Since our founding, we have strived to improve our products through continuous research and development to solve the problems of existing waterproofing materials. In particular, the “Self-Lap Sheet” is an asphalt sheet using self-adhesive method, which is mainly preferred in Europe and the Americas. It is safe as it does not require the use of a torch, and is also ecofriendly as it was developed in a low-carbon method. In addition, it is designed to enable simple construction using the patented release film method and requires only a small number of materials. By enabling OEM and ODM, we are striving to grow into a company that adapts to not only the domestic market but also the global market.
