The concrete fuel storage tanks required a robust waterproofing solution capable of withstanding continuous exposure to hydrocarbons and preventing leakage into the surrounding environment. To ensure long-term durability and impermeability, Xypex crystalline waterproofing was integrated into the concrete structure. Products Used: Xypex Admix C-1000 NF, Xypex Concentrate Scope: Concrete fuel storage tanks and associated containment structures Details: Xypex Admix C-1000 NF was incorporated during batching to provide integral waterproofing throughout the concrete matrix. Xypex Concentrate was applied to critical areas, joints, and surfaces to enhance protection against hydrocarbon penetration and ensure complete watertightness. The crystalline technology actively seals pores and micro-cracks, improving resistance to fuel exposure and preventing leakage. Outcome: Reliable, long-term containment of fuel with enhanced resistance to hydrocarbon ingress, reduced environmental risk, and minimized maintenance requirements for critical infrastructure.
