Patios in Wareham

The town sits between two rivers on ground that floods, so the instinct to raise a patio out of the wet is the one thing that causes the most trouble here.

In Wareham the right patio is a low one. Building the surface up to keep it clear of standing water pushes the level towards the damp course and sends the run off next door, so the answer is to keep it down and drain it deliberately.

Wareham gardens bring terraces that hold water in a dish after heavy rain, paving raised over the years until it is nearly level with the back door, and walled plots where the old flags have gone rocking and green.

In Wareham each of them is answered by levels rather than by slabs. We lift a flag, look at the bed beneath it, run a level off the damp proof course and find out where surface water goes today. Then the whole job goes into one written itemised quote with the excavation, the muck away, the sub base, the edgings, the paving and the jointing listed on their own lines. Both the visit and the quote are free.

The work

Low terraces, walled gardens and where water goes

Taking layers off. A lot of the work in Wareham starts by removing what previous owners added. Old paving, concrete and made ground get excavated back to a firm formation and to a sensible height, and the spoil goes out by skip or grab lorry, priced by the load. On the town streets that is barrow work through a passage, which belongs on the quote as its own line.

Base and bedding. Compacted hardcore, MOT type 1, in layers, then a full wet mortar bed with a slurry primer on the back of each slab. Not five dabs, and not a screeded sand bed. On ground that gets wet, a void under a slab is a reservoir and the frost does the rest.

Falls and the damp proof course. The surface falls away from the house and stops at least two courses below the DPC. Where a threshold sits low, a channel along the wall takes the water at the door rather than the paving being lifted to meet it. In a town where the ground is already low, that discipline matters more than anywhere.

Drainage that has somewhere to go. A channel drain at the low end into a gully, a soakaway only where a hole has proved the ground will take one, and a permeable border where the soil drains. Water has to be dealt with on your own land, and in a walled Wareham garden with neighbours either side that is not a formality.

Old walls. The back gardens in Wareham are often enclosed by old brick or stone. Paving laid tight against the foot of a wall like that traps damp in it and blows the bricks in a hard frost, so we keep a gravel margin along the base and let it breathe.

Materials. Riven sandstone and limestone sit well behind Wareham's period frontages and are uncalibrated, so each flag is bedded to its own thickness. Granite is the hardest, travertine the softest. Porcelain is calibrated, takes up no water and comes with a published slip rating, which counts on a terrace that stays damp.

Steps, edges and jointing. Steps of a consistent rise, a haunched kerb or a retaining course with a coping to hold the outer row, and joints brushed in with a two part compound rather than sand or a bagged grout, or hand pointed in a softer mix against old work.

Repairs. Sunk, rocking and lifted flags, a cracked step, moss and algae in a shaded walled garden, efflorescence and iron staining on new stone.

How it runs

Thomas comes out, takes a level off the back door and the damp proof course, and prices the patio himself. The written quote lists excavation and muck away, the sub base, the falls and where the water goes, edgings and steps, the slabs, and jointing. Thomas stays your contact while it is dug, laid and cleaned up.

In the old streets most back gardens are reached only through the house or a shared passage, so the spoil goes out in bags and every slab comes in by hand, with your floors sheeted along the way. On the estates there is usually a side gate and room for a barrow. Nothing is left as an open trench overnight. If the dig finds an old drain, a buried slab or roots, you are sent a picture of it with a price, and the dig waits for your answer.

A patio laid at ground level in your back garden is ordinarily permitted development, so there is usually no planning application and nothing for building control. A raised terrace, or a retaining wall taller than the usual limits, can change that. Dorset Council is the authority, and much of the town inside the walls is the Wareham Conservation Area, where anything seen from the street gets a closer look. The historic centre has a dense cluster of listed entries, and paving laid up against a listed building may need listed building consent. Some Wareham gardens near the river sit in a flood zone, and the government service will tell you in a minute whether yours does, which is useful before the levels are fixed.

Cost

Slabs are the cheap part: the rest of a patio price

Most of what you pay for on a patio never shows once it is laid. Carrying. Behind a house on North Street with a passage through, or a cottage sharing a yard, every slab comes in by hand and every barrow of spoil goes out the same way. A bungalow with double gates takes a mini digger and a dumper. That difference alone can outweigh the stone you pick.

