Foundation repairs are essential when a building’s foundation starts showing instability. Problems like settling, cracks in walls or floors, or foundation heaving can happen because of soil pressure, added structural load, or moisture. Here’s a guide to understanding foundation repair and its causes, methods, and solutions. Have a look at this superior yard works
Causes of Foundation Damage
Water is often the main cause of foundation damage. When soil under a building gets too much moisture, it can expand, and when it dries, it contracts, leading to movement in the foundation. Additionally, natural events like earthquakes, floods, or droughts can impact foundation stability, especially in areas with high-clay-content soil.
Common Foundation Repair Methods
Here are some popular ways to fix foundation issues:
Sealants and Masonry Patches
Small foundation cracks can sometimes be fixed using waterproof sealants or masonry patches. Promptly addressing minor cracks is important because they can let in water and worsen over time. Hydraulic cement, epoxy, silicone, polyurethane, and vinyl concrete are common sealants frequently utilized to protect against moisture. While this approach works for minor damage, it’s best to monitor these repairs and take immediate action to prevent further issues.
Slab Jacking
Slab jacking, also known as mud jacking or concrete lifting, raises sunken concrete slabs by injecting material under them. This method is often used for lifting concrete structures like stairs, porches, and driveways. To fix a sinking foundation, small holes are drilled into the concrete, and a mixture is pumped underneath to fill gaps and lift the slab back into place. This technique is widely used because it’s relatively simple and effective.
Piling or Piering
Piercing involves excavating soil layers to position concrete or steel piers directly beneath the foundation. In contrast, piling entails driving piles deep into the ground until they reach stable soil. Common techniques used in these methods include steel-pressed piling, bell-bottom piers, and concrete piers. These long-lasting techniques effectively restore the foundation to its original level and help prevent further settling.
Soil Modification or Stabilization
Soil stabilization involves strengthening the ground beneath the foundation by adding materials to fill gaps and firm up the soil layers. This method is similar to slab jacking but requires skilled professionals for accurate results. Although soil stabilization can be more costly due to the expertise and materials needed, it’s especially beneficial for homes built on unstable or expansive soils.
Choosing the Right Foundation Repair Solution
There are various foundation repair options, and the right solution depends on the severity of the damage and your budget. Some fixes are quick but temporary, while others are longer-lasting.
