Q: How much disruption does underpinning cause?

Underpinning is a significant structural project, so there will be noise, dust, and limited access to parts of your basement while work is underway. Our crews complete the work in carefully planned stages to maintain full support for your home at all times. Before starting, we explain the full process, timing, and what to expect day-to-day so you can plan around the disruption. Once finished, you’re left with a stronger foundation and a more spacious, usable lower level.

Q: Can I do waterproofing and underpinning at the same time?

Yes. In fact, combining waterproofing and underpinning is often the most efficient and cost-effective option. Because underpinning requires working right at the foundation level, it creates an ideal opportunity to add or upgrade waterproofing and drainage systems at the same time. This approach can reduce overall disruption and ensures your newly lowered basement is both structurally sound and well-protected from water.

Q: Why do basements leak?

Basements can leak for many reasons, including failed or aging exterior damp-proofing, clogged or broken weeping tiles, poor grading around the home, foundation cracks, high groundwater, or blocked drains. In older homes, original waterproofing systems may simply have reached the end of their lifespan. A professional assessment helps pinpoint the true cause so the repair plan addresses the source of the problem instead of just treating the visible symptoms.

Q: What is basement waterproofing, and why is it important?

Basement waterproofing is the process of preventing unwanted water from entering your basement or foundation. It can include crack repairs, membranes, drainage systems, sump pumps, grading improvements, and more. Proper waterproofing helps protect against mould growth, rot, structural deterioration, and damage to flooring, drywall, and stored belongings. It also makes your basement more comfortable, usable, and attractive to potential buyers.

Q: How does interior basement waterproofing work?

Interior basement waterproofing usually involves cutting a narrow trench around the inside perimeter of the basement floor, installing a drainage pipe or channel, and connecting it to a sump pump or floor drain. As water collects at the base of the wall, it’s intercepted and carried away before it can reach your finished floors and walls. This method is especially useful when exterior excavation is not practical or when you are planning to finish or renovate your basement.

Q: What is the cost of waterproofing a basement?

The cost of waterproofing depends on several factors: the size and depth of your foundation, whether work is done inside or outside, soil conditions, access for excavation, and the extent of existing damage. After a site visit, we provide a detailed, written estimate so you know exactly what is included. In many cases, addressing water issues early is significantly more affordable than dealing with a major flood or structural repair later on.

Q: What’s the difference between interior and exterior basement waterproofing?

Exterior waterproofing stops water at the outside of your foundation by sealing the walls, installing membranes and drainage boards, and adding or replacing weeping tiles at the footing. Interior waterproofing manages water that has already reached your foundation by capturing it along the inside perimeter and directing it to a sump pump or floor drain. Both approaches are effective when used in the right situations, and in some cases a combination of interior and exterior work offers the best long-term protection.

Q: Can small cracks in the foundation cause major basement leaks?

Yes. Even hairline cracks can allow water to seep through under hydrostatic pressure, especially during heavy rainfall or spring thaw. Over time, that steady trickle can widen the crack, damage finishes, and lead to more serious structural problems. Having foundation cracks inspected and repaired early is usually far less expensive than waiting until they turn into major leaks.

Q: What areas around Vancouver do you service?
