When you’re starting a building or DIY project, one of the first questions that comes up is: what kind of concrete do I actually need? At GB Concrete & Pump, we get it, there are a lot of options, and it can be confusing if you’re not in the industry. That’s why we offer expert guidance, on-site concrete pumping, and volumetric concrete solutions to get your project moving efficiently.

Let’s Talk Concrete Grades: C15 to C40

Concrete grades are basically a way to measure how strong the concrete is after it’s had time to set (28 days, to be exact). The higher the number, the stronger the mix. Here’s a quick breakdown:

C15 Concrete

• Strength: 15 N/mm²
• Best for: Light domestic work like pathways, patios, and those initial blinding layers.
• Keep in mind: This one isn’t meant for anything structural.

C20 Concrete

• Strength: 20 N/mm²
• Best for: Home foundations, floors, and garage bases.
• Why choose it: Strong enough for most everyday projects around the house.

C25 Concrete

• Strength: 25 N/mm²
• Best for: Reinforced bases, trench fill foundations, and light commercial jobs.
• Versatility: It’s a solid choice for both homes and smaller commercial sites.

C30 Concrete

• Strength: 30 N/mm²
• Best for: Driveways, roadways, and medium-duty floors.
• Bonus: Stands up well to the elements and harsh chemicals.

C35 Concrete

• Strength: 35 N/mm²
• Best for: Structural work like beams, columns, and reinforced slabs.
• Tough stuff: Great for farms, factories, or anywhere that needs extra durability.

C40 Concrete

• Strength: 40 N/mm²
• Best for: Big commercial jobs—think highways, heavy-duty foundations, and large-scale infrastructure.
• Heavy-duty: This is the go-to when strength really matters.

And What About Screed?

While concrete forms your foundation, screed gives you that final, smooth layer. It’s a mix of cement and sharp sand that’s applied on top of a concrete base.

Why Use Screed?

• To level out floors before laying tiles, wood, carpet, or any other finish.
• To create a smooth, even surface.
• To cover underfloor heating pipes and help spread the warmth evenly.

There are a couple of types to choose from:

• Traditional Screed: Mixed on-site and takes a bit longer to dry.
• Liquid Screed: Flows easily, self-levels, and dries quicker.

Still Not Sure?

No worries, we’re here to help. At GB Concrete & Pump, we provide tailored advice, high-quality concrete mixes, and fast delivery and pumping services, including volumetric concrete for custom on-site adjustments.

Whether it’s a simple garden path, reinforced slab, or large-scale commercial job, we can supply the exact mix you need and get it placed efficiently.

Contact us today to book your concrete delivery, arrange on-site pumping, or discuss volumetric concrete solutions for your project. Let’s get your concrete poured, pumped, and built to last.

When it comes to concrete supply, not all solutions are created equal. At GB Concrete & Pump, we specialise in volumetric concrete and for good reason. While traditional ready mix concrete has been the go-to option for decades, volumetric concrete offers a smarter, more efficient, and cost-effective alternative.

What’s the Difference?

• Ready Mix Concrete is batched at a central plant and delivered in rotating drum trucks. Once it’s on the road, the clock starts ticking – any delay can result in wasted product and extra costs.
• Volumetric Concrete, on the other hand, is mixed on-site using specialised trucks. Each ingredient is stored separately and combined only when and as needed.

Why Volumetric Concrete Wins

1. No Waste – You Only Pay for What You Use

One of the biggest advantages of volumetric concrete is zero waste. With ready mix, if you over-order, you’ll likely have excess concrete that can’t be used and you’ll pay to dispose of it. Under-order, and you’re stuck waiting for another batch to arrive, causing project delays.

With GB Concrete & Pump’s volumetric service, we mix exactly what you need on-site. No guesswork. No surplus. No paying for concrete that gets sent back.

