Basement Waterproofing Nepean

Wet basements in Nepean? You’re not alone.

Nepean is one of Ottawa’s largest west-end communities. Most of its established neighbourhoods, City View, Craig Henry, Arlington Woods, Parkwood Hills and the Lynwood Village side of Bells Corners, were built between the 1950s and the 1970s. Those mature homes have weathered more than fifty Ottawa freeze-thaw winters. Their original foundations and clay weeping tile are now well past their prime. That is where most of our foundation waterproofing and sealing work in Nepean begins.

Unlike the deep Champlain Sea “Leda” clay of Ottawa’s east end, much of Nepean sits on west-end glacial till, sand and fill, with pockets of that sensitive clay mixed in. It still freezes and thaws more than thirty times a winter, which works cracks open in mid-century poured and block foundations. Lower-lying streets that drain toward Pinecrest Creek and the Ottawa River also carry a high water table each spring. On Nepean’s mature, tree-lined lots the bigger issue is often age: fifty-year-old clay weeping tile silts up or collapses. Roots from established trees also find their way into old sewer laterals.

What we see most in Nepean

• Aging or collapsed clay weeping tile under 1950s–70s City View, Arlington Woods and Bells Corners homes
• Cracked or porous mid-century poured and block foundations after fifty-plus freeze-thaw winters
• Tree-root intrusion in old sewer laterals on mature, tree-lined Nepean streets

Close to Ben Franklin Place, the Centrepointe Theatre, Algonquin College and the wider Nepean area, if your basement takes on water, we’ll find the source and stop it.

It’s not only waterproofing, we also handle foundation repair in Nepean: leaking cracks, bowing walls and settlement, common where Ottawa’s Leda clay shifts with the seasons.
