For anyone else in the same position I'd recommend buying the dedicated stuff, I was working with Classic bond and it was a different texture and colour to normal woodworking PVA, and went off a lot faster, was much grabbier than I had anticipated. Also for anyone doing membrane roofing for...

Yeah the PVA was grabbier than I expected so it flattened out OK.

I bought a membrane online 1.5mm grade and when it came it had been folded into 3 and rolled but when laid out on the roof the inner strip has stretched and is slightly wrinkled. I put some heat on the heavy creases alone the rolled edges and they flattened out OK but despite leaving the...

That's maybe a good point.

I thought that was just a minimum recommendation but that ply was better?

I guess it's partially to stop a leak from doing too much damage as you say and partially to keep atmospheric moisture out, the top would be sealed with adhesive and the sides and bottom sealed with paint/varnish.

I'm replacing a flat roof with new ply and EPDM rubber, I know years ago it was best practice to seal the edges of the ply with gloss and varnish the underside, is this still recommended?

Decided as I was forking out £500 on parts already I may as well buy the manufacturer glue, no point getting cheap on the details.

As long as possible, I'm really asking if there's a difference between the two or are roofing companies just re-branding generic glues with their own logos?

In other words standard PVA and contact adhesives or should I shell out and buy my glues from the same source as the rubber?

I'm taking a chimney breast out at home but the mortar is very soft and crumbly so I don't want to use a kango to snap the bricks off, it's a party wall and the last thing I need is cracks in the neighbours wall. I was thinking of getting a flush cutting wheel for my 230mm grinder and just...

I hadn't really considered that, I guess there aren't any odors on a storm drain, I was just replacing like with like as there was one there before. I'm a bit 50/50 on this though, on the one hand I guess a trap will simply attract debris that would have otherwise been flushed away, on the...

That's another alternative to going straight into the side, I'll need to pick a gulley and do some measurments. To be honest I was hoping there were channel drains that could connect straight into a gulley without any faffing around.

Always keep insulation dry as a general guide.

My parents have recently had a driveway laid with new drainage but I'm not too happy with one of the piping solutions the builders come up with. He's installed this in the driveway draining into something like this below it the sketch below shows it working in section. A few...

Thanks Jeds, do you mean different diameters of inlets or different positions?

I have a downspout that connects to a drain as shown in the images below, the downspout was misaligned and the water was running down the face of the house and into the basement. I was going to dig it out and re pack it in gravel and realign the spout but it's started to crack and break and will...
