Our Projects

Basement Waterproofing & Drain Projects Across the GTA

These are real DrainCom job sites: basements, backyards, side yards and city sewer connections in Toronto, Mississauga and across the Greater Toronto Area. Just our crews, our trucks and the work we do every week.

PROJECT TYPE 01

Exterior Basement Waterproofing

When water is coming through the foundation wall, the most permanent fix is from the outside. We dig down to the footing, clean and seal the wall, and add a drainage membrane and new weeping tile so water is carried away before it reaches your basement.

  • Excavation to the footing, by hand or machine
  • Foundation wall cleaning, crack sealing and membrane
  • New weeping tile and clear stone backfill
  • Landscaping and walkways restored after the job

PROJECT TYPE 02

Interior Waterproofing & Basement Leak Repair

When digging outside isn’t practical (a finished patio, a shared wall, a tight side yard), we waterproof from the inside. We cut the perimeter floor, install interior weeping tile and a dimple membrane, and send the water to a sump pit.

  • Perimeter floor cut and interior weeping tile
  • Dimple membrane on foundation walls
  • Sump pit and pump tied into the new drainage
  • New concrete poured and finished

PROJECT TYPE 03

Foundation Crack Repair

A leaking crack in a poured foundation is one of the most common calls we get, especially after a wet Ontario winter. Most cracks can be sealed from the inside without excavation, and we’ll tell you if yours can.

  • Leaking wall and corner cracks sealed
  • Water staining and efflorescence cleaned up
  • Exterior repair when the crack needs it
  • Covered by our transferable warranty

PROJECT TYPE 04

Sump Pump Installation & Replacement

A sump pump is the quiet hero of a GTA basement, until it quits during a spring thaw. We install new pits, replace tired pumps, add battery backups, and help with the city rebate paperwork where it applies.

  • New sump pits and submersible pumps
  • Pump replacements and check valve upgrades
  • Battery backup systems
  • Discharge lines routed away from the foundation

PROJECT TYPE 05

Backwater Valve Installation

A backwater valve stops city sewer water from backing up into your basement during heavy storms. We install mainline full-port valves and handle the permit, locates, final inspection and the rebate application for you.

  • Mainline full-port backwater valves
  • Permits, locates and city inspection handled
  • Rebate paperwork for Toronto, Mississauga and Peel
  • Clean-outs for easy future maintenance

PROJECT TYPE 06

Sewer Line & Drain Repair

Tree roots, collapsed clay pipe and old cast iron are common in older GTA homes. We replace broken sewer lines under basement floors, through side yards and out to the city connection, then leave the site clean.

  • Under-slab drain and stack replacement
  • Side-yard and front-yard sewer excavation
  • Trenchless options where they fit
  • Photos of each stage sent to you

PROJECT TYPE 07

Drain Camera Inspection & Hydro Jetting

Before we recommend digging, we look. A drain camera shows exactly where the root, crack or blockage is, and high-pressure jetting clears grease, roots and debris from lines that just need cleaning.

  • Camera inspection of main drains and sewer lines
  • Locating the problem before any digging
  • High-pressure hydro jetting
  • Clear recommendations with no upselling

PROJECT TYPE 08

Weeping Tile & French Drain Installation

Old clay weeping tile collapses and clogs over time, and water ends up in your basement. We remove failed tile, install new perforated pipe in clear stone, and add French drains to pull water away from problem areas.

  • Old clay tile removal and replacement
  • New perforated pipe bedded in clear stone
  • French drains for wet yards and side yards
  • Mini excavator access for bigger jobs

PROJECT TYPE 09

Window Well Repair & Installation

Rusted or poorly drained window wells are a common source of basement leaks. We replace old wells with new corrugated steel wells, add a proper gravel drain, and connect it to the weeping tile below.

  • New corrugated steel window wells
  • Gravel base and drain connection
  • Rusted and leaking wells replaced
  • Covers available to keep out snow and debris

PROJECT TYPE 10

Concrete Basement Floors & Floor Drains

After a drain repair or waterproofing job, the floor has to go back better than it was. We pour and finish new basement concrete, lower floors, and repair or replace old, rusted floor drains.

  • New concrete basement floors
  • Floor drain repair and replacement
  • Concrete restored after drain and sump work
  • Neat finishing, even in spots no one will see

PROJECT TYPE 11

Water Service, Backflow & Plumbing

We also take on the plumbing side: replacing old lead water services, installing backflow prevention assemblies, and roughing in new washrooms and water lines.

  • Lead and old water service replacement
  • Backflow prevention assemblies
  • New washroom rough-ins
  • Water lines to garden suites and additions

How Every DrainCom Project Runs

Big excavation or a single floor drain, the process is the same.

1. Inspect first

We look before we quote, usually with a drain camera. You see what we see.

2. A clear quote

One price, the options explained, and any city rebates you qualify for.

3. Permits, locates, done

We book the permits and utility locates, and send photos as the work goes in.

4. Clean up & warranty

We leave the site clean and back the waterproofing with a 25-year transferable warranty.
