I thought I was looking at the London Underground map.

A mate of mine got rid of a lot of the subsoil down a well in the garden. Not sure if it was in the contract. The rest he got rid of in Tesco carrier bags, leaving them on the bus home every night. Agree the builder must be a cowboy though. A decent pro like me would take away and dispose of it...

Have a look at Brickhunter library. There's thousands on there, but being 50mm and textured will narrow it down a lot. They might be on there, but not in production. Google Imperial Tudor Multi.

You need lateral restraint straps.

You just need a small hand held one. They just give you an image of the wall, with different colours showing the warm and cool spots on the wall. They work better when the inside temperature is a lot warmer than the external one.

A 1/3/6 OPC/sand/gravel used to be a standard mix for a lot of residential foundations. 1/2/3 is really strong. 1/2/4 was normal for insitu lintels.

Octopus are taking bookings for next winter 2026/2027 in the new year.

Remember an S/S liner is a temporary liner which although can last 25 years can be wrecked in only a few years if burning the wrong fuels on a slow, cool burn.

Most tradesmen don't like saying an old flue is OK. If you do a sealed smoke test, the regs allow for a small amount of smoke to escape. The amount is left to the experience of the tradesman. The majority of people are not going to get involved with this in an old flue, especially as it could...

^^^^^^^°°°° This The idea of insulating the inner reveals is more about getting enough insulation to stop condensation forming and mould growth.

There was never a 4 year rule for regs. That was only for planning. It used to be one year for an enforcement notice to be issued to the home owner from date of works completion.

Look.into the way paving slabs are produced and the materials used, as it's similar in that it's thin concrete in a mould. Paving expert website will probably have some info on the subject.

Standard plasticizer is mainly an air entraining agent. When mixed up properly, it keeps thousands of tiny air bubbles in the mix which act as mini ball bearings and make it workable with the minimum amount of water. Without it you need more water which weakens the mix. It's especially important...
