We were given the task of reinstating a wall that had collapsed due to a flood some months earlier. As the wall made up part of a listed estate the brief was simple. The wall had to go back using very specific materials and quantities.
The Scottish lime trust were asked to take a sample of the original mortar, and from there we were able to source the best matches available. This included sand from a specific quarry, then mixed with a course aggregate to specified sizes and quantities and finally using an appropriate strength natural hydraulic lime to bind the mortar. Before work could begin reinstating the wall all safety measures had to be taken.
In this instance this included acquiring the correct permits and the installation of a traffic control system. Once all this was in place the wall was then constructed using traditional tools and methods.
