Weeping Tile Installation Toronto

Underpinnings.ca is the GTA’s go-to place for weeping tile installation. Our experts will inspect your home before making recommendations on what maintenance should be done in your home.


Weeping tiles are also known as drain tiles or perimeter tiles. They are porous pipes used to collect underground water. Small slits in these plastic pipes help them collect moisture that would do damage to a home or building.


The name “weeping tile” can be a confusing term for homeowners because it is not a tile. The original systems consisted of sections of terra cotta clay pipe that would allow water to weep into them and the weeping system drained water away once it entered the pipe hence the name weeping tile.


Nowadays it is generally plastic pipes that are covered over with aggregate rocks to prevent too much soil from falling through the slits and clogging the weeping tile. These rocks allow the water in the surrounding soil to flow into the pipes. The water is then drained into a solid pipe where it flows towards a discharge drain or into a sump pump.


This type of drainage system is best left to a professional. We have done hundreds of these and know exactly what to do to help keep any moisture from settling next to your Toronto home. It is best to do this job right the first time to save you time and money.

What Are Weeping Tiles?

Weeping tiles are an essential element of drainage systems in both residential and commercial properties. Traditionally made from terracotta, these tiles are now usually constructed from corrugated plastic pipes with small slits or holes that redirect water away from buildings. They are installed underground around the perimeter of foundations or beneath basement floors to prevent water accumulation, which can lead to structural damage and dampness.


The benefits of weeping tiles include providing a cost-effective solution for water management, offering long-term protection against water damage, relieving hydrostatic pressure, increasing the value of your home, and enhancing the overall environment of your basement by keeping it dry.

How Does The Weeping Tile Work

How does the Weeping Tile Work

Your basement walls would effectively sit in a puddle of water for their entire life without the ability to drain water that has pooled or accumulated at the base of your foundation. Given the porosity of concrete, poured concrete or cinderblock concrete, mortar joints, or mortar binding blocks pooling of water at the base of your foundation can be avoided with the above structures.


Therefore, if water surpasses these structural modifications then year after year they could weaken your foundation and thus risk damaging your foundation walls. Providing a drainage point that will drain water that has accumulated at the base of the foundation into the sump pump liner installed under your basement floor is the purpose of weeping tile.

Signs that you need

a weeping tile

Standing Water in the Basement

The presence of standing water in the basement indicates that the drainage system of your house has become completely unusable. If this happens, then the weeping tile has been clogged up for a long time and cracks have already appeared in the foundation walls through which water seeps outside the house.

Cracks in the Basement Walls

Cracks in the walls are another sign that accumulated water outside the house is not being drained away. Concrete is porous and it cracks when constantly exposed to water.

Standing Water Around your Home

If you notice puddles around your house that remain for a long time after rain, this indicates that the soil is completely wet and the weeping tile is not doing its job. It is worth checking and cleaning the weeping tile system to prevent cracks in the concrete foundation.

Sign of Mold or Mildew

Mold and fungus appear in places with constant dampness. You may notice an unpleasant musty smell in the basement. There may also be black spots on the drywall. With the appearance of such signs, it is necessary to immediately check the performance of the drainage system.

Weeping Tile Installation Process

Weeping tile installation is not a very complicated process. However, improper installation can lead to several unpleasant consequences,

including the complete loss of its functionality. It is worth entrusting this work to professionals to get a high-quality drainage system that will last for many years. Weeping tile installation is carried out according to the steps described below.

The next step will be laying coarse gravel at the bottom of the trench. This layer serves to create space between the ground and the weeping tile. Typically the gravel layer is 4-5 inches around the weeping tile pipe. If the gravel layer is neglected, then wet soil can very quickly clog the holes with the weeping tile pipe. This can lead to complete dysfunction of this drainage system.

Next, we need to lay the PVC pipe in a trench with gravel. Holes must also be made in the pipe through which moisture will enter the pipe. Remember that the pipe should be installed just below the foundation of the house to avoid the accumulation of water on its base.

