Weeping Tile & Waterproofing

A weeping tile is an underground drain that collects the groundwater, relieving the wall from “hydraulic pressure”. The weeping tile usually drains into a storm city drain or into a sump pump/sanitary line.

An Interior weeping tile is a lower-cost alternative to exterior Waterproofing repairs. If you have a lot of obstructions around your house like decks, additions, driveways, or extensive vegetation, you may want to consider an interior weeping tile system complete with a sump pump to control your water infiltration. This process is done in 3 easy steps.

First Step: Preparation of Affected Area
Our First step is to protect your bellowing. We Instal staircase, flooring, and Ventilation system protection to make this project safe. The affected area is clear of any obstruction, followed by a visual inspection with the client.

Second Step: Installation
Removal of frost wall and electrical/insulation in the affected area if needed. Jackhammering around the edge of your basement walls. Excavate beside footing to install a new weeping tile system connecting to a new sump pump system, backfilled with washed rock. A drainage board was installed on affected walls, creating a barrier and forcing infiltrated water to flow into the new interior weeping tile system. Re-pouring concrete floor over the new weeping tile and drainage board to create a seamless installation.

Third Step: General Clean Up and Demobilization
Cleaning the area and removing safety measures properly to have a return back to a normal house. To ensure client satisfaction, we will have a visual inspection after work completion.

Estimated time for the installation process: ~1 week
Estimated cost for installation: 170$ L/ft

**To keep in mind. The removal of walls prior to installation may affect the price. We also offer complete restoration of the affected area after installation.

If your house has a sump pump, part of the weeping tile can be inspected from there. That is the best way to determine if the weeping tile is functioning. In the case that the house doesn’t have a sump pump, often there is no way to visually inspect the weeping tile without excavating down to the footing of the foundation wall. Once the pipe is exposed in one or more locations, we use a pipe camera system to inspect its condition.

When your weeping tile is malfunctioning, the ground surrounding your foundation will remain saturated. The saturated ground will expand with the frost in the winter months and push against your foundation which creates cracks in the concrete wall allowing water to seep in. The large amount of precipitation that falls in the Edmonton area is bad news for homeowners if your weeping tile is not functioning properly. The accumulation of water in the ground creates hydraulic pressure which presses against your foundation and inevitably the water will find its way into your basement.

A weeping tile system can get plugged due to a variety of reasons:

• Roots of surrounding vegetation
• Silt accumulation from surrounding ground overtime
• Aging of the tile system
• Poor installation from the previous contractor
• Sub par materials used

There are many steps involved in repairing a weeping tile, each with its own costs associated with them.

A discovery excavation and inspection can cost between $1000 and $1500.

If there are light roots, sediment, or other fine materials that are plugging the pipe, we have a flushing system we utilize to clear the pipe from one location which would save costs in needing to dig those sections.

The cost for this varies depending on the extent of the clog.

In the event the pipe needs a complete replacement, there are many variables that would affect the cost to do so. These include, but are not limited to:

• Size of work area
• Depth of excavation
• Pre-existing and desired landscape
• Concrete walkways or driveways

The average cost to replace the pipe ranges from $200 to $400 per linear foot.

In many cases, a new weeping tile system also requires a sump pump installation. The cost for this ranges from $2200-$3000.

The weeping tile may be compromised by noticing infiltration of water in multiple areas where no visible foundation crack would be.

The presence of large trees, silty grounds, and improper installation can cause the weeping tile to fail.

Waterproofing is typically performed after the water has found its way inside your basement walls, or at the same time as the weeping tile repair.

We use only the best materials on the market, adjusted for the condition of the concrete wall. We offer a 20-year warranty, but your basement is likely to stay dry for the next 30-50 years with proper maintenance!

The waterproofing will likely take place at the same time as the weeping tile repair. The cost of the waterproofing typically ranges from $90-$400 per linear foot.
