Yes. Iron Built supplies high-capacity boom pumps (36m to 52m reach) and stationary line pumps based on site height and accessibility. Pumping is especially recommended for high-rise buildings as it reduces manpower costs and speeds up concrete placement.
Quality is ensured at multiple stages:
• At site: Slump check for workability is performed at every batch.
• Test cylinders are cast on-site — one set cured for 28 days, another sent to BUET / authorized lab for independent PSI verification.
• At plant: Aggregates are tested by Los-Angeles Method, unit weight, specific gravity, and sand silt content checks are routinely performed.

Proper curing is essential for concrete to achieve its design strength. Water ponding or wet burlap curing should begin as soon as the concrete sets initially. Curing must continue uninterrupted for a minimum of 7 to 14 days to prevent premature cracking and strength loss.
