Area
The overall size of the driveway is typically one of the biggest factors, as it drives the amount of concrete, base material and labour.
Finish
Plain concrete is generally the most economical. Exposed aggregate and coloured concrete usually cost more due to extra materials and labour, such as decorative stone, pigment, washing back and sealing.
Removal and disposal
If there's an existing driveway, breaking it up, loading it and disposing of it adds work. The type of surface and how much there is both matter.
Excavation and base
Levelling the ground and preparing a compacted base is commonly needed, and Perth's sandy soils can call for extra preparation.
Access
Tight side access, steep approaches or limited room for trucks and pumps can affect how the job is done.
Slope and drainage
Sloping blocks may need extra formwork or steps, and drainage may need to be addressed so water runs away from the home.
Crossover and council requirements
Including the verge crossover adds area and may involve meeting your council's specifications and approval process.
Reinforcement and thickness
Mesh, slab thickness and joint layout are typically chosen for the expected loads. Heavier vehicles may call for a more robust slab.
Sealing
Sealing is commonly recommended for decorative finishes and is sometimes optional for plain concrete.
