Concrete
Below are some basic instructions for pouring and creating a good flat concrete pad
1. Consult the sales department or the concrete dispatcher on selecting the correct concrete mix for the project.
2. After placing and consolidating concrete, use a wood or metal screed with a straight edge to strike off and level the concrete. Immediately float the surface with a wood or metal float. A metal bullfloat is best for large slabs. Pushing and pulling the float across the slab, smoothes and knocks down the small ridges left by the screeding operation.
3. Edge the concrete with an edging tool if a round smooth edge is desired. Run the edger back and forth, using the form as a guide.
4. Cut the control joints. The grooving tool should be 1/4th the depth of the slab. Or, control joints may be sawed later.
5. Finish or trowel the concrete as desired for function, serviceability and attractiveness according to its end use. Exterior slabs (driveways, patios, sidewalks, etc.) should be sloped to drain properly. Steel troweling may not be required as a textured or broomed finish will give a non-slip surface when wet.
6. Garage or warehouse floors usually need to be level and quite smooth. Repeated passes with a steel trowel and increased pressure will produce a very smooth surface. Other interior floors that will be covered with carpet or a floor covering, usually do not have to be as exact.
7. Do not sprinkle water or cement on the concrete while finishing it. Cure the concrete as soon as all finishing is completed and the water sheen has left the surface.
8. Contact the sales department for information on special finishes such as; exposed aggregate, integral color, stamped or patterned.
9. The concrete finishing operations should be properly planned in order to achieve an attractive long life durable slab. Skilled, knowledgeable finishers are required to deal with a variety of concrete mixes and field conditions.
10. If you are unsure of your finishing abilities and seek assistance with your concrete project, feel free to contact the concrete dispatch or the sales department for names of qualified concrete finishers and contractors.
