Plan and Prepare

The anatomy of an installation. Note that the depths may vary depending on the project and your soil.

Make a plan. A good plan is essential to a successful paver project. Think about where you want your path, driveway, or patio, and then use graph paper to make a scaled drawing of the immediate area. Draw in your paver project. You'll have to play around with your design a bit, so be sure to use pencil and keep your drawing neat. Your project will need to have adequate drainage if you want it to be safe and durable. You'll also want to make sure that it slopes away from your house and other structures. To ensure adequate drainage, you should have a slope of at least 1/8" per linear foot (1/4" slope per linear foot is often recommended).

Even simple, monotonous paving projects can look great. You can do a lot more with pavers, though, so consider making patterns or unusual shapes. Order your materials. You have a lot of choices in the pavers you use. Most are brick or concrete, but you can find a variety of sizes, shapes, and colors. Find a style that is to your liking and that fits your budget either online or at your local builders supply store. In general, if your project area isn't too irregularly shaped, you can safely calculate how many pavers you need by simply measuring the square footage of the footprint and adding 5 percent. If your design has a lot of curves, get an extra 10% over your best square footage estimate. You should order a bit extra because you'll almost certainly end up having to cut some of the pavers to get the right fit. The fancier your outline, the more pavers you'll have to cut.Safety (OHS) is to be in accordance with legislation, regulations, codes of practice, organisational safety policies and procedures, and project safety plan and may include:

1.1 Measuring and Levelling Hand Tools

Measuring Hand tools and instruments are precise devices but needed to be handled with extra care, e.g. Spirit level should be checked every day before use! Spirit level It is used to control the horizontal and vertical alignment of wall surface and edges. The length is at least 80 to 120cm long. It is made of metal, synthetic material or wood. It has two measuring bubbles: one is located at mid length is used to check horizontal positions. While the second one, at the end, is used to check vertical position. This tool requires always to be handled with care and needs to be checked from time to time weather it is still working accurate or not.

Spirit level Plumb bob A plum bob is made of metal. When suspended from a vertically attached string, it is employed to check the vertical alignment of corners and surface of walls. A freely hanging plumb bob gives exactly the vertical al
