He soon gained recognition as a highly reliable and sought-after building contractor and was awarded to build numerous factory for multi-national companies like Western Digital, Flextronics, and Nestle Distribution Centre. By virtue of being a preferred factory and warehouse contractor, his reputation in this arena began to grow and was inevitably asked to construct flooring that commensurate with his quality building works, concrete floors which require better flatness and levelness for high racking. In 1998, he began his foray into the super flat flooring industry and he decided to focus and specialize in the construction of concrete flooring that are conspicuously better, more professional than the ordinary floors in Malaysia.
