Caption: Specimen of Waterholes sandstone from Crossland Hill, Huddersfield, West Yorkshire.
Description: Sample of Waterholes sandstone from the building stone collection of the Edinburgh World Heritage Trust. The stone has a cut surface with a pale orange brownish-grey colour. This pale-coloured sandstone appears to be a suitable stone for the repair of decayed stonework in historic Edinbugh. Edinburgh World Heritage Trust sample no. EWHT 60. Ideally replacement stone should be tested by being built adjacent to existing masonry to test its long term behaviour, but in reality this is only feasible for longer-term research. Tests for comparative durability such as acid immersion, sodium sulphate crystallization, water absorption porosity, saturation coefficient and pore size distribution may be useful. Second hand stone should always be considered for stone repairs, as it has proven and more predictable weathering characteristics, although it can be hard to obtain and costly.
