Specifying GCLs requires more than stating a blanket weight. sodium bentonite clay liners should be described by their construction, bentonite information and required barrier properties. The purchaser needs to know what each reported mass represents before comparing it with another product's headline figure.

An offer for 5500gsm bentonite blankets should make clear whether its designation refers to bentonite content or the whole composite. This guide focuses on the material schedule and compatibility evidence that turn an approximate product request into a specification the delivery team can check.

Separate mass descriptions

Ask whether a stated value refers to dry bentonite, total product mass or another defined measurement. Record the test basis and acceptance criteria. Two figures with different meanings cannot establish equivalence. Keep bentonite quantity and carrier construction as separate entries so the composition of the offered liner remains understandable.

Identify the carrier layers

State the fabric types and reinforcement or bonding method required by the project. Request a cross-section of the actual product. Carrier construction can influence handling and the arrangement of the barrier component, so it should not be hidden behind a general GCL name. Confirm orientation guidance where the selected product requires it.

Request compatibility information

Supply the relevant fluid description and project conditions for review. A product intended as a water barrier is not automatically suitable for every liquid. Ask what assessment supports the proposed use and identify limitations in the available evidence. Keep technical acceptance linked to the supplied model and surrounding construction.

Include roll and joint details

Record roll dimensions, packaging, installation joints and any specified supplemental material. Quantities should include the accepted connection details rather than just the footprint. Ask how storage and handling protect the product before installation, especially where weather exposure or a delayed cover sequence may affect the site method.

Make the submission measurable

Send Suneco New Materials the construction schedule, required properties, mass definitions and application section. Ask for model-specific data and note every proposed alternative. The final order should allow inspectors to match labels and documents to a defined liner, reducing ambiguity about what the stated bentonite content actually includes.
