METHOD TO PREVENT PEELING OF ROOF MADE OF BITUMEN ROLL MATERIAL

摘要

FIELD: construction, particularly to repair roofing and waterproofing materials. ^ SUBSTANCE: method involves performing prior air or water evacuation from cavity by piercing air bubble and following rolling tool or similar tool usage; injecting chemical surfactant solution into the cavity in amount of 10-25% of removed air or water; introducing bitumen dispersion composition in cavity under pressure of 0.01-0.1 MPa, wherein the composition has viscosity of 14-32c on standard viscosimeter with 5 mm opening; creating bitumen layer in areas of roofing material peeling with the use of weight moving over roof surface; heating and compacting roofing coating; covering injection orifices with waterproofing material. ^ EFFECT: increased operational reliability. ^ 3 cl
