FIELD: construction.
SUBSTANCE: method for erection of batter drainage of biopositive design includes multi-layer filter. Filter is made of flexibly joined biopositive mats made of meshy shells and draining filler, which is made of layerwise folded rows of light fascines inside shells, and lower rows of fascines are laid normally in direction of filtration flow, and upper rows are laid along its direction, the mats themselves are pierced with metal wire in some areas.
EFFECT: improved efficiency and biopositive property of design, reliability of design, reduced material intensity.
