Know if your building is actually strong
A fresh paint job hides a lot. A building strength test is an X-ray for your concrete without breaking anything open (NDT — non-destructive testing). It tells you what's inside columns and slabs before you buy, retrofit, or ignore a crack.
Don't buy a Guwahati flat on looks alone
Families buy resale flats in Beltola, Six Mile, and Zoo Road based on location and paint. They don't know the bedroom column is hollow inside. They find out after the first monsoon leak — or after a tremor. A half-day test costs a fraction of the down payment.
Services
Ultrasound of concrete (UPV)
Sound waves through concrete — like an ultrasound. Weak, hollow, or cracked zones show up on the reading (ultrasonic pulse velocity).
When: You need to know what's inside columns, slabs, and load-bearing walls — before buying or before strengthening.
Risk: Hollow concrete can look perfect from outside. This test finds the voids before they become collapse points.
Surface hardness test (rebound hammer)
A spring-loaded device measures how hard the concrete surface is — a quick clue to compressive strength.
When: Screening many columns and slabs on a pre-purchase visit.
Risk: Soft concrete means poor mix or age. It will not carry earthquake load as designed.
Crack mapping & risk report
We measure, photograph, and classify every crack — structural vs cosmetic — in a report you can read.
When: After tremors, when buying, or when several cracks appear across the flat.
Risk: Not all cracks are equal. Without mapping you either panic or ignore something dangerous.
Pre-purchase building report
Full strength assessment before you pay a deposit — clear pass/fail on each structural element.
When: Before signing any resale flat or independent house in Guwahati.
Risk: Banks check paperwork, not concrete. You're the one living there when something fails.
When to get a strength test
- Before you buy a resale flat or old house
- Before you spend on strengthening (retrofitting) — so the repair matches the actual weakness
- After a tremor, or when new cracks appear
- Buildings 10+ years old, especially pre-2010 RCC
- Every 3–5 years on older occupied buildings — not a one-time stamp
What this is not
- Not a substitute for repair — a test finds the problem; strengthening or waterproofing fixes it
- Not a paperwork stamp for a builder or a new construction project
- Not something you do instead of calling us about a leaking tin roof — we don't coat sheet roofs
What you'll receive
A clear report in plain language — not a 50-page engineering document. Which columns passed, which need attention, and what it will cost to fix. You decide: buy, negotiate, walk away, or repair.
Concrete weakens with age
Water, rust, and thinning cover reduce strength over decades — often with no warning until concrete flakes or a tremor widens a crack. The hammer and ultrasound tests show what paint hides. A building that 'looks fine' at 20 years may have columns below design strength.
Other states already require audits
Maharashtra requires structural audits on certain old buildings. Delhi has pushed periodic safety checks. Assam has not mandated the same yet — owners who wait for the law often pay emergency prices after failure.
