Shed, garage and industrial slabs around Trafalgar

Every shed starts with the slab

Whether it is a single garage in a Trafalgar backyard, a big machinery shed on a Narracan farm or a workshop floor in a Moe or Morwell industrial estate, the slab sets how well the building performs. Get it level, square and strong, and the frame goes up easily, the doors seal, and the floor carries whatever you park or bolt to it. Get it wrong, and you fight it for as long as the shed stands.

Working to the shed engineering

Kit sheds and garages come with engineering that specifies the slab: thickness, edge beam or pier details, steel, and where hold-down bolts or brackets go. Larger buildings and industrial floors are designed by a structural engineer. We pour to those drawings, set out the slab to the exact dimensions the frame needs, and check diagonals so it is square. If the drawings call for cast-in bolts, we set them with templates before the pour.

Ground preparation

Shed slabs around Trafalgar are often in paddocks, on sloping backyards or on old farm tracks. We strip topsoil, cut and fill to create a level pad, compact crushed rock in layers, and make sure the finished floor sits above the surrounding ground so water flows away rather than into the shed. On a sloping block, that may mean a small retaining edge or a cut drain on the high side.

Garage and backyard shed slabs

For home garages and backyard sheds we pour a slab with a smooth trowelled finish that is easy to sweep, thickened edges where the frame needs them, and a slight fall toward the door. A separate apron in front of the roller door, falling away from the shed, stops rain blowing under the door. If you plan to use the space as a workshop, we can cast in conduits for power and allow for a car hoist.

Farm machinery and hay sheds

On farms around Darnum, Narracan and Thorpdale, machinery sheds carry tractors, harvesters, trucks and heavy implements. These slabs need more thickness and steel, generous aprons at the openings, and a broom or lightly textured finish where machines turn. Hay sheds benefit from a floor raised above the ground outside, with falls to keep water out from under bales.

Industrial and commercial floors

Workshops, warehouses, transport depots and engineering businesses in the Latrobe Valley need floors that carry forklifts, pallet racking and heavy vehicles. We pour these to engineering, with joint layouts that control cracking under heavy loads, steel or fibre reinforcement as specified, and finishes ranging from steel trowel and burnished to broom for external hardstands. We can stage pours so parts of an operating site stay usable.

Joints, curing and flatness

Large slabs shrink as they cure, and without control joints they will crack randomly. We plan saw-cut or tooled joints to suit the slab size and use, and cure the concrete properly so it reaches its design strength. For racking or machinery, we pay close attention to flatness during finishing.

Access and pour day

Shed sites are often at the back of a property or across a paddock. We check truck and pump access before quoting and may recommend a pump, a temporary track or pouring in sections. In winter, soft ground can stop trucks, so timing and access planning matter.

Permits

Most garages and larger sheds need a building permit, and the permit drawings usually include the slab engineering. Industrial work may also need planning approval. We work from the approved drawings and coordinate inspections.

Written quotes

Send us the shed drawings or engineering, and photos of the site. After a visit we provide a written, itemised quote for site preparation, base, steel, concrete, finish, aprons and clean-up.

Planning the slab around how the shed will be used

Before we quote a shed slab, we ask how the building will be used, because that changes more than the thickness. A workshop with a car hoist needs a thicker section and hold-down points where the hoist will stand. A shed storing machinery needs a hard-wearing surface and wide aprons. A shed housing animals or wash-down areas needs falls to a drain and a textured finish. A home gym or games room in a garage benefits from a vapour barrier and a smooth finish ready for floor coverings. Thinking about this early saves cutting into a new slab later.

Mezzanines, racking and point loads

Mezzanine floors, pallet racking, heavy benches and machines put concentrated loads on small areas of slab. These need to be allowed for in the engineering, with thickened sections or extra steel at post and leg positions. Tell us about any planned fit-out before the slab is designed, and we will make sure the engineer and the pour account for it.

Sheds on sloping farm sites

On hilly properties around Thorpdale, Narracan and Trafalgar South, finding a level spot for a big shed often means cutting into a slope. We plan the cut, the batter or retaining on the high side, a cut-off drain to stop water running down into the shed, and an apron and approach that machinery can climb easily.

Before you order the shed

It pays to confirm the slab details with the shed supplier before the kit is ordered or delivered: exact external dimensions, door positions and widths, the type of footing or edge beam, and the bracket or bolt layout. A slab that is a few centimetres out can make the frame difficult to erect.

Gippsland clay, river flats, red hill soil and two councils

Around Trafalgar the ground changes with the landscape. Town blocks and most new estates sit on yellow and grey clay that swells with winter rain and shrinks in a dry summer. The river flats hold softer silt that stays wet for weeks. South toward Trafalgar South and Thorpdale, the Strzelecki foothills bring deep red volcanic soil that drains freely but goes soft when saturated and scours on a slope. On clay we remove topsoil and soft material and build up compacted crushed rock in layers; on wet flats we may go deeper and lift the finished level; on hill soils we focus on edge support and stopping runoff before it undercuts the slab.

Work inside your boundary is usually permit-free. Crossovers, nature strips and public footpaths are road reserve, which needs consent from Baw Baw Shire for Trafalgar, Yarragon, Warragul, Drouin, Darnum, Thorpdale and Narracan, or Latrobe City for Moe, Newborough and Morwell. Rural entrances on main roads may also involve the state road authority, and slabs for houses, garages and large sheds need a building permit and engineering. We list whatever applies in the quote.

How a Trafalgar Concreting quote is put together

Every quote we send is in writing and itemised, so you can see where the effort goes. It sets out the measured area, any break-out of old concrete and disposal, the excavation depth, the crushed rock under the slab and how it will be compacted, the slab thickness and reinforcement, the finish and colour or stone blend, where the joints will run, drains and pits and where water ends up, any steps, edges or retaining, sealing, and any crossover, road authority or building permit work. Anything that changes the job on the day, such as pump hire for a back yard, a long barrow run or a paddock that needs a temporary track, is spelled out rather than left as a surprise.

We do not advertise a square-metre rate. A driveway on firm clay in a Trafalgar estate, the same driveway on soft Moe River silt, and one climbing a red-soil hill toward Thorpdale each need different preparation, and that is where much of the work sits. Seeing the block first means the quote reflects your job, not an average.
