Concrete Slab Cost for a Shed

Concrete Slab Cost for a Shed

Concrete can be poured by the concreters by a mobile truck or made up on-site using a concrete mixer. Buying and installing a large concrete slab of pre-made concrete will cost much more than the cost of simply laying down some plywood and then putting some bricks or blocks on top. Concrete can be made up of gravel or sand mixed with water, cement and some other additives which help to make the concrete slab stronger such as wire mesh and metal rods by the concreters. ## How much does a concrete slab cost for shed Before beginning with your slab job, kindly note the cost of concrete slabs the different in type and size. The cost of a concrete floor or the cost of concrete slabs for garden shed is generally charged per square metre. Based on the [type of concrete](/guides/concrete-products/what-is-concrete-made-from), the concrete slab price per square metre (per m2) are as follows: - Plain concrete slab structures: $60- $85 per m2 - Spray-on concrete slab surface: $50- $75 per m2 - Reinforced concrete slab surface: $65- $90 per m2 - Decorative stencilled concrete slab: $100- $150 per m2 - Exposed aggregate finish concrete slab: $100- $150 per m2 - Coloured concrete slab: $75- $90 per m2 These prices of slab for a shed are exclusive of any labour charges. That's because most factors behind this include thickness (more thickness means more labour), location of the house and ease of accessing the area. An easily accessible area will mean less cost. The details of the different types and categories for your slab will help you with the quote. ## Concrete slab cost per square metre Concrete slab cost per square metre for your shed can vary depending on the thickness of the slab that you want. If you are going to use a thinner or less dense concrete then it will not cost as much as using a [denser concrete](/guides/concrete-products/concrete-mixing-ratio). Concrete slab prices depend on the [concrete finishes](/guides/concrete-decorative-resurfacing/what-is-burnished-concrete), thickness of the slab, and more. Concrete slabs cost as follows per square metre based on the location in Australia: - Western Australia: $40- $55 - New South Wales: $35- $50 - Queensland: $30- $45 - South Australia: $30- $45 - Victoria: $25- $40 - ACT: $20- $35 The cost of concrete slabs are sometimes charged per cubic metre. Similarly, the house slab prices range from $64- $108. The rates don't change frequently, so don't worry about the budget difference due to different rates. The thickness is again important to know the final cost of the slab for a shed. The cost and price of slabs for sheds are subject to change sometimes though. Most people charge an average $45, while most also charge a low price. All the costs depend on the property. ## The process to concrete a slab yourself Follow the following steps to [cure a concrete slab](/guides/concrete-products/what-is-concrete-curing) for your shed. 1 Breaking the ground with a pickaxe or shovel. 2 Putting down mesh to assist in the circulation of cement and help hold it together as well as to provide reinforcement for the slab once it is poured. This is otherwise called concrete slab foundation. 3 Adding gravel and sand which are mixed with water, Portland cement and other additives from buckets into wheelbarrows then pour this mixture on top of the mesh until the required level is reached. The thickness of the slab depends here. If building this thing for durability, keep the thickness high. 4 Attaching wooden slats that are laid on top of concrete blocks or bricks, adding some wire mesh for strength and rebar before pouring concretes over top of them using a form made from wood boards connected by stakes that support the mould above ground while allowing concrete to set below. 5 Once the concrete has been set, removing wooden slats and wire mesh before adding a layer of polyester or similar dense material on top to create a smooth finish for the furniture. The amount of time needed to complete the process will vary depending on how many people you have available and their skill level. If you work alone then this job may take over one day but if you have 2-3 strong helpers this job can be completed in just 1-2 hours. ## The process to have a concrete slab poured by a professional The cost of concrete pouring services include labour as well. Here's the process: - Breaking the ground and adding mesh into the foundations where they want to pour the concrete. - Using a truck that has a large mixer on it that will pour down cement, sand, gravel and water in various proportions to make the concrete within approximately an hour depending on how much is required. - Smooth out the concrete with a power trowel after it has hardened enough. ## How long does concrete take to dry? The drying process for the concrete slab will depend on the climate. If it is a hot and sunny climate then it may take only 1-2 days to dry but in colder climates, where it is wet and damp then this process will take longer. Once the concrete has dried, a layer of polyester or similar material is added on top to create a smooth finish for the shed floor before you install your shed onto it. Adding [metal supports or steel mesh](/guides/concrete-formwork/what-size-steel-mesh-for-a-concrete-slab) underneath where the frame will be placed and bracing them in place using brackets secured with bolts so they are strong enough to support the weight of heavy items. ## How thick does a concrete slab need to be for a shed? This depends on what you are planning to put in your shed. If it is just for storage then a few centimetres will be sufficient, however, if you want to install any machinery or equipment inside your shed, make sure the concrete slab in the sheds is thick enough to support the weight as well as keep it from sinking into the earth. But this will increase the costs. The costs increase if the thickness is high. The costs are low if the thickness is less. You can make it up to 10-15 cm thick as this will support the weight of heavy machinery and equipment easily. The amount of time needed to complete the process will vary depending on how many people you have available and their skill level. ## How do I make a concrete slab level? All you have to do is before you pour any concrete for your home shed project, it is important to level the ground first as a sturdy foundation will make this slab building project easier and quicker at home. If your soil is not level at the site then you can even out the area by piling it up on one side of the foundation until it is perfectly straight and level. Once you have levelled the ground, you can then start pouring concrete into the 8-inch deep trench that has been formed. Check the slab level with a line made out of chalk or a spirit level to ensure that it is straight and level. ## How do I waterproof my shed floor? Once you have poured your concrete slab for your shed project, if you would like to make sure it is completely watertight from the inside of the shed then you can use a waterproof coating to coat the entire surface. This will prevent any moisture from leaking through from the inside, and it will also protect your concrete slab. This is a great idea if you live in a humid climate as this will prevent moisture from seeping into the concrete which can cause cracks to appear over time or may even lead to mould growing within the cracks.

