TARMAC
Square metres of asphalt laid across Hong Kong since 2006
Average site downtime — we hand back the surface before business hours
Years operating in Hong Kong — through three typhoon seasons and two reclamations
Government contract renewal rate — the figure that matters most to procurement
Six phases.
No surprises.
Every engagement follows the same sequence. Below is exactly what happens, how long each phase takes, and what we need from you.
Survey
Our site engineer walks the surface with a 4-metre straight-edge, a depth gauge, and a thermal scanner. We map every crack, rut, and drainage fault — producing a condition report you can attach to your own maintenance file.
We record core samples at 25-metre intervals to determine existing layer thickness. The report specifies exact tonnage required, traffic management requirements, and confirms whether the sub-base needs remediation before overlay.
Quote
We return a fixed-price tender document — not a range, not an estimate. The price covers mobilisation, materials at current plant rates, traffic management, and post-lay inspection. No variation orders unless you change the scope.
The document references BS EN 13108-1 mix specifications and HKSAR Highways Department standard drawings. Procurement teams can attach it directly to their vendor approval process.
Mobilise
The night before laying, our crew pre-positions the placer machine, two steel-drum rollers, and the traffic management kit. Hot-mix is ordered from the plant for a 2:00 a.m. delivery — timed so we finish before the morning shift.
We coordinate with your security team on gate codes and emergency contact protocols. A crew foreman number is issued to your facilities manager for real-time updates throughout the operation.
Lay
The placer machine lays hot-mix at 150–160°C in a single continuous pass — no cold joints, no patchwork. The screed operator maintains a constant head of material so density is uniform across the full width.
Breakdown rolling starts within 60 seconds of laying to lock aggregate before the mix cools below 120°C. Intermediate and finish rolling follows the temperature curve, not the clock.
Cure
We do not hand back the surface until our thermal camera reads below 40°C across the full laid area. Cooling time varies with ambient temperature — in Hong Kong summers, we factor in humidity.
Light vehicle traffic is permitted at 40°C. Heavy goods vehicles and container trucks are held until 30°C — typically 30–45 minutes after light traffic release. Your foreman receives a WhatsApp confirmation with the thermal scan attached.
Inspect
Three days after laying, we return with the straight-edge. Any deviation greater than 3mm in 4 metres is remediated at our cost, no questions asked. We photograph every linear metre and append the images to your maintenance file.
The completion certificate records mix reference, layer thickness, compaction density, and surface regularity — the exact data your insurance underwriter and government inspectors require for asset registration.
Three sectors.
One standard.
"Tarmac resurfaced three of our Kowloon car parks in a single weekend. The surfaces were handed back before Monday morning — zero tenant complaints."
Henderson Land Development
Raymond Cheung, Facilities Director
"Their condition reports are formatted to our specification and their as-built records are complete on day one. Procurement teams re-tender with Tarmac as preferred vendor."
HKSAR Highways Department
Winnie Lau, Senior Engineer
"Our loading bays take forty-tonne containers daily. Tarmac specified a 100mm overlay with a modified binder — we have not had a rut failure in three years."