2. Flexibility on the Job

Conditions on-site can change fast. Whether you suddenly need more or less material, volumetric trucks adapt in real time. This flexibility simply isn’t possible with ready mix, where once it’s batched, the ratio is fixed.

3. Fresh Mix, Every Time

Because volumetric concrete is mixed on-site, it’s always fresh. This means better quality and performance for your pour, compared to ready mix which may sit in a drum for hours before it arrives.

4. Environmentally Friendly

Less waste means a smaller environmental footprint. With volumetric concrete, you’re only producing what’s required, reducing the amount of raw material used and minimising unnecessary transportation.

Why GB Concrete & Pump?

At GB Concrete & Pump, we’re committed to delivering the most efficient and cost-effective concrete solution for your project. Our volumetric fleet ensures you receive the highest quality mix, with total flexibility and no hidden costs.

Let’s be honest, summer is a great time to get concrete work done, but it also comes with a few quirks. Hot weather, fast drying times and surprise rainstorms can all mess with a good pour if you’re not prepared.

As one of the leading concrete suppliers in the West Midlands, providing everything from volumetric concrete solutions to on-site concrete pumping, we’ve seen what happens when summer concrete goes wrong and we’ve built our entire process to make sure that doesn’t happen to you.

Whether you’re planning a new driveway, patio, or foundation, here’s what you need to know about the most common summer concrete problems and how we keep things running smoothly.

1. Concrete Cracking Too Soon (aka the “spiderweb surprise”)

The problem:

In hot, dry weather, concrete can dry too fast. That quick surface drying leads to shrinkage cracks and while some cracking is normal, too much of it (especially too early) is a red flag.

How we prevent it:

We adjust the mix, schedule precise deliveries, and, when needed, use on-site pumping to ensure the concrete is placed quickly and evenly – all to prevent those dreaded early cracks. Our team keeps an eye on weather conditions and uses water-reducing agents, curing compounds, or even shade if needed. It’s not just about pouring, it’s about managing that concrete every step of the way.

2. Curing Too Fast in the Heat

The problem:

Concrete needs time to cure slowly so it can reach its full strength. If it dries out too fast, it gets weaker and no one wants a flimsy slab.

How we prevent it:

With our volumetric concrete systems, we can tailor the mix on-site, giving us more flexibility to adjust water content and additives for optimal curing, even under scorching sun. We also use proper curing techniques like keeping the surface moist, covering it with blankets or plastic, or applying a curing compound. It’s like sunscreen for your concrete, a little protection goes a long way.

3. Surface Scaling or Dusting

The problem:

When concrete sets too fast or isn’t finished correctly in hot weather, the surface can flake or powder. That means your driveway or patio might look fine at first… until it starts wearing down.

How we prevent it:

Whether we’re delivering with our fleet or pumping directly into hard-to-reach areas, careful placement and timing help us avoid surface scaling and dusting. Timing is everything with concrete, and our crew knows exactly when to trowel, broom, or float for a strong surface that lasts.

4. Surprise Summer Showers (a classic)

The problem:

You’d think it’d be easy to avoid rain in the summer – but we’ve all seen the forecast change five minutes after a pour starts. Rain on fresh concrete can cause pitting, uneven textures, and even weaken the top layer.

How we prevent it:

We always check and double-check the forecast. And if there’s any chance of rain, we’re ready with tarps, covers, and quick communication to pause or protect the pour. Our concrete pumping service means we can cover large areas quickly if the weather suddenly changes – less exposure, less risk. If it’s not the right time to pour, we wait – simple as that.

5. Concrete “Burns” (Overworking in the Heat)

The problem:

Finishing concrete too soon or overworking the surface in hot conditions can trap water and ruin the finish especially if the top dries before the rest of it settles.

How we prevent it:

This comes down to experience. Using volumetric mixing and on-site pumping, we control exactly when and how the concrete hits the slab, reducing the risk of overworked surfaces in hot conditions. Our team knows how to read the slab, not just the clock. We pace the job to the conditions not the other way around.

