Cured in Place Pipe (CIPP) has been used to rehabilitate twin 1,350 mm diameter culverts crossing the Ballyogan Stream that were at risk of structural failure at the Ballyogan Landfill Site, just outside of Dublin, Ireland. The twin culverts, which extend through the body of the 62 hectare landfill site, convey the Ballyogan Stream through the landfill.
