1. Overwatering the Mix
Adding extra water might make concrete easier to pour, but it drastically reduces its strength. Excess water dilutes the cement paste, leading to weak, porous concrete that cracks and crumbles over time.
Procon Tip: Always follow the correct water-to-cement ratio. If in doubt, opt for our professionally batched ready-mix concrete; precision mixed for optimal performance.
2. Incorrect Mix Ratios
The standard mix ratio: 1 part cement, 2 parts sand, 3 parts aggregate, is often altered in an attempt to cut costs. But reducing cement or increasing stone content compromises the structural integrity of the concrete.
Procon Tip: Stick to proven mix designs. Our ready-mix solutions are engineered to meet British Standards and tailored to your project’s needs.
3. Pouring in Extreme Weather
Temperature extremes can wreak havoc on concrete. Hot weather accelerates curing, leading to surface cracks. Cold weather can freeze the mix before it sets, causing internal damage.
Procon Tip: Schedule pours during mild conditions (ideally between 10°C and 27°C). We also offer admixtures and curing advice for challenging weather.
4. Poor Site Preparation
A poorly prepared base leads to uneven settling, cracking, and long-term failure. Common oversights include failing to remove soft soil, skipping compaction, or neglecting a gravel sub-base.
Procon Tip: Always start with a solid, level foundation. Our team can advise on ground preparation to ensure your slab performs as intended.
5. Inadequate Mixing Time
Under-mixing results in inconsistent texture and strength. Over-mixing, on the other hand, can break down the cement matrix and reduce durability.
Procon Tip: Let us handle the mixing. Our automated batching systems ensure every load is consistent, reliable, and ready to pour.
