Protect Your Property with Proper Drainage

Calgary's clay-heavy soil and dramatic freeze-thaw cycles put serious pressure on foundations. Without proper drainage, water accumulates, leading to basement flooding, foundation cracks, and structural damage.

PeakFlow designs and installs underground drainage systems that move water away from your foundation and keep your basement dry. We work with new builds and retrofit existing properties.

What We Offer

  • Weeping tile installation and repair
  • Sump pump installation
  • Foundation drainage systems
  • French drain installation
  • Storm water management
  • Catch basin installation
  • Grading and slope correction
  • Backwater valve installation

A properly designed drainage system is an investment that protects your home for decades.

Basement water is not always a drainage problem. Sometimes the source is inside: a blocked floor drain or a partially collapsed sewer line that shows up on a camera inspection during drain cleaning, or a failed water heater tank. We check the cheap possibilities before recommending excavation, because excavation is the most expensive answer and it should never be the first guess.

Underground drainage is the one part of a build nobody sees again once the slab goes down. Long sweeps instead of tight bends, a cleanout where a camera can actually reach, and consistent grade are what decide whether this line gives trouble in ten years. This was the below-slab phase of a Calgary commercial project. The overhead hot, cold and recirculation lines for the same building are on our water heater and hot water page, and the shower rough-in they feed is on our shower and bathtub installation page.

FAQ

Frequently Asked Questions

Why does my basement flood every spring?
Spring flooding usually comes from meltwater sitting against the foundation because the grade slopes inward, the weeping tile is blocked or collapsed, or the sump pump cannot keep up. Those three causes have very different fixes and costs, so the assessment matters more than the sales pitch.
What is weeping tile and does my house have it?
Weeping tile is perforated pipe run around the base of the foundation footing that collects groundwater and carries it to a sump or storm connection. Most Calgary homes have it, but in older houses it is often clogged, crushed or disconnected.
Do I need a sump pump?
You need one if your weeping tile drains to an interior pit rather than to a gravity storm connection. If you already have a pump, the useful questions are how old it is, whether it has a backup, and whether it is sized for the volume it actually sees during a heavy melt.
What does a backwater valve do?
A backwater valve stops city sewer from flowing back into your home during a surcharge event. It is one of the least expensive protections against a genuinely damaging basement backup, and it is worth asking about if your home does not have one.
How disruptive is drainage excavation?
It is real excavation, so it affects landscaping and access for a few days. We scope exactly what gets dug, what gets restored and what does not, in writing, before starting, so there are no surprises about the state of your yard.
What areas do you serve?
We serve Calgary and the surrounding communities of Airdrie, Cochrane, Chestermere and Okotoks. If you are just outside those boundaries, call us and we will tell you honestly whether we can get to you.
Are you licensed and insured?
Yes. PeakFlow Plumbing and Heating is fully licensed and carries comprehensive liability insurance, and all of our work meets Alberta building and safety codes. We are happy to confirm our credentials before you book.
What are your hours?
We are open Monday to Friday from 7AM to 5PM and Saturday from 8AM to 4PM. We are closed Sunday. Leave a message outside those hours and we will get back to you on the next business day.
Do you provide free estimates?
Yes. We provide free quotes on most plumbing and heating projects. Call (825) 773-1297 or send us the details through the form on this page and we will give you an upfront price before any work starts.
What payment methods do you accept?
We accept cash, cheque, e-transfer and major credit cards. Payment terms are agreed upfront before work begins, so there are no surprises at the end of the job.
