I've got a poured concrete subfloor in my extension which has a height variation of 20mm over a distance of 3m in some spots. there's a layer of PIR insulation to go down before UFH pipes and screed. It's about 27sqm area all in, so that makes for 0.25 to 0.5 cubic metres to fill (depending on...

Found this whilst excavating for another reason. Not sure if it was my digging that did it or not. It's fairly well embedded, and there's little wiggle room. It's carrying kitchen and utility waste, so not high volumes like from a WC. Replacing it will be a chore. Is it likely to cause issues in...

oh well that's embarrasing - I'd checked a few radiators on the stelrad website and there wasn't any mention, so assumed (wrongly) that it would be the same for their distributors.. As you were, and many thanks.. :)

If I know the physical dimensions of a bunch of steel panel radiators (cheap, of unknown origin) , is there a basic rule of thumb I can use to work out the approximate volume of the system (I'll take some rough measurements of pipe lengths and sizes).. ? So far I've seen 6l/kW and 11l/kW from...

There was a blocked rainwater gulley on other side of the wall, which I think added to the pressure under the slab. since the gulley has been cleared the area hasn't flooded and the inside is dry as a bone. The water was pooling slightly deeper in a low spot towards the centre of the room...

Hi all, Can anyone recommend a product that I can use to repair/seal the DPM under a concrete slab where the drains and some electrical duct pass through it? I know there's a weakness in a particular location as we had some localised flooding outisde due to heavy rain which then appeared...

In fairness, the bricks are pretty tough, I've killed a few decent smaller SDS bits in this house already. I'd rather kill a cheap core drill than an expensive one.

This is the kit I'm using: Screwfix/Erbauer core drill kit I wouldn't entertain using the pilot drill for much, given it's only a taper fit. I'm drilling into underfloor cavities, so tidyness isn't an issue, though previous holes have turned out quite neat, I assume its a feature of these...

maybe I'll back off a bit. Erbauer don't really state a speed, which is irritating.

@johnny2007 - my Bosch has a clutch, so no worries there. I guess the issue is what speed is considered slow. My drill has a 2 speed gearbox, as well as the trigger speed controller, so I usually run it on the lower speed (1450rpm) but usually flat out. @opps I tend to pre-drill, my set comes...

I bought a cheap one from ebay on a recommendation. It's a proper faff to set up, and doesn't quite fit on my old draper grinder unless I leave one of the securing screws off, however combined with my trusty and abused Henry vacuum, it makes a notable difference that is worth the grief. The...

Hi all, Any tips and advice for diamond core drilling? I'm in the process of putting a series of holes in the walls of my house for pipework for my extension, I'm using an Erbauer core drill set, with the 52mm size, and a Bosch PBH3000 sds drill (obviously not in hammer mode) with a max speed...

that's okay, the lights are still up :LOL:

Hi all, I'm looking to get my boiler moved up into the loft of a new extension, on the gable wall. Also on the gable wall I want to install a tv aerial - it'll be high as the aerial will need to 'look' over the apex. I'd prefer to get the tv aerial up into the apex too, and my OCD will want...

that might be worth a shout, especailly if it's more rigid that drain rods, which I experimented unsucessfully with this afternoon..

Access from upstairs windows is limited, desks and such in the way, windows don't open that far and there's still reach issues. I tried earlier with some drain rod, which I can get into position on the lower sections, but fine control is next-to-impossible, and it's very challenging to get near...

Interesting my original clamps have quite a coarse a square thread, but the new ones I got from screwfix are a regular metric 60degree thread. it will be interesting to see how long they last. I've also got a bearing sleeve and compression set with M8 M10 and M12 threaded pullers - all are...

Thanks all - I got a set from screwfix in the end, they don't offer much more offset that my current set, but having a second set mean I can reposition one clamp if needed without things getting all bendy-weird.

Houses this time of year are a spectacle of lights and decoration. Mine isn't. It was but then the rope-light I'd carefully installed last year has started blowing fuses, so I suspect it's past it's best. It's hung from the soffit of my front facing gable wall on hooks. It's quite high 7m ish...

I'm not sure if you've mentioned the materials the house is made from, of if there's evidence of recent(ish) work - particularly drilling or cutting the fabric of the building. In my own experience, black dust can be from the block/bricks in the wall, my old place was terrible for it as the...
