What is concreting?

Concreting is the process of mixing, pouring, levelling, and finishing concrete to create a strong, durable surface or structure.

Contractors combine cement, water, aggregates, and additives to produce concrete that’s suitable for your project’s strength and load requirements.

Signs you might need a concreting contractor

• You’re planning a new slab, foundation, base, driveway, or patio
• Your existing concrete is cracked, uneven, or sinking
• You’re building an extension or outbuilding that needs a structural base
• You want a decorative or polished concrete finish
• You need heavy-duty concrete for a garage or commercial space

How much does concreting cost?

Concreting tends to cost between [pricing[1].London.[Concrete Pouring].[lowPriceFormatted]] and [pricing[1].London.[Concrete Pouring].[highPriceFormatted]], with average concreting costs around [pricing[1].London.[Concrete Pouring].[averagePriceFormatted]].

Typical factors that can affect the cost of concreting:

• Concrete grade and strength required
• Volume of concrete (measured in m³)
• Site access and equipment needed
• Ground preparation or excavation
• Labour time and finish (basic, smooth, patterned)
• Any reinforcement (mesh or rebar)
• Weather conditions affecting curing

Types of concrete (and when to use them)

• PCC (Plain Cement Concrete): Best for non-structural work such as pathways or simple bases
• RCC (Reinforced Cement Concrete): Includes steel reinforcement for structural loads (foundations, beams, slabs)
• Ready-mix concrete: Factory-mixed for consistency, ideal for larger pours
• On-site mixed concrete: Good for smaller jobs or where flexibility is needed
• High-strength grades (C30, C40, C45): Used for heavy-duty applications such as driveways and industrial floors
• Lower grades (C8, C10, C15): Suitable for kerbs, footings, and simple domestic work

Concreting vs DIY concrete mixing

Hiring a concreting contractor

• Ensures correct concrete grade
• Avoids cracks, weak spots, and uneven curing
• Achieves a smooth, level finish
• Uses specialist tools for pouring and screeding
• Faster and safer for large volumes

DIY concreting risks

• Incorrect mix ratios weakening the structure
• Poor ground preparation leading to sinking
• Inconsistent finish
• Concrete setting before work is complete
• Increased injury risk due to weight and speed required

What is the process of concreting?

A typical concreting job includes:

• Ground preparation: Clear debris, level the area, add a compacted sub-base
• Formwork creation: Timber or metal forms define the shape and hold the concrete in place
• Mixing concrete: Using the correct ratio of cement, sand, gravel, and water
• Pouring: Concrete is poured into the forms quickly to avoid premature setting
• Screeding: Levels the surface and removes excess material
• Floating: Smooths the concrete and compacts the surface
• Adding joints: Reduces cracking by controlling where the slab can expand
• Finishing: Brushed, smooth, or decorative finishes applied as needed
• Curing: Concrete must be left to cure for around 28 days before full strength is achieved

How long does concreting take?

• Ground preparation: 1–2 days depending on complexity
• Pouring and finishing: A few hours for most domestic slabs
• Initial set time: 24–48 hours before light foot traffic
• Full cure: 28 days to reach full strength

Your contractor will advise expected timelines for your specific project.

How long does concrete last?

Well-mixed, correctly cured concrete can last 50+ years, depending on:

• Weather exposure
• Freeze-thaw cycles
• Quality of materials
• Drainage conditions
• Reinforcement used
• Ongoing maintenance

Maintenance of concrete surfaces

• Apply a concrete sealer every 2–5 years
• Fix small cracks early to prevent spreading
• Keep drainage clear around slabs
• Clean surfaces to remove moss or algae
• Avoid heavy loads on thin or low-grade concrete

What should be included in your concreting quote?

When comparing concreting quotes in London, look for:

• Concrete grade and volume needed
• Sub-base and ground preparation costs
• Labour time and number of installers
• Equipment or pump hire
• Reinforcement (mesh or rebar)
• Finishes (smooth, brushed, patterned)
• Waste removal
• Timescales and curing advice

Clear, itemised quotes help you compare contractors fairly.

Common mistakes to avoid when concreting

• Using the wrong concrete grade for the job
• Pouring on poorly prepared ground
• Adding too much water (weakens final strength)
• Not using joints to prevent cracking
• Pouring concrete in poor weather without protection
• Skipping the curing stage
