Institutional bulk sourcing profile for Drainage Aggregates, structured around certified specifications, project tonnage and GCC delivery requirements.
Technical & chemical specifications
Procurement specification grid
The values below are procurement reference points. The signed specification, producer certificate and approved laboratory results govern each order.
| Parameter | Specification / Commercial Basis |
|---|---|
| Material Class | Free-draining aggregate |
| Gradation / Weight Range | Commonly 10–20, 20–40 or project drainage grading |
| Reference Standards | EN 13242; ASTM C33 where applicable; drainage design specification |
| Specific Gravity | 2.55–3.00 source-specific |
| Water Absorption | Low absorption / durable rock preferred; project limit governs |
| Soundness / Durability | ASTM C88 / EN 1367-2 where specified |
| Port Logistics / Quarry Capacity | Confirmed against nominated quarry, crusher, trucking fleet and port slot; monthly tonnage stated in firm project offer. |
| Delivery Basis | Ex-quarry / delivered site / FOB / CFR / CIF as applicable to material, route and project logistics. |
Industrial & engineering applications
Application context for institutional procurement
Drainage Aggregates is used in heavy civil and marine procurement where subsoil drainage, French drains, retaining-wall drainage, permeable layers and infrastructure drainage systems. Institutional buyers should define the material class, gradation or weight range, geological source, density or specific-gravity requirement, water-absorption limit, durability testing, total project quantity and delivery sequence before issuing an RFQ. GCC infrastructure programmes frequently require engineered core rock for port breakwater protection, graded armourstone for wave loading, certified road-base aggregates for highways, or controlled fill and drainage materials for major civil platforms. AL BASAM coordinates sourcing against the project specification, nominated quarry and laboratory test regime, while also assessing loading method, trucking cycle, stockpile control, port handling and monthly supply capacity. For marine and quarry materials, commercial feasibility depends on both compliance and logistics: a technically suitable source must also meet vessel, berth, laycan and discharge requirements. Final acceptance is subject to approved samples, third-party or project laboratory reports, signed contractual specifications and the agreed inspection plan.
Quality compliance & documentation
Institutional transaction document package
The contracted document set is confirmed in the offer and may include the following, subject to product, origin, destination and buyer requirements:
- Independent third-party laboratory or inspection report from SGS, Bureau Veritas, Intertek, or another agreed inspector where contracted.
- Producer, quarry or factory test certificate identifying the supplied lot / batch and applicable specification.
- Factory Production Control (FPC) evidence and Safety Data Sheet (SDS/MSDS) where applicable to the material.
- Packing list, commercial invoice and certified Bill of Lading matching the contracted shipment.
- Legalized or certified Certificate of Origin when required by the buyer, bank, customs authority or destination market.
- Customs clearance / export manifests and project-specific inspection or conformity certificates where required.
