Today, they applied.... I don't know what it is, some kind of concrete mix to the walls, covering the bricks. Also, they pulled some more plaster board off the opposite wall and around the sliding door and then applied the same stuff.
It turns out that the area around the sliding door was completely filled with a hydroscopic filler that was totally inappropriate and that may have been a big part of our damp problem. They dug it all out and refilled it all today.
Tomorrow they'll do the ceiling and install a vent in the wall, and do the first coat of the damp-course.
The stuff they use for the damp course, I'm told, is the same as they use in the Channel Tunnel. So, if there's a tsunami or floods, we should run into that room and we'll stay dry.
Flooding is on our minds because there's flooding all over Sussex today, and more to come, say the weather reports. Rain and floods, a perfect way to spend a vacation.
