I see thanks, so by the same logic then stud walls must have a very very slight loading, if constructed very tightly. I find it all very interesting, I should have been a structural engineering.

Thanks Woody, I understand that trusses self-support. But imagine if I got a length of timber 1 inch larger than the height of my room. In the center of the room I knocked this timber in under a truss and on top of a joist. Surely now there is weight of the roof on this timber? Assuming the...

Thanks for the reply. I get so worried about this kind of thing. I'm even worried that maybe wedging the floor could cause the chord part of the truss to crack in extreme temperature conditions! My mind is a nightmare.

Hello, Sort of a theoretical question regarding roofs constructed out of trusses rather than rafters and internal stud walls. If the header plate of the stud wall is fixed to the trusses and the bottom plate fixed to the floor then does that mean that some of the weight of the roof is being...

Thanks for all the replies Yet again an example of cheap modern rubbish. You should see my father-in-laws Victorian manholes, with glazed bricks, to stop rats climbing I presume, works of art! So I guess I should expect some leakage then considering an inspection chamber base is only about...

Hi, Thursday during the heavy rain foul water was escaping into my garden. I found the manhole was nearly full and that water was getting out through a crack in one of the stackable plastic risers. The cause of the blockage is being sorted out by Yorkshire Water as shared sewers are their...

Is that right? £330 to line 6 meters of pipe? That seems very cheap to me I can't get a picture without ripping up some floorboards. It's quite a construction though supported on brick piers of decreasing height until it exits the house at the far side. Must have weighed a ton. Apparently the...

Hi, I have a cast iron soil pipe which runs under the floorboards from the downstairs toilet to the outside manhole, part of the pipe runs under the hall/kitchen for about 6 meters, it goes from the front of the house right the way to the back. This pipe then runs into a shared sewer which is...

I guess you are right, depressing though, what a world

Thanks, if it had been a 100 year old Victorian terrace I would not be bothered. But its only 8 years old and that's what annoys me so much! Its not quite the worst section, I would need to get the ladders out to take better pictures. I paid good money to what turned out to be idiots. So now...

Hi, I had an extension built in 2010 ago and I am worried about the mortar. In quite a few places the mortar has "pulled back" from the brick, in other places small gaps have appeared in the mortar and the mortar around the gaps looks rough where elsewhere it is smooth. Initially I was...

Thanks woody, yes I agree eaves tray are the correct way to do it. But I see plenty of roofs where the membrane finishes just after the tiles with no eaves protectors. If as you say the back surface of the membrane is absorbent then is it not possible for water to be absorbed back up beyond the...

I've just thought that maybe as the ends of the membrane have been exposed for 7 years then that has something to do with it? Maybe UV damaged or something?

Hello, While cleaning out my gutters the other day, just after it had rained, I noticed that the end of my breathable membrane was saturated. I can't see a lot of it, but because I have double roman tiles you can see between the raised parts of the tile. The roof is not leaking, its just the...
