Paving FAQs

What are project packs?

Project packs contain all the different sized slabs you need to lay a patio. For example, our Marshalls Indian Sandstone comes in a 15.2 m2 project pack. It contains 62 separate slabs in 5 different sizes. This means you can create a patio design knowing you’ll have no waste at all. We can supply you with helpful laying patterns if you wish!

What is a bulk bag?

Bulk bags are big dumpy bags used for delivering larger amounts of aggregates, cobbles etc. They weigh between 850-975kg. Reputable builders’ merchants will make the weight of bulk bags very clear. The weights for the contents of bags is set by the Builders Merchants Federation and Trading Standards. Bulk bags are delivered kerbside by lorry and the contents can be easily barrowed in smaller quantities wherever you need to use them. Our product pages will tell you how much ground you’ll be able to cover if you spread material at a depth of 25mm, the minimum recommended depth for chippings and aggregates.

Is the brand of the paving important?

Turnbull only sells Marshalls and Stonemarket paving and there are very good reasons for our choice. We supply high quality paving with excellent technical consistency and great durability. We know our sandstone paving is quarried from stone with high density which means it doesn’t retain moisture or green up with algae. Much of our imported stone has been ethically sourced and audited by the Ethical Trading Initiative. Look for the Fairstone label. Our reconstituted stone paving has been manufactured with a high cement content to ensure its strength. You’ll find cheaper brands, but they are less resistant to moisture and will crack more easily.

What is the Marshalls Stone Standard?

All stone supplied by Marshalls exceeds the base technical levels set by British Standards for stone and manufactured concrete paving products. Marshalls have their own exacting technical standards for paving strength and porosity, called the Marshalls Stone Standard. And what’s more, all their stones and slabs are repeatedly tested by an independent UKAS accredited laboratory. So, when you see ‘Stone Standard Exceeded’ on a Marshalls product, you know you’re getting paving, walling or driveway blocks that are technically superior and of the highest quality!

How do I make sure I’m getting the best concrete paving prices?

It’s good to shop around for different paving slab prices, but as with many consumer choices, you get what you pay for when it comes to paving. Cheap concrete paving will have a lower cement content. These slabs are more likely to crack or fail under pressure. Prices for high quality concrete blocks and paving slabs reflect the fact that they contain real stone aggregates and a high cement percentage. Marshalls and Stonemarket have production processes designed to ensure their paving is consistent, reliable and good value for money.

Will the colour of my paving vary from the image online?

All our paving and walling images are supplied by the manufacturers and, of course, they go to great efforts to make sure photos represent the product as closely as possible. We do recommend you see a sample before buying, and, if you are installing a large area of paving, that you make sure all packs come from the same batch as there be some colour variation between batches.

Can I return paving if I don’t like the colour?

You can return delivered product(s) you have purchased within 14 days after the day of delivery for any reason (including if you simply change your mind or don’t like the colour). To do so you must let us know in writing via email to customer.service@turnbullsonline.co.uk, or contact us by phone on 01529 308839. There is a charge for returns, but this varies according to the product, so best to get in touch as soon as you have made that decision. Please be aware that the pack must be complete and unopened in order for it to be returned. Click here for our full Turnbull Returns Policy

How do I calculate how much I need?

We can help you work out how much paving you’ll need if you have some basic area measurements to hand. Call our lovely paving team on 01529 308839. Alternatively, you might like to try out the Marshalls handy, free online Garden Paving Planner here.

What kind of jointing compound do I need?

Our paving manufacturers produce jointing compounds that are technically superior to the traditional ‘1 part cement to 4 parts sand’ variety. Stonemarket Fast Point Jointing Compound and Marshalls Weatherpoint 365 both speed up installation, can be used in wet and dry weather conditions, come ready mixed and will not stain the surface of the slab. Some of our products come with FREE jointing compound so it’s worth have a chat with us to find out the best option for your paving.

How do I find a good paving installer?

We recommend qualified Marshalls and Stonemarket registered installers. They belong to a national network of independent professional installers who know the products and whose work has met high levels of competence and performance.


How deep do my foundations need to be?

If you are laying a driveway you will need considerably deeper foundations than if you are laying a patio. So, for instance, garden patio foundations are around 150mm deep. A driveway for around four tonnes of vehicle will need around 300mm of foundations. Foundations for garden pavers need to be at least 150mm deep. If you are putting a patio or pavers next to your house, the surface of your patio must also be 150mm below the damp proof course of the house, (2 Bricks below the damp proof course). The depth of driveway foundations depends entirely on the total weight that will be on the driveway at any one time. Not sure? Consult a Local Builder for full advice and guidance.

Where can I buy sub-base?

Turnbull branches stock sharp sand and MOT 1 (Dept of Transport grade) sub base materials for patios and paths. If you are local to one of our branches our paving team will be able to advise you on quantities and arrange delivery. Otherwise, you’ll find all good builders’ merchants have a ready supply for delivery to your door.

Can I use bleach or similar strong cleaning products to wash down my paving?

We really advise against it. Brushing with hot soapy water is all that is required. Go for a domestic pressure washer if you want a gadget to do the job but sweep up first, keep the power on medium and keep the nozzle at an angle and about 20cm away from the slab surface. If you have pets and frequently clean up after them, we’d recommend installing one of our vitrified stone paving options as they are less porous than natural stone.

What do I do with leftover paving slabs?

We do get asked this surprisingly often so here are our top tips: donate them to a local allotment society or school gardening project; sell them online; recycle them by contacting a local waste management contractor or put them behind your shed until you can think of another use for them.

What can I do with empty dumpy bags?

Lots of things! They are great for collecting leaves and garden waste for composting – not pretty to be sure, but the perfect size! You can use them to cover garden furniture in the winter, or cut them up for ideal weed suppressant material. Some people we know even cut some drainage holes in the bottom and use them as raised beds, growing spuds very successfully!

Forest Garden timber products FAQs

How easy are flat-packed items to assemble?

Most Forest Garden products are easily assembled by one or two people. They come with all the fixtures and fittings you’ll need, and have detailed assembly instructions. What’s more, you can click in to Forest TV which has a great range of ‘How to’ videos to help you. In some cases, an item will come to you fully assembled rather than flat packed.

Can you help with assembling my new shed/summerhouse?

Yes we can, but this is an additional cost and we only offer an assembly service by prior agreement at the time of purchase. Definitely one to have a chat to us about! Give us a quick call on 01529 308839 to see if we can help.

What does it mean if my planter or garden bench is made from pressure-treated wood?

Pressure treated products are made from wood that has been naturally or kiln dried to remove moisture. It is then placed in a pressure treatment tank to allow preservative to penetrate the wood. The wood comes out with a green tinge when new, but fades to a honey or beech colour over time. Wooden garden products that are pressure-treated withstand weathering very well. Forest Garden guarantees theirs for 15 years and they do not need annual wood preservative treatment. You will see some garden timber products on sale that are dip-treated. It’s generally cheaper in price because dipping is a quicker treatment process. Dip treatments thin and fade over time.

Can I stop my Forest Garden product turning grey?

Of course! If you want to keep the brighter colour of fresh timber we recommend you give your wooden product a fresh coat of good quality wood preservative after you’ve had it for about a year. This will have the same brightening effect as a good wax and wash does on your car. But avoid doing this on a baking hot day – the timber will dry out too quickly and it may cause warping.

Are Forest Garden products suitable for painting?

Absolutely and we say go for it! Painting your garden furniture is a great way to personalise the look of your garden. There’s a huge range of garden paint colours available to buy. Choose a mild, dry day and if you don’t like it, it’s easy to change.
