Gary, Thought you had gone walk about. Dead man. We use stiff concrete 450 wide and level from end to end down the edges, and possibly down the middle to split the bay and we screed of them. We use a 125x38mm aluminium rule laid flat and 900 bull float on 6m adjustable pole to finish.. As...

Aquapol is not a waterproofing solution for flat roofs, it is a completely different animal, however Aquapol do manufacture Cromapol Acrylic Water Proofing Roof Coating. This is a short term solution and carries no guarantee, and in our opinion is a waste of space especially over the top of...

Ronny, We do not believe we are wrong on this one, and you should know by now that we cover our backside every way but which. We did not mention any make of lintel, except for composite and non composite, how ever, on reflection, we do admit we should have said. (they are POSSIBLY non...

We often wonder just how much money people waste on working to a building notice, when neither they or their contractor know zit about construction or the BRs. Easy options first for you to put in front of BI for his approval. Repeat his approval. The list of Simpsons fittings that we will...

Sorry, but disagree with some of these posts. There are two types of concrete lintels and various grades If your lintels are two number 140x100mm deep then they are non composite lintels, and the reinforcement wires are approx 20mm up and 20mm down, so in theory it does not matter which way...

Sounds like the house that Jake built. Are you on full plans or building notice? From scant information provided, we can only give a scant answer. Assume it is a vaulted lean to with shallow pitch due to the fact that you have to get under first floor window sill level. We assume vaulted as...

101 is right it is Bungaroush shuttered walling and finished with a render. Only come across it twice in our lifetime, and first time we caught a cold on the work we priced, second time we run a mile when we saw what it was. Date of construction is right. Normally built of brick spread...

Sorry for delay in coming back to you. 1200 polythene okay. 11mm OSB okay Facias. Difficult to explain this. Cut joists to size flush with external brickwork Mark down end of joist 75mm and 200 back (if 300mm wide cav wall) Cut this out so joist sits on internal wall and 75mm end of joist...
