"O-PHALT" is a one-component modified asphalt waterproofing material of emulsion type, primarily made from rubber and asphalt. It forms a seamless waterproof layer without selecting the shape of the substrate. Additionally, it does not contain substances subject to the Industrial Safety and Health Act or the Specific Chemical Substances Hazard Prevention Regulations, such as formaldehyde and other environmental hormone-related substances, allowing for safe application in various locations, both indoors and outdoors. 【Features】 ■ Environmentally friendly waterproofing material not subject to specific regulations ■ Safe and secure application without the use of fire or solvents ■ Forms a seamless waterproof layer with asphalt-based waterproofing material ■ F☆☆☆☆ certification obtained ■ No mixing process required, ensuring stable quality *For more details, please refer to the PDF document or feel free to contact us.

"OS-sheets" are environmentally friendly, economically effective, and feature excellent durability of modified asphalt and watertight joints, while also possessing compatibility with the substrate and breathability as a waterproof single-layer sheet. By shortening the process, it leads to reduced construction time and costs. At the time of sheet installation, the self-adhesive seal at the joint blocks the intrusion of rainwater! You can rest assured even during sudden rain. Furthermore, only the sheet joint area is heated, allowing for large-scale installation using just a hand torch burner. Additionally, we offer a one-component modified asphalt-based coating waterproofing material called "O-PHALT." 【Features】 ■ Sandwich structure of modified asphalt layer ■ Minimizes the use of open flames ■ Safe design that seals during sheet installation ■ Equipped with temporary waterproofing function *For more details, please refer to the PDF document or feel free to contact us.

"O-PHALT BASE" is a temporary waterproofing material suitable for interim waterproofing from the removal of the existing waterproof layer to the installation of new waterproof materials in waterproof renovation work. Since "O-PHALT BASE" is asphalt-based, it exhibits excellent compatibility and adhesion with other asphalt-based waterproof materials. It can also be used as a substrate adjustment material after the removal of the existing waterproof layer. It can be used even when the substrate is damp, and due to its excellent adhesion to concrete and mortar, it can be applied immediately after the removal of the existing waterproof layer. Its quick-drying properties contribute to shortening the construction period and prevent rainwater intrusion during the work until the new waterproof material is installed. 【Features】 ■ Particularly excellent adhesion to concrete, mortar, and asphalt-based waterproof layers ■ Water-based emulsion type, allowing application to damp substrates ■ Excellent quick-drying properties enable immediate subsequent work, thus shortening the construction period ■ Uses environmentally friendly materials that do not contain environmental hormone formaldehyde ■ Can be used as a temporary waterproofing material, substrate adjustment material, and even as a main waterproofing material simply by changing the mixing ratio *For more details, please refer to the PDF document or feel free to contact us.
