What is BS EN 14475 - reinforced fill for geotechnical works about?
BS EN 14475 establishes general principles for the construction of reinforced fill.
BS EN 14475 covers engineered fills that are reinforced by the inclusion of horizontal or subhorizontal reinforcement placed between layers of fill during construction.
The scope of reinforced fill applications considered in BS EN 14475 includes:
- Earth retaining structures, (vertical, battered, or inclined walls, bridge abutments, bulk storage facilities), with a facing to retain fill placed between the reinforcing layers
- Reinforced steep slopes with a facing, either built-in or added or wrap-around, reinforced shallow slopes without a facing, but covered by some form of erosion protection without a facing, reinstatement of failed slopes
- Embankments with basal reinforcement and embankments with reinforcement against frost heave in the upper part
Principles for the execution of other special geotechnical works using soil nails, bored piles, displacement piles, micro piles, sheet pile walls, diaphragm walls, grouting, or jet grouting are established in other European Standards.
Note: Reinforcement of road pavements is not covered by BS EN 14475.

Why should you use BS EN 14475 - reinforced fill for geotechnical works?
Reinforced soil slopes are compacted fill embankments with geosynthetic reinforcement placed horizontally to provide a stable, oversteepened slope structure.
BS EN 14475 provides guidance on the general principles for reinforced fill for geotechnical works.
BS EN 14475 guidelines help you to deal with unforeseen circumstances or with any conditions revealed or considered during construction which appear to be worse than those assumed in the design as well as to avoid damage to existing or proposed services.
BS EN 14475 provides geotechnical, hydrogeological, and hydrological guidelines to enable the constructor to design any temporary works or accesses needed for construction (e.g. earthworks, embankments, stabilization of excavations or cuttings near the structure, construction of cofferdams.
BS EN 14475 guidelines enable you to build reinforcement structures that meet the stated standards for safety, serviceability, economy, and durability while taking into consideration the estimated service life.
