Holcim (Lanka) Ltd will invest LKR3.6bn (US$32.8m) in the next three years to strengthen its domestic operations.
Holcim Chairman Manilal Fernando said this will be mainly to increase their grinding capacity in the factory, as well as expansion of their integrated cement plants in Puttalam and also in Trincomalee and Galle.
Fernando also spelled out plans of increasing research in a bid to introduce other raw material for cement manufacture.
"We are also looking at another plant in Sri Lanka," he said.
He said the company sells 1.32Mta of cement adding that with the ending of the war, the construction industry is booming and the present supply of cement is inadequate to meet the demand.
