Applications and audiences

Fibre reinforcement is not a niche solution for one type of structure, but a technique that adds value across a wide range of sectors and applications. Who benefits varies considerably: a municipality managing an extensive road network and dozens of bridges on a limited budget looks for quite different advantages than a precast factory where every minute and every kilo counts. On this page we bring together who fibre reinforcement of concrete and asphalt is relevant for, in which applications it proves itself — from sand-cement screeds and power-floated concrete floors to concrete retaining walls and car parks — and how to choose the right supplier, with an in-depth article for each topic.

For public authorities and road managers

Municipalities manage most of the Dutch road network, often on tight budgets. Fibre reinforcement extends the service life of asphalt and concrete and is directly applicable within existing maintenance contracts — without requiring an entirely new specification. Provinces, in turn, have the scale and expertise to act as a proving ground for innovative road materials; for them it is mainly about how to incorporate fibre reinforcement into EMVI tenders and multi-year maintenance programmes. And anyone who has to replace a worn timber bridge deck faces a material choice — composite, plastic or fibre concrete — in which low maintenance and service life are decisive. The comparison for bridge deck replacement sets a composite GRP deck, recycled plastic planks and precast fibre reinforced concrete side by side on service life, maintenance, weight, price and circularity. In every case the common thread is the same: lasting longer with less maintenance within the frameworks the organisation already uses.

For construction and industry

For contractors, fibre reinforcement is more than a sustainability story for the client: it saves labour hours, lowers failure costs and provides scoring arguments for the EMVI plan. At concrete plants the question shifts to the production process itself: how do you integrate fibre reinforced mixes into the existing recipe, and how do you safeguard dosage, homogeneity and quality control? And in the precast factory, where every minute and every kilo counts, structural synthetic fibre largely replaces the reinforcement in precast concrete elements, speeds up production and, in practical examples, substantially lowers the MKI score. The guide to fibres for precast concrete compares synthetic macro, steel, micro, basalt and AR glass fibres, with indicative dosages per element type. Every link in the chain has its own angle, but they share the same benefit: working faster with less material.

Sectors with special requirements

Some sectors have requirements where traditional reinforcement falls short. In the agricultural sector, barn floors, yard pavements and slurry pits face chemical exposure, heavy use and permanent moisture — conditions in which corrosion of reinforcing steel is a real problem. Synthetic and basalt fibre offer a corrosion-free answer here. The article on agricultural concrete reinforcement gives slab thickness and fibre dosage per application, from barn floors and silage clamps to yard paving. The same applies in greenhouse horticulture, where vast, continuous concrete floors are poured on sand, stand under moisture and chemical loading and must carry intensive transport traffic. It is precisely in these demanding environments that non-corrosive fibres show their added value.

Outdoor applications

Outdoors, fibre concrete proves itself where paving is heavily loaded. Concrete retaining walls — often precast L- or T-elements — retain soil and loads and benefit from fibre reinforcement in both production and service life. Every type of concrete retaining wall, from a 30 cm garden wall to a 3 metre silage clamp wall, is worked out in a separate article with its section, dimensions, concrete grade and price per metre. With white topping, a thin fibre concrete layer is applied over existing asphalt to give ageing pavement a second life. How white topping concrete works, which layer thicknesses and joint spacings apply and when it pays off is explained step by step. And car parks and parking decks have their own loading profile with a lot of stop-start movement and concentrated point loads, which fibre reinforcement of both asphalt and concrete addresses well.

Floors and finishing

In floors, crack control plays the leading role. Shrinkage fibre limits cracking in the sand-cement screed, and in a floating screed — laid on insulation, often with underfloor heating — thermal cycling and the resilient substrate make fibre reinforcement almost always necessary. The same story applies to the finish: a power-floated concrete floor calls for a monolithic, low-joint design in which fibres replace the steel mesh without affecting the mirror-smooth surface, and outdoors synthetic fibres form a rust-free alternative to the mesh in power-floated patio floors. The article on sand cement screed gives the thickness per type, drying time and mix ratio, the explainer what is a floating screed covers the build-up layer by layer with the minimum thickness per screed type, and the guide to the power floated concrete floor covers the process, specification and cost per m².

Choosing a supplier

Once the application is clear, the question becomes who you buy the concrete fibres from. Fibre type, quality, dosage advice and technical substantiation differ per supplier — and a choice based on price alone rarely works out well. A well-considered decision looks at the reasoning behind the advice and the quality of the material, not just the price per kilo. The articles below each work out these audiences, applications and choices in more detail.
