Innovative Treatment of Facades and Roofs for Périgord Habitat: a Foundational Multi-Year Project  

Project Context  

Périgord Habitat launched its first multi-year market for the maintenance of facades and rooftops in 2023 and chose to trust FlyRenov to carry out part of this work. In the first year, work on 15 sites spread between Bergerac and Périgueux was addressed. This project represented a genuine challenge, both in terms of its scale and the scheduling requirements that imposed the treatment of over 40,000 m² in 4 months. The summer drought made the work even more complex with the necessity to use only water pumped from certain rivers identified by the department as not being under water stress.  The first year marked a foundational milestone in the evolution of Flyrenov, with the arrival of the first intervention teams and the confirmation of the effectiveness of bio-based and biodegradable products. Since then, we have been conducting interventions each year on various sites of Périgord Habitat to ensure the general condition of the real estate portfolio.  

Organisation and Operational Process  

Preliminary visits to establish quotes to assist Périgord Habitat in selecting works to be carried out.  

Every year begins with a preliminary inspection of all sites, carried out by Maxime, the dedicated drone pilot team leader for interventions in the Périgord. This visit allows for the assessment of constraints, validation of products to be used, and identification of sensitive areas (plants, vegetable gardens, animals). Eva, the project manager in Nouvelle Aquitaine then prepares the quotes in agreement with Maxime and participates in planning the interventions. Organisation and anticipation are essential as several projects are often conducted in parallel.  

On-Site Coordination and Team Briefing  

On the day of the intervention, Maxime delivers precise instructions to all the workers on site and informs all residents of the start of the works: 

• Preparation of products 

• Securing the perimeter with barriers or tape

• Monitoring drone flight zones 

• Monitoring application stages  

The co-pilot plays a crucial role: they assist the drone pilots with the refuelling and dilution of treatment products, the protection of vegetation, and vigilance around the drone.  

Treatment Methods  

Facade Treatment Steps  

• Application of anti-static degreaser before washing

• High-pressure rinsing of heavily contaminated surfaces 

• Spraying of curative and preventive anti-fungal agents  

We have chosen to use curative and preventive anti-fungal products that do not require rinsing and effectively act on moss, lichens, and fungi. It activates with moisture and its effects can last up to 5 years.  

Roof Treatment: a 100% Secure Approach 

• Manual brushing beforehand if necessary 

• Spraying by drone   

The use of drones avoids costly scaffolding, limits the use of platforms, and ensures maximum safety for the teams.  

Testimonials and Anecdotes  

Particular Attention to the Environment 

Anecdote: In Saint-Pierre-d’Eyraud, a resident had a dog, a vegetable garden, and many plants. The team covered her entire garden by hand to preserve everything. The resident, very satisfied, praised the thoroughness and care taken.  

The Water Challenge in Coulounieix  Anecdote: In the middle of summer 2023, the Coulounieix site faced a strict water restriction due to the drought. To fill the tanks, the team had to draw from the river below, making multiple trips due to the elevated site configuration. A demanding logistics challenge, but one that was appreciated by Périgord Habitat as the cleaning objectives were thus met 

A Structuring Project for Flyrenov  

Technological Innovation: the Drone at the Heart of the Process  

The use of drones allows for a significant reduction in costs and treatment times. It is also an essential element to ensure maximum safety.   

Successful Initial Major Projects  

This contract with Périgord Habitat represents a turning point for Flyrenov, marking the realization of the first large-scale drone projects. They also provide valuable feedback as we continue to track the evolution of the support which remains spotless each year. 

Conclusion  

The partnership with Périgord Habitat perfectly illustrates Flyrenov's philosophy: to combine innovation, ecology, and safety to renovate buildings sustainably while optimizing costs.
