METHOD FOR DEVELOPING ANTIFILTRATION COATING Russian patent published in 2013 - IPC E02B3/16 E02B3/12 E02D17/20 

FIELD: construction.

SUBSTANCE: method includes arrangement of antifiltration elements from flexible sheets 5 of a spent polymer material on a structure slope 1. Antifiltration elements are fabricated from recycled car tyres in the form of flexible sheets by means of their processing into rubber crumb of fraction from 1.0 to 3.0 mm and its mangling in the form of sheets of specified size. Flexible sheets 5 are laid onto the bottom 2 and slopes 1 of the canal or the water reservoir along the entire perimeter with glueing of seams and fixation of sheets for stability of the coating onto the slopes with metal pins 3 and in the upper part at the ledge 4 of the structure edge. Flexible sheets for convenience of transportation and arrangement are made with the following size: thickness - 1.0-2.0 cm, width - 1.0-1.5 m, length - 5.0-10.0 m, and rolled into rolls with the diameter of up to 0.5 m and weight of up to 500 kg. Application of flexible sheets from spent tyres due to their considerable thickness and high resistance to damage excludes the necessity to arrange protective coatings.

EFFECT: antifiltration coating has high repairability, and high flexibility of a coating provides for reliability of its operation under conditions of possible base deformations.
