What is the process of forming concrete?

Step 1

Wet concrete on skin can cause everything from mild redness to third-degree, permanently disfiguring chemical burns. You and your helpers should take these steps:

  • Wear eye protection. Sandy concrete splashes can wreak havoc with your eyes.
  • Wear long pants and long sleeves to protect your skin.
  • Wear tall rubber boots if you have to wade in wet concrete.
  • Wear gloves (rubber gloves are the safest bet).
  • If your clothes get saturated with wet cement, remove them, thoroughly rinse your skin and change into clean clothes before going back to work.

Prepare the Site

Contact your local building department to see whether a building permit is required and how close to the lot lines you can build. In most cases, you’ll measure from the lot line to position the slab parallel to it.

Start to prepare the site for concrete by driving four stakes to roughly indicate the corners of the new slab and use a line level and string or builder’s level to see how much the ground slopes. Flattening a sloped site means moving tons of soil. You can build up the low side or dig the high side into the slope and add a low retaining wall to hold back the soil.

  • Pro tip: Your concrete slab will last longer, with less cracking and movement, if it’s built on solid, well-drained soil. If you have sandy soil, you’re in luck. Just scrape off the sod and topsoil and add gravel fill if needed. If you have clay or loam soil, you should remove enough to allow a 6- to 8-in. layer of compacted gravel under the new concrete.

If you have to remove more than a few inches of dirt, consider renting a skid steer or hiring an excavator. An excavator can also help you get rid of excess soil.

  • Note: Before you do any digging, call 811 or visit call811.com to arrange to have your local utilities locate and mark buried pipes and wires.

Family Handyman

Every concrete placement is unique. Every customer has different needs, and each property’s location requires its own planning. And we enjoy the variety! But we still follow the same general procedures each time we handle a concrete installation whether it’s a residential or commercial concrete project.

When you contact us with interest in our concrete pouring services, we’ll schedule a free,-no-obligation consultation with you on your property. We’ll discuss your desires, tell you what we can do and answer your questions. If you decide to hire us as your concrete contractor, we’ll provide you with a contract stating the specifics of the work we promise to do. And then, the real work begins!

1. Site Preparation

Our first job on any site is to clear it and clean it, and often this requires earth-moving equipment. Any grass, trees, old concrete, or anything else will need to be removed so we can work on the raw earth. After clearing and marking the exact dimensions for the concrete, we’ll lay a granular sub base over the entire area. The sub base is then compacted to prepare it for the concrete.

2. Setting Concrete Forms

Our next step is setting concrete forms. Forms are set along the edge of the entire concrete area, and they’re held in place with wood or metal stakes. Both stakes and forms are designed for easy removal once the concrete has cured.

3. Pouring the Concrete

When the final forms are in place, it’s time to install the concrete. We may be able to pull our ready mix concrete truck up to the site and pour directly into the forms. If this is not possible, we use our concrete pump to get the concrete exactly where it needs to go. Our crew will smooth and move the concrete as it is being poured to prevent air pockets and ensure an even surface.

4. Pre-Finish

Next we level the top of the concrete and make the edges look uniform. We screed the surface, which means slowly pushing a large board across it to compact the concrete. Then hand held trowels called floats are used to even out smaller areas and edges. Depending on the finish the concrete will receive, we might perform an additional steel trowel finish to create a hard, smooth surface.

5. Finish

Now that we’ve prepared the surface, we can apply finish to the concrete. Our customers choose a multitude of finishes including stamped, and textured, and smooth trowel.

6. Curing

At this point, the concrete can rest and start the curing process. We do recommend a curing compound be applied immediately after the finish as it helps the concrete cure evenly and reduces cracks. Either way, the entire curing process lasts 28 days, but the first week is the most critical. You’ll want to follow our time recommendations before walking and driving on your new concrete surface!

Concrete is extremely durable and low-maintenance. However, there are a two things that can help prolong its life. 1) A good quality sealer, applied the same day the concrete is placed or within a month afterward. 2) Occasional soap and water cleaning. Both these things will minimize the chances of staining or discoloration.

At R&M Concrete, we enjoy helping people improve their properties. If you have further questions about our concrete pouring process or concrete in general, we’d be happy to answer them!
