Proper installation of an interior weeping tile system helps extend the useful life of the foundation.

Exterior drain tile is installed around the outside perimeter of a foundation, collecting groundwater and draining it away before it can seep. A trench is made around 2 feet wide, or twice the width of the drainage pipe, and the entire pipe lies below. The trench is cleaned with an appropriate slope to the sump.

To install a French indoor drain, cut the floor about 12 inches deep and 12 inches wide around the perimeter. Clean the trench with an appropriate slope to the sump. Most detail drawings suggest placing a footing drain next to the footing, but some builders prefer placing the drain pipe on top of the footing. The drain is run as close as possible on either side of the wall, around the house, and back to the sump pit.

Installing drain pipe in a basement is best done by a professional wet basement service using heavy equipment and high-quality products.

How do interior perimeter drains work?

A perimeter drain is a pipe with a perforated interior and an exterior mesh sleeve installed around the exterior of a building to allow water to enter and drain away from the foundation, preventing the accumulation of soil.

How is a perimeter drain constructed?

Perimeter drains are designed to filter water from homes by installing a perforated PVC or plastic pipe covered in a mesh sock. The pipe is installed in a trench along the home’s perimeter and covered by layers of gravel. The gravel allows water to filter through the pipe, which slopes away from the house and directs it towards the main sewer system or another outlet. Older homes may also use clay or concrete tiles called “weeping tiles” for the same purpose.

How deep should a perimeter drain be?

To install an exterior french drain, you need to dig a trench around the perimeter of your footing, at least two feet wide and six feet deep. This trench should be shallow for slab-on-grade homes. To prevent clogging, place a permeable mesh sock over the drain pipe. Alternatively, install an interior drain by breaking up your basement floor, installing the drainage system, and rebuilding the floor. The team at Superior has the experience and expertise to install foundation drainage systems correctly.

The required materials for proper foundation drainage include stone, various types of stone, pipe or tile, and the preferred placement of stone around the drainage. Different drainage solutions may require different materials, and the team at Superior can provide guidance on the appropriate materials and materials for the job.

Does perimeter drain need to be sloped?

It is imperative that perimeter drains be connected to a solid pipe that runs to daylight on a sloped building site, with a minimum pitch of 1/4 inch per foot. In the event that the length of the foundation exceeds 200 linear feet, it is recommended that a second outlet be added or that the outlet pipe size be increased. In the event that the aforementioned pitch is insufficient, it is recommended that exterior drains be connected to a sump pump located in the basement via a 6-inch line. In some cases, the soil conditions at a construction site may be unsuitable for the installation of a basement.

What is the problem with the perimeter drain?

Clogged pipes in perimeter drains can cause issues like seepage and cracking due to excess water pressure on the home’s foundation. Proper planning and timelines, such as installing drainage systems before landscaping, can help prevent these issues and ensure the safety of your property. By addressing these issues, you can make your project more efficient and ensure your property is safe sooner.

Do interior French drains work?

Both interior and exterior French drains provide flood and water protection in basements. However, due to the high costs and difficulties associated with installing and servicing exterior drains, it may be more beneficial to install interior drains.

Does a perimeter drain need to be sloped?

Proper sloping and functioning perimeter drains are crucial for preventing water seepage. Experts recommend a downward slope of 6 to 15 centimetres away from the foundation over a distance of 3 meters. The drainage system itself also needs to be sloped. French drains are typically 14 inches wide by 14 inches deep, with a starting point higher in elevation to create slope and gradually dropping down to the discharge point.

What is the difference between a perimeter drain and a French drain?

Perimeter drains, also known as weeping tiles or French drains, are a type of drainage system that involves a perforated pipe installed underground around a house’s perimeter. The name “tiles” comes from Henry French, who popularized the method in the 1800s. The pipe, made of plastic or PVC, has thousands of tiny holes or slits that allow water to enter and drain away from the foundation. The pipe is often covered by a mesh permeable sock to prevent soil from entering.

What pipe to use for a perimeter drain?

Perimeter drains are underground pipes made of plastic or PVC, installed around a house’s perimeter. These pipes have thousands of tiny holes that allow water to enter and drain away from the foundation. They are often covered by a mesh permeable sock to prevent soil from entering. The pipe is then covered by layers of graduated gravel, backfilled with soil, allowing water to flow towards the drainage pipe without clogging. The weeping tile slopes away from the home, carrying water towards the main sewer system.

How long do perimeter drains last?

When installed correctly, perimeter drains have the potential to remain functional for decades. However, they are susceptible to blockages caused by soil, tree roots, and other debris, necessitating cleaning every three to four years.
