Fall is in the air, and that means our home and building projects turn to the outside as the temperature drops. It’s a great time to plan some concrete projects outdoors, and we are here to provide some tips.
Concrete Grinding to Level Uneven Surfaces
Uneven concrete surfaces can happen for a variety of reasons. Whether it’s from last season’s frost, tree roots growing over the summer, or a drainage issue that runs under your slabs, the uneven concrete can pose a hazard. However, by grinding the uneven surface you can create a better transition between slabs to help eliminate tripping and water drainage.
One thing to consider before starting your grinding project; most residential slabs are four inches thick. If you have a variance between slabs of one inch or more, it can be cost prohibitive and ultimately sacrifice the slab’s integrity, making it prone to crack under pressure, thereby needing to cut the portion or the entire slab and start from scratch.
Concrete Sawing and Joints for Slab Repair
If you find that the difference between slabs is one inch or more, it’s time to consider cutting it instead of grinding. It’s important to consider the cutting area and its impact to the rest of the slab in question, as well as the adjoining slab.
Concrete Cold JointsThere are two types of concrete joints when it comes to slabs. The cold joint is a joint between two separate concrete pours. If the concrete slab you are working with has a cold joint, you will probably not need to cut the concrete, and breaking the concrete will not harm the adjoining slab.
Concrete Control JointsIf you have a control joint (a joint normally one inch deep or less), you’ll be using it in a single slab, which will need to be cut to make a clean break for repair.
Proper Project Diagnosis and Resolution
Whether you are grinding a slab to make it safer, or cutting a slab to do a major repair, make sure you identify the reason for the problem and fix that before spending time and money on the concrete work.
Slab work should always be done after all of the problems that caused the concrete issue are identified and properly remedied so you don’t have any issues again once you’ve repaired your slab.
Also, make sure if you are working on a slab for a driveway or sidewalk that you know what is underneath it. There can be water lines and electrical conduit that you may end up cutting by accident. If you aren’t sure of what may lie under your slab, contact your local utility company or blue stake office so they can identify any potential problems. And, if your yard has irrigation for lawns and plants, make sure you know which way they go and mark them at the slab edges to keep an eye while you are cutting.
At Ace Cutting, we believe in doing it right the first time, because concrete work can be hard and expensive work, especially if unforeseen problems arise. To learn more about concrete grinding and slab sawing equipment, browse our many handheld and walk behind saws, or give us a call!
