Perimeter and Surface Drainage

We're Drainage and Waterproofing EXPERTS!

At Flintstones, our specialized drainage crews devote their every day to doing high-quality drainage installations. All of our drainage installers are hand-picked by our professional production team and assigned to a project which best utilizes their talents.

Each drainage crew is headed by a crew chief whose responsibilities include: managing their team while onsite, documenting the construction process by way of photos, filling out safety and project checklists, and most importantly providing you with the best service possible.

Water Damage

Defective perimeter drains are the most common source of basement flooding and foundation deterioration in Victoria. Debris, plant roots or old and broken drain tiles can cause improper drainage. As a result, rainwater can pool up next to your foundation, causing major problems not limited to flooding. Water damage can cause a multitude of problems, including dangerous black mold on the inside of your home, which can cause health issues for you and your family.

Bad smells, structural damage, and dangerous toxins may be caused by leaking drains. Water leaking out of drain pipes can saturate surrounding soils and loosen foundations, footings, and structural supports. Many homes in Victoria have outdated systems that are damaged or non-functional. Even worse, some homes do not have a drainage system at all! The best thing you can do to prevent unnecessary and costly damage to your home is to ensure that your drainage system is functional by getting a CCTV camera inspection by the Flintstones team.

Camera Inspection

Whether you suspect your home has a perimeter drainage problem, you have a leaky basement that defies explanation or you think your drains may be in need of maintenance, Flintstones can help. A Flintstones representative will thoroughly inspect your property to investigate any potential problems. In some cases, an exploratory excavation outside the home will be recommended in order to ascertain the type and condition of the current drainage system.

A camera inspection is always required to allow us to see an obstruction (see photo), collapsed or damaged areas, the intrusion of roots or to map the location of connections to or from the weeping tiles. A trained Flintstones technician inserts a small camera into the drain and along your sewer or drain tile. We set up a monitor and capture screenshots so that you can observe the drain yourself and view its condition. Learn more about our camera inspections here.

Mold Remediation

Mold is a common occurrence in old and new homes. With the increase of “tightening” homes for energy efficiency, mold and mildew can flourish. If you have living quarters in the basement or a suite below ground level, then mold could be present in your walls, ceilings, cupboards, etc. We use CCTV cameras and state of the art electronic equipment to detect mold spores both in the air and on the surface. Our experts use professional and highly effective containment practices to remove mold from your home.

Moisture Detection

Flintstones can perform a moisture detection test to identify and assess unusually wet areas of a home. Excess moisture and humidity left within a building or its structural elements cause rot, mold growth, and reduced insulation values, as well as cause failure of flooring, roofing and wall support. Non-invasive meters, such as the one we use, are effective for initial troubleshooting and inspection, quickly indicating the location of elevated moisture and its source.

Finding a Solution

Once the appropriate inspections and tests are complete, a Flintstones waterproofing expert and your consultant will review their inspection findings and provide you with options on how to best repair and prevent moisture problems in your home.



If the inspections and tests reveal a problem with your perimeter drains that cannot be remedied by a power flush or auger, it may be suggested to update and upgrade your perimeter drain system to today’s standard.

Today's Standard

A continuous system of PVC or ABS piping is the modern drainage system used today. Two high-density and continuous pipes create a system to carry rainwater away from the roof and the base of the foundation.
The 2 pipe system is BC building code; all new drainage systems in Victoria must be built this way. On average, 60 percent of water that enters an outdated weeping tile system is rainwater from the roof of the house that runs into the gutter and down the downspouts pooling up next to the foundation of your home. A 2-pipe system consists of: A perforated pipe right at the base of the house that carries groundwater away from your foundation and a 3 inch pipe that is connected directly to your downspouts in order to carry rainwater away to the lateral line or storm drain. This system completely inhibits water from the downspouts from pooling at foundation!

Surface Drain Systems

Catch basins, or inlets, and surface drains used in conjunction with a 2-pipe drain system will remove large amounts of surface water from an affected area. These are typically used in low areas of turf
landscapes, hardscapes, driveways, and parking lots. Depending on your property, we may suggest to have these drains installed.

California Drains

California (or Channel) drains are linear surface drains connected together to a length appropriate for the specific installation. Runoff water collected in the drain is discharged to end outlets, or catch basins all of which are connected to drain pipe. Channel systems operate on the same principle as a roof gutter. Instead of grading a deck surface to a low area, the deck is gradually sloped in one direction or
plane, and the channel drain acts as a perimeter drain at the edge of the slope.

Perimeter Drain System

However, not all drainage issues are the same. Unlike many other drainage and waterproofing companies, we pride ourselves on providing drainage solutions that are tailored to the specifics of your home. For example, often times older Victoria homes had their foundations built on large rock beds. When an exterior drainage problem occurs, simply replacing the drain tile or perimeter drains won’t necessarily solve the problem. In this case, we are able to offer both interior and exterior drainage solutions to solve the problem.
