Well the DPC is a floor level so i presume that what i said would be correct ??

Just a quick one for you folks, at the weekend i am going to be building an internal block wall, it will be on a concrete base, my slight concern is that this is near the kitchen and there is slight signs of damp on the kitchen floor. Should i put down a length of DPC on a slight bed of...

Hi guys, Just a quick one, what is the procedure for changing an emersion heater in a cylinder ??? After the electrical side does it just need unscrewing and do i need anything special to seal the new one other than the sealing ring, as i have seen a lot with gunk all over them.

Cheers Woody I have seen them before in the screwfix book but was just a bit unsure as to wether it would go down the cavity far enough.

Yep i know exactly what you mean thanx Woody, do the periscopes extend a decent length because im presuming that the 100mm pipe will go in at hard core level, is that right ???

I agree with all the above comments, i have never asked any of my customers to do anything like that before, sounds to me like you have a DIYer that wants to be able to plaster and when he has come to start he has realised the enormity of the task at hand. Get rid and get somebody who knows...

Hi Folks, Sorry to bother you again just after a little more info, What is the difference between an aerated block and a standard dense block ??? and is a 'Class B' engineering brick suitable for below a DPC ??? Many thanx in advance Stan.

Hi Bengee Yes you do need to notify BC of any changes to windows as you will need building regs, its a flat fee and they will come out to inspect as many times as required, you will also be able to contact your BCO whenever you need help as well.

Just out of pure curiosity, How much plasterciser should you use with a mix of say 1:1:6 ??? are we talking about a mugfull, morre or less ???

Thanks for that woody, i was going to use standard blocks with a 100mm cavity and around 75mm kingspan insulation.

thanks for that noseall, What is the lime for ??? is it just to allow slight movement in the mortar ???

Hi guys i have searched for this answer but am unable to find it, i am building an extention out of blockwork above dpc and engineering bricks below dpc, my architect has detailed that my outer leaf should be laid in 1:1:6 mortar. What does this mean, i can appreciate that the 6 is sand...

I am currently looking at building a small extention myself, i can do most things so thought i would give this ago as well, (watch out for me on 'honey i ruined the house') :( i intend to use engineering bricks below the dpc and blockwork above that which wil then be rendered inside and...
