Founded in March 1966, MARIWASA is one of the pioneers in the Philippine ceramic tile industry. Established by the brothers Emerson and Edison Co Seteng, the company was founded on a vision of producing ceramic products that would meet world standards for beauty and durability. This vision was to be achieved by harnessing the skills, discipline and creativity of the Filipino artisan.

With the technical assistance of leading Italian firms, MARIWASA set up its manufacturing plant along Ortigas Avenue. A series of expansions through the years quickly brought the company to market leadership. The latest addition to the group is a manufacturing facility located in Sto. Tomas, Batangas that showcases the country’s most advanced ceramic tile technology.

MARIWASA holds the distinction of being the first to manufacture both wall and floor tiles in a vast range of colors and sizes. With each MARIWASA tile comes a firm commitment to product excellence that is fully supported by extensive research and development, innovative design and some of the most modern production facilities and processes in the Philippines, all of which are now operating under ISO 9001:2000 and PNS/ISO 13006 quality standards.

Three decades after, Mariwasa Siam Ceramics (MSC) was born after a joint venture of Mariwasa Manufacturing, Inc. (MMI) and a giant Thai conglomerate, Siam Cement Group (SCG). The association with one of Asia’s most admired and ethical corporation generated a new sense of pride and commitment.

In addition to its ceramic tile production, MSC imports sanitary wares and bathroom fixtures to complement its product lines. Product distribution is done through the company’s network of dealers that are positioned strategically throughout the Philippines. Finished products are also exported to Thailand, Singapore, Korea, Saipan, Guam, Palau, Canada, and Africa.
The MARIWASA story is a continuing testimony to Filipino craftsmanship and ingenuity. In each MARIWASA tile is reflected the founders’ vision of excellence – the ability to stand proudly among the world’s finest products.
