HDPE waterproofing membrane 1.5mm

Overview of HDPE waterproofing membrane 1.5mm

Definition and characteristics of HDPE waterproofing membrane

HDPE (High Density Polyethylene) waterproofing membrane is a non-reinforced geosynthetic material with high durability and absolute waterproofing when properly welded.

• The main material is virgin HDPE resin, enhanced with carbon black (UV resistant) and thermal stabilizers.
• Key properties: high tensile strength, low elongation, chemical resistance, thermal stability, impermeability, and strong impact resistance.
• In construction, HDPE waterproofing membrane acts as a separation and sealing layer for foundations, basements, and technical tanks.

Role of HDPE membrane in civil and industrial structures

• In civil and industrial works, especially foundations, basements, underground tanks, and technical pits, HDPE membranes prevent groundwater infiltration and leakage from soil, ensuring concrete durability.
• Compared with bitumen, PVC, or EVA membranes, HDPE is more flexible, tear-resistant under ground movement, easier to weld, and less intrusive to concrete structure.
• HDPE waterproofing membrane 1.5 mm is thick enough to withstand high hydrostatic pressure, minimize installation risks, and meet requirements for high-grade and industrial projects.

Reasons to choose 1.5mm thickness for concrete waterproofing structures

• Safety threshold: The HDPE waterproofing membrane 1.5mm ensures welded joints can handle water pressure with minimal puncture risk.
• Flexibility & adaptability: When minor ground shifts occur, the 1.5mm HDPE membrane resists tearing better than thinner (<1mm) sheets.
• Cost-efficiency: Compared to 2mm HDPE, 1.5mm thickness offers optimal cost per m² while maintaining technical performance.
• Longevity: The 1.5mm HDPE membrane reduces weak points and extends the waterproofing system’s lifespan.

Technical standards and quality certification of Visco HDPE

Production specifications meeting ASTM and TCVN standards

Visco’s HDPE waterproofing membrane 1.5 mm is manufactured under ASTM standards (ASTM D-5199, ASTM D-6693…) and the Vietnamese standard TCVN 10812:2014 for HDPE membranes.

• Roll width: commonly 6–8 m; length as per order.
• Thickness control ±5% per roll.
• Carbon black content (≥2%) for UV protection.
• Factory testing: thickness, tensile strength, permeability, and static water pressure resistance.

Key mechanical indicators: tensile strength and deformation resistance

• Tensile strength: typically ≥25 kN/m depending on thickness.
• Elongation at break: around 700% or higher for flexibility.
• Tear and puncture resistance: ensures the membrane withstands sharp objects.
• Creep resistance: maintains shape under long-term pressure.
• Permeability: <1×10⁻¹³ m/s ensuring absolute waterproofing.

Waterproofing and chemical resistance in construction environments

The HDPE waterproofing membrane 1.5mm Visco is designed to endure construction conditions:

• Provides absolute waterproofing when welded correctly.
• Resistant to chemicals, mild acids, and alkalis found in concrete and soil.
• UV and aging resistant thanks to carbon black; suitable for outdoor use.
• Thermally stable between –40°C to +80°C without deformation.

Applications of HDPE waterproofing membrane 1.5mm in infrastructure construction

Use in foundations and basements of high-rise buildings

Basements and foundations under groundwater pressure require strong waterproofing. The 1.5mm HDPE membrane forms an external barrier on retaining walls and pits, reducing seepage and protecting the concrete structure.

Use in technical water tanks and industrial treatment basins

Technical and wastewater tanks require absolute waterproofing. 1.5mm thickness is ideal to handle vertical water pressure and ground stresses without leakage.

Use in roads, bridges, and urban infrastructure

For roof waterproofing, expansion joints, utility pits, and protection layers, the HDPE waterproofing membrane 1.5mm acts as a seal between concrete and covering layers, minimizing cracking and seepage from thermal and structural movements.

Installation guide for HDPE waterproofing membrane in construction

Standard installation and welding process

1. Prepare the surface: level ground, remove sharp objects, place protective layer (geotextile or fine sand).
2. Unroll the HDPE membrane with 10–15 cm overlap.
3. Hot wedge or extrusion weld with correct temperature and speed.
4. Reinforce corners and penetrations.
5. Perform leak and vacuum tests.

Checklist before completion:

• Joints meet tensile standards.
• No wrinkles or trapped debris.
• Edges clean, sealed properly.
• Leak test passed.

Weld inspection and quality assurance

• Use non-destructive testing (helium, pressure, vacuum).
• Visual inspection for discoloration or defects.
• Pull test for sample welds.
• Document inspection reports before concrete coverage.

Precautions for humid or concrete surfaces

• Avoid wet or flooded substrates; ensure dryness.
• Level new concrete surfaces before laying.
• Avoid welding below 5°C or above 50°C.
• Provide mechanical anchoring on slopes or hydraulic zones.
• Do not overstretch membrane; allow for thermal movement.
