METHOD FOR DAMP-PROOFING OF BELOW-GRADE BUILDING Russian patent published in 2008 - IPC E02D31/02 

FIELD: constructional engineering.

SUBSTANCE: invention refers to constructional engineering and can be used for building construction and upkeep. Method for damp-proofing of below-grade building includes levelling blanket laid on basement soil, formation of membrane system, formation of protective concrete layer, installation of reinforcing cage, concreting of footing and below-grade filler members. Membrane system is arranged by continuous laying of extended hoses made of polymeric fabrics and fastening them or, alternatively, overlapping at an angle to each other. Hose outflows are placed outside the footing. The footing and below-grade filler members concreted, damp-proof mixture is grouted through outflows to hose cavity pockets to produce impervious beds.

EFFECT: simplified below-grade construction procedure, improved reliability of groundwater protection of both horizontal and vertical footing elements, decreased work content as well as possibility to repair membrane system during building construction and upkeep.
