Concrete is a must for almost every construction project. In the UK alone, millions of cubic metres are poured every year, keeping construction projects moving at pace. It’s no surprise people often search for tips on how to make concrete safely, correctly, and efficiently.
At Technic Concrete Pumping, we’ve helped hundreds of UK contractors across a range of industries build-out their projects, from garden footings to towering commercial buildings. Before the concrete pump even arrives, though, you need to understand the material itself. Let’s break it down.
What Is Concrete Made Of?
Concrete is a blend of cement, aggregates, and water – but the proportions and quality of each component change everything. Cement acts as the binder, while aggregates such as sand, gravel, or crushed stone add volume and structural strength. Water activates the cement, creating a chemical reaction that hardens the mix into the durable material we rely on for foundations, floors, patios, and driveways.
Most standard mixes follow a 1:2:3 ratio: one part cement, two parts sand, three parts aggregate. Too much water leads to weak, crumbly concrete; too little makes the mix unworkable. This balance is why ready-mix concrete remains the preferred choice for larger projects, and why concrete pumping hire is so common.
How to Make Concrete
Making concrete by hand is straightforward once you understand the method. You’ll need cement, sharp sand, aggregate, and clean water. Most professionals prefer to use a mechanical mixer, which ensures a more uniform blend, but hand mixing can still produce good results. Here is the step-by-step process for how to make concrete –
- Combine all dry materials in the mixer or wheelbarrow.
- Mix until the colour is completely even throughout.
- Slowly add water until the mixture becomes workable.
- Aim for a consistency that is smooth but firm enough to hold its shape without running.
- The mix should slump slightly when poured, but not collapse into a liquid state.
- This consistency is ideal for bases, footpaths, fence posts, and shed foundations.
On commercial sites, the process scales up dramatically. Instead of manually blending materials, contractors rely on ready-mix suppliers and pump operators to deliver fresh, consistent concrete. Pumping ensures fast placement with minimal labour, especially on larger pours or tricky sites with poor access.
How to Mix Concrete
Mixing concrete correctly is important to achieving long-lasting strength. Start with your dry mix: cement, sharp sand, and aggregate must be fully blended before water is added.
If using a cement mixer, allow it to rotate for at least a minute before gradually adding your water. The goal is a cohesive mix with no dry patches and no excess pooling water.
The mixing time matters too. Under-mixing creates weak spots; over-mixing can cause excess air to enter the batch, lowering strength. Most small batches reach the perfect consistency within two to three minutes.
For larger pours, professional ready-mix ensures uniformity and quality. Pumping this mix through a boom pump or ground line pump maintains that consistency right up to placement, preventing segregation and improving compaction.
How Much Concrete Do You Need?
Estimating your concrete volume correctly avoids delays, wasted materials, and uneven slabs. The formula is straightforward:
*Length × Width × Depth, converted into cubic metres.*
For example, a patio measuring 4m × 3m at a depth of 0.1m requires 1.2m³ of concrete.
But many projects aren’t perfectly shaped, which is why we provide a concrete volume calculator to simplify the process. It’s ideal for foundations, slabs, trenches, garden projects, and commercial bases.
Once you know your volume, you can book the right pump size too – whether that’s a compact 20m pump for domestic jobs or a 53m boom pump for large construction sites.
How Long Does Concrete Take to Dry?
Concrete doesn’t just “dry”, it cures, meaning it undergoes a chemical reaction that strengthens over time. You can usually walk on concrete after 24 to 48 hours, but full curing takes around 28 days. Temperature, humidity, and mix design all influence the timeline.
If you’re interested in a deeper breakdown of curing stages, we have an entire blog dedicated to How Long Concrete Takes to Dry, which explains early stage finishing, protective curing techniques, and tips for cold weather pours.
For most projects, the key is patience. Avoid loading slabs too soon, especially with vehicles or structures. Proper curing prevents cracking, surface dusting, and reduced strength, all of which are issues that can be costly to fix later.
Do You Need a Concrete Pump?
Once you know how to make concrete, the next question is how to place it efficiently. Pump hire is often the simplest solution. It speeds up pouring, reduces labour, and ensures precision. Concrete pumps are especially useful for sites with restricted access, multi-storey pours, or long distance runs where wheelbarrowing simply isn’t practical.
Technic Concrete Pumping’s fleet covers everything from domestic jobs to large-scale industrial projects. Their operators are CPCS-accredited, FORS Bronze compliant, and equipped with advanced Smartronic and ASC stability systems for safe, reliable pumping.