It is necessary to consider where the water will flow from the weeping tile pipe. In most cases, a sump pump is used that redirects the accumulated water from the pipe to a special tank. It is also possible to redirect the accumulated water from the weeping tile to the city's storm system. The method of connection and the connection points must be considered before installing the pipe.

It remains only to fill the trench after all systems are connected and checked. Remember to cover the weeping tile pipe with a layer of gravel first to avoid clogging it with soil. Next, you can fill in the soil dug in the first stage. This is the last stage after which it remains only to remove the debris and the remaining soil.

Our Work from Clients’ View

Water Drains With a Window Well

Water Drains More Easily With a Window Well

Window wells are an excellent solution for protecting basement windows from the ground. However, this design can be filled with water during rain. This can lead to the destruction of the walls and seepage of water into the basement through the window frame. It is necessary to take care of a high-quality drainage system to prevent this.


The best solution, in this case, is to use a weeping tile. The weeping tile pipe is much lower than the window well. To connect these systems it is necessary to install a sewer into the base of the window well and connect it to a weeping tile pipe. After that, water will not accumulate in the window well and will be redirected to the drainage system.

Frequently Asked Questions

A leaking basement will most likely continue to leak this is because most basement leaks are not a result of faulty or clogged weeping tile systems even with or without a new weeping tile. Many new homes still have basement leaks as much as they have new foundations and brand-new weeping tile installations. Therefore, from this statement, we can learn that weeping tiles can protect your drainage systems but cannot prevent basement leaks.

Weeping tile can collect water that is located at the foundation of the house. However, damage to the waterproofing can occur along the entire wall. In this case, water can get into the basement. The voids and cracks in the walls are some of the ways through which water leaks into a basement through a foundation wall. Water is ultimately kept from leaking through your basement walls by the protection against water ingress through these cracks and voids.
The job of the foundation waterproofing product applied onto the exterior surface of your foundation wall is to protect against leaks through cracks and voids. Your foundation's ability to drain away accumulated water present at the base of the foundation is enhanced by the installation of new weeping tiles. To reduce the amount of water pressure against your foundation and thus reduce the frequency and amount of water that leaks through foundation walls it calls for efficient weeping tile drainage.

Weeping tile serves to collect moisture and rainwater from the ground but uses other drainage systems to store it. The best solution would be to connect the weeping tile to the sump pump system. This will redirect all the accumulated moisture into a separate tank. From there, the water is redirected to the storm system using a special pump.

The sump pump is one of the most popular ways to store water from a drainage system. However, you can install weeping tiles without using the sump pump system. In such cases, the weeping tile is connected directly to the city's storm system. The company will consider in detail all possible installation options and discuss them with the owner of the house before installing weeping tile.

A layer of gravel is mandatory when installing weeping tiles. It performs several useful functions at once. First, it is a secondary drainage system. The presence of a layer of gravel allows moisture to seep into the weeping tile system, which collects it and redirects it through the main drainage system.
The gravel also acts as a protective layer for the weeping tile. It prevents contact between the soil and the drainage pipe. This allows it not to become clogged and perform its functions for a long time. If the weeping tile is laid in normal soil, then the holes in it will clog after the first rain and the drainage system will not do its job.

You will need a water rocket, a flexible hose, and a water faucet to make the unclog weeping tile. Put a water rocket on one end of the hose and connect the other end to the faucet in the basement. Next, you need to push the hose into the weeping tile, the edge of which is located in the sump. Strong water pressure will flush out the dirt that has accumulated in the weeping tile pipe.
Carry out this procedure several times by pushing the hose along the entire weeping tile. The result should be clean water without dirt. Cleanings can be used by the sewer camera to check the quality. If the weeping tile is not cleaned, then a partial or complete replacement of the weeping tile must be carried out.
