Question 1

What is the standard thickness for a garden shed concrete slab?

Accepted Answer

For most standard residential garden sheds, a 100mm thick concrete slab is recommended. If you plan to store heavy equipment, vehicles, or have a particularly large shed, we may recommend a thicker slab or additional reinforcement to ensure long-term durability.

Question 2

Do you handle the site preparation and excavation?

Accepted Answer

Yes, we handle the complete process. This includes site leveling, minor excavation, installing the necessary formwork, and laying a proper roadbase foundation before pouring the concrete to ensure a perfectly level and stable slab.

Question 3

How long does the concrete need to cure before I can build my shed?

Accepted Answer

You can generally walk on the slab after 24 to 48 hours. However, we recommend waiting at least 7 to 14 days before assembling and anchoring your garden shed to allow the concrete to gain sufficient strength. Full curing takes about 28 days.

Question 4

Do I need council approval for a garden shed slab?

Accepted Answer

Regulations vary depending on your local council (Brisbane, Moreton Bay, or Sunshine Coast), the size of the shed, and its proximity to property boundaries. While we build the slab to high standards, we recommend checking with your local council regarding specific permit requirements for the shed structure itself.

Question 5

Can you pour a slab in a difficult-to-access backyard?

Accepted Answer

Absolutely. We specialize in small concreting projects and are experienced in working in tight or difficult-to-access areas. We can use wheelbarrows or arrange for a concrete pump if direct truck access isn't possible.

Question 6

Does the slab need to be exactly the same size as the shed?

Accepted Answer

We typically recommend making the slab slightly larger than the shed dimensions (usually 50mm to 100mm wider on all sides). This helps prevent water from pooling against the shed walls and provides a solid edge for anchoring.
