This product is made of polyethylene (HDPE) plastic base plate that is stamped into conical protrusions or convex points with stiffening ribs (or hollow cylindrical porous) to form a drainage board. It adopts magic knot self-adhesion, convenient and highly constructed, has strong tensile properties, compressive strength and puncture resistance, good hydrophobicity, and is widely used in tunnel drainage projects such as railways, highways, and subways.
YN-A502 Convex shell drainage board
Implementation standard:CR/Q562.3-2018
- Product Features
- High tensile strength, above 13MPa at room temperature; large elongation at break, up to 700% at room temperature; good stress resistance and crack resistance, easy to adapt to water expansion and rupture of structures;
- Good low temperature resistance and bending performance, still has good bending performance below -35℃; can adapt well to changes in ambient temperature;
- The product has excellent flexibility, wear resistance and puncture resistance;
- It is resistant to corrosion by acids, alkalis, salts and other media, and molds. It has stable performance against acids, alkalis and other chemicals in concrete or sand, and is suitable for underground projects such as tunnels and civil engineering.
- Good construction performance: The overlapping parts of the coiled materials can be hot-melt welded to achieve the ideal construction effect
- Scope of application
- Mainly used for tunnel waterproofing projects in railways and subways;
- Engineering waterproofing of highway and railway culverts;
- Waterproofing, anti-seepage and moisture-proofing projects for underground construction projects such as various municipal projects, sewage treatment pools and civil air defense projects;
- Anti-seepage projects for water conservancy projects, dams, drainage ditches and artificial lakes
- Precautions
- The plastic sheet is rolled into a cylindrical shape and packed in a plastic bag or a woven bag;
- When transporting and storing materials, be careful not to damage the packaging and place them in a ventilated and dry place;
- The storage stack height should not exceed the height of five flat sheet rolls. When stacking, it should be placed on a dry level ground, away from direct sunlight, prohibited from contact with acids, alkalis, oils and organic solvents, and isolated from heat sources;
- Prevent tilting or squeezing during transportation, and cover with felt cloth if necessary;
- Under normal transportation and storage conditions, the storage period is 1 year