How Much Does a Concrete Driveway Cost?

How Much Does a Concrete Driveway Cost?

A poured in place concrete driveway is a higher-end style of installation because the concrete mix is shaped in place. The price of a concrete driveway can vary depending on the size, design and type. Typically an entry-level driveway costs between $70 and $90 per square metre. For a more decorative driveway, you can expect to pay between $80 and $150 per square metre. ## Unsealed concrete driveway cost An entry level unsealed concrete driveway costs around $70 to $90 per square metre. An unsealed driveway is made from a [plain concrete slab](/guides/concrete-products/what-is-a-concrete-slab), normally around 150mm thick and can be as wide as required. The plain concrete is not coloured concrete or textured and will need to be sealed with oil or paint after installation to prevent it from being damaged by environmental factors such as sun, rain and traffic. Unsealed driveways are the most cost-effective but do require ongoing maintenance which does contribute to their overall lifetime cost, final cost and other cost data. Asphalt drives have been a popular choice for many years because they have relatively low installation costs. They often require more frequent maintenance because the asphalt surface or any flat surface needs to be resealed every 3 to 4 years. ## Sealed concrete driveway cost A sealed concrete driveway costs around $80 to $120 per square metre. A sealed driveway is a concrete slab with a coloured concrete and driveway texture surface. Concrete is available in more than one colour. This gives it a much higher quality look and provides better durability and protection against the elements than an unsealed plain concrete driveway. The plain concrete driveway is normally between 200mm to 300mm thick, depending on your preference, and can be as wide as required. Sealing does add to the overall cost of concrete and cost of the installation because it requires specialised preparation techniques such as diamond grinding before sealing can take place. ## Poured in place concrete driveway cost A poured in place concrete driveway costs around $100 to $170 per square metres. [Poured in place](/guides/concrete-pumping-services/what-is-concrete-pumping) concrete driveway is a higher-end style of installation because the concrete mix is shaped in place using lightweight screeds and moulds. The result is a much smoother finish especially decorative finishes and other decorative elements that look very similar to an asphalt drive but at a lower cost depending on cost of concrete. Poured in place concrete driveways are not generally suitable for steep concrete driveways or ones with curves because it would be too hard to pour concrete in these areas. This method does require specially prepared ground so the concrete driveway can support the weight of heavy vehicles including cars, trucks and commercial vans. Unlike many other types of construction work, there are no standard concrete driveway costs, exposed aggregate driveway costs or an average cost that apply to every concrete driveway project. There are just too many variables involved which ultimately affect the final price you pay for your new driveway! These factors include size, design, location and the overall quality of the installation and the type such as a stamped concrete driveway, asphalt driveway and sloped driveway. ## Is it cheaper to pave or concrete a driveway? If you are looking for a slightly lower-end drive, you could consider the installation of asphalt. Asphalt is a cheaper flat surface to install, but it requires more frequent maintenance. However, if you want a high-end drive that is going to last for years and withstand all weather conditions, stencilled concrete may be a better option. If you have a dilapidated driveway, you might be able to [pave over it](/guides/concrete-products/can-you-pave-over-concrete). The best concrete driveway options include using a contractor. Contractors will charge you for the job including materials and labour, but they will be able to provide you with an accurate estimate of what your project should cost depending on the concrete cost. If you plan on doing it yourself, there are two factors that you need to consider when choosing between asphalt and concrete: the price of materials and labour involved in the concrete driveway installation. Brisbane City Council has a great guide to the [technical standards of driveways](https://www.brisbane.qld.gov.au/laws-and-permits/laws-and-permits-for-residents/footpaths-and-driveways/driveway-permits/driveway-technical-standards). Make sure you check with your local