A delegation from the European Parliament will visit Donegal as part of an investigation into defective concrete blocks.
MEPs from Spain, Estonia and Latvia as well as Ireland also visit Dublin.
The visit follows several petitions and debates by the Committee, highlighting the issue of defective mica blocks used in construction in Ireland.
Midlands-North West MEP Colm Markey, who is part of the delegation, has said the purpose of the trip is to establish the facts surrounding mica and allow homeowners to resume their lives as normal.
