For DIY concrete work use a ready-mix crack-resistant cement mix. Create a wood frame around the area you want to place concrete. Pour a layer of concrete mix and then add a steel reinforcement balls layer on top. Spray paint around the outside of the cement Install the rebar securely in place Tap the sides […]

On average, a 20×20 slab costs $2,468. The cost per square foot is between $4 and $8 on average. However, most homeowners spend on average between $5.35 to $6.17 per square foot for both materials and installation. The final cost depends on slabs thickness, size and any special reinforcement, e.g., wire mesh or rebar.

A concrete slab is a major structural feature of modern buildings. Slabs have a thickness of between 100mm and 500mm and are used to build horizontal surfaces like ceilings, floors and roof decks.

Whether you pour cement for a footpath or patio, a strong shingle base is required to prevent the cement from cracking and shifting – this is especially important in clay soil because it doesn’t drain well, which results in water residing underneath the cement and slowly eroding the soil.

This is 600 square feet, or a little under 56 square metres (slabs normally measured in feet) Going off the amount of $75 to $110 per m2, that would be between $4200 and $6050. 

On average, concrete slabs can cost anywhere from $75 to $110/m2. Factors influencing this are Size of job/ area Thickness of slab Any finishes/ decorations on top Accessibility If your slab is going on a flat plot of land with no access issues, expect the price to be on the lower end of the scale. If it

Adding a layer of concrete over existing concrete doesn’t join the two because the cement in the concrete doesn’t have a natural bonding agent. That means the concrete sits as a separate layer on top of the existing one. Thus, it doesn’t produce a robust and serviceable floor. Additionally, when you bond a block of

This is dependant on the overall reason. for the slab, but the minimum should be 5cm. If the slab is thicker, this means it will be stronger and more durable, so for residential constructions,  we normally go off the minimum of 10cm for a concrete shed or house slab. A house concrete foundation might be

Concrete driveways last longer than the asphalt driveways. However, concrete is quite expensive to install. Besides, concrete can easily crack during winter or suffer damage in case you use the wrong de-icing products. On the other hand, Asphalt is flexible; thus, less likely to crack. However, it requires more maintenance than concrete. But it is

4 inches. For a non-reinforced pavement, a thickness of four inches is standard for passenger car driveways. However, for 5 or 6 inches thickness, reinforcement is necessary, and such breadth works well for heavier vehicles.
