Conservation of a Grade II listed chapel in Pembrokeshire

This medieval chapel sits in the middle of the Castlemartin Royal Armoured Corps firing range.  Redundant by the early 19^thC, it was converted latterly to form a cart house for the adjoining farm.  It was restored and rededicated by Col. Francis and Lady Victoria Lambton in 1901-3.  Restoration works were extensive and included the erection of a new S. porch.  The stone vaulted roof was reslated in what is believed to be Delabole slate ,graded and solid bedded on a sand/cement bed.  Later repairs had included extensive sand/cement repointing further exacerbating damp ingress.

Over the last 2 years, during a 4 week window in August of each year, Acanthus Holden architects have designed and managed a scheme for the re-roofing and repointing of the chapel with associated repairs.  The re-roofing was carried out using Argentine Riverstone slates with diminishing courses.  To reduce damp tracking, the slates were nailed to battens and tail bedded in a lime mortar.

Phase II masonry involved the repointing of the entire chapel using an N.H.L 3.5 mix.  The exposed W. wall was shelter coated in N.H.L 3.
