Tarmac Driveways in Welwyn Garden City, explained

Tarmac is usually the sensible answer when the area is large, the budget is real, and you want one continuous surface with nothing to maintain between the joints. What it is not is the cheap option that happens to look like the expensive one. A tarmac drive laid badly shows you inside a winter, and it shows you at the edges and in the low spots.

Which is why most of our quote is levels and drainage rather than the black stuff on top. Tarmac sheds water instead of absorbing it, so a tarmac drive is only ever as good as the fall somebody set before the first load turned up. We work that out at the survey and write it into the price, rather than finding it on the day and coming back to you for more money.

We are based in Hatfield and cover this area as part of our normal work. The survey and the written quotation are free, there is no deposit, and you pay when the drive is finished and you are happy with it.

We cover the AL7 and AL8 postcodes in Welwyn Garden City, and the rest of Hertfordshire.

What your quote covers

A free survey, with the falls and the drainage worked out before anything is priced
One fixed price in writing, no deposit, nothing payable up front
Excavation, clearance of the old surface and removal of the arisings
A compacted sub-base, and edgings or kerbs haunched in concrete to roll up against
A base course and a finer wearing course, laid hot and rolled while hot
Joints cut and sealed against thresholds and manholes, and the site cleaned down

Choosing tarmac driveways in Welwyn Garden City

Tarmac comes into its own on bigger areas. A long drive, a turning circle or a parking area priced per square metre in blocks or resin reaches an uncomfortable number quite quickly, whereas tarmac covers ground fast and keeps the cost proportionate.

You also get a surface with no joints in it. Nothing to re-sand, nothing for weeds to come up through, and nothing to rake. For a large area in Welwyn Garden City that is a meaningful difference in the time the drive asks of you over the years.

The thing to plan for is water, because tarmac is not permeable. The falls have to carry rain to a channel, gully or soakaway, and that is set during the groundwork. Colour-wise black is standard, red is available where it suits the property, and decorative chippings are an option if you want something softer.

What happens on site in Welwyn Garden City

The area is excavated and the arisings cleared, then a sub-base is built and compacted to suit the loads the drive will carry. On a larger area that loading is worth getting right, since it is a lot of surface to put back if the base is wrong.

Edgings or kerbs are installed first and haunched in concrete. Tarmac has to be rolled against something solid; an unsupported edge crumbles away within a year or two. The falls are built in at this stage so water goes where it has been planned to go.

The tarmac itself is laid in two layers on most domestic drives, a base course for strength and a finer wearing course for the finish, each laid hot and rolled while hot because that rolling is what delivers the density. Joints at thresholds, manholes and existing surfaces are cut and sealed against water tracking beneath.

What affects the price in Welwyn Garden City

We do not publish a rate per square metre, because the number would be wrong for most properties. The survey is free and the price you get afterwards is fixed and in writing. These are the things that move it:

The area, which is where tarmac earns its keep against the other surfaces
How much excavation it needs and how far the arisings have to travel
Whether the drive takes one course or the full base and wearing course build-up
The drainage the levels call for: a channel, a gully connection or a soakaway
Edgings or kerbs, and whether you want a block-paved border
Plain black, red, or a decorative chipping finish on top

Looking after tarmac driveways

Take it easy for the first few weeks and particularly in the heat. Dry steering, turning the wheel while stationary, scuffs a fresh surface, and narrow point loads like a jockey wheel or a motorbike stand will press in. Put a board under anything like that.

Keep the falls doing their job: drains clear, edges free of soil and encroaching growth. Tarmac failures almost always begin at an edge or in a spot where water has been sitting.

After a couple of years, sealing is worth considering to restore the colour and slow the drying out of the surface. Damage can be cut out and patched rather than triggering a full replacement, and a properly built drive should give 15 years or more.

Tarmac Driveways in Welwyn Garden City: Common Questions

Do you cover Welwyn Garden City?

Yes, AL7 and AL8 are inside our area and the Hatfield yard is close by. The survey and written quotation are free.

Is tarmac cheaper than blocks?

Over a larger area, generally yes, because it covers ground quickly and is not priced the same way per square metre. On a small drive the gap narrows.

Does it need much looking after?

Less than blocks or gravel, because there are no joints to sand and nothing loose to rake. Keep the drainage clear and the edges tidy, and consider sealing after a couple of years.

Is the quote free?

Yes, and the survey. No deposit, and nothing to pay until the drive is complete.

How soon can it be driven on?

Walkable once cool and able to take vehicles shortly afterwards, though it keeps hardening for several weeks, so be careful early on.

Will you need lorry access?

Tarmac is delivered hot and has to be laid while it is hot, so we need reasonable access to get it to the drive. We check that at the survey and plan around it.
