Overview

EN 15815:2011 specifies a standardized laboratory procedure to determine the resistance to compression of polymer‑modified bituminous thick coatings used for waterproofing. Published by CEN, this test method defines specimen preparation, conditioning, measurement equipment, test execution and pass/fail criteria to assess how these thick bituminous coatings compact under long‑term compressive load.

Keywords: EN 15815:2011, polymer modified bituminous thick coatings, resistance to compression, waterproofing test method, CEN.

Key topics and requirements

• Scope: Test method for compression (stauchung) resistance of polymer‑modified bituminous thick coatings for waterproofing.
• Specimens: Square specimens ~20 cm × 20 cm, applied onto concrete supports (≥ 20 × 20 cm area, ≥ 4 cm thick, minimum quality C20/25, ≥ 28 days old).
• Coating thickness: Wet application to achieve manufacturer‑specified dry thickness (typically ≥ 3 mm or 4 mm) within ±10% tolerance; finished specimens conditioned for 28 days.
• Conditioning and test climate: Normal climate (23 ± 2) °C and relative humidity (50 ± 5) % in accordance with ISO 554 for preparation and testing.
• Apparatus and measurement:
  • Flat base (≥10 mm diameter, accuracy 10 µm), extensometer or vernier caliper, micrometer and measuring marks.
  • Thickness measured at multiple points (16 or 12 readings depending on step) with defined averaging procedures.
• Procedure:
  • Preliminary load of 0.01 MN/m² applied; mean initial thickness S0 computed.
  • Main load applied in accordance with FprEN 15814:2011.
  • Daily thickness measurements; at least three specimens tested (stacking allowed with separating layer).
• Pass/fail criteria:
  • After 5 days the mean reduction in thickness must be < 50% of initial thickness.
  • Stabilisation: change over the last three days (e.g., S5 − S2) must be ≤ 3%.
  • If not stabilized, test may be extended up to 40 days until criteria are met (overall change ≤ 50% and three‑day change ≤ 3%).
• Test report: Product identification, reference to EN 15815, specimen preparation, test pressure and conditions, results and test dates.

Applications and users

This standard is used by:

• Manufacturers of polymer‑modified bituminous thick coatings for product development and conformity testing.
• Independent testing laboratories performing durability and compressive resistance tests.
• Specifiers, consultants and architects who require validated performance data for waterproofing systems.
• Certification bodies and regulators that reference CEN methods for product approval and compliance.
