    More damp problems!

    If it's possible to safely do so, then perhaps post pics of the exterior wall, and the roof and parapet/abutment.

    RSJ to support rafters

    Others, with far more experience than me, might come along and perhaps have more definitive things to say about your proposal - but what exactly did the SE calculate? What is your project? Can you scan full section and plan views? How can "proposal 3" be viable if it's "not possible...

    Damp on inner wall...

    1. S&VP is soil and vent pipe - i presume that you have a double or single syphonic pan, which "S" traps into the floor? 2. Gulley, as mentioned above, only requires bailing out - container and sponge. 3. Why not buy (from screwfix) a 100mm or 150mm drain test plug, and plug the openings...

    Damp on inner wall...

    1. Perhaps some pics of the exterior showing the S&VP and inspection chamber. And the gulley with the bricks cleared. 2. Have you examined the gulley as suggested? 3. What part of this scanned plan is the extension? 4.What were the results of my hose blast suggestions? 5. Dont...

    Beam sizes for garage roof storage

    You will have to be certain as to what your intended use of the "loft" flooring is to be for. If you only store lightweight goods up there then it's possible that a 195 x 75 or a 220 x 50 @ 400 centres might work - with good end bearing. But do get a joiner or builder on site to give you an...

    Old painted polystyrene tiles used as wall insulation?

    woody, With respect, one can certainly re-use the p/tiles for the suggested use ( esp. as they will be behind plaster board), but, depending on the variables, there are several risk factors. Since the early 80's a fire retardent has been added to p/t's. How's the OP to know if his, stored...

    Corrosion issue in immersion heater

    Nige, I agree with your observations, except for regulating the industry - i'm dead against regulating almost anything. But to go to a trade counter and be,in effect, insulted by insolent, inefficient, ignorant half-wits is a common experience - and that after waiting in a computer-glitched...

    Damp on inner wall...

    We've moved from the single interior damp spot to various other areas, and now this gulley and drainage business. Perhaps you could post another scan of the whole house GF plan showing: a. all damp areas in red. b. positions of S&VP's and RWP's. c. position of gulley in question and...

    Beam sizes for garage roof storage

    The panel of brickwork that i can see between the garage doors, does that become a dividing wall that runs down the middle of the garage? Or is there a clear span of 16 feet across the garage interior?

    Working out the pitch of a roof

    FWIW: 1. take a min. 12" level and a tape measure. Stand some distance from the gable/verge. 2. hold the level at arms length while keeping it even. 3. eyeball one end of the level with the eaves. 4. determine the 12"point along the level. 5. from the 12" point measure up vertical to hit...

    Price of re-roofing a flat felt roof 1x3metres

    scottish slater and shirazman have my backing, for what it's worth. So many of the price claims on these forums remind me of the nonsense prices quoted on TV programs like "Homes under the hammer" Reality: 1. you initially view the job and quote. 2. return when accepted, and rip-off -...

    Old painted polystyrene tiles used as wall insulation?

    My two cents is not to re-use, or ever use, polystyrene tiles - in a fire they are a deadly smoke risk. Are you insulating for cold or sound? The pic wasn't informative - is it the correct pic? AAMOI: the skirting in the pic is carrying a 15mm supply to a WC (?). Why not use this...

    Cast iron soil pipe

    Noseall, I'm referring to the siting of the S&V pipe slap bang in the entranceway - there are a number of design issues there.

    Damp on inner wall...

    1. I'd hold fire on digging up the bush - there's no need. 2. I doubt that you'll have a long term solution, so: a. Research damp/dpc remedial work on this forum. b. hack-off and render up in S&L, keep render just above bitumen dpc. c. fit new, taller (5") skirtings, and fix above...

    Cast iron soil pipe

    Great job - well thought out and well carried out. What poor, original design - was this a pre-war, ex-council house?

    Damp on inner wall...

    1. OK, dont do anything that will disturb the brick just above or just below the Bitumen DPC - or you'll crack the DPC. 2. The "blocked gulley" -empty it and clean and dry it out so that you can search for any cracks. 3. What condition were the skirtings in? 4. Leave your test hole open...

    Concrete floor levelling / repairing

    If these are minor blemishes in the garage only, then why bother doing anything else? Perhaps chisel away any raw stone and then leave well alone. AAMOI: Where you dont have "edges" to tamp from then you fix battens to the wall(s) and work from the batten and a free edge if one's available...

    Damp on inner wall...

    1. I doubt that you have a "drain problem" 2. Perhaps remove the "bubbling skirting" and examine for rot. 3. The asphalt/bitumen layer might crack and crumble over time. Depending on conditions on site and how long it's been down. Does the asphalt extend across all floors? I'm not...

    Corrosion issue in immersion heater

    On balance, i'd go with the first reply of akward, that its an Earth fault. Failing to get a meter across it, perhaps the OP could Off all power, and physically check and tighten-up at the isolator, the programmer, and at the C/U. Is a water softener in-situ? Is there any galv. steel in...
