Driveways in Merritown
Drives, hardstanding and patios on low, wet ground, where the drainage decides the job before the surface does.

Out at Merritown the ground is the job. It sits low, it stays wet for a good part of the year, and a soakaway here is as likely to fill as to empty. So a drive has to be built to move water somewhere real, and that gets decided before anybody talks about what the surface will look like.
The trouble in Merritown tends to be water. There is a pool across the entrance every time it rains, the ruts hold it for days, and the gully by the gate stopped taking anything a while ago. Or the hardstanding you park the van on has gone soft and the wheels are sinking into it. Or the patio behind the house stays damp, goes green and is genuinely slippery by October.
None of that gets fixed from a photograph. We come out, survey where the water comes from and where it can go, open a hole to see what stone is under the surface and how far down the ground is soft, and then price it: excavation, muck away, sub-base, edgings, surface and drainage, each on its own line. If the honest answer is that the drainage has to be sorted before a new surface is worth laying, that is what the quote will say.
The work
Building a drive that stands up on wet ground
The dig, and why the depth is different here. This is wet ground, so the formation is everything. We excavate down to something that will carry a load, lay a geotextile membrane so the stone and the subsoil cannot mix, then bring a compacted sub-base up at a depth set by the ground rather than by habit.
Without that separation the sub-base pumps down into wet subsoil under traffic, which is exactly how a drive turns into ruts a year after it was laid.
Falls first, so nothing runs at the house. Then a channel drain across the entrance to stop the lane emptying onto your drive, a gully or linear drain at the low point, and a real outfall for it. This land sits in flood zone 2 with a high surface water rating and the Moors about a kilometre away, so where the water is allowed to go is the design rather than an afterthought. Where the ground will not take it we say so instead of digging a hole and hoping.
On ground like this a permeable drive is often the sensible answer, because the drive becomes the storage: permeable blocks over open-graded stone hold a downpour in the voids and let it away slowly. It only works built as a system, with clean stone, the right jointing grit and somewhere for the water to go once it is through, with a haunched kerb or edging round it so the field cannot creep. Tarmac for length and weight, resin bound where a sound concrete or tarmac base already exists, block paving where cars turn, a concrete pad where a van or trailer stands in one spot all winter. Patios go on a full mortar bed with the finished level kept clear of the damp proof course, so the water runs off instead of ponding and staining; patios in Merritown covers that side. There is smaller work as well: silt out of a gully, potholes cut out square, a sunken bay lifted and relaid, a re-sand where the kiln dried sand has washed out and weed has taken the joints.
How it runs
Laying a drive on wet ground: how we run it
Thomas comes out, walks the ground with you, checks where the water runs now and prices the drive himself. One visit settles the dig, the base and the surface. The quote lists excavation, muck away, sub-base, edgings, the surface and drainage, each on its own line.
Access decides the plan. If a grab lorry can reach the front, spoil goes straight out and stone comes straight in. If it cannot, it is dumper or barrow work, which takes longer. The ground in Merritown is often wet, so we dig in dry spells where we can and keep the lane clear of mud. The spoil leaves with us, and the site is left tidy each evening. If the dig turns up an old land drain, a soft pocket or buried rubble, you see a photograph and agree a price before we deal with it.
More than five square metres of new hard surface at the front needs planning permission unless it is permeable or drains to a border, lawn or soakaway on your own land, and Planning Portal guidance on paving your front garden explains the test. A patio behind the house at ground level is permitted development. Bournemouth, Christchurch and Poole Council is the authority, and no conservation area covers Merritown, though the council keeps the list if you are near a listed building.
Cost
Wet ground is what a driveway price turns on here
The surface you choose is the smaller part of the cost. What goes under it, and how wet the ground is, decides most of it.
Depth of dig. On firm, dry ground a normal sub-base depth does the job. On ground that stays wet, the dig goes deeper, more crushed stone goes in, and a geotextile layer may be needed to stop the base pumping up into the stone. Heavier, wetter spoil also costs more to cart away.
