Saumalaakso – Use of durable materials in sealing by Eetu Helminen
In general the impact of resealing in due time is greater than the impact of this single planet act. If resealing is done in time and that reduces the need to use pristine concrete to renovate facades the impact can be substantial. However the sealing materials are only a small portion of the environmental footprint of a building, therefore the act of renovating rather the renewing is the clue to this act.
The drive to use environmentally friendly materials is admirable and should be shared throughout the whole construction industry. Therefore being a frontrunner and showing example to the industry and customers is important.
