You are standing in a builders’ merchant with a weekend fencing project ahead of you, and the choice comes down to a bag of postcrete or a load of ready mix. Postcrete sets in minutes with no mixing required. That speed is what makes it practical for quick post installations. Concrete takes days to cure,

It depends on the size of your project. That is the honest answer most comparisons avoid giving. A bag of premixed concrete from a builders’ merchant costs around £7 to £10. Buying raw ingredients separately, cement, sand, and aggregate, brings that figure down to roughly £5 to £6 per bag equivalent. On paper, DIY mixing

Concrete slabs expand in heat and contract in cold. Without a designated space for that movement, the pressure builds up inside the slab until it cracks. A concrete slab expansion joint is the engineered solution that prevents this from happening, and understanding how it works is essential for any construction project involving concrete in the

Concrete roads in Epsom often crack due to ground and weather conditions. The local clay soils, Surrey’s temperature swings and heavy traffic all put pressure on roads from the day they are laid. Left untreated, a small crack spreads quickly, and repair costs grow fast. The good news is that most cracking is preventable when

Most problems on pour day don’t happen because of the concrete. They happen because the site wasn’t ready. A mixer truck weighing up to 32 tonnes won’t wait around, and concrete starts setting as soon as it leaves the plant. The good news is that most issues are completely preventable. A bit of planning beforehand

  Your builder scheduled the concrete pour for a crisp autumn morning, but temperatures dropped overnight. Now the slab refuses to harden whilst the forecast shows more cold weather ahead. The team has been waiting for hours, and everyone is wondering if the concrete will ever set properly. Cold weather changes everything about concrete work.

Ordering foundation concrete requires knowing exactly how many cubic metres you need to fill your trenches properly. Running low can stall the job mid-pour, creating vulnerable seams where fresh material meets portions that have already begun to cure. Overestimating brings its own issues, as surplus mix sits unused and hardens, driving up unnecessary costs. Calculating

The driveway you had installed last summer now has cracks running through it. Your patio, which looked perfect for months, has started splitting at random angles. Meanwhile, the garage floor heaves in one corner whilst a gap opens in another. These problems share a common cause: improper or missing expansion joints. Concrete expands and contracts

C20 concrete achieves 20 N/mm² compressive strength after 28 days, placing it at the point where light domestic work ends and genuine load-bearing construction begins. It is one of the most widely specified mixes on residential sites across the UK, and for good reason. It is the grade most homeowners and groundworkers reach for when

C15 concrete, also known as GEN 2, achieves a compressive strength of 15 N/mm² after 28 days. It sits in the lower strength range of commonly used concrete grades and is designed specifically for light, non-structural domestic work. It is not a premium structural mix. But for the right applications, it is one of the
