Foundation and concrete work in Hong Kong: quotes and rules
Foundation and concrete work in Hong Kong is priced per job after the site is measured, but the published reference for concrete patch repair is HK$640 to HK$2,150 per square metre (approximately, according to a building cost reference, November 2026). A new base or footing needs its dimensions and soil conditions first, so a request with those details gets a more useful quote. The quickest route to current offers is a request on BlaBlaPrice.
What the price depends on
- the work needed: a new base, a slab, footings or a patch repair
- dimensions or volume, in square metres and cubic metres
- soil and plot conditions, which a site visit confirms
- whether the contractor supplies the concrete and the reinforcement
- site access, which is tighter in dense districts such as Central and Kowloon
- the deadline and your budget
Quotes are per job, in HK$, and a contractor usually needs the dimensions before giving a figure.
Rules, registration and permits
Construction workers in Hong Kong need worker registration with the Construction Industry Council, which handles applications through its app, so ask the contractor to confirm that everyone on site is registered. Projects involving building, civil or foundation works may need environmental permits, and the developer, architect, engineer or contractor involved is the party that applies. Foundation design follows the Buildings Department's Code of Practice for Foundations (2024 edition), which is written for local use. Copies of certified building plans cost HK$93 per sheet, which is useful when you check an existing building's records.
Season and weather
Winter, from December to February, is cooler and drier, which suits pouring concrete and patch repairs, because concrete sets more slowly in cool weather. Summer, from June to August, is hot and humid, so schedule pours early in the day and ask the contractor how they protect fresh concrete from drying too fast. Start in a dry spell so the surface has time to cure.
What to put in the request
Say whether you need a new base, a slab, footings or a patch repair, and give the dimensions and volume if you know them. Add the soil or plot details you have, the site address with its district, whether the contractor supplies concrete and reinforcement, the deadline and your budget in HK$. Photos of the existing surface help a contractor price a repair before a visit.
On BlaBlaPrice the request is free for buyers. Describe the job in your own words in a chat, add a photo if you like, and BlaBlaPrice's AI asks for missing details, looks through local price lists and shows the prices and businesses it found. Registered sellers reply with their own offer, price and terms, and your contact details stay hidden until you choose whom to contact. Related work is under construction and renovation, and you can also see construction services.
