Frequently Asked Questions & Concrete Advice
Get immediate, expert answers regarding concrete ordering, on-site volumetric batching, slump classes, line pump hire, and site preparation across Edgware.
Planning a concrete pour requires careful coordination. Here are comprehensive answers to the most frequent technical, delivery, and logistical questions we receive from homeowners and contractors across North West London.
How does volumetric concrete mixing work on site?
Unlike traditional drum mixers that transport wet concrete batched miles away, volumetric mobile mixers store separate dry aggregates, cement, and water. Mixing occurs inside an internal auger only when the truck begins discharging. This ensures you get maximum workable time, allows on-site slump adjustments, and stops the instant your shuttering is full—eliminating excess waste charges.
What is the minimum order quantity for concrete delivery?
Our minimum delivery order is just 1.0m³ (cubic metre). Whether you need 1.5m³ for a garden shed slab or 40m³ for commercial piling, our volumetric fleet accommodates any size project without part-load penalty fees.
How much notice do I need to give when booking?
We recommend giving 24 to 48 hours' notice to lock in your preferred morning or afternoon 2-hour window. However, we also operate same-day emergency dispatch slots for urgent requirements across Edgware, Stanmore, and Mill Hill.
How much offloading time is provided?
We allocate 10 minutes of free discharge time per cubic metre ordered. For example, a 4m³ pour includes 40 minutes of offload time, which is plenty for wheelbarrowing or chute pours.
Can concrete be poured in the rain?
Light rain or damp conditions are safe, but heavy rain can wash out cement and weaken the finished slab surface. We recommend having plastic polythene sheeting ready to cover fresh concrete immediately following placement.
When is concrete pump hire recommended?
If your pour site is located in a rear garden, through a terraced building hallway, over fences, down in basements, or further than 5 metres from vehicle access, ground line pumping provides rapid, mess-free concrete placement with zero wheelbarrow fatigue.
How long does concrete take to cure?
Concrete sets firm within 2 to 4 hours and can be gently walked on after 24–48 hours. Light vehicles may drive on driveways after 7 days, and full structural design strength is achieved after standard 28-day hydration.
