Installing a Concrete Slab
Featured Product: High Strength Concrete Mix
- Measure and establish the boundaries of the slab using a measuring tape, spikes and string.
- Excavate the area to remove grass and debris. Ensure that the excavated area is pitched in a direction where water can run away from the building.
- Add forms using 2x4s and ensure they are level. Nail the forms together and remove the string.
- Lay a gravel base (1 to 2 inches in depth) using Sakrete All Purpose Gravel. This will help with any water flow or substrate movement and prevent the concrete from buckling.
- Concrete can be mixed in a wheelbarrow, mortar pan or mixer.
- Add water as needed, 3.5 to 4 quarts of water depending on the type and size bag of concrete mix. Add enough water so mixture moves freely and does not ball up. Be careful not to over water.
- Pour concrete mixture into the formed area and begin spreading throughout the area.
- Use a 2x4 to screed the surface with a rocking motion eliminating any voids and removing excess product.
Tip: A mixer is an inexpensive rental item and will make the project easier.
- Once the wet sheen of the concrete has disappeared, apply the final trowel coat. The sheen will reappear as the surface is troweled.
- Edging the material can also be done at this stage.
- Once the surface reaches its initial set, using an ordinary broom, lay it on the surface of the slab and gently drag it across the surface to create a textured, non-skid finish.
- Wait 24 to 48 hrs before removing the forms.

Calculated results will reflect how many bags are needed for Block and Brick.
Enter the number of bricks (8" x 2" x 4") or blocks (8" x 8" x16") in the box below that you plan to use for your project. The calculator will then tell you the number of bags you need based on the different size of bags we carry.
This calculator is based on a 3/8" mortar joint. All yields are approximate and do not include an allowance for waste, uneven subgrade or any other variations from the joint size and brick and block sizes noted above.
Results will change if form of measurement is updated.
