A key reality for the construction sector
In September 2025, the National Association of Ceramic and Building Materials Distributors (Andimac) has published a report that warns about the aging of the residential stock in Spain. According to its data, by 2030, more than 10 million homes will be between 60 and 90 years old.
Energy efficiency and habitability at risk
The study highlights that 80% of residential buildings in Spain have a low energy rating (E, F or G). This implies urgent needs in:
- Thermal and acoustic insulation.
- High energy consumption.
- Comfort and structural safety.
In addition, rehabilitation is progressing at an insufficient pace: in the last 10 years, some 275,000 homes have been renovated, compared to the target of 410,000 between 2021 and 2026 set in European plans.
Shortage of skilled labor
Another point highlighted by Andimac is the lack of professionals in the sector. Fifty-five percent of construction workers are over 45 years old, which reinforces the need to improve training in technical solutions such as high-performance adhesives, repair mortars and insulation systems.
Colcret solutions for rehabilitation
The scenario described above makes building renovation a strategic growth area for the sector. In this context, Colcret offers a range of products designed to meet these needs:
- High-performance cementitious adhesives(Colcret Flex, Flex Premium, Porcelánico Plus): ideal for the safe installation of ceramic tiles in facade and home renovations.
- Structural repair mortars (Colcret R series): designed to restore deteriorated concrete substrates in old buildings.
- SATE/ETICS systems with specific mortars: contribute to the improvement of energy efficiency and thermal insulation of buildings.
- Grouts (Colcret Junta Clasic and Junta Premium): to renovate ceramic finishes and guarantee durability in demanding environments.
An opportunity for the future
The combination of an aging residential stock, low energy efficiency and European sustainability objectives means that renovation will be one of the main drivers of construction in Spain in the coming years. Colcret is aligned with this need by providing technical solutions that reinforce durability, efficiency and safety in housing renovation and improvement projects.
