<\/p>\nWhen a flexible stone wall fails, three parties look at each other: the supplier who made the panel, the installer who bonded it, and the main contractor who owned the programme. The failure is real \u2014 a hollow field, a delaminating edge, a tone mismatch across a seam \u2014 but the cause is rarely self-evident, because a bonded finish is a chain of handoffs and every handoff can break it. Assigning that failure fairly is a technical exercise, not a shouting match, and the parties who come out best are the ones who kept evidence at each handoff. This guide walks through the common failure modes, which party\u2019s layer they belong to, and how to structure the project so the answer is knowable rather than negotiated.<\/p>\n
A tile failure is often self-evident: a cracked tile with a hard spot behind it points at the substrate. Flexible stone hides its causes better, for two reasons. The sheet is thin and conforming, so a substrate defect expresses itself as a bond failure \u2014 the symptom appears in the installer\u2019s layer while the cause sits in the builder\u2019s. And the face is printed, so a tonal complaint can be a batch issue, a lighting issue, or an expectation issue, and no single look at the wall settles which.<\/p>\n
The second reason is timing. The most expensive failures surface months after handover \u2014 hollows that develop as adhesive cures and seasons, edges that lift after the first winter \u2014 by which point the site is gone, the people have moved on, and the only remaining evidence is whatever was written down. That is why the honest answer to \u201cwho is liable\u201d is usually \u201cwhoever can prove their layer was sound\u201d \u2014 and why the evidence chain, not the contract\u2019s blame paragraph, decides most real cases.<\/p>\n
<\/p>\n
The supplier owns the material as manufactured and as documented. Failures that trace to that layer share a signature: the defect exists in the panel itself or in what the paperwork claimed about it.<\/p>\n
The common thread is documents. Every supplier-layer claim is argued with the retained sample, the batch COA, the pre-shipment photographs and the delivery packaging marks \u2014 the chain our container documents guide<\/a> describes keeping intact from factory to site.<\/p>\n The installer owns the method: what adhesive, applied how, onto what preparation. Their signature failures are method outcomes.<\/p>\n The main contractor owns the wall before the finish arrives and the building around it. Their signature failures are inherited by the finish.<\/p>\n Four practices turn an argument into an answer, and all four cost far less than one dispute. Retain a sample<\/strong> of the approved batch, sealed and dated, held by both buyer and supplier. Photograph the pre-shipment condition<\/strong> and the substrate at handover to the finish trade \u2014 two minutes at each handoff. Run the acceptance tests with records<\/strong>: lift-and-read at first fixing, tap-test map at completion, joint-width checks \u2014 the same evidence our submittal guide<\/a> formalises. Write the layer ownership into the contract<\/strong> before the job, so the argument is decided by a clause instead of a relationship.<\/p>\n Projects that do these four things rarely have liability disputes, because when a wall fails, the records point at a layer rather than at a party\u2019s wallet. Projects that skip them discover that the party with the best lawyer wins, which is a different system entirely.<\/p>\n A worked example shows the machinery. A hotel wall shows hollows at handover. The tap-test map marks them at scattered positions across the field. The lift-test photographs from first fixing show full transfer on the test sheets. The substrate handover record shows a straightedge pass. The adhesive was the approved product, mixed within its window. The hollows cluster where the wall was clad on the two hottest afternoons of the programme. The assignment is not rhetorical: open time was exceeded under site conditions nobody controlled \u2014 the remedy is removing and resetting the affected panels at the installer\u2019s cost, but with the main contractor sharing the programme risk it created, because the record shows where the pressure came from. That outcome is only reachable because every layer left evidence; without it, the same hollows would have been a flat argument between three parties about whose word counted.<\/p>\n Real walls often fail through a chain, not a single mistake \u2014 and honest assignment has to say so. Consider the pattern that recurs on exterior and wet-zone jobs: the substrate was handed over late and uneven, the installer bonded to it under programme pressure with a reduced coverage, and the supplier\u2019s batch arrived with a COA that matched the sample but no pre-shipment photographs. When the field hollows after the first winter, each layer contributed and each defence is partly true. The substrate was out of tolerance; the coverage should never have been reduced to keep the date; the paperwork alone could not prove what shipped.<\/p>\n The lesson is not that blame is impossible but that it compounds: fix any one link \u2014 a substrate rejection, a schedule slip, a pre-shipment photo set \u2014 and the failure does not happen. Contracts that allocate the failure wholly to the party holding the weakest evidence produce the worst outcomes on exactly these chains, because the weakest-evidence party is usually the one who trusted the others. The chain, not the tile, is the unit of failure, and the records at each handoff are what let it be taken apart honestly.<\/p>\n Reconstruct what can be reconstructed: adhesive batch from site stores, photographs from any stage, packaging marks from offcuts. Then agree a forensic opening \u2014 lift one or two affected panels and read the back. The adhesive pattern on the back usually tells the story: full transfer with crumbled substrate points upstream, sparse ridges point at method. It is weaker than contemporaneous records but it is evidence.<\/p>\n Almost never. Material warranties are conditioned on the approved system, and an unapproved adhesive hands the supplier a complete defence. That is precisely why the method is contract paper, not a suggestion.<\/p>\n En r\u00e8gle g\u00e9n\u00e9rale, la partie qui all\u00e8gue un d\u00e9faut prend \u00e0 sa charge l\u2019ouverture et la partie constatant le probl\u00e8me prend en charge la r\u00e9paration \u2014 \u00e0 convenir \u00e0 l\u2019avance dans la mesure du possible.
