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 30m bricks per year 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," Enterprise Minister Richard Bruton said yesterday. "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.
"Current buoyancy in the construction market here and in the UK, indicates that there is strong demand for the quality product we can deliver. Our management experience and knowledge of the sector allied to our strong Lagan brand are key ingredients for a bright future," Mr Guilfoyle added.
The company will commission one kiln in the first phase of its new operation, producing 12m bricks a year however; the long term aim of the business is to have two kilns fully operational with a further eight million bricks potentially being produced.
UK demand for bricks is likely to be in the region of 2.2 billion bricks. Lagan said yesterday that it already has a footprint in the UK and sees this extra capacity as a real export opportunity.
Twenty of the jobs will be created immediately, the ten remaining positions to be phased in when the second kiln is in operation.
"It is estimated that a further 10 to 20 spin-off jobs will be created and sustained immediately in the area as a result of the investment," Lagan said yesterday.
Lagan added that it expects to have recruitment completed within the next month with brick manufacturing expected to begin in the new facility over the summer.
