    dot and dab wall sealing

    hi , can you just dot and dab straight onto bricks and low suction blockwork ? i have seen plasterers do it but looking online its a mixed bag of ideas ? also why are the boards not put direct on the floor ? is it for rising damp ? cheers

    rendering concrete blocks

    hi, walls are just built, so no moss etc on em, no splits or cracks, 50mm full fill cavity with knauf waterproof insulation, dpc at start of first block so i will leave a small gap from top of dpc to start of render. wall is only 2.1 m high by 3 m so not big hope thats enough info ? also do i...

    rendering concrete blocks

    hi all, i want to render an external concrete block wall i have built, what mix do i use ? its a cavity wall so do i need to add a waterproofer ? how long between coats ? also i was wondering if i used a 5;1 mix for the blockwork would a stronger mix of render have any effect on the blocks in...

    shock risk

    ok makes sense, anything connected to the earth ie a metal pole would become live under the fault , and if that was touched while stood on the ground a different potential could exsist so shock risk would be higher ?

    shock risk

    could someone clarify this for me - a live 230v main feeder cable becomes faulty and becomes in contact with the ground which im stood on, this cable is straight from the supply transformer and fault occurs before main cut out. would i recieve a shock due to my feet been apart creating a p.d ...

    air bricks

    thanks for the link, but my conservatory floor is suspended timber not concrete so that will need venting to, question is do i need to vent the exsting house air bricks to the new external wall, like in the link photos , then add more airbricks to vent just the new cony floor ? or can the house...

    air bricks

    hi, my house does have 3 more down the side and two at the front, my post prob want to clear . so if i let the two vent under the cony suspended floor and add two or three air bricks into the new cony wall would that do ?

    air bricks

    my house has two air bricks which will be under the suspended floor of my new conservatory, can i just put air bricks in the new cony wall to allow airflow or do i need to duct the house ones outside and add new ones just for the cony suspended floor ? thanks

    electric shock voltage levels

    just wanted to say thanks for the answers to my post especially paul c for the detailed clear answer its all become clear !!!!

    electric shock voltage levels

    if they meet the zs tabes they ill clear the fault but my query is for thesplit second it takes to clear the fault what voltage is present on the mettle case ?

    electric shock voltage levels

    could anyone explain the potential divder earth part, which means half supply voltage is shown at the fault ? in either case of 230 or 115 volts at the fault is that saying i would recieve a shock at one of the two voltages but if lots of fault currunt was to flow i would be ok as the shock...

    electric shock voltage levels

    so if the resistance is unequal it could be higher or lower value of voltage ? also how does the touch voltage 50 v max work if i touched the kettle and say a metel tap at time of fault ? thanks for the anawers
