Tarmac Driveways in Welwyn Garden City

Tarmac gives a clean, understated finish that can work well on a Welwyn Garden City property, provided the position with the Estate Management Scheme has been checked first. A large part of the town requires consent before paving or hardstanding is laid across an open frontage, along with a reasonable balance between hard and soft landscaping, so it is worth confirming your own situation with Welwyn Hatfield Borough Council before ordering any work. Where tarmac is appropriate, it gives a smooth, low key surface that does not compete visually with the greenery the town is known for. We install tarmac driveways across Welwyn Garden City, and can also advise on keeping the surfaced area to a sensible proportion of the plot where that matters to the scheme. We quote free of charge and there is no obligation to proceed. Contact us and we will come out to talk through what will work on your frontage.

Where tarmac is the right fit for a Welwyn Garden City property, here is what it offers.

A clean, understated dark finish that does not compete visually with mature hedging and grass verges
Cost effective compared with paved or resin surfacing, particularly on larger frontages
Laid as a single continuous surface, with no joints for weeds or moss to take hold in
Quick to install, with most driveways ready for use within a couple of days
Durable enough to handle daily vehicle use without significant wear over time
Flexible under load, so it resists cracking better than a rigid poured surface
Low maintenance, generally just a sweep or an occasional wash to keep it presentable
Can be kept to a defined, sensible area with kerb edging, supporting a proper balance of hard and soft landscaping
A practical option for properties where budget is a bigger factor than intricate design detail

It is a straightforward, tidy option once your position with the Estate Management Scheme is confirmed. Take a look at our gallery for examples of driveways we have completed locally.

Tarmac is usually the most economical way to cover a driveway, and the bigger the area the more that advantage shows. Every drive in Welwyn Garden City is still priced after a free site survey, because what is already under your feet decides most of the cost.

What moves the price up or down

If the existing base is sound we can often overlay it, which is quick and keeps the cost down. If it has to come out and be rebuilt, that adds excavation, muck away and materials. After that it is the size of the area, the drainage you need, any kerbing or block edging around the perimeter, and how easily a wagon can reach the site.

We put the figure in writing after the survey. The survey and the quote are both free, whether you go ahead or not.

Tarmac is not the right answer for every drive, and we would rather tell you that at survey than after the job. Here is where it works and where it does not.

Where tarmac makes sense

Large frontages where cost per square metre matters more than detail. Drives that need to be usable quickly, since tarmac is ready to drive on within a day or two of laying rather than needing a curing period. Awkward shapes, because it is laid as one continuous surface and follows whatever outline the drive has without cutting. Anywhere you want a plain, tidy finish with almost no upkeep.

Where something else may suit better

If you want colour, pattern or a period look, block paving gives you far more to work with. If you need the surface to be permeable so rainwater drains through it, tarmac does not do that on its own and you would be looking at resin bound or permeable blocks instead. And if there is any chance of needing access to a drain or cable underneath, block paving lifts and relays where tarmac has to be cut out and patched.

Ask us which suits your drive

If you are still weighing up surfaces, this is how tarmac stacks up against the other three we get asked about most.

	Tarmac	Block paving	Resin bound	Gravel
Finish	Plain black, smooth and uniform	Traditional, laid in patterns, wide colour choice	Smooth and seamless, natural gravel look	Natural and informal
Relative cost	Lowest of the four on a large area	Higher, rises with pattern and cutting	Higher	Lowest on a small area
Time on site	One to two days on a straightforward drive	Three to five days	Two to five days	One day
Permeable (SuDS)	No	Only with permeable blocks and jointing	Yes	Yes
Weeds and moss	No joints to grow in	Can appear in the joints	No joints to grow in	Common without a membrane
Repairs and access below	Cut out and patch, the patch usually shows	Blocks lift and go back down	Needs cutting out	Simple

Tarmac looks like the simplest surface to lay, which is exactly why it gets laid badly. Most failures come from a thin or poorly compacted base, or from laying onto a surface that was not fit to be overlaid. This is the order we work in on every job in Welwyn Garden City.

Survey and set out. We check whether the existing surface can be overlaid or has to come out, look at the levels and work out where the water goes. You get a written quote after this, free either way.
Excavation or preparation. Either the old surface is dug out to the depth the ground calls for, or a sound existing base is cleaned and prepared for an overlay.
Sub-base. MOT Type 1 laid in layers and compacted. This carries the weight, not the tarmac on top.
Edgings. Kerbs or block edging bedded and haunched in concrete where the drive needs a defined boundary. Tarmac laid to a loose edge breaks away over time.
Base course. The first layer of macadam laid and rolled, giving the strength and taking up the levels.
Wearing course. The finer top layer laid hot and rolled to a smooth, even finish with the falls built in so water runs off rather than sitting.
Compaction. Rolled while still hot. This is what gives the surface its density and its life. A drive that is not properly rolled will ravel at the edges within a couple of winters.

