Can anyone help please. I have had lots of emails about the dpc cavity
tray. The only thing is when I remortar the joints on the horizontal cuts
between the bricks, do I just fill it with mortar? or should I pack the
joint in places with slate or similar as well? The cuts will be 2 metres
Many thanks for help.
On the horizontal beds, just fill with mortar, on the perps (vertical
joints) leave one unfilled per tray to let any water escape.
If you are asking how the trays are fixed (presuming that they are lead) ,
then what you do is fit a couple of lead plugs per tray, hammered into the
joint on top of the tray so that these are just below the surface and then
repoint the joint as normal.
