Health and safety
Q. What are the health and safety risks of handling concrete?
There is always a risk to manage to ensure the safety of the people involved, no matter the size or location of the job. We strongly recommend you take the time to read our Concrete Health and Safety Datasheet and the information on our health and safety page.
Q. How much concrete will I need?
- Concrete quantities, like any other measure of volume are calculated by multiplying length x width x depth (or height) and are measured in cubic metres (m3).
For example: If a room measures 3m x 4m and the depth of the concrete floor is to be 100mm, the calculation is 3 x 4 x 0.1 = 1.2m3.
- Make sure that you work out your sum in the same units (don't mix metres and millimetres or yards and feet). Bear in mind that it's generally easier to work with the metric system.
- The conversion table below may help, or use our volume calculator.
To convert cubic yards to cubic metres - multiply by 0.765
To convert cubic feet to cubic metres - multiply by 0.028
Q. What preparation is required?
- For concrete bases, floors and drives, the area should be dug out to twice the required depth of concrete (a minimum of 100mm or 4 inches is advisable, so you should dig the area out to 200mm or 8 inches depth), and the soil should be compacted.
- A layer of hardcore 100mm deep should then be placed and compacted to give the concrete a solid base and prevent sinking.
- A thin layer of sand on top of the hardcore will provide a smooth surface to work from and make calculation of the quantity required easier as it will help to prevent variations in the depth.
- If you use a layer of polythene damp proof membrane between the hardcore and concrete, it will help to stop water being absorbed from the fresh concrete by the hardcore and problems with rising damp on your finished project.
- Remember, to take into consideration insulation depths when laying concrete for an internal floor.
- Ground conditions must be stable enough to take a heavy lorry. Paving slabs, domestic block paving, etc. will not accept the weight of a truck-mixer.
- Brickwork, windows, tarmac, etc. should be protected against splashing
Q. When do I place my order?
- A minimum of 48 hours notice is required for concrete orders via online ordering, 24 hours is required when ordering on the phone, but if you can give us more than that, there is a greater likelihood that we can agree the time of delivery with you.
- All orders will be confirmed with you before dispatch.
Q. How do I pay?
- Payment can be made by Visa, MasterCard or Switch at the time of ordering, or for trade customers through a credit account subject to status.
- Credit and/ or bank references may be required.
- Please have your details ready as card processing will take place online or over the phone.
Q. What happens if I order too much concrete?
Delivery of product
Q. I’m using wheel barrows to move the concrete during delivery - how long will it take?
- Here is an example of how many wheel barrows it takes to move 1m3: Approx. 20 wheelbarrow loads per m3!
- Make sure you have the capacity and man power to move concrete this way.
- Take into consideration the setting time of concrete when trying to move concrete via wheelbarrow.
Q. How much does a cubic metre of concrete weigh?
- One cubic metre of concrete weighs around 2.4 tonnes. That equates to about 20 wheelbarrow loads per m3!
Q. What should I do when the concrete arrives?
- Check the delivery ticket to confirm the correct concrete and quantity has been delivered.
- Advise the driver where the concrete is to be unloaded
- Direct the truck-mixer driver to the point of placing
Q. How do I know if the truck mixer will be able to get to where I need it?
- The dimensions of a 3m3 3.5m3or a 4m3 truck mixer are:
Overall width - excluding mirrors: 2491mm
Overall width - including mirrors: 2923mm
Overall length: 7168mm
1st chute pivot to end of 2nd chute: 1906mm
1st chute pivot to end of 3rd chute: 2669mm
- Please ensure that you can provide safe and reasonable access for the truck mixer, as we cannot be held responsible for damage caused to footpaths, existing driveways etc.
- You may be asked to sign an indemnity form at the time of delivery.
- Assuming that the truck can position itself at right angles to the job, the chutes have a maximum reach of approximately 2.5m or 8ft. This distance is reduced to around 1.5m or 5ft if the truck is only able to draw alongside the job.
- Please allow a minimum of 8ft 6 inch (3m) for the vehicle to enter an opening, such as a gateway. This distance will need to increase if the vehicle cannot drive straight at the opening.
Q. When the truck mixer arrives on site what should I expect?
- When the truck mixer arrives on your site, the driver will assess the required delivery location, and discuss with you the best and safest method of discharging the concrete into the place you require.
- If it is not possible to get the truck mixer close enough, and you have notified us at the time of ordering that you may require it, off-loading directly into wheelbarrows will be possible.
- If the truck mixer is required on site for more than 30 minutes, a small additional charge may be applied.
- It is a legal requirement that the driver washes his chutes before he enters back onto the highway after discharge. This will require a wheel barrow, waste ground or skip to minimise your mess on site. All vehicles will have its own wash of hose and water on board. Please be aware even though we are offering a Minimix service it is still a heavy goods vehicle.
Q. How long can the truck be on site?
- The truck is normally on site for 30 mins. Any additional time will need to be prearranged with the sales team.
Q. Will you deliver 24 hours a day?
- The majority of our sites can open for out of hours deliveries.
- Additional plant opening costs will apply with extra notice required before delivery.
- Common reasons for late night deliveries are highway maintenance, inner city projects or health and safety reasons.
Q. Will the delivery time be precise?
- We always aim for the delivery time given but the very nature of small volume ready mixed concrete deliveries makes the time a little unpredictable.
- We do aim to deliver within an hour of the specified time but you will be notified if we are delayed any longer than this.
Q. Will you undertake a site visit?
Laying your product
Q. How long do I get before the concrete goes off?
- The chemical reaction that takes place within a concrete mix begins as soon as the cement and water are mixed together.
- This means that usually you will have between 1 - 2 hours once the concrete arrives on your job to place, level, compact and finish the mix.
- Higher strength mixes will generally give a little less working time than lower grades.
- Please ensure you have enough people to complete your project on time.
- We do offer high performance products which gain early high strengths, when faster strength gains are required.
Q. What should I consider if I’m using a concrete pump?
- A concrete pump would be used when barrowing is just not an option. For example, the concrete volume ordered is too much for you to move via wheel barrow, or too far for you to barrow.
- A concrete pump is attached to a truck. It is known as a trailer-mounted boom concrete pump because it uses a remote-controlled articulating robotic arm (called a boom) to place concrete with pinpoint accuracy. Boom pumps are used on most of the larger construction projects as they are capable of pumping at very high volumes and because of the labour saving nature of the placing boom.
- Smaller truck mounted pumps are available for domestic projects and smaller concrete volumes.
- A concrete pump is a separate vehicle required and tends to arrive on site 45 minutes before your ready mixed concrete order. This gives the operator time to set up.
- Guidance on concrete pumping companies can be obtained from our sales team.
Q. What tools will I need to lay concrete?
- Most people will already have the tools required to handle and place concrete, but check the list below to make sure you are fully prepared:
Wheelbarrow - Essential if you need to transport the concrete around your job
Shovel & Rake - For moving the concrete
Spirit level - To ensure accuracy
Tape measure - For calculation of quantity required
Timber - To make pegs, formwork, and tamping beam
String & pegs - For setting out the area to be concreted
Trowel or float - For surface finishing
Brush - For cleaning up afterwards
Please be aware that concrete is both abrasive and alkaline, so protective clothing, gloves, boots, overalls and safety glasses etc should always be worn. Cement can burn sensitive skin.
