Letters from The Chequers – Part 13
The Groundworks Nobody Sees
After the diggers, demolition and concrete pours, we thought the next stage might start to look a bit more like building. In reality, a huge amount of the next work involved digging holes, climbing into holes, laying things in holes, filling holes back in, and then hoping nobody would ever really need to think about those holes again!
We needed to consider drains, soakaways, water mains, retaining walls, inspection chambers, pipe runs, cables and services.
Not very glamorous, but absolutely essential.
One of the first hidden things we had to deal with was the collapsed manhole cover for a soakaway under the main car park entrance.
Because The Chequers had once had a huge car park, it also had a huge soakaway to deal with all the surface water.
We knew that once the main works started, there would be diggers, grab lorries, delivery vehicles and heavy materials coming and going across the front of the site.
What we did not want was for any of them to discover the soakaway the hard way.
So before we had even properly moved in, we rebuilt the brickwork under the manhole cover and made sure it was safe.
It is difficult to explain quite how big it is until you see someone climbing down a ladder into it. Of course Mark did exactly that!
In fact, Mark climbing down ladders into large underground chambers has become more of a theme on this project than either of us expected.
The drainage was another big part of the hidden work. A lot of it involved working out what existing infrastructure could sensibly be reused and what had reached the point where replacing it was the better option.
Some of the old drainage was ceramic pipework. It had clearly done its job for a very long time, but compared with modern plastic drainage the internal surfaces and joints were much less forgiving. Rough sections, old joints or small changes in level can give debris somewhere to catch, and once that starts happening, blockages become much more likely.
So we spent quite a lot of time examining old runs, checking where they went and deciding what was genuinely fit for purpose.
As with so much of the project, there was a balance.
Reusing something that was perfectly serviceable could save a huge amount of digging, time and money. But there was little point saving an old pipe if we were then going to bury it underneath a newly finished house or garden and spend the next twenty years wondering when it might cause us a problem.
One Sunday morning rather reinforced that point.
We discovered water backing up into the old gents’ toilets inside The Chequers, which clearly required fairly immediate action.
Knowing that, on a weekend, we could be waiting hours even if we managed to find a drainage company willing to come out — assuming anyone came at all — we borrowed some drainage rods from a friend and lifted the manhole covers with some trepidation.
I won’t go into the details here, but suffice to say I do not want to deal with another blockage any time soon.
Luckily, it turned out to be relatively simple. We rodded what we suspect was old debris in the pipe between the house and the main drain in the road, and the blockage subsided.
We then spent quite a while running plenty of water through the system to make sure whatever had been causing the problem had properly cleared.
And just like that, drainage unblocking was added to our steadily growing list of DIY experience!
The new water supply was another major job.
We had a lot of new plumbing and service runs to install, including a new water main running from the front of the house round to the back, where the new air source heat pump and hot water tank are located.
Normally, that would have meant another long trench around the front of the house.
Luckily, while investigating the old services, we found an existing pipe route that was no longer connected to anything. Rather than dig up the whole frontage again, we were able to reuse that old route to carry the new water main through. It was one of those rare moments on the project where something old actually made the new work easier.
After so many discoveries that had created extra work, it was nice to have a win.
There was also the power supply.
The overhead line needed to be buried, which of course meant another trench.
By this point, almost every new improvement seemed to involve digging another hole somewhere!
The retaining wall was another major part of making the site work properly.
It was not just a wall in the garden. It was part of making the new levels work, holding back the ground and allowing the extension area and the old building to sit together properly.
The internal floor had already been poured, then the foundations, and a few days later the external retaining wall followed.
For a while, the whole site seemed to be made of trenches...
Trenches for drains.
Trenches for water.
Trenches for power.
Trenches for services.
Trenches that seemed to cut across other trenches!
Far from making The Chequers look more presentable, we seemed to be making it worse by the day; the grounds looked better suited to trench warfare at times!
There were piles of spoil everywhere, open holes, chalk, mud, pipes, cables and uneven ground wherever you tried to walk, but at least it was dry.
For a while, it genuinely felt as though we were living in a moonscape.
Getting from one side of the site to the other meant constantly negotiating shifting piles of dirt underfoot and trying to remember which route was still passable that day.
We have been incredibly lucky with the weather. Most of this work has happened through a remarkably dry summer, which has meant the dirt has mostly stayed as dirt rather than turning into acres of mud.
We are very conscious that will not last forever.
Fortunately, bit by bit, things are now starting to go back where they belong.
Pipes are being laid, cables are disappearing underground, drains are being connected, trenches are gradually being filled back in.
But there is still plenty to do.
The retaining wall still needs to be faced with something rather prettier than its current industrial concrete. The path around the house needs paving. There are still piles of soil to move and levels to sort out.
And ideally we would like to get quite a lot of that done before the autumn rain arrives and turns the route around the house into a quagmire.
So we haven’t quite escaped the moonscape yet.
But at least we are gradually filling in more holes than we are digging.
And that is the strange thing about groundworks. They are noisy, muddy, expensive, disruptive and absolutely everywhere while they are happening. Then, eventually, most of the evidence disappears underground.
Nobody looking at the finished house will see the soakaways, drainage runs, new water main, buried power cable or most of the plumbing that consumed so much time and effort.
But all of it has to be there before The Chequers can stop being a building site and start functioning properly as a home.
