GRASS-PROOFING SHEET

摘要

PROBLEM TO BE SOLVED: To provide a grass-proofing sheet capable of suppressing growth of weeds. SOLUTION: This grass-proofing sheet can be made by putting into a solidification material bag. It is preferable to use pressurized fluid bed coal ash and blast furnace slag fine powder for a solidification material. The bag has preferably a synthetic fiber cloth such as polyester and a biodegradable material. The solidification material in the bag is evenly arranged by dividing the inside of the bag into more than 2 spaces and arranging the solidification material in each the divided space. A method which comprises laying the grass-proofing sheet on a place requiring suppression of growth of weeds and solidifying the solidification material by water can suppress growth of weeds on a target place.
