This is a comprehensive guide for minor concrete projects you can tackle yourself.
CONCRETE CALCULATIONS
The formula for volume is: length x width x thickness
For those of you still struggling to work it out, using an online concrete calculator makes this step easier.
SELECTING THE RIGHT MATERIAL FOR YOUR SMALL DIY PROJECT
Let's start with the difference between concrete and cement. Cement is a dry powder used to bind items together. Concrete is a combination of cement, sand and gravel, available in wet or dry form. Below, we've outlined tips for two common minor DIY projects.
REPAIRING CRACKS
Assess if a crack is a simple fix or a sign of a bigger problem.
HAIRLINE CRACKS over doors and windows are likely due to settling and are an easy fix. However, if you've noticed MUCH wider cracks, it's best to get an expert in to assess the problem.
If you've noticed MOISTURE around your crack, use a hairdryer to remove moisture - if the moisture returns, have an expert assess before you fill the crack. Depending on the cause of the crack, check with your insurance to see if it is covered.
WIDE CRACKS in concrete are best filled with a concrete patching compound. Hairline cracks can be repaired with a concrete caulk or liquid filler.
SETTING POSTS
For setting posts into the ground we recommend using Quick Set Concrete. When using quick-set concrete for posts, make sure all your posts are braced and ready. Quick Set Concrete will harden in 15 minutes or even faster on a hot day.
MIXING CONCRETE METHOD BY HAND If mixing concrete by hand, you can mix concrete in an old wheel barrel, large bucket, or on an old tarp.
If using a tarp, spread it out on the ground
Measure out the materials for your concrete mix
Make a deep crater in the pile and add water
Using a shovel, fold the mix in from the sides
Continue to fold inwards and "chop" the pile to distribute water through the mix
MIXING CONCRETE METHOD USING A MIXER DRILL A mixer drill will make the task of mixing concrete less labour-intensive. You can mix concrete in an old wheel barrel or large bucket
Measure out the materials for your concrete mix
Gently move the drill and accessory all the way to the bottom of the bucket and around its sides until it is thoroughly mixed. If it is too thick, add more water. If it is too thin, add more concrete. When the desired consistency is reached, you're ready to pour the mixture.
KEY CONSIDERATIONS
If digging holes, check plans to avoid hitting water pipes or electrical wires.
Make a list of materials required before starting any project
Identify minor VS major repairs. Minor repairs are those which impact the aesthetics, not the structural integrity of your concrete. Minor repairs include small cracks, holes, chipped or spalling surfaces.
Ensure you grasp the pre-preparation steps for your specific project
Check the weather forecast before commencing your project
