Concrete: What You Need to Know for Strong, Long‑Lasting Builds

If you’re planning a renovation, a new kitchen, or a garden patio, chances are concrete will be part of the project. It’s cheap, strong, and works in almost any climate. Below we break down the key reasons people choose concrete, what to look for when buying, and easy steps to keep it in good shape.

Why Concrete Stands the Test of Time

Concrete gets its strength from a simple mix of cement, water, sand and gravel. When the mixture cures, it turns into a stone‑like mass that resists compression, fire and rot. That’s why you see it in foundations, driveways, and even modern kitchen countertops.

Compared with wood or plaster, concrete doesn’t warp or shrink with humidity changes. It also handles heavy loads, which makes it ideal for load‑bearing walls and floor slabs. In the UK, many new homes use concrete slabs because they settle slowly and predictably, reducing the risk of cracks later on.

Practical Tips for Using and Caring for Concrete

Choose the right mix. Not all concrete is the same. For driveways, a standard 20‑mm mix works well. For patios that need a smooth finish, ask for a finer grade. If you’re building a wall or a foundation, a higher‑strength mix (like M30) gives extra durability.

Watch the curing time. Concrete needs moisture to cure properly. Keep it damp for at least 7 days – a simple spray bottle or covering with a wet canvas does the trick. Rushing the process can lead to weak spots that later crack.

Seal it. A clear sealant protects against water penetration and stains, especially in wet areas like bathrooms or garden paths. Re‑apply the seal every 2‑3 years to keep the surface looking fresh.

Mind the expansion joints. Concrete expands and contracts with temperature changes. Adding joints every 3‑4 metres prevents random cracking. You can buy cheap joint strips at most hardware stores.

Repair cracks early. Small hairline cracks can be filled with a ready‑mix concrete filler. For larger gaps, clean the area, apply a bonding agent, then fill with a fresh concrete mix. This stops water from sneaking in and causing larger damage.

When it comes to foundation work, concrete is the backbone. If you suspect settling – like doors sticking or uneven floors – a professional can test the slab. Most new builds settle within the first year; after that, movement slows down dramatically.

Remember, concrete isn’t a set‑and‑forget material. Regular cleaning, resealing, and checking for early cracks keep it performing for decades. Whether you’re laying a new driveway, installing a kitchen countertop, or reinforcing a foundation, these simple steps will help you get the most out of concrete.
