A recognised expert
Aware that traditional methods of treating nuisances and material damage are very often costly and restrictive, founder Jacques COUEFFE made a decision: to leverage his expertise in adhesive films to develop innovative and elegant solutions to these challenges.
Our ambition? To ensure comfort, safety, and aesthetics in urban spaces — a daily challenge that requires balancing environmental responsibility, budget control, and public satisfaction. Thanks to the expertise and determination of our team, GSDI has established itself as a recognised expert in surface treatment.
Our mission? To preserve, restore, and protect the environment, and, in doing so, contribute to improving everyone's quality of life.
Europe's largest installation workforce
GSDI has the largest adhesive film installation team in Europe, with 180 full-time technicians, all trained through a comprehensive programme dedicated to this profession at GSDI Group's own specialised training centre, created to meet the demands of a highly professional market.
From graffiti and surface damage to enhancing protection, decoration, redesign, glare reduction, ambient heat control, scratches or stains, we deliver tailored solutions for every need, both indoors and outdoors.
Our reach extends across Europe and Africa, supporting public and private clients in rail and public transportation, construction — including sensitive sites like embassies, banks, museums, and jewelry stores — and commercial real estate and retail.
Overnight, before the day begins
We understand that time matters. Our teams can transform a shopfront, protect interiors from UV or intrusion, or renovate furniture, all overnight, ready before the next day begins.
Thanks to our in-house printing department and production facilities, we're able to respond fast and deliver fully customised solutions with complete control over quality and deadlines.
