So Saturday (24) came along and I was up early once again. During the last few days we had discovered that the dampness in the bottom of the cupboard in the gym we have been decorating wasn’t drying up. It had to be caused by an ingress of water from outside the building. I had given it a few days to dry but it stayed wet. Two things are at work here. Firstly, the house walls were not constructed with a damp-proof course or membrane and secondly, the boiler room floor is below the ground level outside. I have no real idea why when it was laid the builders made it so. The house was built in 1877 but a quarter of the boiler room being part of an extension built we think at the turn of the century, that is 1900, was added to the already low floor. It is the only room below ground level at the rear of the house though at the front the rooms there are below ground only because earth was piled-up in front of the house…
There are vestiges of former windows below the soil level which have been bricked in. I suppose the thinking was because the ground the house stands upon is sandy there was enough drainage as not to become a problem. Anyhow on Friday I got to thinking about what I could do about the ingress of water and from where it was coming. When I took measurements I discovered that the floor inside the cupboard was nine bricks down from the window in the room but outside only seven courses are visible above the path and eight just where the wall ends at the grid. Now the grid is below the path so it puts it at the same level as where the dampness appears inside. On checking the brickwork I found gaps in the mortar at ground level and especially around the grid. I decided to mix some fine cement and use it to seal off the gaps both along the base of the wall and around the grid earthenware.
Saturday and Sunday were forecast as dry and sunny and as I write this on Saturday lunchtime it is indeed sunny. It needed to be dry at least so the cement can set.
