How Much Does Bamboo Excavation Cost? Prices by Area for 2026

Our general cost guide covers every method of dealing with bamboo. This page is narrower: it is for people who already know they want the bamboo dug out and want to understand what that costs for a given area, and why two quotes for the same garden can differ so much. All figures are indicative 2026 prices for South Wales domestic work, exclude VAT, and assume a typical established running bamboo. Your quotation will be based on a survey, not on a table.

Excavation Cost by Area

Area of bamboo	Typical excavation depth	Approx. soil volume	Indicative cost range	Typical duration
5 m²	50–60cm	3 m³	£1,000 – £1,800	1 day
10 m²	50–60cm	6 m³	£1,500 – £2,500	1 day
20 m²	60cm	12 m³	£2,200 – £3,800	1–2 days
30 m²	60cm	18 m³	£3,000 – £5,000	2 days
50 m²	60–75cm	30–38 m³	£4,500 – £7,500	2–3 days
100 m²	60–90cm	60–90 m³	£8,000 – £15,000+	3–5 days

Two things to note. First, cost per square metre falls as area rises, because machine mobilisation and set-up are fixed whether you dig 5m² or 50m². Second, the "area of bamboo" that matters is the area of rhizome, not the area of canes. A 10m² stand of running bamboo commonly has rhizomes across 20–30m², and it is the larger figure that determines the dig.

What the Price Includes

A properly specified excavation quote should cover:

• Site survey and rhizome tracing to establish the true extent
• Cutting and removal of canes and foliage
• Machine and operator (usually a 1.5–3 tonne mini excavator for domestic access)
• Labour for hand-picking, edge work and around services
• Segregation of rhizome material and its removal to a permitted facility, with waste transfer note
• Either on-site screening of soil for reuse, or removal of contaminated soil and import of clean backfill
• Backfilling and compaction to a level finish
• Written guarantee where the site and method qualify, with an insurance-backed guarantee available on request

What it does not include — with us and with most specialists — is reinstatement of lawn, planting, paving, fencing or other finishes. We backfill to a level, ready for your landscaper. If a quote is much cheaper than others, check which of the items above have been left out.

Worked Example: 30m² of Running Bamboo

An illustrative example: a rear garden in Neath with a 4m by 3m stand of Phyllostachys against the back fence. Tracing shows rhizomes extending 2–3m into the lawn and along the fence line, giving a dig area of about 30m². Side access is 1.1m wide, enough for a 1.5-tonne machine.

• Machine, operator and two-person team for 2 days
• 18m³ of excavation to 60cm, screened on-site; around 4 tonnes of rhizome and reject material removed
• Screened soil returned; 2 tonnes of topsoil imported to make up the level
• Guarantee documentation issued on completion

Indicative total in the region of £3,500–£4,200 excluding VAT. Had the access been through the house only, or the soil unsuitable for screening, the same job would sit nearer the top of the 30m² range or above it.

Access

Access is the single biggest variable after area. The questions are: can a machine get to the bamboo, how large a machine, and how far does material have to be moved to reach a skip or grab lorry?

• Good access (driveway or side gate of 1m or more): standard mini excavator and dumper; costs as per the table.
• Restricted access (narrow side passage, steps, through a garage): micro excavator, slower working, more hand-barrowing. Expect 20–40% more.
• No machine access (terraced house, garden only reachable through the property): hand excavation or a machine craned over. Hand digging 30m² to 60cm is many days of labour and can double the cost; craning is a fixed additional charge that often works out cheaper on larger areas.

Depth and Density

Most running bamboo rhizomes sit in the top 15–60cm, and a 60cm dig is standard. Deeper excavation is needed where rhizomes have followed loose fill, old trenches or free-draining soils to 75–90cm. Every additional 15cm across a 30m² area is another 4.5m³ of soil to move, screen or dispose of. Density matters too: a long-established stand produces a solid mat of rhizome that has to be broken up and picked out, which is slower than a younger plant with discrete runners. Our guide on how deep bamboo roots grow explains what to expect on different soils.

Haulage and Disposal

Soil is heavy — roughly 1.5 tonnes per cubic metre — and disposal is charged by weight. Removing all 18m³ from a 30m² dig means around 27 tonnes leaving site, then a similar quantity of clean material coming in. On-site screening typically reduces the outbound load to the rhizome and reject fraction, often 15–25% of the total, which is why we screen wherever access allows. Distance to the nearest permitted facility, grab-lorry versus skip logistics and whether a road permit is needed for a skip all feed into this line. See how excavated bamboo is disposed of for the detail.

Backfill and Reinstatement

Backfill is included; reinstatement is not. If the soil is screened and returned, the make-up quantity is small. If all soil is removed, the full volume must be replaced with imported topsoil or a subsoil/topsoil combination, and that material cost is significant on larger areas. What you intend to do with the area afterwards also matters — a future patio needs a compacted sub-base rather than topsoil, and telling us that at survey stage avoids paying for material that is then dug out again.

Structures, Drains and Boundaries

Bamboo rarely sits conveniently in the middle of a lawn. Each of the following adds time and care, and therefore cost:

• Buildings and walls: hand excavation within the last metre, and sometimes a structural or surveyor's opinion before digging near footings — see can bamboo damage house foundations?
• Drains and services: locating, exposing by hand and working around live pipes and cables; occasionally a CCTV survey before and after — see can bamboo damage drains?
• Paving, decking and sheds: lifting and setting aside, or removing entirely, before the ground beneath can be dug
• Boundaries: rhizomes that continue into a neighbouring garden cannot be excavated without that neighbour's agreement; a root barrier along the boundary is often specified instead, at an additional per-metre cost
• Trees and retained planting: working around root systems you want to keep slows the dig

Excavation vs Herbicide on Cost

A herbicide programme is usually cheaper up front — often a third to a half of the equivalent excavation — but it takes two to three growing seasons, leaves dead rhizome in the ground, cannot be used where rhizomes are already in drains or against structures, and the land cannot be used or sold as "cleared" until it is complete. Excavation costs more, is finished in days, removes the material, and produces the documentation buyers and lenders prefer. Which is right depends on your timescale, budget and what the bamboo is threatening. The best way to kill bamboo permanently compares the methods in full.

Getting a Reliable Quote

A quote for excavation without a site visit is a guess. A reliable quote follows a survey that traces the rhizomes, measures the real area, checks access and identifies services and structures, and it will state:

• The area and depth being excavated
• Whether soil is screened and reused or removed and replaced
• Exactly what is and is not reinstated
• Waste handling and documentation
• The guarantee terms and any conditions
