METHOD TO CLEAR DEFECTS IN DAMS OF HOMOGENEOUS SOIL Russian patent published in 2011 - IPC E02B3/16 

FIELD: construction.

SUBSTANCE: method includes digging trenches with depth exceeding crack or filtration path height, filling trenches with a soil mixture from a soil cement with an additive, a layer-wise compaction, arrangement of a protective coating along the upper slope and ridge with the thickness of not less than the freezing depth. The additive used to increase strength and frost resistance is a mixture of ash and siftings in the amount accordingly of 4-6% and 20-35% of the soil mix weight.

EFFECT: improved efficiency of hydraulic insulation due to elimination of filtration water leakage through dams body, protection of a dam body in most dangerous areas against harmful effect of earth-moving animals, and a better heat insulation effect at lower thickness of a protective coating.
