Aluminosis is Barcelona's hidden structural defect: high-alumina cement (HAC) used in concrete floor beams between 1950 and 1975. We test for it with a lab analysis and a signed report — fixed price, guaranteed deadline.

Thousands of Barcelona buildings raised between 1950 and 1975 used precast concrete beams made with high-alumina cement — the same material behind the UK's HAC scare of the 1970s. Over decades, with humidity, the cement converts chemically and loses strength. You cannot see it during a viewing, and the building year alone only tells you the risk.
The only reliable answer is physical: extract a small core from a beam and analyse it in a certified laboratory. That is exactly what this test does — and in 2 out of 3 of our tests, the answer is reassuring: no aluminous cement found.
1,000+ tests done. Your ceiling won't surprise us.
A surveyor visits within 48 h, locates the beam nerve with detection tools and extracts an undisturbed sample without damaging the structure.
On-site chemical checks plus certified laboratory analysis determine the cement type and its degree of conversion.
You receive the interpreted result in a report signed by a licensed technical architect — valid for purchases, banks and homeowner communities.
Core sample, certified lab analysis and a signed surveyor's report. No hidden extras — travel within metropolitan Barcelona included.
If the building is from 1950–1975 and there is no recent structural documentation, yes — it is the single most important check in that age range, and the one a standard survey does not include. We can combine it with a full pre-purchase survey.
A positive is not a condemned building: it means the degree and location are now known. The report states what follows — monitoring, further sampling or reinforcement — and it becomes your negotiation evidence on price.
Yes — WhatsApp, visits and explanations in English. The signed report follows the Spanish technical standard (that is what banks and notaries expect), and we walk you through it.
Visit within 48 h, signed report within 7 days — guaranteed in writing. Urgent service in 48–72 h if your deadline is tight.
Yes, and that is the right moment. We only need the seller's permission and access; the visit takes about an hour and leaves a small patch that we make good. Tell us your deadline and we prioritise the report.
