Garage Crack Leveled and Sealed, Richmond Hill, ON Garage Crack Leveled and Sealed, Richmond Hill, ON

A home in Richmond Hill, Ontario had a large crack across the concrete of the garage and one side of the crack, quite a bit of the concrete had settled. There were also other hollow spots beneath other areas of the floor that would have worsened over time. The crack also allowed for water to seep in and wash out the substrate, which would lead to further sinking and settlement. The homeowner was trying to sell the property and was worried that the state of the garage floor would scare off buyers.

The customer called Canadian Concrete Leveling and spoke to John DiNicolantonio who explained the work that would be done to the garage. Kyle McKeown and Steve Langton came in and used our PolyLevel Foam System and NexusPro Joint Sealant. Our PolyLevel Foam System was injected beneath the concrete to lift and level the slabs. The foam lifted the cracked garage back to the same level, leaving no tripping hazard and the ability to use NexusPro on the crack to ensure no water could seep through. The customer was extremely satisfied with the work completed. The floor looked better than they ever imagined it would and they were also quite happy that we warranty the area for 10 years, so the new homeowners do not need to worry about it.

  • Condensation
  • Leaky basement windows

Expert Foundation Repairs and Concrete Lifting in Richmond Hill, ON

Tilting basement wall in need of repair in Richmond Hill, ON

Many of the foundation problems that homes face look larger and more complex than they might actually be. The main reason for most foundation problems is shifting, weakened soil that can no longer support the weight of the structure. Some of the major signs of foundation problem in you home are:

  • Uneven or sloping floors
  • Cracks in the floor, interior wall, or exterior wall
  • Inward bowing walls
  • Sagging floors over a crawl space
  • Hard to open windows and doors
  • Tilting chimneys
  • Street creep

If you have uneven concrete on your floors, sidewalks, or patios, then you need the professionals at Clarke Basement Systems to install the PolyLevel Concrete Lifting System. the PolyLevel solution is injected under the concrete to raise it to the right height, making it a faster, easier, and more cost effective solution, not to mention it lasts longer than tradition methods. 

Crawl Space and Mold Repairs in Richmond Hill, ON

As a part of the house that can often be neglected, a crawl space can become a breeding ground for mold, mildew, and even small animals or other pests if left unchecked. When this happens, trust the experts at Clarke Basement Systems to install vapor barriers, thermal insulation and dehumidifiers to turn your dirty, musty crawl space into a healthy, energy-efficient space. 

Major signs of a crawl space problem:

  • Sagging floors
  • Condensation
  • Mold
  • Wood rot
  • Foundation problems

Mold can be a silent killer in your home which is why you should have your home inspected regularly. Wood rot can also be a huge problem because when left unchecked, it can eat through wood, making it incapable of holding up the floor above the crawl space. We can install crawl space jack posts to correct sagging beams and keep your home a safer place. 

Clarke Basement Systems is committed to customer service because we are proud to serve our area. Let our team of knowledgeable staff and certified technicians find a solution that will work for both your home and your budget. Call us today for a free estimate!

Job Stories From Richmond Hill, ON
Heaving Foundation in Garage, Richmond Hill, ON

A home in Richmond Hill, Ontario, had a heaving foundation in the Garage because of frost and was sinking due to improper soils. This was damaging the home's foundation and causing cracks in bricks. The homeowner was worried the Foundation wouldn't hold the house from falling down.

The customer called Clarke Basement SystemsClaude Mathieu explained the solution for the home. Don Clarke and the team installed Push Piers, drainage membranes, insulation and filter stone. The piers stop the sinking and the drainage membranes and insulation is to protect against frost damage. Proper drainage of ground water directed away from the homes foundation and the insulation makes it hard for frost damage.

The customer was satisfied that they no longer have to worry about damage to the foundation.
