The constructions with fluid retention and storage in general, between which the water holds a significant weight, are permanently exposed of physical and mechanical actions of deposited agent, with the continuous manifestation of the exfiltration tendency, herby the requirement of performance at tightness becomes essential. If the constructions that fulfill this role are realized of reinforced concrete, the tightness at fluid in general and at water in particular of the elements which compose the storage space is insured in a significant proportion by the waterproofing qualities of the structural concrete put in place. When the process of waterproofing concrete is clean and environmentally friendly and leads to improvement of initial physical-mechanical characteristics, represents an essential element in the combined approach of the performance requirements regarding the tightness and resistance condition. In this paper is presented a research study concerning the positive influence of waterproofing additive “Penetron” introduced into the fresh concrete mass used to realization of structural elements, with the role of storage and treatment of waste water, to mechanical characteristics of concrete after hardening.