Drainage. Merritown has a high surface water rating, and parts of it sit in flood zone 2 on the Environment Agency flood map. A permeable surface, a channel drain across the entrance or a soakaway may be needed, and that is a line of its own.
Getting in. A lorry to the door is quick. A long gravel access, a narrow gate or a verge that will not take a heavy vehicle means smaller loads and more trips.
Edgings and finish. Kerbs, block edgings and any steps are priced separately from the main surface, and block paving prices differently from gravel or tarmac laid on the same base.
Ask any other firm: what depth of sub-base is going in? Where is the surface water going? Who takes the spoil away?
If it is urgent
A lifted block, or a drive holding water
Ring rather than filling in the form. A lifted block by the front door, a sunken patch that trips people, or a gully that has stopped taking water needs dealing with. If water is now running across the drive towards the house or out onto the lane, say so when you call.
On the first visit we make it safe, lifting and relaying the worst blocks or clearing the gully, and the full repair is priced after. Scheduled work is Monday to Friday, 8am to 6pm. If we cannot answer, you will get a call back.
Worth knowing
Where your rainwater is supposed to go when the ground is already full
Surface water is the whole story here. The ground is naturally wet, so infiltration is not a safe assumption: a soakaway needs a percolation test rather than a guess, and around Merritown plenty of test holes fill and stay full. Approved Document H sets out the order you are meant to work through, soaking away first, then a watercourse, then a sewer as the last resort.
If a test fails we look at a positive outfall or at permeable construction sized to hold water and release it slowly, and we will tell you which before you commit to a surface, not after the diggers have gone.
Start by checking your own address on the government flood risk service before you change anything: surface water risk here is not the same field to field, and it tells you whether you are designing for a heavy shower or for a genuine event.
Then watch your levels. Raising a drive or a patio so that it sheds towards the house, or across a route water has always taken, moves the problem rather than solving it, and it can put it on a neighbour. Falls away from buildings, a channel drain where the water has to cross, and nothing built that dams the flow.

Questions
Questions about driveways in Merritown
The ground by us stays wet. Will permeable paving still drain?
Only if the water has somewhere to go once it is through. Merritown sits on naturally wet sandy ground that is close to flat, so a permeable build can fill and stay full instead of emptying. We dig a pit and watch it before specifying anything, and where infiltration fails the surface water goes to a positive outfall. A permeable drive over saturated subsoil just puts the puddle underground where you cannot see it.
We are in flood zone 2. Does that change the design?
It changes where the water is sent, not what you are allowed to lay. Merritown falls in flood zone 2 with a high surface water band, and the Moors watercourse is under a kilometre away. So the new surface must not raise levels against the house or push run off onto a neighbour. We set the finished level so water leaves towards a drain or a soakaway well clear of the building, and the quote states where it discharges.
Why does the dig go deeper on this kind of ground?
Because there is more soft material to get through before anything will carry a car. On the wet sandy ground out towards Hurn the upper layer holds water and has no bearing at all, so it comes out. The base then goes back in compacted layers with a geotextile between the subgrade and the stone, otherwise the two mix and the stone quietly disappears into the ground over one winter.
Is a dry spell in summer better for working here?
It is, and on naturally wet ground we would rather dig in one. The paving is not the problem, running a machine over saturated subgrade and churning it is. Where the job has to happen in a wet stretch we board the route, open smaller sections and get stone in on the same day so nothing sits open. Whichever it is going to be, we say so at the visit, not after the start date.
What is actually itemised on the quote for this?
The dig and the depth we are taking it to, the stone base and its thickness, any geotextile, the edgings, the surface, the drainage run with the point it discharges at, and taking the arisings off site. On wet ground like Merritown the drainage line is the one worth reading twice, because that is where both the money and the risk sit.
