Anti – penetration Geomembrane
Short Description:
The anti – penetration geomembrane is mainly used to prevent sharp objects from penetrating, thus ensuring that its functions such as waterproofing and isolation are not damaged. In many engineering application scenarios, such as landfills, building waterproofing projects, artificial lakes and ponds, there may be various sharp objects, such as metal fragments in the garbage, sharp tools or stones during construction. The anti – penetration geomembrane can effectively resist the penetration threat of these sharp objects.

Material Properties
- Multi - layer Composite Structure: Many anti - penetration geomembranes adopt a multi - layer composite form. For example, the anti - penetration geomembrane with high - density polyethylene (HDPE) as the main material may be compounded with one or more layers of high - strength fiber materials, such as polyester fiber (PET), outside its core waterproof layer. Polyester fiber has a high tensile strength and tear - resistant strength, which can effectively disperse the local pressure exerted by sharp objects and play an anti - penetration role.
- Addition of Special Additives: Adding some special additives to the material formula can enhance the anti - penetration performance of the geomembrane. For example, adding an anti - abrasion agent can improve the abrasion - resistant performance of the geomembrane surface, reduce the surface damage caused by friction, and then enhance its anti - penetration ability. At the same time, some toughening agents may also be added, so that the geomembrane can have better toughness when subjected to a puncture force and is not easy to break.

Structural Design
- Surface Protection Structure: The surface of some anti - penetration geomembranes is designed with a special protection structure. For example, a raised granular or ribbed structure is used. When a sharp object contacts the geomembrane, these structures can change the puncture angle of the object and disperse the concentrated puncture force into component forces in multiple directions, thereby reducing the possibility of puncture. In addition, there is a relatively hard protective layer on the surface of some geomembranes, which can be formed by coating a special polymer material, such as a wear - resistant and high - strength polyurethane coating, which can directly resist the penetration of sharp objects.
Application Scenarios
- Landfill Engineering
- In the waterproof treatment of the bottom and slopes of landfills, the anti - penetration geomembrane is of vital importance. Garbage contains a large number of various sharp objects, such as metal and glass fragments. The anti - penetration geomembrane can prevent these sharp objects from penetrating the geomembrane, avoid the leakage of landfill leachate, and thus protect the surrounding soil and groundwater environment.
- Building Waterproofing Engineering
- It is also widely used in building basement waterproofing, roof waterproofing, etc. During building construction, there may be situations such as tools falling and sharp corners of building materials. The anti - penetration geomembrane can ensure the integrity of the waterproof layer and extend the service life of the building waterproofing system.
- Water Conservancy Engineering
- For example, in the construction of water conservancy facilities such as artificial lakes and landscape ponds, the anti - penetration geomembrane can prevent the bottom of the lake or pool from being pierced by sharp objects such as stones and roots of aquatic plants. At the same time, in the anti - seepage project of some water - conservancy irrigation channels, it can also prevent the bottom and slopes of the channels from being damaged by sharp objects such as irrigation equipment and farm tools.
