Procurement & Technical FAQ
Frequently Asked Questions
Common engineering questions regarding compressive strengths, test procedures, delivery logistics, and bulk purchase terms.
Our Uni-Pavers achieve between 3000 to 7000 PSI (up to 48–50 MPa), well above BNBC standards. Solid Concrete Blocks test at 2000–2200 PSI, verified independently by BUET and MIST laboratory trials.
Yes. OptiBlocks is an approved vendor with test-certified supplies deployed in major Local Government Engineering Department (LGED) road infrastructure across Gazipur, Narsingdi, Sylhet, and Noakhali.
Non-fired automated concrete blocks consume zero agricultural topsoil and produce zero kiln emissions. They have uniform machine-finished dimensions, high compressive strength, lower water absorption (< 8%), and require 30% less mortar during masonry laying.
Our automated German-designed hydraulic compaction plant produces over 45,000 units daily. We coordinate full 7-ton and 15-ton truckload transport across all 64 districts in Bangladesh.
