South Africa
Year of intervention: 1992
The South African railway network is extremely extensive and connects coal deposits to ports. Due to the continuous contact of water and the presence of reactive silicas, dangerous cracks have formed that can compromise the stability of the railway network. The treatment with Protectosil BHN, pure alkyl alkoxy silane solvent less, inhibits the entry of water and blocks the expansion of the aggregated alkalis, preserving the railway structure and ensuring high durability over time.
