    Hi, doing some work around the site and building a large she'd. Block layer had built on top of steel lintel. Is it correct to just put the DPC on top of the steel lintel then bed mortar off it for the block or does it also need it under the DPC aswell. Afraid it'll be a weak joint along top of the lintel.

    Pics later.

    I'm not a builder but I'm not sure what a dpc would do above a steel. Unless you mean a cavity tray?
    Either way gravity should hold things down, if it is an unsupported parapet or similar then you would need to strap it down in some way.
     
  4. Presume it is a dpc tray , but I think they are just asking if the dpc should be sandwiched between mortar on top of the steel lintel .
