There is a forecast for several inches of rain between Thursday and Sunday here. I am in an old brick home with a sandstone block foundation. The soils are clay in this area.
There is a rather large stair-step crack in one of the front bedrooms, it seems to open up by a fraction of an inch every time we have a large rain event. Due to recent drought, the front yard is mostly bare soil, that is very hard and dry. There is a slight downward slope, from the street towards the backyard.
I am concerned about the soil absorbing moisture and causing more cracking. Is it feasible to use heavy-duty tarpaulins to try and minimise the amount of soaking of the soil? I have been told I am an absolute nutter for even thinking this.