The dig. Old concrete, a raised bed, tree roots or made ground are dug out and taken away by the load, not by the metre, and nobody knows the full depth until a test hole is in.

The step down. The finished paving must sit well below your damp proof course, with a gentle fall away from the house. Older houses in town often have floors close to garden level, so meeting that can mean a step, a retaining edge or a channel drain along the wall, and each one is priced.

Wet ground. Near the rivers the ground is alluvium that stays wet all winter and a lawn can hold water for days, while in the town itself it is mostly sand. A deeper bed of crushed stone under the slabs, a full wet mortar bed instead of dabs, and a fall to somewhere that really drains all cost more and last longer.

Any other quote should answer how deep the dig is, whether the slabs are on a full bed or on dabs, and where the water goes.

If it has become a hazard

A slab that has lifted or a step that has dropped

A slab lifted at one corner or a step that has sunk is a trip waiting to happen, and a patio that stays in shade all winter can turn green and slippery. Ring rather than use the form.

We can usually lift and re-lay the worst slab or step on the first visit to make it safe, then look at whether the base under the rest has gone. If water is standing against the house, tell us, because that points to the falls or the drain. Planned patio work runs Monday to Friday, 8am to 6pm. If nobody answers, we ring back as soon as we can.

Worth knowing

A flood zone is a reason to build low, not high

Wareham sits between the Frome and the Piddle, and parts of the town near the two rivers are in flood zones two and three. You can check any address on the government's flood service in a minute, and it is worth doing before anyone sets a level in your garden.

The instinct on a Wareham plot like that is to lift the patio, on the reasonable theory that higher is drier. It rarely ends well. Raising the surface moves the paving closer to the damp proof course, or over it, so the wall starts taking water from the ground. It also displaces whatever used to sit on that patch of garden, which then finds a neighbour's boundary or the wall of the house. And a raised terrace behind a period property is a very different proposition from a patio in planning terms.

What works instead is to keep the level low and design the water out. Take a proper fall away from the building, run a channel at the low end into a gully or an outfall that genuinely goes somewhere, leave a permeable margin where the soil will accept it, and use a jointing compound that will not wash out of the joints when water sits on the surface for a day. Then when the ground does get wet, the patio drains and dries instead of holding it.

Who you are dealing with

Patios inside the walls, in Stoborough and Northport

We lay patios in the town inside the walls, Stoborough, Northport, Sandford and out to Ridge, broadly BH20, under Dorset Council and 12.5 miles from our base in Boscombe. Our company name is Bournemouth Roofing & Building Ltd, registered in England and Wales, company number 15471719. Before you book a visit in Wareham, you can read our customers' Google reviews, word for word, on our reviews page.

Thomas Hannen owns and runs it, and he takes the levels and works out the price at your house himself. A verified Checkatrade customer gave us a 10 out of 10. The visit costs you nothing, nor does the itemised quote he writes up afterwards. Raising a front drive causes the same water trouble, and a driveway in Wareham is kept low and drained for the same reason.

Questions

Questions about patios in Wareham

My garden is in a flood zone. Should the patio be raised?

A raised patio in Wareham almost never helps. Raising it brings the surface closer to the damp course and pushes water onto somebody else's ground. Keeping the level low with a proper fall, a channel and a real outfall deals with the water without creating two new problems.

How do I find out whether my address floods?

The government's own flood service will tell you from a postcode, and it takes a minute. We look it up before setting levels on any garden this side of the bridge, because it changes what we would recommend.

Can a patio be laid against an old garden wall?

Yes, with a gravel margin along the base of it. Paving butted tight to old brick or stone traps moisture in the wall and the face spalls off after a hard frost. A margin lets it dry and catches the drips.

What jointing survives standing water best?

A two part brush in compound, properly worked and cured. Kiln dried sand washes out of the joints the first time water sits on the surface, and once the joints are empty the bed underneath starts going the same way.

Is there vehicle access for the materials in the old streets?

Sometimes not, and it is normal. Everything then goes through the house on boards or through a passage by barrow, and the pallets stay on the road for as short a time as we can manage. It is priced as its own line rather than absorbed.