A straightforward drive is usually one to two days, and longer if the base has to be dug out and rebuilt. You can walk on it the same day and drive on it the next.

  Amwell Driveways did an outstanding job on both my new driveway and the back fence. The team were organised, skilled, and clearly take real pride in their work. The driveway looks superb and the fence is solid, straight, and beautifully finished. Everything was completed on time and the whole experience was smooth from start to finish. I’m genuinely impressed and would recommend them to anyone looking for quality workmanship.

  We are really pleased with our new resin and porcelain patio in our garden.  It was finished to a really high standard.  The team, who were very punctual and professional, worked hard and cleaned up really well after themselves when the work was done.  The whole operation was very smooth from Paul initially coming round to discuss the options and provide a quote, to Martin managing the team over the five days that they were there building our new patio. After my experience, I would highly recommend Amwell Driveways.

  We approached Amwell to do a design and deliver landscape project for our house.  The work involved stripping the existing area of overgrown trees, lawns and block paving drive from the front and back of our house.  These were replaced with a resin-bound drive , new patio, lawns and beds ready for planting. The design work was carried out by Paul Williams from Amwell.  He is a highly experienced and knowledgeable professional who was able to offer us advice and insights to achieve a better result and avoid costly mistakes.  He was not at all pushy and there was no hard sell.  Perfect. The work was done in less than 2 weeks and to a very high standard.  We are delighted with the end result and have no hesitation recommending Amwell.

How much does a tarmac driveway cost in Welwyn Garden City?

Tarmac is usually the most economical of the surfaces we lay, and the larger the area the clearer that advantage gets. The figure depends on whether we can overlay your existing base or need to dig it out, the size of the area, the drainage and any edging. We measure up and put it in writing after a free survey, with nothing to pay either way.

How long does a tarmac driveway take?

A straightforward drive is one to two days. If the base has to come out and be rebuilt, allow three or four. You can walk on it the same day and drive on it the next.

Can you lay tarmac over my existing driveway?

Sometimes, and it is the cheapest option when it works. The existing surface has to be structurally sound, not cracked through, and the extra height must not cause a problem at the door threshold or the kerb. We will tell you at survey whether an overlay is sensible or whether you would just be covering up a failing base.

Is tarmac permeable, and will I need planning permission?

Standard tarmac is not permeable. If you are laying more than five square metres of new hard surface between your house and the road, the water needs to drain to a soakaway, a border or a lawn rather than onto the road, otherwise you would need planning permission. We build that drainage in as part of the design and tell you where you stand before any work starts.

Why does tarmac go grey and patchy over time?

The bitumen binder oxidises in sunlight, which lifts the colour from black towards grey. That is normal ageing and not a fault. Loose stone at the edges, called ravelling, is different and usually means the surface was not compacted properly while hot, or was laid to an unsupported edge.

Can tarmac be repaired?

Yes, but a patch almost always shows, because new tarmac sits darker than weathered tarmac and never quite blends. If you expect to need access to a drain or cable underneath, block paving is the better choice since the blocks lift out and go back down invisibly.

Does tarmac need sealing?

No. Sealing is sometimes sold as a way to restore the colour, and it does that for a while, but it is cosmetic rather than structural and needs redoing. A well laid drive does not need it, and we will not push it on you.

Will oil or petrol damage it?

Spilled fuel and oil soften the bitumen binder, so a persistent drip in the same spot will eventually leave a soft patch. It is worth putting a tray under a leaking car rather than leaving it. Ordinary use does no harm.

Can you edge it in block paving or kerbing?

Yes, and on most drives we would recommend it. A defined edge stops the tarmac breaking away at the perimeter, and a contrasting block border lifts the look of what is otherwise a plain surface.

What guarantee do you give?

Every tarmac installation comes with a 5 year workmanship guarantee from Amwell Driveways Ltd, and you get the paperwork on handover. Our Price Promise is matched against any written quote on the same materials and the same guarantee.

Do you actually work in Welwyn Garden City?

Yes. Welwyn Garden City is part of the area we cover from our base in Ware, and we lay tarmac driveways there regularly. The people who come out to quote your drive are the people who lay it.
