PEE Composite Drainage & Filtration System - High-Performance Multi-layer Geosynthetic Material
Product Overview
PEE is a premium composite geosynthetic material integrated with a composite filter layer, permeable core components, and functional auxiliary layers. Adopting a scientific three-layer structural design, it achieves the integration of filtration, drainage, and structural support, delivering reliable performance for complex engineering scenarios:
Upper Filter Layer: Precisely intercepts soil particles and impurities to prevent clogging of internal drainage channels, while ensuring unobstructed water penetration—effectively protecting the integrity of the soil structure.
Middle Drainage Layer: Features optimized continuous flow channels that rapidly guide seepage water, accumulated water, or leachate to designated discharge areas, significantly reducing pore water pressure and avoiding structural damage.
Lower Permanent Formwork Layer: Serves as a stable, corrosion-resistant permanent formwork, enhancing the structural stability and safety of engineering facilities (e.g., retaining walls) during construction and long-term service.
Specification Model
The overall composite filter layer of PEE has a width of 0.5m, and its thickness is available in four options: 10mm, 15mm, 20mm, and 30mm
Wide Application Scope
PEE is a versatile solution widely adopted in multiple engineering fields, addressing drainage and structural support needs across scenarios:
Traffic Engineering
Highway & railway subgrades and pavements (preventing water accumulation-induced settlement)
Dams, slope protection systems, and retaining walls (specialized for water diversion and drainage)
Traffic tunnel drainage and culvert water guiding projects
Municipal Engineering
Urban road subgrades and subway tunnel drainage
Landfill groundwater and surface water drainage (compatible with leachate management systems)
Municipal green space and square drainage facilities
Construction Engineering
Building foundation drainage and basement anti-seepage drainage
Retaining wall construction (as integrated drainage + formwork material)
Sports field drainage systems (e.g., football fields, golf courses
Core Product Features
Superior Drainage Performance: Optimized middle drainage layer with high water permeability, ensuring rapid discharge of excess water and long-term unobstructed flow.
Simplified & Safe Construction: Lightweight design with standardized dimensions, enabling quick laying, easy operation, and reliable performance—reducing construction time and labor costs.
Permanent Formwork & Corrosion Resistance: The lower formwork layer acts as a durable, non-corrosive structural support, enhancing the stability and service life of retaining walls and other facilities without secondary maintenance.
Integrated Multi-Function: Combines filtration, drainage, and structural support in one product, eliminating the need for multiple separate materials and lowering overall engineering costs.
