What types of waterproofing are there?

Speed up! Cost down! Two processes reduced to one.

Introducing the modified asphalt waterproof sheet "OS-sheets" handled by Robusto. There are various types of waterproofing, including the "coating method," which can accommodate complex shapes, the "sheet method," which creates a uniform thickness of the waterproof layer, and the "coating + sheet method," which produces a thick waterproof layer with high waterproofing properties. Traditionally, two processes were required: a ventilation layer and a waterproof layer to allow moisture to escape. With "OS-sheets," it is possible to consolidate these processes. Two processes are reduced to one. 【Types of Waterproofing】 ■ Coating method (membrane waterproofing) ■ Sheet method (sheet waterproofing) ■ Coating + sheet method (asphalt waterproofing thermal method) *For more details, please refer to the PDF materials or feel free to contact us.

Features of OS-sheets

Features of OS-sheets

The conventional layering process has been shortened to one step! Sandwich structure of modified asphalt layer.

"OS-sheets" are single-layer sheets that enable the functions of the traditional two-layer system: a "bottom" ventilation layer and a "top" waterproof layer. As a result, the conventional lamination process has been shortened to one step, allowing for a reduced construction period. 【Features】 ■ Sand granules: Protect the waterproof layer and prevent UV degradation ■ Modified asphalt: Asphalt with additives such as rubber and plastic ■ Synthetic fiber non-woven fabric: Improves dimensional stability and tensile strength ■ Partially adhesive self-adhesive layer: Maintains breathability while also excelling in insulation *For more details, please refer to the PDF document or feel free to contact us.

OS-sheets Ventilation System with Continuous Air Release Path from the Ventilation Layer

OS-sheets Ventilation System with Continuous Air Release Path from the Ventilation Layer

Achieving labor-saving and productivity improvement in construction! Environmentally friendly waterproofing construction system *Patent obtained! Patent No. 7001280

The "OS-sheets Deaeration System" is a deaeration tube that ensures a continuous deaeration path from the ventilation layer. It has been developed as a deaeration tube that further enhances the benefits of OS-sheets. *Patent obtained! Patent No. 7001280 ★What are OS-sheets? "OS-sheets" are single-layer sheets that have two essential functions (breathability and waterproofing) for waterproof sheets. They are single-layer modified asphalt waterproof sheets that conform to JIS A 6013, possessing the same functions as two-layer sheets while allowing for reductions in materials, processes, and labor, as well as shortening construction periods. *For more details, please refer to the PDF materials or feel free to contact us. *The effectiveness is demonstrated when used with "OS-sheets"! For more information, please check below: 【【Addressing Labor Shortages】10-Year Warranty (extendable) Modified Asphalt Waterproof Sheet 'OS-sheets'】.

Modified asphalt waterproof sheet "OS-sheets"

Modified asphalt waterproof sheet "OS-sheets"

Stop rainwater with the self-adhesive seal part! Waterproof sheet with joint watertightness.

"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.

[Road Bridge Deck Waterproofing Method] Room Temperature Adhesive Type Deck Sheet J (Civil Engineering / Bridge)

[Road Bridge Deck Waterproofing Method] Room Temperature Adhesive Type Deck Sheet J (Civil Engineering / Bridge)

It has good workability and can accommodate short construction periods! This is a cold adhesive modified asphalt sheet that integrates through compaction and the residual heat of paving.

"Floor Plate Sheet J" is a cold adhesive waterproof sheet for bridge floor plates, coated with modified asphalt on a glass substrate that boasts high durability and excellent dimensional stability. It meets the quality standards of the basic verification tests in the Road Bridge Floor Plate Waterproofing Manual and integrates through melting due to rolling and the residual heat from paving, considering safety and the environment. The cold adhesive type can reduce CO2 emissions during construction and is characterized by relatively few occurrences of blistering (such as bulging) after waterproofing, making it suitable for areas with thin pavement thickness, such as sidewalks, and less affected by site constraints. 【Features】 ■ Cold adhesive type that integrates through melting due to rolling and residual heat from paving ■ Excellent temperature characteristics, usable over a wide temperature range ■ Superior workability without the need for special construction machinery ■ Excellent followability due to the combination of a robust substrate and high-quality modified asphalt *For more details, please refer to the PDF document or feel free to contact us.
