No blanket equivalence
Every guide distinguishes a possible alternative from an approved equivalent. The specification, current product data and project conditions remain controlling.
Specified-product review · geosynthetics
Review the product. Preserve the engineering function.
Named products are common in civil and mining specifications. These guides help contractors, designers and asset owners assess a responsible alternative without assuming that similar catalogue language means equivalent performance.
Product-family guides
Start with the application—not a logo.
Each guide names the products people actually search for, then sets out the technical checks needed before any substitution, alternative or value-engineering proposal should be accepted.

No affiliation implied
Third-party names identify products that may appear in searches or specifications. They do not imply endorsement, affiliation or supply unless the page expressly says so.
Evidence before price
A lower unit rate only creates value when the product, design assumptions, construction pathway and acceptance evidence survive scrutiny.
What to send
Turn a named-product clause into a quick, practical review.
01Specification and drawingsInclude the named product, grade, clauses, detail and current revisions.
02Ground, liquid or process conditionsProvide the inputs that control the product family—not just the bill-of-quantities description.
03Programme and quantityState approval timing, required-to-site date, dimensions, area or volume.
04Required review levelTender option, value engineering, formal submission, supply quotation or technical gap check.
Identification and trademark notice
Third-party product and company names are used only to identify specification terminology and facilitate technical comparison. All trademarks remain the property of their respective owners. Kontain is not claiming that its products are identical to, approved by, or affiliated with those manufacturers. Suitability and acceptance remain project-specific.
