solidian’s carbon or glass fibre solutions offer tensile strengths five to six times greater than conventional steel reinforcements, and building with textile-reinforced concrete is especially safe. Building with textile-reinforced concrete generally avoids the unsightly concrete spalling and other visible damage that is caused by large cracks. In addition to their resistance to corrosion, textile reinforcements also enhance safety and sustainability in construction. The high tensile strength of solidian’s high-performance materials is a product of technologically advanced fibre and impregnation systems, which are tailor-made for achieving material properties requirements.
So, highly stressed components use carbon reinforcements with a breaking strength of over 3,000 N/mm² - five to six times that of comparable steel reinforcements. Such high strength is not normally required for components facing lower stresses. In such cases, relatively economical glass fibre reinforcements are used. solidian manufactures every currently significant textile reinforcement under one roof. In this way, we can offer our clients the most technically appropriate and most economical solution - something unique in the world market.
The particular superiority of textile-reinforced concrete becomes apparent with the optimum combination of carbon and/or AR glass reinforcement and impregnation materials using epoxy resin or styrene butadiene. Bonding behaviour can thus be optimally customised for the building or other specific application. Depending on the chosen combination of fibre and impregnation material, the bonding properties can be adjusted as desired. Textile reinforcements are thus even suited for waterproof concrete components requiring a maximal crack width of 0.1 mm - not a problem for solidian GRID.

Depending on the impregnation material, textile reinforcements exhibit excellent bonding behaviour. Tests have shown that, depending on the roving cross-section and the concrete selected, anchorage lengths of less than 20 mm can be achieved. Compared to steel-reinforced concrete, this leads to a very dispersed crack pattern, sometimes less than 0.1 mm while in service.
As a result of their excellent bonding behaviour, textile-reinforced elements exhibit remarkable crack formation, e.g., many dispersed cracks with small crack widths. As a rule, the cracks are so small that they cannot be seen with the naked eye while in service, which is a construction specification often only achieved with steel-reinforced concrete by adding extra reinforcement (“anti-crack reinforcement”). Here again, the right combination of fibre and impregnation material is key: Our experts will recommend the material that is just right for your specific application.
