Floor Slab Repair

Cracked Basement Floor? Water in Basement During Rains?

Your basement may be showing signs of water intrusion if it feels humid, produces a musky/moldy smell, or visible moisture spots. These signs are more common in spring and fall as rain water and snow runoff create water pools underneath and surrounding your home. Under the right conditions, the water pools build up pressure and permeate concrete, sometimes causing cracks or visible moisture spots.

Some obvious signs you may have a problem

  • Cracks in the concrete floor.
  • Basement floor dropping and separating from the wall.
  • Basement walls separating from the basement ceiling.
  • Basement wall cracks, along the walls and in the corners.
  • Pools of water in your basement or other signs of wet or leaky basement.

Solutions We Offer:

  • Installing a concrete slab support system.
  • Foundation underpinning.
  • Replacing basement floor slab.
  • Crack injection and floor rehabilitation.

Water was coming into the bedroom of my furnished short term rental income property. It was important to get it fixed quickly between guests. I did not want to dig up the front of the house at the beginning of our busiest season. Canadian Rooter responded quickly and gave me the best quote and the fastest service! I picked them from a newspaper ad and was a bit dubious. They did tell me that the best way was to dig from the outside, but I could not do that at this time of year. The crew was great, very clean. Walter, the foreman, kept in communication. They were professional and provided me with licensing papers. The work was done quickly and looks very good. They had to dig down through the basement concrete floor which necessitated removing drywall, studs, insulation. They installed weeping tiles, a strong membrane, redirected a problem drain. They do not replace drywall and studs, etc., but referred me to Ivan, a carpenter/handyman colleague who is doing an excellent job as well. Great service! I would highly recommend Canadian Rooter and will use them again. In my furnished rental business, I am often asked if I know good trades people. I will use this site for referrals! I did not know it existed until now. Thanks a lot!

Very professional and quick! We had a flood in our basement and found out it was the result of sewer back up and foundation leek. These guys came in right away and started working immediately. They were extremely neat and tidy; they showed up at 7:30am and didn't leave until 7pm. There is now no leaking at all and I would very highly recommend using them!

The Canadian Rooter crew came into my house to fix existing waterproofing that was made wrong. Foreman explained to me everything that was done wrongfully, and promised to do the job right and on time. He also understood my situation, and expenses that I had to suffer, and didn't charge me as much, as in other estimates. The guys did their job very professionally; they organized their time properly, and left their place clean after they left. THANK YOU Canadian Rooter!!!

Had a leaky basement that could not be waterproofed from exterior, so I called Canadian Rooter for an interior solution. They answered by questions and came in immediately to waterproof the side of my basement and installed a sump pump. So far so good. Quick and easy and gave me a competitive price as I received three quotes and negotiated price. Very happy with the service. Thanks

FAQ's

There are several reasons why a basement floor slab may crack, shift or drop, including:

  1. Poor soil compaction: If the soil beneath the slab was not properly compacted before the slab was poured, it can settle over time and cause the slab to crack or shift.
  2. Water damage: If there is water damage to the basement floor, it can cause the soil underneath to become soft and unstable, which can lead to the slab cracking or shifting.
  3. Improper reinforcement: If the slab was not properly reinforced with steel or mesh, it may be more prone to cracking or shifting.
  4. Changes in temperature: Extreme changes in temperature can cause the slab to expand or contract, which can lead to cracking or shifting.
  5. Structural issues: If there are issues with the foundation or walls of the basement, it can cause the slab to crack or shift as well.
  6. Heavy loads: If heavy objects are placed on the basement floor, it can cause the slab to crack or shift over time.
  7. Poor construction: If the slab was not properly constructed, it can be more prone to cracking or shifting, even if all other factors are properly addressed.

The repair options to fix a cracked, shifted or dropped basement floor slab depend on the severity of the damage and the cause of the problem. Here are some common repair options:

  1. Crack repair: For minor cracks, you can use epoxy or polyurethane injections to fill the cracks and prevent further damage. This is a temporary solution and may not work for larger cracks.
  2. Slab leveling: If the slab has shifted or dropped due to poor soil compaction or water damage, slab leveling can be an effective solution. This involves injecting a special foam material beneath the slab to lift it back into place.
  3. Resurfacing: If the damage is primarily cosmetic, resurfacing the slab with a new layer of concrete can improve its appearance and durability.
  4. Replacement: In some cases, the damage to the slab may be severe enough that it needs to be completely replaced. This involves breaking up the old slab and pouring a new one in its place.
  5. Structural repairs: If the damage is caused by underlying structural issues, such as foundation problems or wall damage, it may be necessary to address these issues before repairing the slab.

The time it takes to repair a basement floor slab can vary depending on the extent of the damage and the repair method chosen. Here are some general timelines for each repair option:

  1. Crack repair: Epoxy or polyurethane injections can typically be completed in a few hours.
  2. Slab leveling: Slab leveling can usually be completed in a day or two, depending on the size of the slab and the extent of the damage.
  3. Resurfacing: Resurfacing a basement floor slab can take several days, depending on the size of the area and the curing time of the new concrete.
  4. Replacement: Replacing a basement floor slab can take several days or even weeks, depending on the size of the area and the complexity of the project.
  5. Structural repairs: If structural repairs are required, the timeline can vary significantly depending on the nature of the repairs and the extent of the damage.
