Garden Paving FAQs

The Turnbull paving team apply their wisdom to the issues of horse boxes, paving in the rain, weeds and barbecue stains

How deep should the foundations be?

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. The depth of driveway foundations depends entirely on the total weight that will be on the driveway at any one time.

What weight can the pavers/slabs take? Would my five-tonne horse box be ok?

As a rule of thumb, pavers under 50mm thickness will NOT be suitable for use in a driveway as there is not enough stone to cope with the weight of a vehicle. Call us on 01529 308839 and we will advise a suitable paver thickness for your driveway.

Can I lay garden paving in the rain?

Yes. With the Weatherpoint 365 Jointing Compound, you can not only lay paving in the rain, but you can do jointing in the rain, too. Just make sure your foundations do not become too wet or your paving surface could be affected.

Is the foundation depth dependent on the carrying weight?

Yes, 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. But call us on 01529 308839 for an accurate calculation.

How much paving do I need?

There is a handy Paving Calculator available on each product, so the hard work is done for you. All you need to know is the area you want to cover. You should also allow for wastage – so you can ensure you still have enough slabs or blocks available to complete your paving project if you drop one, or make a mistake when cutting. The Marshalls Paving Planner should help you order the right number.

How do I stop weeds growing in my driveway?

Weatherpoint 365 inhibits weed growth in the joints between pavers. Weatherpoint 365 sets like concrete and has strength comparable to 4:1 mortar when set. If you want to inhibit weed growth underneath the patio, make sure the sub-grade is completely clear of plants and vegetation before you lay the pavers and consider a Geotextile Layer.

How easy is it to lay the patio myself?

Laying a patio is fairly straightforward if you plan ahead. Take a look at our Hints & Tips page on Laying a Patio which should give you a few good pointers. Any more queries? Give us a call on 01529 308839.

What tools do I need to lay the pavers/slabs?

  • Site Preparation: Spade, Shovel, Pick, Wheel Barrow, String Line, Tape Measure, Sledge Hammer and Rake
  • Bed Preparation: Cement Mixer (or large Shovel and Wheel Barrow), Float, Compactor, Trowel
  • Laying and Preparing Paving: Lump Hammer, Spirit Level, Circular Saw, Block Splitter, Plate Compactor, Brush, Rubber Mallet, Chisel, Bolster

How far in advance do I need to place my order?

Turnbull aims to deliver pretty swiftly – within 4 to 6 working days of your order. However, some products’ availability may be different, so do call our team to check on 01529 308839.

Can I get jointing compounds coloured to match the slabs?

Yes, Weatherpoint 365 is available in three colours; Buff, Stone Grey and Black. One of these should match your paving slabs closely or provide a nice contrast.

What actually are garden paving foundations?

There are five layers in garden paving foundations:

  1. The bottom layer (often called Compacted Subgrade) is usually either sand/gravel or clay/silt. This needs to be a very thick layer and tends to be already in place (as it is the layer of soil after excavating).
  2. The second layer (upwards) is an optional layer, called the Geotextile Layer. This helps to prevent weeds and plants coming through to the paving layer.
  3. The middle layer needs to be a mixture of larger grade stones and smaller aggregate or, alternatively, limestone aggregate. Make sure this layer is at least 100mm thick after compacting.
  4. The fourth layer (upwards) should be a building sand laid on top of the compacted aggregate base.
  5. The final layer is the cement layer, on which the paving stones will lie. This guide is for garden paving. Driveways and commercial walkways require additional foundations.

Call us on 01529 308839 for advice.

Will the colour of my paving slabs fade over time?

Concrete pavers and natural stone will both fade slightly over time due to sunlight and weathering. Artificially coloured concrete pavers will fade more – and more quickly – than natural pavers.

If you are concerned about fading, we recommend buying Vitrified paving which will fade less over a long period of time. Colour differences are also apparent across different batches of product, so it makes sense to order as much as you need at the beginning of your project.

Will anything stain the pavers/slabs, for instance fat and oil?

Yes, some household and DIY products will stain your paving slabs. If you spill any fat or oil from a barbecue, for instance, it will soak into the paving stones and create areas of discolouration.

The quicker you clean a spillage the more likely it is that it will not make a permanent mark. Avoid using strong or undiluted acids directly on the pavers/slabs, as this will cause discolouration and possibly long- term damage to the pavers.

For further information on any specific stains, call our helpful team on 01529 308839.

I have bought a Project Pack of Garden Paving. Is there a set pattern for laying the paving?

No. Each Garden Paving and Driveway Paving Pack has a few suggestions of the laying patterns to use, but do give us a call on 01529 308839 and we’ll gladly help you find the best design for your project.

Here are some suggestions on patio laying patterns from Marshalls.
