I am looking for technical information/experience to share on how to tackle damp rising in old historic buildings. Construction of walls in stones held together with mud and lime mixed mortar. During rainy periods water table is almost above foundation level.
Existing building has neither damp proof membrane in the floor nor damp proof course in the walls. The building is a 2 storey structure about 80 years old.
I have used a combination of French drain to lower the water table and applied a low viscosity epoxy pressure injection resin (Sika Product) to the walls for forming a barrier against infiltration of ground water. The mortar for plastering walls had waterproofing admixture. The plastered walls were than treated with a water dispersed epoxy resin coating. The ground floor slab was touched with new screed having a waterproofing admixture. This has helped considerably.
