HDPE V-Lock Anchor Sheet
Permanent Anti-Corrosion Concrete Liner
HDPE V-Lock Anchor Sheet - Permanent Anti-Corrosion Concrete Liner for Wastewater & Tunnel Projects
WhatsApp/Phone: +8613127104111
HDPE V-Lock Anchor Sheet, also known as multi-point anchor plate, concrete protective liner, is integrally extruded from virgin HDPE resin with dense V-shaped anchor studs on the reverse side. Pre-fixed on formwork before concrete pouring, the embedded anchor keys form rigid mechanical interlock with concrete matrix, realizing permanent integration without delamination, peeling or sliding. It combines impermeability, anti-corrosion and crack-bridging functions, widely adopted in wastewater tanks, chemical containment, subway tunnels, landfills and underground pipe galleries all over the world.
Core Product Features
Manufactured with carbon black UV stabilizers and high-efficiency antioxidants, our HDPE anchor sheet meets global geosynthetic anti-corrosion standards, with outstanding comprehensive advantages:
- Permanent Mechanical Anchoring, No Detachment Uniform V-shaped anchor studs are fully wrapped by fresh concrete, forming a monolithic bonded structure. The pull-out resistance exceeds 1.5MPa, effectively resisting thermal expansion, groundwater pressure and structural deformation, completely solving the peeling problem of paint, epoxy coating and adhesive liners.
- Full-Range Chemical Inertness & Anti-Corrosion Resistant to acid, alkali, salt, landfill leachate, industrial wastewater and seawater within pH 2–12. No swelling, aging or degradation under long-term harsh chemical immersion, effectively preventing steel bar corrosion and concrete spalling.
- High Mechanical Toughness & Crack Bridging Performance Tensile strength ≥24kN/m, elongation at break ≥400%. It can absorb structural stress and bridge micro cracks caused by settlement, temperature change and concrete shrinkage, maintaining complete impermeable barrier for long-term service.
- Seamless Hot Welding Zero-Leakage System Smooth front surface supports hot wedge double-track welding, forming continuous integral lining without leakage joints. One layer realizes both anti-seepage and anti-corrosion, simplifying multi-layer construction systems.
- Lightweight & Cost-Effective Construction Low density HDPE material, only 1/7 weight of steel anchor plate, easy to cut, transport and fix on formwork. Replace traditional anti-corrosion coating, FRP lining and secondary waterproof layers, cutting construction period and later maintenance cost by over 30%.
- Non-Toxic & Long Service Life 100% recyclable virgin HDPE without heavy metals. UV stabilized black grade has service life over 50 years for outdoor exposed projects; underground enclosed projects can last more than 70 years.
Standard Specifications

19/25 | 2.0–3.0 | 2/2.5 | 10/15 | ≥36 | Chemical acid-base tanks, landfill concrete base, heap leach mining pads, tailing ponds |
Key Technical IndicatorsCBR puncture resistance ≥450N; Carbon black content ≥2%; Low temperature bending test (-40℃) no crack; Water absorption ≤0.01%.
Wide Application Fields
1. Municipal Wastewater & Sewage Engineering
Sedimentation tanks, anaerobic digesters, sludge storage pools, pumping station concrete walls, drainage culverts. Block corrosive sewage from eroding steel reinforcement, avoid concrete cracking caused by rust expansion.
2. Environmental Solid Waste & Mining Projects
Municipal landfill concrete foundation, leachate regulation tank lining, heap leach pads, tailing pond concrete walls, hazardous waste storage pits. Long-term anti-erosion against heavy metal and acidic leachate.
3. Tunnel & Underground Traffic Engineering
Subway shield tunnel secondary lining, underground comprehensive pipe gallery, tunnel inner anti-corrosion layer. Anchor studs lock tightly with cast-in-place concrete to resist separation under high groundwater pressure.
4. Chemical & Industrial Containment
Acid-base reaction tanks, chemical wastewater lagoons, oil separation pools, factory corrosive trenches. Longer service life and lower maintenance cost compared with FRP and epoxy coating.
5. Water Conservancy & Aquaculture Works
Drinking water reservoirs, irrigation channel lining, fish/shrimp breeding tanks, seawater desalination sediment pools. Non-toxic formula complies with potable water contact standards.
Product Classification
Two mainstream anchor structures for different engineering loads:
- V-Lock Anchor Sheet (Standard Type) Tapered V-shaped studs, balanced anchoring force and cost, the most widely used model for all conventional anti-corrosion lining projects.
- T-Grip Anchor Sheet (High Pull-Out Type) Wide-head T-shaped anchors, superior anti-pull performance, specially selected for deep burial landfills, heavy chemical tanks and high-load vertical walls.
Construction Guidelines
- Mount the smooth flat side against formwork, anchor studs face concrete pouring side to ensure full embedding.
- Overlap adjacent sheets ≥10cm, adopt hot wedge double weld seam for complete impermeability; conduct vacuum leak test after welding.
- Avoid sharp steel bars and coarse aggregate direct impact during pouring to prevent sheet puncture damage.
- Vertical slope installation needs temporary fasteners to prevent sliding before concrete solidification.
- Outdoor exposed lining must choose UV-stabilized black HDPE; light-colored non-UV grades only for fully underground enclosed structures.
International Compliance Standards
- Domestic Standards: GB/T 17643, CJ/T 234-2006
