Deansgrange Library

Dun Laoghaire Area Meeting


To ask the Chief Executive how many repairs have taken place to the leaking roof of Deansgrange Library and to give a cost for each repair?”
Deansgrange Library opened in 1982. The roof at Deansgrange Library is the original, constructed using asphalt tiles and containing original Strammit self-support material (which is compressed straw with metal reinforcement which goes under felt). Rain ingress over the years has damaged the structural integrity of this material, making it soft, and unsupportive, further causing the asphalt tiles to pull and exacerbate water ingress, being original to the roof and becoming less well jointed
over the years. As the strammit has become soft over the years, it has lost its structural integrity and began to retain water.

In 2012, Deansgrange Library refurbishment project concentrated on an extension to the building, with new bay windows and foyer, external surrounding landscaping works including concrete planters, work on addition of toilets, meeting room, also finishes including new flooring, shelving, etc. Other than foyer roof, the roof has not been altered or upgraded since the library was first built. Some minor repairs were
done to the roof over the years but they were temporary patch jobs as follows.

In 2015 the water tank sank into the roof. Repairs to this were made in 2015 and this is when the damage to the supporting strammit system was first revealed. 2015 Roof Repairs cost €1,660 including repairs to water tank and section around this.

My Open Library service was launched in Nov 2018, but the Library had to close for Christmas 2018 due to leaks for unscheduled closure. Latent defects and failed junctions were discovered.

2021 – Current works being tendered to address the problems of both structural support (steel struts) to reinforce internally, (replacing the Strammit which is to be stripped out), plus a new low-maintenance surface covering which will be added to protect the asphalt tiles.
