How thick should a concrete slab be for a shed?
Shed slab thickness depends on the structure’s purpose and load requirements. For light storage sheds in Bundaberg, a 100mm (4-inch) slab with reinforcing mesh provides adequate support. Garages and workshops handling vehicles require 150mm (6-inch) thickness, while heavy equipment or farm sheds need 150-200mm slabs with enhanced reinforcement.
Recommended Thickness by Shed Type:
- Storage sheds: 100mm with SL72 mesh
- Garages and workshops: 150mm with SL82 mesh
- Farm sheds and heavy equipment: 150-200mm with engineered reinforcement
Bundaberg’s soil conditions, particularly in flood-prone areas, may require additional base preparation and drainage considerations. A professional site assessment makes sure your slab thickness matches soil type, intended load, and local climate factors. All shed slabs should comply with Australian Standard AS 2870 for residential footings and slabs.
Types of Shed Slabs We Install in Bundaberg
Every shed serves a different purpose, and the concrete base needs to match what you’re building. We install garage slabs Bundaberg residents use for everything from single-car garages to multi-bay workshops, and we make sure each one’s built to handle the specific loads it’ll carry.
Why Proper Shed Foundations Matter in Bundaberg
A shed’s only as good as what it sits on. Cut corners on the foundation and you’ll be dealing with problems from day one—cracks, uneven floors, water pooling, and structural issues that cost more to fix than doing it right the first time.
Protection Against Bundaberg’s Climate Conditions: Flooding rains, summer heat, and soil movement test foundations hard. Proper drainage, correct reinforcement, and base preparation handle Bundaberg’s specific climate challenges.
Long-Term Structural Stability: Properly installed slabs prevent settling, keep doors closing right, and maintain level surfaces. Correct thickness and reinforcement protect your shed’s structural integrity long-term.
Preventing Costly Repairs and Damage: Fixing failed slabs costs more than proper installation. Water damage, cracks, and structural issues add thousands in repairs that proper groundwork prevents completely.
Shed Slab Specifications and Requirements
Getting shed slabs right means following proper specifications and meeting Australian Standards. The details matter—wrong thickness, inadequate reinforcement, or poor drainage all create problems you’ll be fixing later.
Concrete Thickness and Reinforcement Standards: Standard storage sheds need 100mm slabs with SL72 mesh. Garages require 150mm thickness with SL82 mesh. Farm sheds handling heavy equipment need 150-200mm with engineered reinforcement matching load requirements.
Site Preparation and Drainage Considerations: Compacted roadbase 75-100mm thick provides a stable foundation. Properly directs water away from entries. Bundaberg’s soil conditions often need extra drainage solutions in flood-prone areas.
Council Approval and Compliance Requirements: Sheds over certain sizes need council approval. All slabs must comply with Australian Standard AS 2870. We handle documentation and make sure your slab meets Bundaberg Regional Council requirements.

Frequently Asked Questions About Shed Slabs in Bundaberg
Most shed slabs take 2-3 days from start to finish. Day one covers site preparation and formwork. Day two is the concrete pour. Then the slab needs seven days to cure before you can build on it. Weather and site conditions can affect timing—wet ground or difficult access adds time to preparation work.
It depends on your shed size and location. Sheds under 10 square metres typically don’t need approval. Anything larger usually does. We recommend checking with Bundaberg Regional Council before starting. We can help with documentation if approvals are required for your project.
Yes, but it requires more site preparation. We excavate and level the area, sometimes building up the low side or cutting into the high side. Sloping sites often need retaining walls or additional drainage work. We assess the slope during the site visit and factor costs into your quote.
Shed slabs are generally simpler—no plumbing penetrations, electrical conduits, or internal walls to work around. They’re usually thinner than house slabs unless you’re storing heavy equipment. The preparation and concrete quality standards are the same, just fewer complications during installation.
Costs vary based on size, thickness, site conditions, and access. A basic 3m x 3m storage shed slab starts around $1,500-$2,000. Standard single garage slabs (3m x 6m) run $3,000-$4,500. Larger or more complex jobs cost more. We provide detailed quotes after assessing your specific site and requirements.
Minor surface cracks are normal in concrete—they don’t affect structural integrity. Larger cracks indicate problems with base preparation, reinforcement, or soil movement. Properly installed slabs with correct thickness and reinforcement rarely develop serious cracking. We guarantee our workmanship, so if issues arise from installation faults, we fix them.
