Balvac repaired this 13th century castle in North Wales, helping to preserve the historic ruin for future generations.
Working with conservation and archaeological specialists, we employed a number of techniques to combat the inclement weather and strong coastal winds weakening the castle’s sandstone walls.
Cracked lintel stones above window openings were pinned following resin injection to prevent further damage and to provide support. We stabilise weak and weathered stones by covering the surface of the walls with a low viscosity sealant. We tied loose masonry in place to prevent falling debris before filling in the joints with mortar and resin, ensuring a longer lifetime for the castle.
