Having noticed a sinking slab of concrete at your home or business premises is quite worrisome indeed. Whether you need help repairing concrete driveway sections or addressing sunken walkways, such an occurrence poses safety risks to people and could potentially damage the nearby building structure. As a professional concrete company, we are well aware of the issue at Bill’s Custom Concrete, and we want to offer some advice.
Sinking occurs because of the settlement or washing away of the soil underneath the slab. However, there are ways to fix such a problem without having to demolish the existing concrete and pour a brand-new one. In fact, our team provides modern solutions that help fix sinking concrete efficiently and with minimal disruption.
Here is the process our professionals employ to repair a sinking slab of concrete!Â
Assessment and Diagnosis
First, it is important to examine the concrete thoroughly to detect the reason behind the problem. In general, poor drainage, soil erosion, or natural settling are some of the factors that may cause such a phenomenon. Also, measuring the amount of subsidence and observing the surroundings help to ensure a lasting solution.
Determining the Repair Approach
Once the reasons for the problem have been determined, we choose a technique that will help us to lift the slab successfully. If you’re wondering how to fix sinking concrete slab issues, there are two main methods commonly employed across the industry – mudjacking and slab jacking (sometimes referred to as polyurethane jacking).Â
While the first one consists of the usage of a heavy slurry of sand and cement, polyurethane requires the pumping of lightweight high-density foam under the slab. Usually, we opt for the second approach since it requires a much smaller size of holes to be drilled and, therefore, puts less pressure on the compromised soil below.
Preparation
As we mentioned above, proper preparation is crucial to ensure the success of lifting a concrete slab. Therefore, the first thing we do before carrying out repairs is cleaning the surface of concrete thoroughly to remove all possible debris. Then, we mark the areas where holes are required to be drilled. And finally, we drill them using masonry drills that make the holes relatively small in diameter.
The Process Itself
During the concrete sinking repair phase, our approach ensures both precision and durability. Once the necessary holes have been drilled in the surface of concrete, we are ready to move further.Â
First, we install special injection ports to our holes and attach a pump. Then, if we are going to use polyurethane foam for the repair, we begin to pump it into the holes gradually until the surface reaches the desired level.Â
In order to avoid excess elevation, we pump in small portions to control the process. And, as soon as everything is done, we fill the holes up with cement paste.
Care and Maintenance after the Process
Normally, the surface becomes safe for everyday use within a few hours following repairs. However, maintaining stability is essential to prevent any further problems. If you want to ensure long-term results, it’s important to consider sunken concrete repair techniques as part of your ongoing maintenance. We strongly recommend changing the direction in which water flows, as well as adjusting landscaping so that it does not allow any additional accumulation of moisture.
Ensuring a Safe Environment
Repairing a sinking concrete slab timely helps to avoid more serious damage and expenses associated with such. Our professional techniques for lifting ensure that we can solve the problem effectively. If you’re interested in fixing sinking concrete slab issues efficiently, we’re here to help.
