I and R Masonry Cob Repairs

Cob wall repairs, Render and Lime wash.

Cob walls are basically built with earth from the local area and need a breathable lime render with lime wash to protect them.
Over the years some Cob walls have been rendered in modern cement which does not let water out and can make the Cob unstable. Cement is also much harder and brittle than a lime mortar.
Lime wash paint can protect by being able to shed some rain and let any moisture escape through it as well.

Here the render is too hard and brittle for the Cob and has cracked and is falling away, allowing water in, but it does not let it back out which in turn damages the earth wall inside.

All we have to do is clean up and move on to the next section of this wall, and do the same on the other side.

Cob wall restoration near Salisbury

This is a Cob wall but has been badly repaired in the past, it has brick panels in areas. Obviously the Cob was too far gone and they bricked it up well over a hundred years ago. As the wall is listed we have to repair it like for like, except for the modern repair to the right. There is also very hard cement render that has to be replaced with lime.
Various stages of repair.

It was decided that we put a strip of herringbone brickwork in as it didn't match up for height either side of the gap for normal brickwork.

The cob is now rendered, we just need to lime wash it and put in a new oak beam to replace the rotten timber above.
