DIY concrete does sound exciting to a DIY enthusiast and may genuinely work for small, low-stakes jobs. Example: think of a small garden path, a bird bath base, or filling a modest fence post hole for your house. For these jobs, bagging a few kilos of pre-mixed cement from a builder’s merchant, adding water, and working quickly is perfectly reasonable. The risks are low, the area is small, and even if the finish is expected to be low and rough, it is not the end of the world.

However, one must know that the moment your project grows to a full driveway, a house extension foundation, a concrete floor slab, or a patio in such a scenario, the DIY route becomes far more complicated. Getting the mix ratio wrong, ordering too much or too little, or having the concrete dry before you can finish pouring are all very real problems. And fixing mistakes in concrete is not easy on the pocket. In fact, it usually costs more to put right than it would have cost to get right the first time.

2. Is It Better to Do Concrete Work Yourself or Hire a Professional?

The honest answer is: it depends on the size and purpose of the job. For anything structural, such as foundations, footings, and ground floor slabs, hiring professional concrete services is always the right call. Structural concrete has to meet specific strength grades. Use the wrong mix, and you risk cracking, subsidence, or worse, a building that is not safe. At RKB Kent Concrete, we offer a range of concrete strengths tailored to the exact demands of your project. We do not guess. We get it right.

For decorative or non-structural garden projects, a confident DIYer with good preparation can manage a small job. But even here, the quality of the concrete you use matters. Using premium-grade ready-mix concrete rather than hand-mixed bags from a shop will always give you a better finish and longer-lasting result.

3. The Real Cost of DIY Concrete

Many homeowners choose DIY concrete because they believe it saves money. And on paper, it can look cheaper at first glance. But let us look at what you are actually paying for when you go DIY: bags of cement, aggregate, sand, mixer hire, tools, your time, and the risk of errors. If you over-order material, you pay for waste. If you under-order, the job stalls, and you lose time and money trying to source more concrete quickly.

With our volumetric concrete service at RKB Kent Concrete, you only pay for what you actually use. Our volumetric trucks mix the concrete fresh on your site, to the exact volume you need. There is no leftover waste and no shortage. It is a far more cost-controlled approach than DIY bagging, especially on any job larger than a metre or two.

4. How Much Does a Professional Concrete Contractor Cost in the UK?

This is one of the most searched questions when people are weighing up DIY concrete against professional concrete services, and rightly so. Costs vary depending on the type of mix, the volume required, the location, and the access to your site. At RKB Kent Concrete, we aim to beat any quotation. We also offer same-day and next-day delivery across Gravesend, Dartford, Kent, and surrounding areas, so you are not paying extra for urgency.

Our services include ready-mix concrete, volumetric concrete, on-site mixed concrete, concrete pumping, and screed. Pricing is competitive, transparent, and tailored to your specific project. You can use our free Concrete Volume Calculator on our website to get a quick estimate before you even call us. There are no hidden costs and no nasty surprises.

5. When Is Professional Concrete the Only Sensible Choice?

Let us be direct here. There are situations where doing it yourself is simply not advisable, no matter how capable you are with your hands. These include:

•       House foundations and footings — structural integrity depends on the right concrete grade and even placement
•       Large driveway or patio slabs — volume and finishing require professional-grade machinery
•       Hard-to-reach areas — our concrete pump hire service delivers concrete to awkward or elevated locations without wheelbarrows and without the mix drying out en route
•       Floor screed for kitchens, bathrooms or underfloor heating — screed is a fine mix of cement and sand that needs a perfectly level, smooth finish
•       Commercial and industrial projects — no room for error on large pours

Our concrete pump hire service, for example, is the safest and fastest way to get concrete exactly where you need it — no manual handling, no spills, no wasted mix. It is especially valuable on sites where access is limited or where the pour point is not easily reachable by a truck.

6. What Happens When DIY Goes Wrong?

We see it regularly. A homeowner attempts a DIY concrete driveway. The mix is too wet, it sets unevenly, and hairline cracks appear within a year. Now they need to break it all up, remove the waste, and start again — this time with professionals. The cost doubles. The stress is significant. And the time lost cannot be recovered. The pain point is not just financial. It is the frustration of doing a job twice, the embarrassment of a driveway that looks worse than the one you started with, and the very real risk of structural problems if it was a foundational pour.

Professional concrete services eliminate this risk entirely. At RKB Kent Concrete, every batch is produced under controlled conditions using premium-grade aggregate and cement. Consistency is guaranteed. Whether we deliver ready-mix concrete or mix it fresh on-site, every batch meets the same high standard. That is not something a hand-mixed bag from a builder’s merchant can promise.
