The Geological Survey of India (GSI) had identified a cement grade limestone deposit in the Walayar reserve forest way back in 1961-62.

The limestone deposit was located in the Pandarethu valley of the Walayar region on the northern side of the Palakkad gap.

Despite its difficult terrain and perilous conditions at the deposit, the Kerala State Industrial Development Corporation (KSIDC) had engaged M/s.

The Malabar Cements Limited thus came into existence at Walayar, the then remote and underdeveloped tiny village in the eastern boundary of the Palakkad District.

Development of the Cherthala plant began in August 2003 as part of an expansion plan by the company that included commissioning a 600 TPD Grinding Unit.
