Overview

EN 15820:2011 is a European Standard developed by CEN that specifies a standardized procedure for determining the watertightness of polymer modified bituminous thick coatings used for waterproofing. The standard focuses on assessing the resistance of these coatings to hydraulic pressure, ensuring their effectiveness in preventing water penetration under pressure conditions. This test provides a critical quality measure for waterproofing materials used in construction and civil engineering projects.

Key Topics

• Scope
  Defines a reliable test method to evaluate the watertightness of polymer modified bituminous thick coatings by applying a controlled hydraulic pressure.

• Test Principle
  The method involves subjecting circular test specimens made from the bituminous coating to specified water pressure for at least 24 hours. A slotted plate applies pressure through defined slots, enabling an evaluation of whether any water leaks through the specimen.

• Test Apparatus
  Includes a pressure application device with a circular slotted plate covering the specimen, guaranteeing uniform water pressure application over the test surface.

• Specimen Preparation and Conditioning
  Test membranes are prepared following thickness classes defined in related standards and conditioned for 28 days at controlled temperature and humidity (23 ± 2 °C, 50 ± 5% RH) to simulate real-world conditions before testing.

• Testing Procedure
  Water is filled into the apparatus, specimens are placed face downwards, and pressure is gradually increased and maintained according to product specifications. Watertightness is confirmed by the absence of water leakage on the specimen's non-exposed side.

• Result Evaluation
  A specimen passes the test if no water leakage occurs during the specified pressure application time, which is a minimum of 24 hours.

• Test Reporting
  The standard mandates detailed recording of product identification, test parameters (pressure, duration, specimen thickness), deviations, and results for transparency and reproducibility.

Applications

• Construction Waterproofing
  Ensures the reliability of bituminous coatings used in foundations, basements, tunnels, and earth-retaining structures where resistance to water pressure is critical.

• Civil Engineering Projects
  Validates waterproofing membranes employed in infrastructure exposed to groundwater or hydraulic pressure, such as retaining walls and underground pipelines.

• Quality Control
  Assists manufacturers and specifiers in quality assurance by providing a repeatable method to confirm waterproofing performance meets stringent European requirements.

• Product Development
  Guides formulation improvement by offering comparative data on coating resistance to water penetration under pressure.

Related Standards

• FprEN 15814:2011 – Defines terminology and performance requirements for polymer modified bituminous thick coatings, complementing EN 15820 by clarifying coating classifications.

• ISO 554 – Specifies standard atmospheres for conditioning and testing, ensuring consistent environmental test conditions for specimens.

• Other Waterproofing Standards – EN 15820 should be used alongside other standards governing waterproofing systems for comprehensive assessment and product certification.
