River wall repair using prompt lime mortar, Brigg
The historic river walls that run along the Ancholme through the center of Brigg were in much need of repair, however the water level of the river could only be lowered during the cold winter months.
This meant that the lower parts of the walls could only be accessed during this narrow interval of time.
These walls needed to be re pointed using a mortar that would allow them to breath but also set in the winter conditions
Cold and freezing conditions can cause problems for all type of mortar such as surface flaking, In order to avoid this a hydraulic lime mortar with a gauged addition of Prompt natural cement which gave a rapid set to the mortar before the effects of the cold could take place but maintained a breathability appropriate for the brickwork
