Welwyn Garden City has a distinctive mix of 1920s and 1930s planned-town housing alongside newer residential and commercial developments. That variety shows up in the types of concrete jobs people need doing here, from shed bases and driveways in older residential streets to commercial floor slabs on the town’s business parks.
This guide covers what you need to know before ordering ready mix concrete in Welwyn Garden City.
Which Concrete Grade Do You Need?
The grade you order depends on what you are building. The table below covers the most common projects in the area and the mix typically recommended for each. For a more detailed explanation of how designated mix types such as GEN, PAV, and FND are defined, the Concrete Society’s Fingertips resource on mix design is a useful reference.
| Project type | Recommended grade | Notes |
|---|---|---|
| Shed base or small outbuilding | C20 / GEN3 | Standard domestic slab |
| Garage base | C25 / ST2 | Heavier loads from vehicles |
| Driveway | PAV1 | Air-entrained for frost resistance |
| Patio or garden path | PAV1 | Smooth finish, frost-resistant |
| Strip foundation | C25 or FND2 | FND2 where sulphate-bearing soil is a concern |
| Commercial floor slab | C30 or C35 | Depends on loading requirements |
If you are unsure which grade suits your job, the Base Concrete team will advise you before you order.
Lorry Options
Base Concrete offers two lorry sizes for Welwyn Garden City deliveries. Mini mix lorries are roughly the same size as a skip lorry, carry up to 4.5 cubic metres, and can reach tighter spots on older residential streets and rear gardens. Standard lorries carry up to 8 cubic metres and suit larger pours where access is straightforward.
If the lorry cannot get close enough to the pour, concrete pumping in Hatfield is available nearby. A pump runs pipes from the lorry on the road directly to the pour location, which removes most access problems.
Why Volumetric Delivery Works Well Here
Many Welwyn Garden City jobs are domestic projects where the exact volume is hard to pin down in advance. With volumetric concrete, the raw materials are carried separately and mixed on site at the point of delivery. You pay only for what is actually poured, with no waste from leftover concrete. The mix can also be adjusted between pours if your project needs more than one grade.
How Much Concrete Do You Need?
Multiply length by width by depth (all in metres) to get your volume in cubic metres. Add around 10% for uneven ground. Base Concrete’s concrete calculator lets you enter your dimensions for a quick estimate.
