A waterproof sheet with excellent substrate adhesion and a wide temperature application range.
The "Kurtal Civil Engineering Sheet" is a waterproof sheet that has been practically developed as a civil engineering waterproofing material using a modified asphalt cold adhesive method. The important lap joints in civil engineering waterproofing are prevented from adhesive failure due to the excellent properties of the Kurtal sheet, such as viscoelasticity, self-healing, and a three-layer structure centered around a core material, which allows for viscous deformation and ensures integrated watertight adhesion. It has been adopted in many waterproofing projects, including the Tokyo Metropolitan Subway, Yokohama Subway, and Haneda Airport, and has been widely used as a "trusted material" for over 40 years. 【Features】 ■ Lap joints integrate to form watertight adhesion ■ Excellent substrate followability ■ Wide applicable temperature range ■ Forms a highly reliable waterproof layer *For more details, please download the PDF or feel free to contact us.

Company information
Towa Industries was established in 1953 with the aim of manufacturing asphalt-based corrosion protection materials for electrical cables, as well as waterproofing, dew prevention, and thermal insulation asphalt roofing and tapes. Since then, we have advanced research and development and improvements with our unique technology, producing modified asphalt roofing materials for waterproofing applications in construction, civil engineering, and bridges. Utilizing research results on the waterproofing, anti-corrosive, thermoplastic, electrical insulation, and shock-absorbing properties of asphalt, we manufacture sealing materials for waterproofing around oil tank bases and joints in embankments, as well as injection joint materials for roads. Additionally, we leverage our production facilities for processing such as mixing, kneading, punching, and cutting, and we offer a wide range of contract manufacturing services. If you are looking for outsourcing for kneading processes, extrusion molding processes, or prototypes, please feel free to consult with Towa Industries. We also accept various packaging and light work tasks. Our factory in Itabashi, Tokyo, can handle small lot orders and provides prompt responses. Please do not hesitate to reach out with your requests.
