Common Questions about Basement Waterproofing
Why would my basement drainage system need a sump pump and battery backup?
If water can’t drain by gravity, a sump pump collects and discharges it away from the foundation. A battery backup ensures protection during power outages, which often happen during heavy storms.
What is the difference between exterior and interior waterproofing?
Exterior waterproofing keeps water from penetrating foundation walls, while interior systems redirect it after it enters. Exterior protects structure long-term, while interior is a less costly short-term option.
What is weeping tile, and what does it do?
Weeping tiles are drainage pipes installed at the footing of your home’s foundation to move groundwater away and prevent leaks. City Wide Group installs 4″ ABS piping with protective sleeves to stop sediment buildup and ensure long-lasting performance.
What can cause a leaking basement?
Water can enter through cracks, mortar joints, tie rods, or window wells. Blocked or missing drainage systems also force water to find its way inside.
Why should I be concerned about basement waterproofing?
Leaks don’t just cause dampness — they can damage your foundation, trigger mold growth, and lead to costly repairs. Waterproofing is essential to protect your investment.
What does City Wide Group’s lifetime transferable warranty mean?
We are the only company in Toronto & GTA offering a true Lifetime Transferable Warranty. Once waterproofed, your foundation stays leak-free for the life of your home — and the warranty automatically transfers to future owners.
