Approach method

Whether it's a flat roof or a sloped roof, the materials used for new construction and renovation work are outstanding in terms of cost-effectiveness.

The "Aptorch Method" is a waterproofing technique developed by Towa Kogyo that involves heating and bonding modified asphalt sheets using a torch burner. In the waterproofing industry, various new waterproofing materials and methods have emerged in response to changes in societal conditions. Among these, this method has a proven track record of high reliability associated with asphalt waterproofing, as well as excellent evaluations as an environmentally friendly and labor-saving technique. It is environmentally friendly due to the minimal generation of harmful substances from the melting of asphalt. **Advantages of the Aptorch Method** - One side of the sheet is tapered to a width of 100mm, covering the weaknesses of thick sheet finishes. - The resin film attached to the back of the sheet easily melts under the heat of the torch burner, without hindering adhesion. - The melting state can be visually confirmed. - Complete waterproofing effects, including accessories, can be achieved with carefully prepared auxiliary materials. - It offers excellent cost-effectiveness with common materials for both new construction and renovation, regardless of flat or sloped roofs. *For more details, please refer to the PDF document or feel free to contact us.*
