Heavy Metal Adsorption Sheet for Soil Contamination Countermeasures "Padem Sheet"
Making the adsorption layer construction easier. No need for mixing work or quality control of the adsorption layer on site. Slope construction is also easy.
The "Padem Sheet" adsorbs harmful substances (heavy metals) in the soil generated during tunnel excavation and construction work, preventing their outflow. The sheet is evenly filled with adsorbent material, and when laid manually, the adsorption layer is completed. Unlike conventional adsorption layer methods that require mixing soil and adsorbent material on-site or managing the quality of the adsorption layer, it achieves reduced construction work and stable quality. It can be cut and pasted to fit the terrain, making it easy to install even on slopes and complex terrains. The seams of the sheet can be welded together without gaps, providing a high outflow prevention effect. 【Features】 ■ Dimensions: Thickness 2mm × Width 1.5m × Length 20m. Can be efficiently laid over a wide area. ■ No heavy machinery is required during installation. Simply unroll the sheet manually. ■ Adsorbs harmful substances such as arsenic, selenium, lead, cadmium, and fluoride. ■ No concern about uneven distribution of the adsorbent material. *For more details, please refer to the materials.

basic information
The "Padem Sheet" is a jointly developed product by Toppan Printing Co., Ltd. and ES Research Institute, Inc. It is a sheet filled with the adsorbent "Interface SMV#IR," which adsorbs harmful substances such as arsenic and selenium contained in the soil. In the adsorbent layer method that adsorbs and treats heavy metals, it is used as a base layer instead of the adsorbent layer. 【Standard Construction Procedure (when laying one layer)】 1. Ground leveling 2. Installation of protective mat (on the base surface side) 3. Installation of Padem Sheet 4. Installation of protective mat (on the contact surface side with excavated soil) 5. Transportation and leveling of protective soil *For more details, please refer to the materials. Feel free to contact us with any inquiries.
