It's for 2 things, first as part of a wall render to which a heavy duty hinge will be mounted on and second to mount a lintel on top of a wall but it needs strength to stop teh wall moving at the top due to the weight of a (v.heavy) door

How do I get the strongest concrete mix - Is there a stronger mix that the 'strong mix' on the bag? If I mix concrete with water only will that be as strong as possible? I also need to drill through whatever I make so can't have it diamond like...

I'm rendering a wall with a concrete and hydralime mix plus concreting in a lintel above a garage door - the lintel sits on top of a concrete block wall. The problems are the lintel got knocked (upwards) by the door - didn't think I hit it that hard and it seperated the lintel from the...

As it's for an external wall should i use hydralime? (sorry to previous respondants I did't mantion it was external). If so where do you get the stuff - bnq don't sell it.

By the way this is for the external side of the wall - is that still oK?

thanks!

I want to cement render part of my garage. I have some basic questions: Do I need to use hydralime as per the rendering spreadsheet stikied on this forum? - what is it, what does it do? Is 20mm a good thickness to work to - I was thinking 10mm would make it flush and fit in with...

Hi - why are you recommending taking pictures - for a buildling inspector or electrician to sign it off or then do the work himself?

Having just built part of a garage extension in large concrete blocks I can agree with the above - mine is a bit wonkey (not too bad though) and you learn as you go. My advice (purely amatuer) since you sound keen and need to save the cash why not do the course, buy a load of bricks, make a...

Tried it I make no progress at all like that

The bits are good quality and I believe tungsten carbide tipped. I don't know if a brand new bit of the same type would be better/faster - maybe worth a go? The smalest bit I have I think is 6mm what size pilots were you thinking of? I have tried all different sized bit - there didn't seem...

My garage is made of prefab concrete and I want to drill the walls to put some screws in the wall (so not drilled all the way through). The problem is the concrete is very tough and has lots of small stones in which seem to be even tougher. A normal hammer drill makes little/no progress...

How does that 'mole' in the link work? Would that be easier than digging a trench? Any ideas on rough prices for an electrician to design and then check the installation if I do all the work?

Conduit would be if I need to run additional cables in the future it would be easy to do - e.g. alarm, telephone, doorbell etc.

Do I need all the books or just one, where you mentioned I should get a guide to the regulations (3rd book) is that not what the second book is also? Which book would be recommended for a DIY installer - would I find out in there if its best to have a RCD feeding the entire supply or one in...

What are my options for doing this? Are there any guides? Can I use galvanised conduit instead of armoured cable? - how deep, size, connections? etc Any tips? How much current (cable size) should I plan for - I'm estimating the max I could use would be around say 13A...

Yes it's good though I wouldn't necesserily recommend the Danlers over a cheap one from ebay. Since i've had a couple of problems with the Danlers - it doesn't stay on for as long as it used to plus draughts switch it on because it's designed for false ceilings in offices where there are no...

I would like to build a wall using concrete blocks/bricks and sand/cement mortar but is this a no no in winter, how long of a dry spell do I need after building? Will temps be a problem? Thanks

Digging the outlet up is a lot of work, plus I'd have to pay to have the whole lot re-tarmaced. What got me was it felt as if the casting for the ceramic drain had no exit in the first place I would have thought if a builder bodged the job the drain would have an outlet it would just go nowhere.

would that be say 1 normal size bucket of sand/cement and add 1/2 a thimble of washing up liquid? apologies if I've got that comically wrong!
