Stronghold Preservation, as a specialist damp proofing company, was asked to submit a tender for remedial works during the major renovation of the Custom House, Derry.
Due to the successful tender submission, Stronghold Preservation carried out an
electro osmosis damp proof course,
cementitious tanking and
woodworm treatment on the Custom House.
Further Information
Electro Osmosis DPC
The architect had specified that an electro osmosis damp
proof course be installed, to remedy the rising damp
problem. Electro osmosis was the chosen damp proof course, as
it is generally a more suitable remedial damp proof treatment for
rising damp in solid stone walls. A 20 year guarantee was
issued for the remedial damp proof course.
Cementitious Tanking
Due to the external ground levels being slightly higher than the
internal finished floor in some places, the architect had specified
certain areas to have cementitious
tanking carried out. A 10 year guarantee was issued for
the tanking.
Woodworm Treatment
Also included in the tender was woodworm treatment, carried out to the first
and second floor joists, and the timbers in the roof: all affected
areas were sprayed with an insecticide. A
20 year guarantee was issued for the woodworm treatment.
The Custom House, since its refurbishment, operates as a
restaurant and wine bar. It was built in 1876 and is a Grade
B1 listed building.
