When the number of paved construction square meters increases, it can be considered as one of the reservoirs, and the land can be used effectively.
鐵鋼スラグ、高炉スラグ、シラスバルーン、軽石、砕石で透水性、断熱性、保水性の防草ガード舗装は溜枡と同じ効果がある。水の貯溜効果で、ヒートアイランドの抑制ができる。
防草ガード舗装は、環境に優しい２１世紀の環境優しい、省資源・省エネルギー材として活用として成る材料開発と施工、成型加工、工法が特徴です。Steel slag, blast furnace slag, shirasu balloon, pumice stone, crushed stone, water permeable, heat insulating, water retaining weed guard paving has the same effect as basin. The heat island effect can be suppressed by the water storage effect.
The grass protection guard pavement is characterized by material development, construction, molding, and construction methods that are used as environmentally friendly, resource-saving and energy-saving materials in the 21st century.
