How to Choose a Concrete Contractor
You should be able to tell whether your concrete needs repairing by the sound of the material. In some cases, it can be difficult to tell the difference between a broken concrete or a delaminated section if the sound is not consistent. In this case, you can use a hammer or a spray paint to mark the affected area. A sound concrete sends back a dull hollow sound that does not ring as loudly as a delaminated one. If you're not sure, use a tape measure to gauge the area. In addition, if possible, take a video of the problem to document its severity.
In the case of a large crack in a concrete slab, you may want to use a concrete repair material that is formulated for larger cracks and craters. Although these types of concrete repair materials are generally easier to use, a two-component mixture may be more complicated but have more favorable properties. One important thing to look for in a repair material is low shrinkage. If it shrinks too much, it will debond and cause a weak bond. Bond strength is another important factor in a repair material. A good bond is vital because if it fails to bond properly, the repair will be considered a failure. Moreover, good surface preparation will help you achieve a strong bond.
Another important factor when deciding on a concrete repair is the age of the damaged concrete. Many repair materials have a higher strength early, which reduces their service life. Additionally, the ingredients used to make these repair products often contain substances that can lead to shrinkage cracks. The materials that you use may also be more brittle than the concrete they are intended to repair. If you're unsure of your requirements, you can seek a professional concrete consultant like Solid Concrete Conroe to complete a thorough evaluation.
