Water damage is preventable — but only if addressed at the right stage. Moisture infiltrates concrete, corrodes reinforcement, and degrades structures silently, long before visible signs appear. We work with developers, contractors, architects, engineers, and property owners to specify and apply the best waterproofing system for every project — new construction, renovation, or repair. Every solution starts with a proper assessment, book a free technical assistance today.
E-Hsing Corporation was founded in 2002 with a straightforward purpose: to bring quality building materials to the Philippine market. Over the next two decades, the company would go through two significant pivots — each one a deliberate move toward deeper specialisation and greater value for the clients we serve. Today, we are the only manufacturer and exclusive distributor of CASTLE® Waterproofing products in the Philippines, and the exclusive distributor of LARSEN® PLASTER-WELD — two products that have defined their respective categories in Philippine construction.
~ Year 2002 ~
E-Hsing Corporation enters the Philippine building materials industry through the sales and distribution of Homogeneous Granite Tiles under the SunPower brand. The foundation is laid: a commitment to quality materials and reliable supply.
~ Year 2006 ~
Recognising the growing demand for specialised waterproofing solutions, E-Hsing pivots decisively. We become the exclusive distributor of CASTLE® Waterproofing in the Philippines — a product backed by decades of manufacturing expertise and built on Japanese integrated technology. This marks the beginning of our identity as a waterproofing company.
~ Year 2014 ~
E-Hsing takes on the exclusive distribution of LARSEN® PLASTER-WELD in the Philippines — a concrete bonding agent patented in 1952 and credited with creating the bonding agent category in the global construction industry. A natural complement to our waterproofing offering, and one we continue to distribute to this day.
After 18 years as exclusive distributor — building technical expertise, deepening market knowledge, and earning the trust of the Philippine construction industry — E-Hsing acquires full manufacturing rights for CASTLE® Waterproofing. We are now the sole manufacturer and distributor of CASTLE® Waterproofing in the Philippines, with a local technical team that supports every project from assessment to completion.
