Volumetric Concrete Delivery in Harpenden
Custom Concrete uses volumetric trucks to transport raw concrete ingredients to your site. Once in place we mix on site concrete fresh for your requirements. Our lorries are 10 metres long, 2.5 metres wide and 4 metres high. They have an excellent reach but not all sites allow for easy access to the pour. If you need to pour from above, or you need more access, we provide boom and line pump hire for your convenience.

Harpenden Concrete Pour - FAQs
With over 20 years’ experience delivering concrete across Hertfordshire and nearby areas, the Custom Concrete team provides clear, practical advice to help your pour go smoothly. Below are the most common questions from customers in Harpenden ahead of their concrete delivery.
Your site should have firm, level ground and enough room for our vehicle to access safely. Our 8-wheel volumetric concrete lorries are approximately 10 metres long and 2.5 metres wide. If access is tight – for instance, narrow roads, alleys, or restricted driveways – our concrete pump hire service can make placement easier while minimising disruption and mess.
Yes. Volumetric concrete is mixed on-site, so our operators can alter the strength, workability, or consistency during the pour. This is useful if weather conditions change or different areas of your project need different mixes. You only pay for what you use – no waste, no leftovers.
Concrete sets quickly but requires time to cure properly. Light foot traffic is generally possible after 24–48 hours, while heavier loads or building work should wait at least 7 days. Full strength is typically reached after 28 days, so plan your schedule accordingly.
Absolutely. With no minimum order charges, we’re perfect for smaller jobs like patio slabs, shed bases, fence posts, and garden paths. Our volumetric trucks mix concrete on your driveway, so you get exactly what you need with the same quality as larger commercial projects.
Light rain is usually fine, but heavy rain can affect the mix if not managed. Our drivers can adjust the concrete on-site to maintain strength and durability.
