Which excavator is suitable for a house foundation?

The choice of machine depends on three factors: foundation depth, site access and volume of soil.

Indicative recommendation

Type of workRecommended machineDigging depthRate/day
Single or two-storey house foundation, narrow accessHitachi ZX48U-6 mini excavator (5.1 t)3.63 mRON 800
Foundation with basement, open siteHitachi ZX170W-6 wheeled (19 t)5.83 mRON 1,200
Deep foundation, large volumeHitachi ZX210-6 (24 t)6.67 mRON 2,200

When the mini excavator is sufficient

The 5-tonne mini excavator passes through a 2 m gate, does not damage yard paving and completes a house foundation in 2–3 days. It is the right machine for most individual homes.

When a larger machine is needed

We recommend a machine of 19 tonnes or more if the excavation is deeper than 2.5 m, the volume of soil exceeds 300 m³, the ground is hard clay or compacted gravel, or the soil must be loaded directly into a dump truck.

For an exact recommendation, contact us on +40 744 66 77 33 with the foundation dimensions.

💡 For a single-storey or two-storey house, the 5.1 t mini excavator, with a digging depth of up to 3.63 m, is usually sufficient. For a basement or foundations deeper than 2.5 m, we recommend a 19–24 t excavator.