You Deserve Concrete That Lasts, Even in Summer

Here’s the bottom line: concrete is a long-term investment. Whether it’s holding up your house, your driveway, or your new patio, you want it done right, especially when the sun is blazing and time is tight.

At GB Concrete & Pump, we’ve spent years learning how to work with the summer, not against it. We know what to watch for, what to adjust, and how to make sure your project looks great and holds strong for years to come.

Let’s build something solid this summer. No cracks, no surprises. Get in touch with GB Concrete to find out how we can make that happen for you.

Summer is fast approaching, the hard hats are on and for good reason. Summer is prime time for concrete projects, whether you’re laying the foundation for a dream home, pouring a new patio, or upgrading a commercial site. At GB Concrete & Pump, we’ve been around enough summers to know: if you want strong, lasting results, now’s the time to pour.

Here’s why summer and concrete go together like peanut butter and jelly (or, if you’re on-site with us, like coffee and early mornings).

1. Perfect Weather for Pouring and Curing

Concrete loves consistency and summer delivers. Warm temperatures and steady dry days create ideal conditions for pouring and curing concrete properly. When the weather behaves, so does the concrete.

In colder seasons, you’re battling rain, frost, and every contractor’s favourite word: “delays.” But in summer? We can pour, set, and cure concrete efficiently, helping your project move forward without unnecessary hiccups.

For planned foundations, patios and flatwork, ready mix concrete provides a consistent supply for pours of different sizes.

Quick Tip: While a little heat is good, a concrete pour during a heatwave isn’t a walk in the park (for us or your slab). Our team carefully times pours and uses techniques to prevent premature drying, so your project stays on track and crack-free.

2. Longer Days = Faster Progress

Summer’s extra daylight hours are more than just an excuse for a post-work barbecue. They allow our team to maximise work windows, keeping projects on schedule and clients smiling.

More daylight means:

• More flexible scheduling
• Fewer weather-related interruptions
• Quicker turnaround times

When we say we’ll show up and get it done, we mean it and summer makes that promise a lot easier to keep.

3. Ideal Timing for Autumn Move-Ins and Business Openings

Thinking about hosting a big backyard bash in Summer/Autumn? Opening a new shop before the holiday rush? You’ll want your concrete work completed now – not when the first frost sneaks up and everyone’s scrambling to winterise.

Concrete isn’t just about pouring; it’s about giving it proper time to cure and strengthen. Starting your project in the sunshine ensures it’s ready for whatever life (or your in-laws) throws at it come Autumn.

Reality check: Good concrete work takes more than a weekend and a prayer. Let’s get started early so your project isn’t fighting the clock.

4. Better Ground Conditions = Easier Site Prep

Summer doesn’t just help what’s above ground, it also makes everything underfoot a whole lot easier too. Dry, stable soil means better excavation, faster form setting, and fewer surprise costs when heavy equipment hits the site.

Translation? Your project runs smoother, faster, and more affordably. And you can spend less time worrying about mud and more time planning your next big move.

Concrete may be rock-solid, but even the toughest surfaces can crack under pressure—literally. Whether it’s your driveway looking like a roadmap of tiny motorways or a patio that’s more crumble than concrete, you might be wondering: should I repair or replace damaged concrete?

Well, let’s cement the facts and break it down (not like your concrete did, though).

Crack Me Up… Or Not?

Small cracks? No big deal. Concrete’s got a tough life – weather, moisture, wear and tear. Minor surface cracks are usually nothing to lose sleep (or slabs) over. These can often be patched up quickly and affordably, like giving your concrete a little facelift.

If you’re using volumetric concrete or on-site concrete pumping, even small repairs can be done efficiently, ensuring the fix blends seamlessly with the rest of your slab.

But if those cracks are wide enough to fit a slice of pizza in (okay, maybe a breadstick), you may be dealing with structural issues that need more than a surface fix. When cracks go deep, it might be time to break up (pun very much intended) with your current concrete.

