In brief
TCR Engineering runs a NABL ISO/IEC 17025:2017 accredited building material testing lab at Mahape, Navi Mumbai (certificate NABLT0726MH18640), for developers and contractors across India. Bricks, ceramic tiles, AAC blocks and cement are tested on the accredited scope, and tile adhesive, masonry mortar, glass, sanitaryware and aluminium formwork to their own IS, ISO and ASTM methods.
What Building-Materials Testing Covers
TCR tests building materials for construction quality assurance across structural and finishing works: bricks, ceramic and vitrified tiles, tile adhesives, AAC blocks, masonry mortar, cement, glass and glazing, sanitaryware, and aluminium formwork. Testing follows the governing IS, ISO, and ASTM methods, from compressive strength to thermal conductivity.
The governing-standards matrix below maps each material to its test anchor and standard.

| Ceramic and vitrified tiles | Water absorption, breaking strength, modulus of rupture, abrasion, dimensional | IS 13630, IS 15622 |
| Masonry mortar | Compressive strength, consistency, water retention | IS 2250 |
| Cement | Physical tests: fineness, setting time, soundness, compressive strength | IS 4031 Parts 1 to 15 |
| Concrete mix design | Mix proportioning and trial-mix verification | IS 10262, IS 456 |
| Ceramic sanitaryware and stoneware | Water absorption, crazing, load and functional tests | IS 2556 |
