Concrete - Specification, performance, production and conformity - Part 3: Additional requirements for specification and conformity of concrete for special geotechnical works
(1) This document specifies additional requirements to prEN 206 1 for the constituents, specification and conformity control of concrete used in:
- bored piles constructed in accordance with EN 1536;
- diaphragm walls constructed in accordance with EN 1538;
- cast-in-place displacement piles constructed in accordance with EN 12699;
- micropiles constructed in accordance with EN 14199.
(2) The requirements provided in this document are specified in accordance with prEN 206 1:2024, 7.2 Specifications for designed concrete.
(3) This document can also apply to applications in special geotechnical works other than those listed above.
NOTE 1 For special geotechnical works provisions on cement, minimum cement content, minimum fines content, maximum water/binder ratio, target values of fresh concrete properties and maximum tolerances for target values can deviate from the provisions for other works in prEN 206 1.
(4) This document is based on the assumption that the specification is based on considerations including the site conditions and the conditions for execution of concrete used in special geotechnical works.
NOTE 2 Guidance for the specification of concrete used in special geotechnical works can be found in the informative Annex A.
Beton - Festlegung, Eigenschaften, Herstellung und Konformität - Teil 3: Zusätzliche Anforderungen an die Festlegung und Konformität von Beton für spezielle geotechnische Arbeiten
(1) Dieses Dokument legt zusätzlich zu prEN 206 1 Anforderungen an die Ausgangsstoffe, Festlegung und Konformitätskontrolle von Beton fest, der verwendet wird in:
- Bohrpfählen, die nach EN 1536 hergestellt werden;
- Schlitzwänden, die nach EN 1538 hergestellt werden;
- Ortbeton Verdrängungspfählen, die nach EN 12699 hergestellt werden;
- Mikropfählen, die nach EN 14199 hergestellt werden.
(2) Die Anforderungen, die in diesem Dokument bereitgestellt werden, sind in Übereinstimmung mit prEN 206 1:2024, 7.2, Festlegungen für Beton nach Eigenschaften, festgelegt.
(3) Dieses Dokument kann auch für andere als die vorstehend aufgeführten Anwendungen bei besonderen geotechnischen Arbeiten gelten.
ANMERKUNG 1 Für besondere geotechnische Arbeiten können die Festlegungen für Zement, Mindestzementgehalt, Mindestgehalt an Mehlkorn, Höchstwert des Verhältnisses Wasser/Bindemittel, Zielwerte für Eigenschaften von Frischbeton und höchstzulässige Grenzabweichungen für Zielwerte von den Festlegungen für andere Arbeiten in prEN 206 1 abweichen.
(4) Dieses Dokument beruht auf der Annahme, dass die Festlegung auf Betrachtungen einschließlich der Standortbedingungen und der Bedingungen für die Ausführung von Beton, der bei speziellen geotechnischen Arbeiten verwendet wird, basiert.
ANMERKUNG 2 Hinweise für die Festlegung von Beton, der bei speziellen geotechnischen Arbeiten verwendet wird, können dem informativen Anhang A entnommen werden.

European foreword
This document (prEN 206-3:2024) has been prepared by Technical Committee CEN/TC 104 “Concrete
and related products”, the secretariat of which is held by SN.
This document is currently submitted to the CEN Enquiry.
This document will partially supersede EN 206:2013+A2:2021.
EN 206-3 was based on the contents of Annex D (Additional requirements for the specification and
conformity of concrete for special geotechnical works [foundation engineering]) from the previous
EN 206:2013+A2:2021. Annex D has been completely incorporated into EN 206-3. In particular, the
following new key points were included in the development of EN 206-3:
a) testing standards on fresh concrete properties as an addition to the EN 12350-series;
b) reference to non-specified material like cementitious compound, clay minerals or “special
admixtures”;
c) reference to temporary works;
d) reference to non-structural members.
This document forms part of three European Standards, written by CEN/TC 104 and covering
specification, performance, production and conformity of concrete.
— Concrete — Specification, performance, production and conformity — Part 1: Performance,
requirements, factory production control and assessment criteria for individual values.
— Concrete — Specification, performance, production and conformity — Part 2: Conformity
assessment and certification.
— Concrete — Concrete — Specification, performance, production and conformity — Part 3: Additional
requirements for specification and conformity of concrete for special geotechnical works
0 Introduction
0.1 Introduction to prEN 206-3
(1) This document defines tasks for the specifier, producer and user.
(2) If the concrete is in conformity with this document or provisions in prEN 206-1 and prEN 206-2, the
concrete in the structure is deemed to satisfy the durability requirements for the intended use in the
specific environmental condition, provided:
— the appropriate exposure classes were selected;
— the concrete has the minimum cover to reinforcement in accordance with the relevant design
standard required for the specific environmental condition, e.g. EN 1992-1-1;
— the concrete is properly placed, compacted and cured, e.g. in accordance with EN 13670 or other
relevant standards;
— the appropriate maintenance is applied during the working life.
(3) This document deals with parts of the interface between prEN 206 and standards for the execution
of special geotechnical works, see Figure 1.

geotechnical works – concrete related standards
0.2 Provisions valid in the place of use for prEN 206-3
(1) This document will be applied under different climatic and geographical conditions, different levels
of protection and under different, well established, regional traditions and experience. Classes for
concrete properties have been introduced to cover these situations. Where such general solutions were
not possible, the relevant clauses contain permission for the application of provisions valid in the place
of use of the concrete.
(2) National choice is allowed in this document where explicitly stated that provisions valid in the place
of use may be given.
(3) The national standard implementing prEN 206-3 can have a National Annex or complementary
standard containing all national choices to be used in the relevant country.
(4) National choice is allowed in prEN 206-3 in the following:
4.1 (1) 4.1 (2) 4.2 (1) 4.3 (4)
4.6 (1) 4.6 (2) 5.1 (1) 5.4.1 (3)
NOTE The National Annex can contain, directly or by reference, non-contradictory complementary information
for ease of implementation, provided it does not alter any provisions of this document.
1 Scope
(1) This document specifies additional requirements to prEN 206-1 for the constituents, specification
and conformity control of concrete used in:
— bored piles constructed in accordance with EN 1536;
— diaphragm walls constructed in accordance with EN 1538;
— cast-in-place displacement piles constructed in accordance with EN 12699;
— micropiles constructed in accordance with EN 14199.
(2) The requirements provided in this document are specified in accordance with prEN 206-1:2024, 7.2
Specifications for designed concrete.
(3) This document can also apply to applications in special geotechnical works other than those listed
above.
NOTE 1 For special geotechnical works provisions on cement, minimum cement content, minimum fines content,
maximum water/binder ratio, target values of fresh concrete properties and maximum tolerances for target values
can deviate from the provisions for other works in prEN 206-1.
(4) This document is based on the assumption that the specification is based on considerations including
the site conditions and the conditions for execution of concrete used in special geotechnical works.
NOTE 2 Guidance for the specification of concrete used in special geotechnical works can be found in the
informative Annex A.
