Decision boundary
This guide decides: which fill, filter, subgrade, placement and responsibility inputs must be coordinated.
This guide does not decide: stone grading, filter class, geotextile selection, bearing preparation, hydraulic adequacy or installation approval.
Make mesh-to-fill compatibility explicit.
Record the approved grading, durability, shape, density or appearance requirements and the relationship to the mesh opening and unit depth. Confirm whether fill is local, buyer-supplied or part of another contract.
Define the filter function and interface.
State whether the project requires soil retention, drainage separation, filtration or another function. Provide subgrade, water, overlap, transition and adjoining-work information to the responsible designer; do not select a geotextile from a generic product label.
Control placement and visible-face requirements.
Describe access, lifting, machine or hand placement limits, face quality, bracing/formwork responsibility, overfill or settlement allowance policy and inspection hold points. These inputs affect the commercial scope but do not become site instructions on this page.
Placement reference · external video
See why stone shape and placement method belong in the brief.
This 1-minute 16-second supplier demonstration shows hand placement of interlocking stone inside a gabion basket. It adds a visual check to the written schedule without turning one supplier's method into a project instruction.
What to watch for
- Face stones are deliberately oriented rather than tipped in at random.
- Irregular interlocking pieces create a different placement task from rounded or undersized fill.
- Visible voids and the final top level can be inspected before the lid is closed.
Transferable lesson: the enquiry should state the approved stone grading and durability, the allowed placement method, visible-face requirement, void-control expectation, access limits and the inspection point before closure. Those inputs affect labour and scope even when the basket specification is unchanged.
Source boundary: the video is published by WireFence and demonstrates that supplier's hand-filling approach. It is not a XIEHENG installation instruction and does not approve stone grading, structural behaviour, hydraulic performance, geotextile selection, compaction or the completed work.
Decision ledger
Use the actual condition to route the next review. This ledger is not a design table, rating or installation instruction.
Project-input schedule
Issue the same controlled inputs to every supplier. Keep unknowns open with an owner and due date.
What a usable supplier response returns
The response identifies the exact offered mesh or cage, unit and component quantities, material and coating basis, drawings, packing and document register. It separates confirmations from assumptions, options, exclusions and deviations. Civil, structural, hydraulic, geotechnical and rockfall decisions remain with their responsible project authorities.
Questions to close
- Who approves fill grading and durability?
- How is escape through the mesh prevented?
- What function must the filter perform?
- Who selects the geotextile and transitions?
- Which placement and inspection records are required?
