Seattle's eleven concrete‐paved reservoirs, constructed during the last 60 years, vary in capacity from 5 to 68 mil gal. The use of portland cement concrete for lining ground‐level reservoirs results in maximum, useful reservoir life with minimum maintenance. Adequate reinforcement of the slabs to control cracking due to changing conditions of temperature and moisture and proper sealing of the construction and contraction joints to prevent leakage at the joints are the keys to a watertight reservoir. This paper discusses an effective method of sealing joints that has been adopted by the Seattle engineering department. The article discusses two essential elements in an effective joint, a waterstop cast in the slab and a joint sealer at the surface. Construction of the joint is discussed, along with two types of sealer, a hot‐poured rubber‐asphalt mixture and a cold‐applied polysulfide rubber compound.
