Further Information


Woodworm Treatment
The woodworm infestation was quite significant, though confined mainly to the bell tower, and led to floorboards becoming structurally unsound. All the accessible timbers to the bell tower were pressure sprayed with insecticide fluid to eradicate the woodworm.

Newlath Damp Proof Membrane
 The Church was found to be suffering from penetrating damp, limited to the rear of the main Church. The conservation architect proposed that a Newton Newlath damp proof membrane be installed to the damp affected areas. 

Structural Repairs (Cintec Anchors) 
The structural engineer requested that, due to cracking in the bell tower, 4no. Cintec anchors be diamond drilled and installed.

Some of the stone columns had also suffered cracking; Cintec stitching anchors were not suitable, due to the limited cross-section of the columns, and drilling them could have caused them to splinter and split.  Stronghold Prevervation injected resin under pressure into the column, using a resin injection pump.

Stronghold Preservation are approved installers of Cintec anchors & Newton Newlath damp proof membrane.

Holy Trinity Church, Cookstown dates from 1860, was built in the Gothic Revival style from sandstone, and is a Grade B+ listed building, with many of the original internal ornamentation and features retained. The Northern Ireland Environmental Agency describe it as '.... a building of considerable local interest and social value, as well as formal architectural impressiveness.'
