Foundation Crack Repair Go to Diagram >

As with all exterior repairs, Wal-Tech Drainage begins by obtaining all underground utility locates prior to excavating. Once we’ve excavated to the footing tile we inspect the tile condition. After cleaning the wall area below grade our technicians apply a waterproofing membrane to the exposed wall. A drainage board is applied to the wall area, followed by drainage stone being laid back over the footing tile before we back fill with the excavated material or optional stone.

Complete Exterior Waterproofing Systems

When Wal-tech Drainage completes exterior waterproofing on your home, we begin by obtaining all utility locations to ensure uninterrupted and safe work around your home. We excavate all existing footing tile and either inspect or replace the existing tile. All wall surface area below grade is cleaned and the appropriate waterproofing material is applied, based on your foundational needs. Drainage boards are installed and tiles are covered with stone, which is then finished off by backfilling the excavated area.

Should it be required, we offer additional services once exterior work is complete, included, but not limited to: restoration of lawns, shrubs, concrete or asphalt

Window Well Drainage

Window well drainage is often not considered until a heavy rainfall forces water through the window seal and into your home. The professionals at Wal-Tech Drainage will assess your needs and propose a solution to fix your leaking window and prevent future leaks. This may include excavating to the footing of your home to install proper perforated drains connected to the exposed footing, preventing window well flooding.

Storm & Sanitary Sewer Repair & Installation Go to Diagram >

Your sanitary sewer transports the sewage from your home, and takes it for disposal or to treatment facilities. In some neighbourhoods sanitary sewers are separate from storm sewers, which independently carry rain runoff and other water away from the home. Wal-Tech Drainage covers repair and installation of both storm and sanitary sewers, replacing faulty and collapsing sewer lines with new, heavy plastic piping. Any final work we complete is inspected by municipal authorities to ensure your home is up to local code. Left unrepaired or in poor condition, your storm and sanitary sewer lines could face the following problems:

• Clogs
• Backups
• Slow drains
• Broken pipes
• Gurgling drains

Egress Window Installation

Egress window installation is done to ensure basement windows provide a potential escape route in case of emergency, as per local bylaws. Installation requires excavation of the surrounding earth and foundation to achieve a work area in which to cut an appropriately sized window. Wal-Tech works in conjunction with certified window professionals for basement bedrooms to comply with municipal bylaws. In addition to the window itself, we typically install a window well to aid in proper drainage for the egress window well system.

Foundation Restoration & Replacement

Wal-Tech’s foundational restoration and replacement is done when intensive repair, or replacement of older and failing foundations are necessary. After surveying your home to establish a diagnosis we work by shoring your home from the inside, or removing foundation to excavate from the outside, depending on your home’s individual requirements. We specialize in stone foundation restoration, repointing stone, and then repacking with waterproofing cements. Wal-Tech works with poured concrete or concrete block to ensure your home’s foundation is sound, and strong, and as with all our work, warranted to last.
