INSEE Cement

INSEE Cement Sri Lanka is the country’s leading and only fully integrated cement manufacturer offering a comprehensive portfolio of construction solutions to meet the escalating demands of Sri Lanka’s construction landscape.

As an industry pioneer that has shaped Sri Lanka’s skyline over the years, INSEE Cement Sri Lanka continues to steer the local building and construction industry towards high-performing, low-carbon and future-ready constructions, introducing consistently high-quality blended cement products and sustainable building material through the company’s strong investment in innovation and R&D. INSEE Cement Sri Lanka is powered by a strong team of approximately 600 employees spread across a growing local ecosystem; this includes key manufacturing facilities in Puttalam and Galle, a cement terminal in Colombo, a ready-mix batching plant, warehouses, logistics centres, an island-wide dealer network and an industry-transforming innovation and collaboration space to keep Sri Lanka abreast with global industry advancements.

INSEE Cement Sri Lanka, also known as Siam City Cement (Lanka) Limited, is a subsidiary of the Siam City Cement Public Company Limited (SCCC) of Thailand. Drawing from SCCC’s 50-year legacy of operational excellence, industry expertise and accumulated knowledge, INSEE Cement Sri Lanka continues to evolve our long-established, award-winning homegrown brands such as INSEE SANSTHA and INSEE MAHAWELI MARINE into improved, more ecofriendly and high-performance products that can meet the rapid pace of development and urbanisation across Sri Lanka. The INSEE i2i Collaboration Space – our dedicated centre of excellence for new product and idea development, promotes innovation and collaboration across the industry.

We remain committed to our responsibilities towards the environment through continuous carbon emissions reduction across all products and processes. INSEE SANSTHA was the first ecofriendly cement product to receive the Green Labelling Certification from the Green Building Council of Sri Lanka. We continued our efforts and introduced specialized, superior blended cement products powered by years of research and INSEE’s trademarked technologies that add long-term value and mitigate environmental impact, allowing local constructions to drastically reduce their carbon footprint with improved physical and mechanical properties. Our facilities undergo steady improvements in energy efficiencies and utilise alternative fuels and raw material generated by INSEE Ecocycle Lanka (Private) Limited, our industrial waste management solutions arm, playing our part in promoting a circular economy across industrial ecosystems in Sri Lanka. CONWOOD by INSEE is yet another innovative wood replacement material produced by INSEE to further our commitment to sustainable construction.

Alongside our own evolution, we invest in the advancement of all industry stakeholders, from homebuilders to infrastructure developers, from civil engineers to masons, empowering individuals and groups to join and support us in our ambitious vision to elevate Sri Lanka’s building and construction industry to global industry benchmarks.
