KRAMPEHAREX® FIBRES – for top performance in fibre concrete and concrete precast elements

As a specialist and technology leader in the field of fibre technology with more than 35 years of experience and a great ability to deliver and provide superior service, we ensure the stability and durability of concrete right around world – and facilitate innovative construction projects in a wide range of applications.
Applications
Tunnel construction
Shotcrete, cast-in-place concrete, tubbings: KrampeHarex® fibres provide fast and cost-effective reinforcement including fire protection.

View
Industrial floors
High-quality, cost-effective, durable and low-maintenance: Steel fibre concrete floors with KrampeHarex® fibres.

View
UHPC
Ultra-high-strength concrete with KrampeHarex® fibres is used to manufacture exceptionally thin but extremely robust components.

View
Traffic areas
Less work, maximum safety and a highly durable surface – this is what steel fibre concrete offers the road construction sector.

View
Concrete precast elements
KrampeHarex® fibres are the ideal reinforcement for pipes, shafts, tubbing segments, pre-fab cellars and other concrete precast elements.

View
Security technology
Extremely impact-resistant and highly resistant to dynamic loads: Bank vaults and cashpoints made of steel fibre concrete.

View
Residential construction
KrampeHarex® fibres made of steel, polypropylene and glass make residential buildings faster to construct, less expensive and longer lasting.

View
Refractory concrete
KrampeHarex® steel and stainless steel fibres increase resistance to the effects of heat and prevent high-temperature corrosion.

View
Mines
Reinforce mine walls quickly and simply with steel fibre concrete: KrampeHarex® fibres provide maximum safety.

FLEXIBLE ALL-ROUNDERS FOR INNOVATIVE CONSTRUCTION.

From steel fibres through glass fibres to fibres made of plastic – the KrampeHarex®  product range is as diverse as the construction and planning projects of general contractors and engineers.


The supply situation never gets particularly tight, because we have been drawing our own wire ever since 2003, enabling us to control the entire value chain from the feedstock through to the finished fibres. This also enables us to guarantee consistently high quality for all steel grades and fibre geometries. Specialist fibres, such as KrampeFibrin® polypropylene fibres, comply with special requirements such as fire resistance ratings F60 and F90.

No matter what your construction project comprises and what requirements you have to meet, we’ll work with you to find the ideal fibre solution.

Advantages
Know why
Every KrampeHarex® fibre is a promise
From industrial floors that are driven on by vehicles with hard tyres and heavy loads, through tunnels that have to withstand extreme loads and blast furnaces that are exposed to great heat, to structurally relevant assemblies in silo constructions – KrampeHarex® fibres enable concrete structures to comply with the most stringent requirements for safety, stability, wear and fire resistance. With innovative solutions, outstanding quality management and our Service+ philosophy, we guarantee that customers located in more than 50 different countries are satisfied with what we give them. Even when it’s necessary to meet demanding deadlines and deliver large quantities of fibres within the shortest possible time.

Quality management

Certified according to ISO 9001:2015 – we monitor every phase of production in accordance with strict criteria.

SERVICE+

Service from A–Z: Engineering support, construction supervision, special solutions, rental service for dosing devices.

STATE OF THE ART

We meet the building standards of the DASFB and DBV (German Society for Concrete and Construction Technology) as well as international standards.

GREAT ABILITY TO DELIVER

We deliver fast and in large quantities because we produce the wire for the fibres ourselves.

RESPONSIBILITY

We take full responsibility for the stability of the structural design computed by our engineering partner.

EXTREMELY COST-EFFECTIVE

Fibre concrete guarantees rapid construction progress, low material costs and a long service life.

OPTIMUM CONCRETE PROPERTIES

Our fibres optimise contraction and post-cracking behaviour, distances between joints, fire resistance, etc.

COMBINED SOLUTIONS

We exploit the synergies of different types of reinforcement and find the best solution for every application.

ENVIRONMENTAL PLEDGE

We manufacture our products using 100% green electricity, and believe in high-efficiency technologies and eco-friendly disposal.

An investment in knowledge is the most profitable.

High-performance road surfaces

KrampeHarex® fibres are also ideal when searching for innovative solutions in road construction. Using fibre concrete makes it possible to build high-performance road surfaces that feature outstanding structural integrity, great longevity, fast construction and excellent cost-effectiveness. We were involved in three projects in Rotterdam (NL), Kerpen (D) and Leuven (BE).

Amazon – Built on KrampeHarex®

A transhipment point for millions of products needs a firm foundation: Amazon’s second biggest warehouse in Germany, built in 2008 in Bad Hersfeld, stands on a 100,000 m² floor slab made from 22,000 m³ of steel fibre-reinforced concrete. Amazon chose KrampeHarex® fibres for this purpose, both here and at its Rheinberg warehouse, which was erected 3 years later. For good reason, too.

NEW BENCHMARKS IN FIRE PROTECTION

The Leipzig City Tunnel, completed in 2008, was the first of its kind to meet these especially high fire protection requirements. The tubbing segments for lining the tunnel are reinforced with KrampeHarex® polypropylene fibres. An innovative step that has set new benchmarks. The exact dosage of the fibres also proved to be exceedingly important.
