CRH confirmed in 2013 that it was interested in looking at other opportunities in India. In 2015, CRH remained listed in both London and Dublin. In February 2015, CRH agreed to purchase the UK building materials producer Lafarge Tarmac. In 2015, CRH purchased US$6.5 billion of assets from the newly formed company LafargeHolcim. The acquisition almost tripled CRH's net debt, bringing it to €6.6 billion. The LafargeHolcim acquisition made CRH "the world’s third-largest building materials group by market value." A week after CEO Albert Manifold announced that CRH was looking for large-scale acquisitions, in August 2015, CRH paid $1.3 billion for CR Laurence, a glazing company based in California. At the time, CRH already had a similar business in North America called BuildingEnvelope, with 4,500 employees, which it said it would integrate with CRH. By November 2015, CRH was getting about a fifth of its operating earnings from US infrastructure.
