Feature<\/h3>\n\n\n\n
\n
\n
\n

Long-term durability<\/h4>\n\n\n\n

Modified asphalt with protective sand adhered to the sheet surface provides long-term durability of approximately 20 years.<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n

\n
\n

Workability<\/h4>\n\n\n\n

Weeds can also be prevented from growing from the overlapping parts of the sheets by thermally welding the sheets together.<\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n\n\n\n

\n

Weed prevention performance<\/h4>\n\n\n\n

The structure of PET nonwoven fabric and modified asphalt maintains high penetration resistance and prevents the growth of strong weeds.<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n

\n
\n

Joint with existing concrete surface<\/h4>\n\n\n\n

Compared to conventional weed prevention sheets, this sheet can be joined to asphalt and concrete surfaces, preventing weeds from growing from the edges.<\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n

Construction Procedure<\/h3>\n\n\n\n
\n

Lay the sheet<\/h4>\n\n\n\n

Weed and clear the construction area to make it as flat as possible. Lay the sheet and secure it with anchor pins.<\/p>\n\n\n\n

Single-sided joint type<\/h4>\n\n\n\n

When joining sheets together widthwise, use a single-sided joining type, peel off the release paper on one side, affix the sheet edges, and apply rolling pressure. If necessary, heat welding is performed using a burner.<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n

Full protective sand type<\/h4>\n\n\n\n

When sheets are not connected to each other in width, use the full surface protective sand type.
When making wide joints, use protective sand type on all edges.<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n
