Yes, we do accept new account customers subject to receiving acceptable references. Please contact us to arrange for an account form to be sent to you.

Yes, providing there is no structural requirement we can advise on the types of mixes to be used for most jobs.

This question can only be answered by the professionals associated with the project. Concrete cures at different rates depending on the constituent ingredients and the ambient conditions it is exposed to. Your laying contractor should know what sort of curing is required for the particular mix being used. Also, by following their recommendation, you can maintain whatever warranty might be associated with the work performed.

Under normal conditions, concrete has a useable life of about 2 hours. However, in summer it will lose workability more rapidly. Ideally, it should be placed and completely finished within 1 hour of discharge from the truck-mixer.

Concrete gains strength whilst hydration (the reaction between water and the chemicals in cement) takes place. This reaction forms new compounds and crystals interlocking themselves and aggregates together. This generally occurs over the first month after placing the concrete. Small strength gains could take place for years as long as moisture is still present. When the concrete does finally dry out, it stops gaining strength.

Yes, our Concrete is produced to BSI Standards

Scientists use compression and flexural mechanical strength tests to determine the strength of concrete. The strength of concrete depends to a large degree on the water-cement ratio, and the quality of the aggregates and paste in the cement.

We work from 6:00am to 5:30pm Monday to Friday, & 7:00am to 12:00pm on Saturday.

Yes, provided there is adequate access and our mixer chutes can reach. Alternatively, you can move the concrete to your laying area via a pump, dumper or wheelbarrow.

About 18-20.

We operate both 8 cu metre and 6 cu metre capacity mixers.

We can deliver the first load, you can then re-measure & tell us your remaining amount.

Measure carefully then use our concrete calculator to convert to cubic metres. Given that each 0.1 cu m is c. £10 – £15 depending on the strength, if your base is uneven allow yourself some leeway with your measurements.

Sorry, the driver needs to remain in charge of their vehicle at all times during a delivery.

We dispose of any excess concrete at no extra charge.

We work alongside trusted pump operators and can put you in touch with them. Pumps generally take about ½ hour to set up and usually require a minimum strength of a GEN3 mix to pass easily through the line.

Sorry, we do not.

If you do not wish to pay for any excess time, we will tip off any remaining concrete, ideally onto a tarpaulin.

You have 30 minutes ‘free time’, thereafter time is charged at £1.50 + vat per minute.

It is the industry terminology for how wet or dry the concrete is batched at.
