Underpinning and Waterproofing Company Toronto FAQ

Can I do waterproofing and underpinning at the same time?2024-03-18T14:29:51-04:00

Often, it makes sense to do both at the same time, especially if digging is already needed for underpinning. This can be more efficient and might even save money in the long run. City Wide Group can look at what your home needs and suggest doing both together if it’s the best option.

How much disruption does underpinning cause?2024-03-18T14:29:37-04:00

Underpinning can be a bit more disruptive than waterproofing because it might involve digging around your home’s foundation. But, professionals work to keep the disruption as low as possible. The process is well-planned and communicated, and many homeowners find the benefits outweigh the temporary hassle.

Does fixing my basement add value to my home?2024-03-18T14:28:54-04:00

Yes, fixing and protecting your basement with waterproofing and underpinning can raise your home’s value. These improvements make your home safer, work better, and more attractive to buyers. Homes that are well-cared for and safe from common problems like leaks and foundation damage are more appealing to potential buyers.

How long does waterproofing last?2024-03-18T14:28:58-04:00

The life of your basement waterproofing depends on what methods are used and the conditions around your home. Exterior waterproofing usually lasts a long time, sometimes decades, while interior systems like sump pumps might need checks or changes more often. City Wide Group offers basement waterproofing services that come with a lifetime warranty for some services, giving you long-term protection.

Is underpinning my house safe?2024-03-18T14:29:03-04:00

Yes, it’s safe when done by experts. Underpinning makes your home’s foundation stronger and isn’t a threat to your home when done correctly. Choosing a trusted company with good experience in underpinning, like City Wide Group, ensures the work is done right and safely.

Will waterproofing stop my basement from leaking?2024-03-18T14:29:07-04:00

Yes, waterproofing can fix your leaking basement. This includes stopping water from coming through cracks or where pipes enter your basement. We use advanced waterproofing systems and methods like installing weeping tiles, sump pumps, and waterproof coatings to keep water out. But if the leaks are due to bigger problems with your home’s structure, you might also need underpinning to completely solve the issue.

Opt for The City Wide Group for foundation waterproofing, and we promise your treated area will remain free from water or moisture entry for as long as your house stands. Our services come with a warranty certificate that is transferable to endless future homeowners.

  • Before any digging gets underway, The City Wide Group ensures all utility services are informed and the dig site is clearly marked.

  • We first reveal the foundation’s walls and base, giving them a good clean to guarantee that the new concrete will bond well.

  • To deal with any cracks or openings in the foundation, we fill them with a specific type of cement before applying a fresh concrete layer over the entire area.

  • We then secure the foundation with a RUBBER BITUTHANE MEMBRANE for waterproofing, covering both the wall and its base.

  • Additionally, we attach a DELTA MS plastic mat along the foundation wall down to the base, aiding in water drainage.

  • New weeping tiles are installed to divert water from the foundation, surrounded by clean ¾” gravel to ensure proper drainage.

  • The dug-out soil is then replaced and compacted firmly to avoid any future ground movement.

  • After the work is finished, we thoroughly clean the site of any construction debris.

  • To wrap up, we repair and reinstate any outdoor spaces and landscaping that were affected by our work.
