I have a lot of builder's sand left over (about 800kg), which I have been using for bricklaying. Would it be possible to use this in a concrete mix (along with aggregate)for in-filling the two skins of a wall and some hollow brick piers? I think I am supposed to use concreting sand, it's just...

Hi, hoping you can help again! What specifically should I use for weep holes in a retaining wall? Someone mentioned copper would degrade, albeit over a long period of time. So shall I use the equivalent plastic pipe used in plumbing, or a type of waste pipe? And should there be some kind of...

Hi, you guys have helped me so much in the past, I would love your advice again. You may have seen my latest project: http://www.diynot.com/forums/viewtopic.php?t=31272 and http://www.diynot.com/forums/viewtopic.php?t=31163 Thanks to all the advice on here, it is coming along...

He?!?!?!

Thank you thank you thank you. I checked this thread before I started this morning, and so have been doing them the correct way up. Yes, I found it a lot quicker and easier and tidier! So is this any better? - all tips and comments gratefully received!

Ah yes, I have been doing them upside then. :oops: Although I have been religiously fillling the frogs with mortar beforehand. I thought that'd be best 'cus I imagined air pockets expanding and contracting with temperature and causing cracks and stuff. I am halfway through another one now...

Thanks for the tips. Yeah I used compressed air to blow the dust out. I did do 150mm so that's a relief. Thanks for the tip on the weep holes - I will use plastic then. Thanks also for the tip on the drain pipe. I will use smaller than 20mm then - I got that from Can you tell me...

I will be inserting weep holes at 1 metre intervals made from 22mm copper pipe at a slight angle, and have left a gap to put some land drain pipe down the back. Both these at an angle so that pressure is relieved. On top of the land drain is going to be 20mm gravel. Plastic sheeting between...

Thank you. Job done!

Really? Goodness me. Those wall starter kits aren't cheap and I have loads of ties left over. Oh well, I can't return the kits now!

A retaining wall as detailed in http://www.diynot.com/forums/viewtopic.php?t=31163. Yes, I looked for concrete epoxy at screwfix to no avail and have asked at my local builder's merchants but I get blank looks off the staff who work there. Maybe I am asking by the wrong name. What should I...

Thank you for your replies. Yes, they have been lost slightly over courses. The blocks, as will the bricks, have been bonded to the piers using similar to these http://www.screwfix.com/app/sfd/cat/pro.jsp?id=41311&ts=28666 and I inserted wall ties as I went up similar to these...

If I wanted to insert a metal rod (12mm diameter) into some concrete, what would be the best way? Drill the hole, fill with some kind of sealant, stick rod in? Or drill the hole, just insert the rod? It is in a foundation, which is going to have concrete poured on top between two skins...

Hi, I'm hoping you can advise me best. I've never attempted bricklaying before, but circumstances dictated that I had to. I have built several columns in my garden for a large retaining wall (all columns 450mm square and 13 courses high - course gauge stick taken from house) PLAN VIEW...

Hi thanks for your replies. My email has been funny so I apologise for my tardiness in replying. The building inspector is involved 'cus I did him a favour with something, so he is advising me, even though the wall isn't part of the house. As I was asking around about this, no-one really...

Hi, I love this site all you guys are great!!! I am hoping you can help me with a project I’ve got to do. I’ve got to build a wall in my garden. I have dug the footings 18m long 60cm wide 60cm deep. The building inspector said he wants reinforcing bars running along these footings. As I am...
