    Abstract: An environmentally acceptable leak sealant comprising lava rock aggregate (scoria) for sealing leaks in dams, holding ponds or other water-containing structures. The aggregate is selected and graded for particle size and density. Particles of different sizes cooperate to engage walls of the leak and interlock with each other to form a seal within a leak opening. The particles must sink at a suitable rate, and become entrained in water flow through the leak. Beneficially larger particles have a generally higher sink rate than smaller particles, and so arrive first at the leak to staunch a major part of the flow; intermediate and smaller particles follow to form an effective seal. Applications include sealing sluice gates, stop logs at hydroelectric dams to reduce water wastage for increased electricity productivity, for maintenance requiring de-watering of the turbine; or for sealing leaks in cracks in bedrock or concrete structures associated with dams.

    Abstract translation: 一种环境可接受的泄漏密封剂，包括用于密封大坝泄漏，保持池塘或其他含水结构的熔岩岩石聚集体（污垢）。 选择和分级聚集体的粒度和密度。 不同尺寸的颗粒合作以接合泄漏壁并彼此互锁以在泄漏开口内形成密封。 颗粒必须以合适的速率下沉，并被夹带在通过泄漏的水流中。 有利地，较大的颗粒通常具有比较小的颗粒更高的吸收速率，因此首先到达泄漏处以使流体的主要部分保持稳定; 中间和较小的颗粒随之形成有效的密封。 应用包括密封闸门，在水力发电大坝停止原木，以减少水浪费，提高电力生产率，维护需要涡轮机的脱水; 或用于密封与大坝相关的基岩或混凝土结构的裂缝中的泄漏。
