Traditional Hot Mixed Mortar Repair & Repointing of a Listed Boundary Wall<\/h4>\n\n\n\n

As with all old buildings and walls in Bristol the mortar of the time was hot mixed lime mortar mixed onsite from quicklime. <\/p>\n\n\n\n

For thousands of years this had been the principle binder for above ground building. <\/p>\n\n\n\n

Here in Bristol the aggregate was often a mineral residue by-product from the burning of coal, alongside grit sand with occasional specks of crushed brick. The mix varies from house to house and from one area to another. Some walls were historically constructed with an earthen lime mortar where the aggregate was primarily subsoil from the surrounding landscape.<\/p>\n\n\n\n

These samples visibly reveal the aggregates. The white flecks are semi slaked chunks of lime from the mixing process.<\/p>\n\n\n\n
