A Manufacturers Perspective: Concrete Repair and Protection Standard EN 1504 What it covers, how to use it and its limitations Hein Ehbrecht
Europa: countdown; Schwarzkopf Stiftung, 03.5.2012
„Just a Minute! I‘ve got good news for you! If you consider it, the solution is already cast in stone in the European Constitution Contract: „Europe of the Regions". The Regions are the Wealth of this Continent, the Nations however are historically exhausted Identity Phantasies and it is necessary to overcome this Threat.“ Speach of Robert Menasse, Austrian Writer and Pro-European – translation H.E.

...art can be a powerful way to overcome barriers in Europe and beyond...
Europe: Great – but do we really need this new CPR, EN 1504 – and > 400 hEN‘s?
Content: The New European Construction Products Regulation (CPR) and its impact on National Standards for Concrete Repair and Protection, hEN 1504 Example: EN 1504, Part 2 / Declaration of Performance (DoP) giving minimum requirements / CE-labelling EN 1504-2 (H/I/C) and how to use it on Concrete Structures based on general principles (part 9) and performance criteria Limits of 1504 and what is not covered (Examples given)
National Building Regulations vs. European Regulations? National boundaries still apply in relation to many technical building regulations. This is despite the desire in the European Treaties from the very outset to prevent restrictions on trade created by national laws or national regulations. Harmonized European Standards (hEN‘s) and the new CPR are an important step not only to overcome trade barriers but also to give „more freedom to the designer“. EN 1504, the harmonized European „Concrete Repair and Protection Standard“ - a good example to demonstrate this, but also to show its limitations.
CPR and hEN‘s: Harmonization demand
No doubling up of regulations Clarity with regard to the performance requirements
No national additional regulations; instead steps and classes in the hEN-standards to select from Clear definition of the areas of use Short: Simpler, clearer, lesser administration: To create a real, unified EU-wide internal market for building products, ruled by the same standards and performance criteria throughout the EU
…this means Harmonized legal framework structure, mutual recognition, directive can be used directly, nationale standards must be withdrawn (no longer a need for it)
Requirement for being precise (performance – based vs. describing), gives „freedom to the designer“
CE-label being a reliable mark in combination with the Declaration of Performance (DoP)
Simplification via European Technical Assessment, a system of harmonized technical specifications and an agreed system of attestation of conformity for each product family – see examples EN1504-2 with DoP‘s for products and areas of use
Essential Requirements for Structures and Construction Products, Regulation (EU) No. 305/2011, dated 9.3.2011 1. 2. 3. 4. 5. 6. 7.
Mechanical Strength and Stability Fire Protection Hygiene, Health and Environment + Climate… Safe to use + Barrier – free .... Sound Protection Energie saving and heat insulation Sustainable usage of natural resources Mandate of Com to CEN Harmonisized European Standard (hEN) Note: There are over 400 hEN‘s so far, covering a broad range of construction products
Declaration of Performance (DoP) The new DoP replaces the previous EU-Declaration of Conformity
The DoP must be designed on the basis of a technical documentation. Both must be filed for 10 years (Art. 11)
The DoP must be made available in the language required in the Member States, where the construction products is been put into the market (Art. 6 (4))
The DoP must be made available from 01.07 2013 for all construction products of relevance, means where a CE is required / falls under a hEN. (Art. 68)
Declaration of Performance (DoP) The DoP must be made available in electronic or in printed format, from the first day the product is introduced into the market. (Art. 7 (1))
On request of the user the DoP must be made available in printed format (and not only electronic). (Art. 7 (2))

