Polymer modified bituminous thick coatings for waterproofing - Determination of crack bridging ability

This European Standard specifies two methods (method A and method B) for determining the crack bridge properties of polymer modified bituminous thick coatings for waterproofing. The two test methods may be applied equally.

Bitumenske debeloslojne prevleke za tesnjenje, modificirane s polimeri - Določanje sposobnosti premoščanja razpok

Ta evropski standard določa dve metodi (metodo A ali metodo B) za določanje sposobnosti premoščanja razpok bitumenskih debeloslojnih prevlek za tesnjenje, modificiranih s polimeri. Preskusni metodi se lahko uporabljata enako. Ta evropski standard je bil pripravljen za uporabo pri podzemnih strukturah, lahko pa se uporablja tudi na drugih območjih, kjer je hidroizolacija pomembna, npr. na balkonih ali v vlažnih prostorih.

Overview

EN 15812:2011 is a European standard developed by CEN that specifies methods for determining the crack bridging ability of polymer modified bituminous thick coatings used for waterproofing. The standard defines two equivalent test methods-Method A (bending test) and Method B (tensile test)-which assess how effectively these polymer-modified bituminous coatings can bridge or seal cracks without damage when applied on concrete substrates. This evaluation is crucial for ensuring the long-term durability and water tightness of waterproofing coatings in construction and civil engineering applications.

Key Topics

• Scope and Purpose
  EN 15812:2011 focuses on the test methods for measuring crack bridging properties of polymer modified bituminous thick coatings. Crack bridging ability is the capacity of the coating to stretch across a crack under specified conditions without exhibiting damage or failure.

• Test Methods

  • Method A: Bending Test
    Involves applying the coating on a reinforced concrete slab (300mm × 200mm × 40mm), then inducing bending deformation with controlled crack width enlargement at a test temperature of 4°C ± 1°C. The crack width is typically extended to 2 mm and held for 24 hours, followed by visual inspection for cracks.
  • Method B: Tensile Test
    Utilizes a smaller concrete slab (150mm × 150mm × 40mm) and a tensile machine setup with tie rods to stretch the coated surface. The same crack width and temperature conditions are applied, with subsequent inspection for coating integrity.

• Sample Preparation and Conditioning
  Concrete substrates are fabricated and cured as per EN 1766:2000 requirements, with moisture and temperature conditioning before and after coating application. The coating thickness is controlled to a minimum of 3 mm dry layer, ensuring consistency for accurate test results.

• Test Conditions and Evaluation
  Testing is performed at low temperatures (around 4°C) to simulate challenging environmental conditions. The crack width is controlled precisely using measurement sensors to maintain consistency. Passing criteria require no visible cracks on at least two out of three specimens.

• Reporting
  Detailed test reports are required including references to EN 15812, product identification, test method used, coating thickness, temperature, test speed, and results.

Applications

EN 15812:2011 is essential for manufacturers, engineers, and quality control laboratories involved in:

• Waterproofing Systems
  Ensuring polymer modified bituminous thick coatings maintain crack bridging performance protects concrete structures against water ingress, preventing damage and prolonging structural life.

• Construction and Civil Engineering
  Applicable to waterproofing in tunnels, basements, bridges, and other infrastructure where crack movement is expected due to thermal changes or settlement.

• Product Development and Compliance Testing
  Verification of crack bridging properties is critical when designing new polymer-modified bituminous coatings for enhanced flexibility and durability.

• Quality Assurance
  Provides standardized testing to confirm manufacturer claims and compliance with European waterproofing material regulations.
