In landscape engineering projects, the application of HDPE membrane and GCL bentonite waterproof blanket is booming, especially in recent years, the awareness of garden landscape has been strengthened, and the long-term utilization of landscape has been demanded. HDPE impermeable membrane and GCL bentonite waterproof blanket are being accepted and used by many people. In particular, GCL bentonite waterproof blanket is praised as "breathing anti-seepage material" in the industry, and is especially suitable for garden landscape water system projects with high ecological environment requirements. In the anti-seepage treatment project of garden landscape, HDPE anti-seepage membrane or GCL bentonite waterproof blanket has obvious anti-seepage effect, durability and flexibility compared with traditional soil-mud concrete, stone stacking, anti-seepage of paint, etc. Is A new product with good permeability, convenient construction and easy maintenance. Cement concrete has a long construction period and high cost, while HDPE anti-seepage membrane and GCL bentonite waterproof blanket have short construction period, simple construction, convenient maintenance, low investment cost, good anti-seepage effect, which can meet the design requirements of garden landscape and environmental protection policies. Therefore, with the rapid development of the domestic economy today, under the demand of the continuously growing garden landscape market, the anti-seepage application of HDPE geomembrane in landscape engineering has also been greatly increased.
