Hot Tar and chipping Surface Dressing Cornwall

Have you ever wondered what a tar-and-chip surface is made of? Or how it’s made? … Have you ever considered having a tar-and-chip driveway at your home or business in Cornwall? A tar-and-chip driveway is hard-wearing, low maintenance, and less expensive than many other forms of surfac

Hot Tar and chipping Surface Dressing CornwallWhat is a Tar and Chipping Surface Dressing?

A tar-and-chip surface is made by covering hot bitumen – aka asphalt – with stone aggregate.

This surfacing method is a good-looking, versatile surface that has been a mainstay for driveways and carriageways in the UK for centuries. It’s also known as tar and chippings, tar and stone, tar and granite, chip and seal, seal chip, and tar bond. ing.

How is a Tar and Chip Surface Made?

A driveway must have strong foundations. We pack a mixed-aggregate sub-base into our excavated site, and then cover it with hot bitumen, which acts as a seal over the sub-base. Stone aggregate is spread over the sticky, molten asphalt, and a heavy roller presses the pieces of stone firmly into their bitumen bed.

Often, we find we’re laying a new tar-and-chip surface on top of an existing driveway. In this case, we’ll clear the site of debris and fill in any potholes. Thorough preparation is always important.

Do You Need Drainage with Tar and Chip?

To be compliant with current UK Building Regulations, you must show evidence of adequate drainage. Because a tar-and-chip surface is impermeable (water can’t pass through the bitumen layer), provision must be made for the duct of surface water. But this doesn’t mean channelling the water to a public drain!

After some serious flooding in 2007, legislation was introduced to enforce the provision of alternative drainage for all new (and impermeable) driveways and patios. If water can run off your driveway into a stream or a garden, that’s fine. If not, we’ll incorporate a simple drainage system to take it there.

Is Tar and Chip Expensive?

A tar-and-chip driveway is inexpensive to install and costs next-to-nothing to maintain. Tar-and-chip doesn’t always last as long as some other surfaces. But even so, over a lifespan of approximately ten years, it’s an economical choice.

What Aggregate Can I Have in My Tar and Chip Driveway?

At Driveways Cornwall, we specialise in two very beautiful kinds of aggregate: grey granite – angular pieces of crushed granite with flat, reflective surfaces; and pea shingle – small, naturally smooth stones in shades of light-brown.

A tar-and-chip surface provides excellent traction, whatever kind of aggregate you choose. Because the stones are held firmly in place, tyres and shoes don’t go skidding about like they do on loose gravel. And because the stones protrude from the bitumen base, tyres and shoes are able to get good purchase in wet or icy conditions.