The Ugly Truth About Spalling and Scaling

If your concrete surface looks like it’s been attacked by a pack of concrete-eating squirrels (read: flaky, peeling, or chipping), that’s called spalling or scaling. While some surface-level damage can be resurfaced, too much of it is a sign your concrete’s past its prime.

Using volumetric concrete, we can tailor replacements on-site to match your existing slab, giving your driveway or patio a seamless finish even when extensive spalling means a full replacement is needed.

Sinking Feeling?

If your slab has settled like a sponge cake, you’ve got a sunken concrete problem. Minor sinking might be fixable with levelling, but major dips could mean bigger issues below the surface – like soil erosion or poor prep work.

In those cases, replacing might be the solid move. Concrete pumping can help us get new concrete into tricky spots, making even a sunken slab manageable. Better to lift your spirits and your slab.

So… Should I Repair or Replace Damaged Concrete?

Here’s a quick guide to help:

Problem	Repair	Replace
Small, surface cracks	✅	❌
Deep or wide cracks	❌	✅
Minor surface flaking	✅	❌
Extensive spalling/scaling	❌	✅
Slight unevenness	✅	❌
Major sinking or heaving	❌	✅

If you’re not sure whether you’re dealing with a crack-up or a full concrete catastrophe, don’t worry—we’re here to pave the way.

Still Not Sure? Let’s Talk.

At GB Concrete & Pump, we’ve seen it all. Cracks, chips, dips, and everything in between. Whether you need a quick patch or a full-on slab swap, we’ll give it to you straight (and level).

So if you’re asking yourself, “Should I repair or replace damaged concrete?”—don’t go it alone. Give us a call, and let’s lay the groundwork for a solid solution.

A new analysis of Companies House data reveals that nearly 39.9% of newly established building development and house building companies in the UK have closed within five years.

The study, conducted by GB Concrete & Pump, highlights the significant challenges facing the sector amid volatile market conditions and the risks for companies attempting to establish themselves in construction.

High Failure Rates in the Building Development Sector

The study, covering company data from January 2019 to December 2023, looked at incorporation records across key segments of the building development industry. By tracking companies that have entered administration, liquidation, or dissolution, the findings paint a clear picture of survival rates across several building sub-sectors.

Across all categories examined, a striking 41.1% of new companies have ceased operations. However, the closure rates vary significantly across different construction segments, indicating unique pressures faced within each sub-sector:

Demolition
Closure rates are highest in demolition, where 56.3% of new firms fail – making it the most volatile and capital-intensive segment.

Site Preparation
46.6% of site preparation firms have closed, reflecting high costs and operational complexity.

Construction of Commercial Buildings
45.7% of commercial construction companies have ceased trading, underlining the competitive nature of the sector.

Domestic Building Construction
43.8% of domestic building firms have closed, showing that even housing-focused businesses face significant risk.

Building Project Development
This segment shows greater resilience, with a lower closure rate of 33.9%.

The Takeaway

The recent Labour budget announcement has introduced a potential lifeline for small housebuilders, promising an additional £3bn in guarantees. However, industry experts caution that the measures may come too late for companies already struggling under economic pressures.

Commenting on the findings, our spokesperson for GB Concrete & Pump, Director Vinny Singh said: “Our analysis reveals the reality of operating within the building development and housebuilding sector. With nearly half of new companies struggling to stay open, it’s essential for newcomers to recognise the challenges and strategically plan to improve their odds of long-term success.

The high closure rate of new businesses could potentially impact the overall growth and innovation within the sector. Fewer new entrants could lead to a less dynamic and competitive market, potentially affecting the supply of new homes and commercial buildings.

Although Labour has confirmed an additional £3bn in guarantees to support small house builders, it may already be too late for firms already struggling to afloat. Not to mention, it is not yet clear how this support will be allocated.”
