Emile Elias: TCL can fill gap left by Rock Hard cement shortfall A delivery of Rock Hard cement at a hardware in San Fernando in 2017. File photo - One local contractor does not believe the increase in cement prices from one local supplier will have significant negative impacts on the construction sector. NH International executive chairman Emile Elias said the new prices of Rock Hard Distributors Ltd posed no threats to the cement supply and Trinidad Cement Ltd (TCL) can fill the gaps. He told Newsday on Thursday, “There is nothing that Rock Hard cement either does or can do that will impact on the local construction sector. They are a peripheral player and some of the allegations they made against the government are simply not true."
