Lagan Brick said it will re-open a factory in Kingscourt in Co Cavan on the site of its old Lagan Brick facility.
The development, which is being supported by Enterprise Ireland, follows improvements in the British and Irish construction sectors.
The factory will be the only producer of bricks on the island. The current demand for 30 million bricks is serviced by imports.
CRH closed down rival Ormonde Bricks in the Kilkenny town of Castlecomer during the bust.
“Today’s announcement by Lagan Brick that it is to create 30 new jobs in Kingscourt is a great boost for Cavan,” said Enterprise Minister Richard Bruton. “Lagan Brick is a great example of the type of Irish manufacturing, engineering and construction companies my Department supports in every region of the country.”
Lagan Brick closed the factory in Kingscourt three years ago as the recession reaches its nadir.
“We have strong links with the site stretching back to 1984 and have invested heavily here in the past,” Lagan general manager Jody Guilfoyle said yesterday.
