Abstract

Anyhow renovation of the surfaces of building materials and structures without thorough disposal of biological material has not been proven in the past. The main topic of the paper is to find out the functionality of the new technology in terms of survival and development of biocorrosion in structures. The main focus of the thesis is verification the treatment of moisture composite "Double ETICS", the possible growth of microorganisms and the subsequent degradation of components. The aim of research is to propose a methodology for the verification of humidity and temperature conditions in the composite construction and development of microorganisms after application of alternative technology of preparation of the substrate under the technology "Double ETICS".

Highlights

External thermal insulation composite systems (ETICS) are often used throughout the world at present
It is important to investigate the causes of algae and fungi growth to understand the hygrothermal behaviour of facades covered by the ETICS
It is assumed that the results demonstrate the temperature and humidity conditions appropriate for the development of microorganisms in the set

Summary

Introduction

External thermal insulation composite systems (ETICS) are often used throughout the world at present. Despite their thermal advantages, low cost and effortless of application, undesirable problems causing microbiological growth and damage to the cladding may appear on this system. It is important to investigate the causes of algae and fungi growth to understand the hygrothermal behaviour of facades covered by the ETICS. The extermination and long-term prevention of surface colonization require immediate operational interventions and efficient technologies. In this context, knowledge of possible interventions has been gathered and verified. To remove microorganisms in contact thermal insulation systems in practice there are used to two basic technologies with different lifespan, financial and technical demands - conservative and radical
