This 100 year old Limestone terrace at Queen’s University was restored in the summer of 2016. Long term moisture ingress and free-thaw cycles had pushed the stone wall apart. When the project was tendered, sections of the wall had already collapsed. Edgewater mobilized to site and documented the remaining walls, photographing and numbering each stone. We also used historical photographs to identify stones that had fallen from the wall. The terrace was completely dismantled and all stones cleaned and stored for reuse. We used local Limestone to replace damaged units, and squared pieces to match the existing material.

The wall was then rebuilt to original measurements and details such as the drainage scuppers were reinstated. The Limestone terrace pavers were stored by Queens and replaced with a pre-cast interlock substitute to ensure adequate drainage.
