Key takeaways
- Most concrete work jobs in Singapore land between SGD 200–SGD 25,000 — known locally as concrete repair and screeding.
- In Singapore, spalling-concrete repair in older flats is routine — HDB requires registered renovation contractors for works in its flats, and structural alterations need BCA approval with a Professional Engineer. Screeding is the most common residential 'concrete' job.

What affects the price
- Job size and scope — bigger or more complex jobs move you up the ranges above.
- Access and condition — hard-to-reach areas, older properties or neglected maintenance add labour time.
- Materials and quality level — where materials are involved, the grade you choose often matters more than labour.
- Urgency — same-day or out-of-hours work usually carries a premium.
- Where you live — large metros in Singapore typically run above the national range; smaller towns below it.
How to save
- Get at least three quotes and compare like-for-like scopes, not just totals.
- Be flexible on timing — off-peak slots are often cheaper.
- Bundle related tasks into one visit to spread call-out costs.
- Agree the scope in writing up front to avoid change-order surprises.
How to hire a concrete work pro in Singapore
- For anything structural (hacking into or repairing structural elements), a BCA-registered contractor and possibly a Professional Engineer are required
- In HDB flats, floor screeding and minor concrete works must follow HDB renovation guidelines and use HDB-registered renovators
- Get scope in writing: area, thickness, mix or screed type, and curing time before flooring goes on
- For spalling concrete (common in older flats), ask whether the repair covers rust-treating exposed rebar, not just patching
- Confirm debris disposal is included
- Check track record with similar jobs
Red flags
- Patch-only fix proposed for ceiling spalling without treating corroded rebar
- Structural work offered without PE involvement
- No curing time allowed before floor finishes
- Full payment upfront

Frequently asked questions
How long does concrete take to cure?
You can usually walk on it after 24-48 hours, drive on it after about 7 days, and it reaches design strength at 28 days. Curing (keeping it damp, protecting from frost or extreme heat) in the first week matters more for durability than almost anything else.
Does weather affect concrete pouring?
Strongly. Frost can ruin an uncured pour, extreme heat causes plastic shrinkage cracking, and rain marks fresh surfaces. Good contractors watch forecasts and will delay a pour; be suspicious of anyone happy to pour into bad weather to keep the schedule.
Can damaged concrete be repaired instead of replaced?
Surface spalling, small cracks and pitting can be patched, resurfaced with an overlay, or ground back. Slabs that have sunk can sometimes be lifted with foam or grout injection ('slabjacking') for far less than replacement. Structural failure or widespread base movement means replacement.
How thick should a concrete slab be?
Common rules of thumb: 75-100mm (3-4") for paths and patios, 100-125mm (4-5") for driveways and garage floors, more for heavy vehicles — always over a compacted sub-base with mesh or fibre reinforcement. Thin slabs on soft ground crack no matter how good the finish looks.
What finishes can concrete have?
Broom (non-slip, standard outdoors), steel trowel (smooth, indoor), exposed aggregate, stamped/patterned, coloured and polished. Decorative finishes can add 30-100% to the base rate but replace the cost of a separate surface like pavers or tiles.
Who fixes spalling concrete in Singapore flats?
For HDB flats, engage an HDB-registered renovation contractor; the proper repair treats the corroded reinforcement bars and re-patches with bonding agents, not just plaster over the hole. HDB also runs assistance schemes for ceiling spalling in older blocks.
