What we do
Three pillars of structural assurance.
Aggregate Testing
Sieve analysis, specific gravity, absorption, soundness and deleterious materials per ASTM C33, C117, C127, C136.
Non-Destructive Testing
Rebound hammer, ultrasonic pulse velocity, cover meter and rebar locator surveys on in-situ structures.
Why Delta
Built for Caribbean construction realities.
Tropical climate, salt-laden air, hurricane-rated design loads — the materials going into your structure have to perform here, not just on paper. We test against the standards your engineers specify and the conditions your buildings actually face.
Independent & impartial
We don't sell concrete or aggregate. Our only product is the data.
ASTM-aligned procedures
Methods traceable to international standards your engineer of record trusts.
Island-to-island coverage
Caribbean-based crews ready to mobilize across the region. No flying in from Miami.
Fast, readable reports
Digital reports within 48 hours of break date. No mystery jargon.
