What Causes Concrete Slabs to Settle?

Settling concrete slab

Have you noticed cracks opening up in your concrete floors? Are windows that used to open and close easily suddenly sticking or unable to completely close? Have some doors begun to jam or fail to latch? It’s possible that you are experiencing some sinking in the concrete foundation of your home in the Ottawa area.

 

Dry and sinking soil

 

Drought and heat are only a few of the outside elements that might be causing your concrete foundation to sink. Foundation settlement can lead to major structural problems, but fortunately there are ways to resolve these issues without completely tearing out your foundation and starting over. During dry spells, trees and shrubs start grabbing all the water from the ground that they can. This can lead to problems specifically in areas around Ottawa where homes rest on soil that expands and contracts a great deal depending on the moisture levels. Even settling of a concrete foundation causes minimal to no damage, but environmental factors such as moisture levels, landscaping and sunlight ensure that soil is rarely homogenous around a home resulting in uneven settlement.

 

Soil washout

 

Plumbing and displaced soil can create a void under a concrete slab when plumbing lines are installed below concrete slabs. Sometimes concrete slabs can leak, resulting in uneven leakage of soil from under the slab that can cause a void where the concrete can crack and settle. Puddles and other signs of moisture in a crawl space may indicate poor drainage around the perimeter foundation. Concrete slabs can support a tremendous amount of weight, but only when the supporting soil below them is evenly supporting the concrete itself.

 

Fill soils are poorly compacted

 

If you’re not familiar with a building site, you might be surprised to learn that the soil underneath your concrete slab is unlikely to be solid. It could well be a combination of trash leftover from the building site, rocks and fill soil with various levels of compaction. Sometimes as a home settles the fill soil underneath the concrete slab can shift out unevenly, causing footings to move as the fill soil consolidates beneath the weight of the slab. The slab can then begin to crack as it settles into the void left by the fill soil.

 

While a shifting concrete foundation sounds scary, working with a licensed local professional basement and foundation professional like City Residential Foundation Repair can offer peace of mind and options much less invasive than breaking up the concrete slab under your home and starting over.

A JOB WELL DONE BY 'CITY FOUNDATION'

I would have no hesitation in recommending City Foundation. They fixed up my foundation last summer and although the old house produced a few surprises, the professionals at City Foundation got around the problems cheerfully and completed the work. From the start, Chuck kept me informed of all of my options. If I asked for something not already in the plan, he would try to accommodate me if at all possible Chuck and his colleague Don were friendly, and respectful. They showed up every day, put in a solid day's work and always left the property clean, neat and safe for us to move around. And, the price was fair with no surprises. Great guys, good job!

Excellent service, friendly

We had Chuck and his team repair a crack in our cold storage room - they were punctual, neat, and friendly. The job was completed very quickly with great results. Would definitely hire them again and recommend them to friends.

Good job!

Chuck did a very good job. He promised to be finished by a certain date and he was good to his word. He kept me informed of his progress through pictures sent to my email account while I was at work. My backyard is nicely landscaped and there was no damage or debris left in my yard - just a new window well and no basement leaks.

Can't say enough about the workmanship of Chuck and his crew. They assessed the problem(leak in the foundation) quoted me a price, booked appointment, showed up on time and did a very professional job.The work site was cleaned up to the point it was hard to tell there had been any serious digging at the site. If I have similar problems with my foundation they will be the first people I will call!! I would not hesitate to recommend Chuck and his crew if you have foundation problems that need repair.

Professsional and Polite

My experience with City Residential was very positive. I had a crack on my foundation and knew we needed it fixed. They came in and addressed the situation and did the work cleanly and professionaly. Our property was kept nice and tidy during the repairs and they worked safely during the work. Its been a few years now since the work and no issues whatsoever. I will be using them again once we decided to fix a few areas around the garage that they pointed out would need fixing someday. Very happy and positive experience.

Foundation Crack (back) and Drainage (front)

The foundation crack at the back was difficult to get to and difficult to dig out. The work was done well and on time. the drainage trench at the front was also done very well and on time. I hope I don't need Chuck again but if I have foundation, drainage issues, he will be my 1st call. bc

This is a highly professional company with reliable, honest service. Chuck, the owner, came exactly when promised, took the time to listen to my concerns, explained the problem in an easy to understand language, described in great detail how it could be fixed, and what was - and what was not - necessary. Chuck and his team's attitude and service were at all times very honest, courteous and highly professional. Although I needed to be out of town, there were no surprises or additional costs, and everything was left tidy and clean. Chuck even followed up a couple of days later to check if everything was all right and done to my satisfaction. All in all, I was very impressed with the quality of work and the services received and would highly recommend the company.

City Residential Foundation Repair

Chuck Naish and his team from City Residential Foundation Repair were excellent to deal with in every aspect. Their level of integrity throughout the entire process was outstanding. They were honest, respectful and their ability to explain the process and the solution options were extremely helpful to us. The scope of the project was big, however Chuck walked us through every step of the way; assessment, testing, options and repairs which resulted in a very successful outcome. In addition, Chuck and his team were able to complete the necessary repairs with minimal impact to our newly completed landscaping which included a lot of hard scape, tiered armour stone, gardens and a pool. They kept the work site impeccable over the duration of the project. We have and will continue to highly recommend Chuck Naish for his very professional and skilled foundation repair work.

My experience with City Residential was great. Chuck was very friendly and very easy to deal with. I especially appreciated that he was able to come by and do the estimate in the evening when I was off work. They did the work exactly as they said they would, no surprises (which in my mind is the most you can ask for). I was really surprised by how clean they left everything in the evenings and when the job was complete. They will definitley be the first people I call if I ever need more foundation work.

Weeping Tile system replaced

We are very please with the work that was done. It was always a pleasure to speak with the owner and explain to him what was going on. Although we found the job to be pricey, it is impossible for us to determine if it was adequate or not at it's hard to compare to others. He ran into several problems at my house while doing the job and he took it upon himself to call the City at two different occasion so they could do some testing before he could go on. Safety was very important for them so they took all the necessary precaution so that no one could get hurt or fall into the hole that were done all around the house.
