ABSTRACT
Underground infrastructures are becoming more and more of utmost importance for designer, construction companies and suppliers as it is necessary to adopt new approaches to build durable infrastructures and to refurbish the existing ones with rapid and efficient methods.
It is important that the construction products are engineered to satisfy the main urgent and long-term objectives, such as mechanical properties and durability under the specific condition of use, and to match the required timing necessary to fulfill the goals under safety conditions. Under these conditions, the producers of construction chemicals must provide certified cutting-edge technologies, including pre-bagged mortars for bolting, light weighted products with fast development of mechanical properties, waterproofing systems able to contrast and manage water inflows, in combination with solutions to refurbish concrete even with heavy thicknesses.
It is clear that a strict relationship between designer – construction company – chemical producer is mandatory to fine-tune innovative solutions that can benefit the development and finalization of all phases of a complex system.
