Progress on the garden wall

The wall is progressing at a slow pace. I’ve built the back of the wall up to 9 bricks just to see how it will look. The stretchers are the original bricks turned around and look a bit white at the moment as they’ve had lime on that face. They should become more colourful and blend in after rain cleans the bricks.

The original bricks are Bedford Clamps – they have a distinctive raised line along the stretcher face where the bricks were stacked after moulding which adds texture to the wall. They are slightly curved which adds further texture. I’ve been setting out from the new bricks I’m using as headers as they are much more straight.

The pointing is the same as the rest of the house. It is trowelled flat, then after drying for a few hours struck with a masonry cleaning brush, then lightly brushed. The brushing recesses the pointing exposing the edge of the bricks and some aggregate in the sharp sand.

I’m speeding up. My record is 120 bricks a day so far. But it’s been very wet at the weekends so progress is still slow.

The rain helped make sure the coping and drip tiles work on the test wall. I’ve picked up 260 half round bricks from a wall that had fallen over in Nottingham.

I messed up on the join to the old wall. I built the pier 1/4 brick too far along because I was working off foundation bricks that weren’t aligned with the wall. I adjusted the third course to compensate.

I compensated in the wrong direction and that caused problems with the joint to the pier so I’ve removed one of the strange double headers from the original wall and now I’m 3/4 brick out on the fourth course which gives me a better bond with the (redesigned) pier. Most of the misaligned courses should be hidden underground so it should look like I messed up once not twice. The transition from the existing wall is now seamless.

Starting the garden wall build

This is the biggest build I’ve attempted by myself. I’m guessing it will take 6 working weeks. I have a couple free weeks so have started laying bricks in the two courses below ground level. Laying out and setting heights has taken some time, but things should speed up once I have a straight level run to build on.

I built the corner at a measured distance from the existing wall, then laid the bricks out dry using a brick gauge to make sure I don’t end up with an odd size space in the middle somewhere. That’s worked well – I can remove a couple of bricks to mortar them in, then check the spacing is still OK before removing any more bricks.

The hessian is to keep the sun off during the day and the frost off during the night. Perfect lime building weather would be much more overcast but I’m getting a good tan at the expense of a lot of covering and watering of bricks.

The old wall was very badly spalled and only half the bricks could be saved and even those will need to be turned around. No problem I thought. I bought the same again in reclaimed bricks. But they aren’t a perfect match. They look OK as headers, but headers only make up a third of the brick count. I can lose a lot of the new bricks in the foundations, and I think it looks OK if I keep using the new bricks one brick above ground. I made a spreadsheet to work it out and have been trying all sorts of ideas.

The wall has 4 piers on the long face sticking out by a quarter brick both sides to match the original. The piers go in last to avoid disturbing the string line.

I had guessed I could lay 100 bricks a day and managed 80 bricks a day on the long straight run. I will hopefully speed up on the next courses as bricks below provide additional reference. Each course has 190 bricks so it’s not going to be a quick build.

It’s useful to have a couple of courses below ground level. It took me a couple of bricks to get everything straight and level and most of the pier positions shifted very slightly while I found out what mistakes I could make with brick spacing. At some point they will need to go up straight.

Garden wall foundations

The garden wall was delayed into the winter while a tree stump was removed and it’s getting warm enough to avoid bad frosts now. I spent a day figuring out levels and worked out that a 450mm * 450mm hole would be about fine everywhere. Planning 300mm concrete then a couple of bricks up to ground level. I don’t know exactly how tall my wall will be, but guessing I’ll run out of bricks between 1.2m and 1.4m.

A man with a digger got the hole dug by lunchtime. Ripping up the old foundations made the hole a bit wider than intended.

The ground levels step down by a couple of bricks at the corner of the wall. I’ve put formers in to make the drop one brick at a time. They aren’t where I intended as it was easier to put them where there were banks either side to drive stakes into. There’s also a bit of shuttering at the side of the hole where the tree was.

The vertical stakes indicate the level of the top of the concrete which is a couple of bricks below ground level. They don’t look level in the photo as they go squint when you hit a stone, but they should be accurate for height. They all go into the ground more than 200mm which is useful as you can’t see them when the concrete is poured and they get knocked with the rake.

I used a mix on site concrete truck. They started off with some fairly firm concrete to dam the level changes and then filled the trench up with the normal runny concrete while I raked and tamped behind.

