How long does concrete take to cure?
Concrete usually begins to set within a few hours, but curing takes much longer. In simple terms, setting is when the surface becomes firm, while curing is the process where concrete gains strength. For projects where early access is essential, Rapidset (also known as Rapidcrete) offers a faster-curing alternative, allowing vehicle traffic from approximately 48 hours after installation. This makes it an excellent solution for critical areas, emergency works and projects where minimising downtime is a priority.
When can you walk on concrete?
Light foot traffic is often possible after around 24 to 48 hours, depending on weather conditions, concrete mix and site conditions.

When can vehicles drive on it?
For cars and light vans, a longer period is normally required. For HGVs, plant machinery or industrial traffic, concrete needs sufficient curing time before being put under heavy load. As a guide, standard concrete typically reaches approximately 70% of its design strength after 7 days and around 90% after 28 days, while continuing to cure and harden for years thereafter.
Because of this, we generally recommend waiting at least 7 days before allowing heavy traffic onto newly installed concrete. The exact timeframe will depend on the concrete specification, weather conditions, slab thickness, reinforcement and the expected loading.
Where early access is critical, Rapidset (also known as Rapidcrete) provides a faster-curing alternative. Depending on the product used and site conditions, it can typically accommodate vehicle traffic from around 48 hours after installation, making it an excellent solution for emergency repairs, high-traffic commercial areas and projects where downtime needs to be kept to a minimum.
What affects curing time?
- Concrete depth and specification
- Weather conditions
- Ground preparation
- Vehicle weight and usage
- Reinforcement requirements
How thick should a concrete slab be?
The correct slab thickness depends on how the area will be used. A concrete slab for pedestrian use is very different from one designed for HGVs, commercial yards or industrial units.
Typical considerations
- Expected vehicle weight
- Frequency of traffic
- Ground conditions
- Drainage requirements
- Reinforcement specification
Why professional assessment matters
A slab that is too thin or poorly prepared can crack, move or fail under pressure. Hutchings can assess the site and recommend a suitable concrete specification based on the project requirements.
Do I need drainage before laying concrete?
Drainage should always be considered before concrete is installed, especially on commercial sites, yards, car parks and access roads. Poor drainage can lead to standing water, surface damage and long-term maintenance problems.
Common drainage issues
- Standing water after rainfall
- Poor falls across the surface
- Blocked or undersized drainage systems
- Water running towards buildings or entrances
How Hutchings can help
Hutchings can review the existing site levels, drainage routes and ground conditions before works begin. This helps ensure the finished concrete area is practical, durable and suitable for long-term use.
