Slabs For Your Workspace

A shed slab needs to do more than look neat, it needs to handle weight, movement and constant use without becoming a problem later. At JDC Concreting, we build shed slabs across Grafton with a strong focus on how the space will actually be used. Whether it’s for vehicles, machinery, storage or a workshop setup, we plan slab thickness, reinforcement and levels to suit the load from day one. We also factor in drainage and access so water runoff and entry points don’t cause issues over time. Our approach is practical and considered, helping property owners avoid cracking, movement or uneven surfaces that can limit how a shed is used.


A properly built shed slab makes the rest of the structure work as it should. Call us on 0499 869 093 to discuss your shed slab requirements and organise a clear quote.

Frequently Asked Questions

  • How does slab thickness affect sheds used for vehicles or machinery?

    Shed slabs often carry heavier loads than residential concrete, especially where vehicles, trailers or machinery are stored. Slab thickness and reinforcement need to match the expected weight and movement. Undersized slabs can crack or flex under load, particularly near entry points. Designing for actual use helps prevent structural issues and surface damage.

  • Why do shed slab entry points crack more often than other areas?

    The entry point of a shed slab experiences repeated stress from vehicle tyres turning, braking and accelerating. Without additional reinforcement or thickening at this location, cracking is more likely to occur. Poor edge support can also contribute to breakdown over time. Strengthening these areas helps extend the slab’s usable life.

  • What happens if a shed slab is poured without allowance for internal drainage?

    Many sheds are exposed to water from rain, wash-downs or equipment cleaning. If the slab is completely flat, water can pool inside and create slip hazards or moisture issues. Small design falls or drainage points help manage runoff. Ignoring drainage can limit how the shed can be safely used.

Make Short Work Of Hard Work

Our shed slab services suit residential, rural and semi-rural properties where durability matters. We construct slabs for garages, workshops and farm sheds, taking into account vehicle access, equipment loads and site conditions. Each slab is prepared carefully to ensure a stable base, accurate levels and long-term performance. We understand that sheds are often installed quickly once the slab is complete, so timing and coordination are handled with care. By focusing on strength and usability, we deliver shed slabs that support how the space will be used every day.