It’s mostly worked. The foundations start 1/8 inch high, then fall 1/4 inch low for a good length. Also one of the dams is leaking very slowly and one end has dropped by 1/2 inch. I’m hoping when the concrete gets around to it’s initial cure it will put a stop to that. We’ve been having light frosts so I’ve covered everything with hessian and can worry about it later.

The first bricks went in a couple of days after the concrete pour. The existing wall leans a little and I didn’t have a good reference for the new wall as it starts off lower down than it used to and there is a slight change in direction. The existing wall was awful to set out from.

The cunning plan is to build a pier after these bricks. I can set the wall out nice and straight from there and also blend the old wall into the pier.

Garden Wall Bricks

2000 bricks arrived for the garden wall last week. I also saved 1500 of the original bricks. Now I have a lot of bricks.

I had planned to use new bricks but the lead time is too long at the moment so I went for reclaims. The bricks came from Loaded with bricks in Birmingham and just about all of them look useable which is surprisingly good for reclaims.

The size and colour of the new bricks match the original bricks well. The originals are Bedford Clamps and are rare these days. The texture doesn’t quite match. but once there is mortar in there nobody will notice.

I’m planning to use the new bricks as headers and the original ones as stretchers (as the photo below) so I can retain the stripe of Bedford Clamps and also hide their spalled side.

Next job is organising a hole for the foundations and getting the concrete poured. After that I should have a nice relaxing job laying bricks for some time.

Tree Stump

The lean in the garden wall seems to have been caused mostly by a Leyland Cypress tree removed in 2014.  The tree made the wall lean over by 6 inches and also pushed the foundations sideways by around 8 inches.    If we are going to have a straight wall there will be some stump removal needed because the stump is in the way.

It’s been a nightmare to try and organise the stump removal and work has stopped on the wall now.   The tree folk are really busy after having been stuck at home earlier in the year and despite promises nobody seems to want to actually turn up to remove the stump.    It is too close to frosts to start re-building the wall this year.


More than a month later the tree guy turned up with a stump grinding machine and (very professionally) removed the stump.


Now the awkward stump is just sawdust.   There is quite a lot of sawdust but November 5th isn’t too far away and might provide a good excuse for a bonfire.


Starting the garden wall rebuild

I’ve been measuring the lean of the garden wall every year.  The lean has been increasing by about 1/8 inch every year, and it’s reached 6 inches now.  There doesn’t seem to be any good reason for the wall not falling over, and given the lean is over a footpath it’s probably time to do something about it.

It’s an old wall built with Bedford Clamp bricks in Flemish bond.  The gable end of the barn was built on top of the wall, and the barn is from around 1850 so the wall is probably earlier.  Bricks are a funny size so guessing Georgian.  The wall will be rebuilt using the original bricks.   It’s been repointed in cement so the bricks are horribly spalled and will need to be turned around.


I’ve been sensible for once and installed some temporary orange fencing.  I feel it says ‘stay well back  – there are some highly trained professionals doing serious stuff here’.  Also it’s nice to have some sort of fence while the wall is missing and when the foundation hole appears.  Though the first couple of days will be vegetation clearing on the other side of the wall.


The poor wall is looking less well now.  Nominally the wall is straight (in hindsight there must have been a bend roughly where the tree was), but it has been pushed sideways and over by a Cypress tree.   If it falls over now it will result in ankle bruises rather than squished children so I’m feeling a bit better about it now.

The bricks were very badly spalled.  We’ve been cleaning up the bricks as they were removed and where the wall hadn’t been repaired in cement the bricks can be turned around and used again.  But many of the headers are spalled at both ends and are too short to be useful.


There are 1000 bricks in the stack so far. The wall had been repointed in white cement which is probably what caused the spalling.   The top couple of courses and parts of the piers had been rebuilt in cement and not many bricks were salvageable from that.  I’m going to be 1000 bricks short.

It will be a happy wall again, rebuilt in lime mortar that will last for hundreds of years.


At the rear of the house facing the 1970s bungalows a large stretch of wall was replaced with fence in the late 1980s.   It turns out that the bungalow site was levelled to below the wall foundation.   The bricks don’t reach the ground.  The foundations were 6 inches thick so did make it to the ground, but they weren’t designed to be exposed and went crumbly.
