Plant root blocking can prevent plant roots from penetrating the waterproof layer and causing the failure of waterproof function; In the absence of plant root blocking measures, the root system of plants planted on the roof will pierce into the waterproof material, causing damage to the waterproof layer, resulting in leakage.

防止植物根穿透結構層而造成更為嚴重的結構破壞；在沒有植物根阻攔措施的情況下，屋面所種植物的根系會扎入屋面突出物（如電梯井、通風孔等）的結構層、女兒墻而造成結構破壞。這種破壞一方面來講不僅比一種情況會增加更多的維修費用，而另一方面這種破壞如不及時補救，將會危及整個建筑物的使用安 全。

Prevent plant roots from penetrating the structural layer and causing more serious structural damage; In the absence of plant root blocking measures, the root system of plants planted on the roof will penetrate into the structural layer and parapet of roof protrusions (such as elevator shaft, ventilation hole, etc.) and cause structural damage. On the one hand, such damage will not only increase the maintenance cost more than one case, but on the other hand, if it is not remedied in time, it will endanger the use safety of the whole building.

避免由于植物根穿透造成防水層破壞甚至結構破壞而帶來的連帶損失；屋面結構層上進行園林建設,由于排水、蓄水、過濾等功能的需要，屋面種植結構層遠比普通自然種植的結構復雜，而防水層一般處于＊下面一層。

Avoid associated losses caused by waterproof layer damage or even structural damage caused by plant root penetration; Garden construction is carried out on the roof structure layer. Due to the needs of drainage, water storage, filtration and other functions, the roof planting structure layer is far more complex than the ordinary natural planting structure, and the waterproof layer is generally located on the lower layer of *.

如果忽略了植物根阻攔層的設置，植物根穿透防水層，將會導致結構層大面積滲漏，必 須進行及時維修，情況嚴重，就必 須更換防水材料，這意味著：必 須將上面已經精心培養成熟的植物層及土層全部鏟除，排水層及過濾層等也要全部鏟除，然后才可能更換已經千瘡百孔的防水層,增加不必要的直接維修費用。同時，維修過程中所需材料、機具的搬運及運輸會影響建筑物的正常運作，建筑物所有者為保持清潔和形象而導致的間接損失不可估量。

If the setting of plant root blocking layer is ignored, plant roots penetrating the waterproof layer will lead to large-area leakage of the structural layer, which must be repaired in time. If the situation is serious, the waterproof material must be replaced, which means that the above carefully cultivated and mature plant layer and soil layer must be eradicated, and the drainage layer and filter layer must also be eradicated, Then it is possible to replace the damaged waterproof layer and increase the unnecessary direct maintenance cost. At the same time, the handling and transportation of materials, machines and tools required in the maintenance process will affect the normal operation of the building, and the indirect losses caused by the building owner to maintain cleanliness and image are immeasurable.

選用適當的植物根阻攔材料,以及植物根阻攔層與整個種植屋面系統的配合是關鍵中的關鍵。

The selection of appropriate plant root blocking materials and the cooperation between plant root blocking layer and the whole planting roof system are the key.

現在有一種SBS改性瀝青制成的卷材，瀝青涂層中含有活性極強的生物阻根添加劑，中間一層銅-聚酯復合胎基賦予產品獨具的植物根阻攔功能，具有植物根阻攔功能、高耐折力和持久的低溫柔度。用作植物根阻攔層的頂層。

Now there is a coiled material made of SBS modified asphalt. The asphalt coating contains highly active biological root blocking additives. The middle layer of copper polyester composite tire base gives the product a unique plant root blocking function, with plant root blocking function, high bending resistance and lasting low-temperature flexibility. Used as the top layer of plant root barrier.
