Hongyue composite waterproof and drainage board
Short Description:
Composite waterproof and drainage plate adopts a special craft plastic plate extrusion enclosed barrel shell protrusions formed concave convex shell membrane, continuous, with three dimensional space and certain supporting height can withstand a long high, can not generate deformation. The top of the shell covering geotextile filtering layer, to ensure that the drainage channel does not block due to external objects, such as particles or concrete backfill.
Products Description
The composite waterproof and drainage board is composed of one or two layers of non-woven geotextile and a layer of three-dimensional synthetic geonet core. It has the comprehensive performance of "reverse filtration-drainage-breathability-protection". This structure makes the composite waterproof and drainage board perform well in various projects, especially in drainage projects such as railways, highways, tunnels, municipal projects, reservoirs, and slope protection.
Application Scenarios
Composite waterproof and drainage boards are widely used in a variety of engineering fields:
1. Railways, highways, tunnels, municipal projects: used for drainage and protection.
2. Reservoir and slope protection: used for reinforcement and protection.
3. Soft foundation treatment, roadbed reinforcement, and slope protection: improve stability and drainage effect.
4. Bridge abutment reinforcement, coastal slope protection: prevent erosion and protect structures.
5. Underground garage roof planting and roof planting: used for waterproofing and drainage, protecting the structure.
Performance Characteristics
1. Strong drainage: equivalent to the drainage effect of one meter thick gravel drainage.
2. High tensile strength: able to withstand high pressure load, such as 3000Ka compression load.
3. Corrosion resistance, acid and alkali resistance: long service life.
4. Convenient construction: shorten the construction period and reduce costs.
5. Good flexibility: capable of bending construction and adapting to various complex terrains.
