Ok, thanks for shedding some light. SE's calcs doc states: 'By inspection provide engineering brick padstones under both ends of beam.' This spec applies to a 203x102x23kg UB steel, span 3600mm. One end of the beam is to sit on the inner leaf of an extension (thermalites). Other end...

SE has commented on plans to give load bearing beam '100mm bearing on engineering brick'. On a previous extension job I built up three courses of engineering bricks in a section 450mm wide, into the inner leaf block work to support a beam end. BCO didn't comment, so assume that was good...

...to elaborate, I'm currently adding an extension. On external walls earmarked for render finish, if I match positioning of drip bead as per the existing building, I will need to source approx 60 facing bricks to form the course between dpc and drip bead. Unfortunately my local builders...

My 60's bungalow has a few external render 'panels', I can see the drip bead is always positioned one course above dpc. Looking at neighbouring properties, the drip bead is at least one course above dpc too - sometimes 2 or 3 courses above dpc. All of the neighbouring properties have 3 or four...

Thanks for replies. Existing roof is 22.5 degrees at best, the concrete interlocking tiles have only a two and a half inch lap. Reading tile manufacturers websites there is no way this configuration would be recommended nowadays, yet the roof covering has been in place without any issues...

Have a proposed single storey side extension and due to the span (wall plate to wall plate 10350mm) the truss company drawing shows a pitch of 15 degrees, in order to keep the roof at/below 4m height (enabling permitted development). Found a couple of products suitable for this pitch but on...

...problem must have been with my technique when fitting the bung, getting it perfectly square inside the 110mm pipe before tightening. Test has held for 2 and a half hours now. After the first 30 mins water level dropped 2cm, then stabilised. I'll give it another half hour but it looks like...

Had a specialist in to do a full refurb / re-enamel on a cast iron bath at a previous property. He spent an absolute age on preparation. He used various attachments on a grinder and different grades of wet or dry. Applied the enamel, finally painted the underside with metal oxide paint. Looked...

Cheers for the advice. Reading through previous forum posts, seems it's not uncommon for a drainage system to pass a water test and fail an air test, with the major point of failure being the air test kit itself! Therefore not convinced of the value of heading out to buy a kit that might be...

BCO inspected today and passed the underground drainage system from a regs point of view, but advised I do a water test, as they will want to do the official drain test immediately prior to occupation. 10 linear meters of pipe runs under what will be a ground bearing solid floor, and he made the...

I'm attempting to water test a newly laid run of underground drainage, using 100mm stopper. However, I can't get the stopper to stay in place. Even when it appears to be rock solid, every time I fill the system with water the plug gives way after 10 mins or so. There is approx 16 linear meters...

Do BCO's expect to see the underground drainage scheme with pipes connected to the chamber bottom only, or should I do the base concrete and fit the risers before making the call for an inspection?

Have a 450mm plastic inspection chamber to install - does this need to sit on pea gravel, as per plastic pipes or should it be bedded onto concrete? Also, what is the exact spec for bedding/back filling plastic underground drainage pipes in a trench - 100mm pea gravel bed, infill either side...

...as I thought, cheers for confirming. Due to the nature of the site (sloping) and a relatively high dpc on the existing structure, any foundation concrete will be covered in later stages of the project by slabs for a patio / path etc

Have 1000mm deep trench excavated in prep for full fill of concrete. The groundworker is of the opinion the fill must stop 100mm below ground level at the highest - however, I used this method once before and filled right up to ground level, the bco didn't complain. Has something changed in the...

Many thanks for clarifying Noseall. I've seen hardcore/concrete/insulation/sand&cement screed spec'd so many times now that I assumed the screed was part of the regs!

Looking at the regs, there are several diagrams for solid ground supported floors, one of which illustrates ground supported floor construction being (in reverse order): 1. Compacted hardcore (max 600mm) 2. Sand blinding (min 50mm) 3. DPM 3. Rigid insulation (min ?) 4. Concrete (min...

...bled all the rads a second time, drained a small amount of water out of the system via the boiler mounted drain **** on the heating return side, powered off and on again (with the heating switched to 'fully on' position) and let it run through the power up cycle... The hot water now works...

...apologies for hijacking an old thread... I'm getting the E10 error on a remeha avanta plus combi boiler. The pressure in the system is fine. On power up and reset, it works through the system checks for 2 or 3 mins, tries to fire up for a few second and then goes quiet, begins to issue the...