Permissible National „Kite Marks“?
generally? – no If additional benefit? – yes (see our example product Emcephob NanoPerm P for such additional benefits)
With regard to European Conformity? - no
EU- Construction Products Regulation
Requirements for Specifiers and Designers outlined by the Irish DOE: Whilst the CPR concerns itself with the conditions which apply when placing a product on the market, clients, specifiers and designers should: When drawing up specifications, refer to the harmonised technical specifications Choose products most suitable for their intended use in construction works, review the manufacturer’s declaration of performance; Check the appropriate minimum performance levels required for specific intended use. Comment: ask for higher performance levels / additional benefits
Why the need for remaining directives ? Example: DIN EN 1504-2 (SP) Note: 2 basic rules are important to understand: a) Harmonized Product Standards must be used in each MS without changes b) The rules for the use of products are set nationally (i.e. D: ZTV SIB / Irl: ?) I.S. EN 1504-2 does not contain a DoP for a tested and approved system, but for single products. German Concrete Repair directives SIB / ZTV ING does:
Example: System-build-up SP C (ZTV-ING) consists of layers, i.e. fine filler and coating (incl. Primers)
Consequence: I.S. EN 1504-2 is without a national adaption not useful / safe in areas of static design! Products acc, to I.S. EN 15042 with CE

…and now?? - The Freedom of the Designer
Concrete Protection (and Repair) Surface Protection to EN1504-2 Examples / how to work with the Standard
EN 1504 – What it covers Part 1: Definitions Part 2: Surface Protection Systems Part 3: Structural and Non-structural Repairs (Mortars) Part 4: Structural Bonding Part 5: Concrete Injection Part 6: Grouting / Anchoring Part 7: Reinforcing Corrosion Protection Part 8: Quality Control and evaluation of conformity Part 9: General Principles for the use of products (the above parts) Part 10: Site application of products and quality control of the works
11 No‘s of General Principles – EN 1504-9 Part 1504-9 details the 11 No‘s of basic (repair-, strengthening- and protection-) principles, which shall be used, separately or in combination, where it is necessary to repair or to protect concrete structures, above or below ground or water.
Methods from parts 2-7 are used, based on the principles together with the repair and protection concept, developed by the competent planner / designer in the outlined key stages (see next) for such a repair concept.
Key Stages according to EN 1504-9 Repair and Protection Concept
Assessment of the condition of the structure Identification of the cause of the deterioration Setting of targets and deciding on objectives Selection of the required principle(s) of repair and protection Method (s) selection Product Selection / (System Selection) Note: The competent Planner / Designer selects products in acc. To 1504, Parts 2-7, based on Performance Criteria (See DoP‘s) for the selected Methods.
Principles EN1504-9 Adressing Concrete Damage and Surface Protection (1-6): Principle 1 (IP): Protecion against Ingress Principle 2 (MC): Moisture Control Principle 3 (CR): Concrete Restauration Principle 4 (SS): Structural Strengthening Principle 5 (PR): Physical Resistance Principle 6 (RC): Resistance to Chemicals Adressing Reeinforcement Corrosion: Principle 7 (RP): Preserving or Restoring Passivity Principle 8 (IR): Increasing (electrical) Resistivity Principle 9 (CC): Cathodic Control Principle 10 (CP): Cathodic Protection Principle 11 (CA): Anodic Control
Evaluation / Comment on the Concept „Freedom for the Designer“ Advantages: Product Selection possible to get an exact „Performance Profile“ required for a particular project More Planner-Flexibility in comparison to „class selection“ (i.e. See German ZTV-ING) Disadvantages: High planning effort / cost, high planning responsibility Danger of wrong decisions / wrong selections resulting from complexity High level of knowledge required (training/experience)
Some important Technical Requirements for Surface Protection Systems for Structures above Ground to consider
Resistance against water vapour „< 4 m“
Water repellent / water ingress control
Resistance against CO2 „ > 50 m“
Not applicable for hydrophobic „Impregnations“ (EN1504-2 (H))
UV – resistance / Long-term Performance
Further technical requirements shown in 1504-2 ..., showing test standards Crack-bridging (dynamic and static) Frost / thaw resistance Physical resistance (impact and abrasion) for
foot traffic and vehicle traffic Skid resistance (EN13036-4, was BS 7976, Pendulum Test) Chemical resistance Fire resistance Adhesion strength, etc….
