Anchors for Cracked Concrete: The Documents Buyers Should Request

Let the design requirement lead

Hilti’s guidance explains that assuming uncracked concrete requires justification over the anchor’s service life. A buyer should therefore obtain the stated design condition from the project’s responsible engineer rather than deciding it from the surface appearance of the concrete.

Check a product, not just a category

Manufacturer documentation identifies whether an anchor is covered for cracked or uncracked concrete. Hilti points users to its anchor documentation and the relevant assessment. The purchasing lesson is to verify the exact model, size and scope instead of accepting “suitable for concrete” as a complete answer.

Create a document request that can be answered

Attach the project requirement and ask the supplier to map the proposed product to it. Keep the proposed item reference consistent across the quotation, technical documents and sample labels. If the supplier cannot provide a requested document, record that gap before progressing to a commercial decision.

• Exact product model, size, material and proposed configuration.
• Applicable assessment or evaluation document, with identifier and revision.
• Pages or tables covering the required concrete condition and size.
• Installation instructions associated with the proposed product.
• Any stated limitations relevant to the project.
• Batch and product identification required for the delivered order.

Distinguish completeness from acceptance

A complete document folder is a good starting point, but someone still needs to review its applicability. Nominate the person responsible for technical acceptance and keep that decision with the purchasing record. Do not let a quotation deadline silently replace an unresolved technical review.

For example, a supplier may submit a document for a related product with a similar name. The buyer should ask for an explicit explanation of the connection rather than assuming the document covers everything in the supplier’s catalogue. A different diameter, material or model can be significant to the review.

The same check is needed when replacing an unavailable item. Keep the original requirement, the proposed alternative and the acceptance decision together, so the warehouse and installation team can see what was actually approved.

Keep marketing claims within the evidence

If you distribute anchors under your own label, establish which claims may appear on the product page and packaging before printing them. General quality-management information is useful company context, but it should not be presented as product-specific cracked-concrete evidence.

When contacting DURANCHOR, include the required assessment and project condition in the enquiry. Ask whether the exact proposed item has the necessary supporting documentation. This article is a purchasing checklist and makes no claim that a listed DURANCHOR product holds a particular approval.

Frequently asked questions

Can I identify uncracked concrete just by looking at it?

A visual observation does not establish the design assumption over the service life. Obtain the condition specified by the responsible engineer.

Does a company certificate cover every anchor it sells?

No. Ask for the product-specific documentation applicable to the exact item and requirement.
