Engineering team and credentials.
Infraconcrete Construction Sdn Bhd is a CIDB G7 (highest grade) contractor with ISO 9001:2015. Our sister company Starwall Sdn Bhd holds the STRATA Geosystems appointment for Malaysia. Both companies operate under Panthera Group from Petaling Jaya, Selangor. The combined team includes registered engineers, project managers, geotechnical specialists, and field crews with cumulative experience on 100+ Malaysian geotechnical, slope, and geosynthetic projects.
Two companies, one accountability point.
| Company | Role | Why this matters to project owners |
|---|---|---|
| Infraconcrete Construction Sdn Bhd | CIDB G7 contractor for slope stabilization, MSE walls, geosynthetics installation, earthworks, and ground improvement | Single signature on the main contract. ISO 9001:2015 QA on every site. |
| Starwall Sdn Bhd | Appointed STRATA Geosystems Malaysia distributor (StrataGrid, StrataTex HSR, StrataWeb, StrataDrain, StrataBlock, StrataWall, StrataSlope, Sleeve-It) | Direct supply from STRATA, no broker mark-up. Factory warranty intact. |
| Panthera Group | Parent holding company. Owns Infraconcrete + Starwall plus other construction and engineering businesses. | Capital, governance, and group warranty stand behind both subsidiaries. |
This structure is the answer to the most common project-owner question on geosynthetics work: "If the material fails, who is responsible - supplier or installer?" Under our group model both are the same ownership. One root cause investigation, one remedy, no inter-party finger pointing.
