Application

1. Water conservancy and coastal engineering: saline-alkali land slope protection, used for dam protection in salinized areas, strong corrosion resistance.

2. Highway and railway projects: Soft foundation isolation, laid on soft soil foundation, separates soil layers and enhances bearing capacity. Pavement anti-reflective cracks.

3. Environmental protection and anti-seepage projects: chemical park anti-seepage, landfill isolation

4. Agriculture and gardening: drainage ditch filtering, salt field anti-seepage

5. Temporary projects: reinforcement of construction access roads

6. Mining and stockyards: slag stockyard isolation, tailings pond anti-seepage base

Features

1. High strength and tear resistance: high longitudinal tensile strength (depending on weight) and strong puncture resistance.

2. Chemical corrosion resistance: Polypropylene material has excellent acid and alkali resistance and is suitable for chemical pollution areas, saline-alkali land or seawater environments.

3. Water permeable and impermeable to soil: The pore structure allows water to penetrate freely, while effectively preventing the loss of soil particles and maintaining soil stability.

4. Lightweight and economical: low density, low transportation and construction costs, and overall cost performance better than traditional sand and gravel isolation layers.

5. Convenient construction: it can be cut, sewn or hot-melt connected to adapt to complex terrain and be laid quickly.