authority however. ## What is paving? Paving is the process of installing a hard, durable surface that is resistant to weathering and other natural damage. Paving surfaces are used to create paths, walkways, concrete driveways, parking lots and roads. A typical paving project starts with the excavation of all vegetation (if needed) and any existing surfacing driveway materials (such as gravel). The site will then be graded for drainage before laying down any sub-base, base or pavement layers on top of compacted or [exposed aggregate](/guides/concrete-products/what-is-exposed-aggregate) or sand. After this has been done successfully you can begin application of the asphalt, standard premixed concrete or concrete surface material. ## How to remove oil stains from concrete Being a car owner means you have to deal with oil stains as well as other spills on your concrete driveway. However, this doesn't mean that your concrete driveway is doomed to look bad for years as it is [pretty easy to clean](/guides/concrete-decorative-resurfacing/how-to-clean-concrete-driveway). There are some tips and tricks that can help you get rid of the stains as a DIY project and remove dirt from your existing driveway over time. Overall, it requires less maintenance and helps save money that you expect to pay for concrete services, small cracks and other factors. The best way to remove an oil stain from your old driveway or old concrete is by using hot water and dish soap. Mix the solution in a bucket and soak the stained area with it. This should eliminate most of the stain from the entire driveway. You can also use soda or bleach, but be careful since they might damage the concrete if left there for too long. Make sure that whatever substance you choose, test them in an inconspicuous place first to see how they react to the concrete and if they cause any damage. ## What should I use to seal my driveway? What you need to do is protect your concrete driveway from environmental factors such as water, dirt, oil stains etc. There are a number of products on the market that can help you with this issue, but here are some things that you have to consider before purchasing one: - Price. Make sure that the product fits within your budget before buying. - Compatibility with the existing surface material. - Depending on what has been applied to your existing driveways, you may not be able to use certain products. Check the label on the product for this information. - UV Resistance. If there is currently any sealer applied to your driveway, make sure that whatever you are buying can withstand sunlight. This will prevent fading or flaking of your surface material. - Quantity. Find out how much of the product you need before buying it. If it's too little, you might have to purchase extra which could end up being more expensive than just getting a bigger package in the first place. - Application method. There are three methods that can be used when applying an asphalt or concrete protectant namely sprayers, rollers and brushes.

Frequently Asked Questions

Why do I need to have my aggregate concrete sealed?

This concrete has an open pore design and a larger surface area so the surface is more vulnerable to damage from water and contaminants.

If I have recently installed a new aggregate driveway, will it be sealed?

Sealing is the final step in aggregate concrete installation and most reputable companies include this as part of their installation services.

How do I know if it needs re-sealing?

Generally speaking, aggregate driveways need to be re-sealed once every two years. Commercial premises may be re-sealed more often.

What is Cement and how is it made?

Cement is a type of binder, a substance that sets and hardens when added with water, or any other inert durable materials like stone and sand.

What is the difference between Cement and Concrete?

Cement is an additive that provides the basis for the glue that holds concrete. Concrete is a mixture of aggregates and sand with water and cement.

What can Concrete be used for?

Buildings, bridges, slabs, piping, inside and outside flooring, streets, driveways, are some instances where concrete may be applied.

What is involved in Polishing Concrete?

Polishing concrete involves grinding concrete that has been treated with a chemical densifier that removes blemishes, and increases density.

What does exposed concrete mean?

After the concrete has been placed, a surface retarder is then applied to delay the top layer of cement from setting.

Do we need soak wells?

Areas that are fully surrounded by walls (no matter how low) where water has nowhere to go will need a soak well.
