Site Inspector

It lets you check the size and shape of the sealant fillet you have run into a junction, and confirm the bond breaker is sitting where it should before the membrane goes over it. This matters because internal corners, changes of plane and movement joints are where wet area membranes are most likely to fail. The Site Inspector Trinity Reach Blades Fillet/Bond breaker measurement tool is built for that check. Australian wet area waterproofing is generally carried out with reference to standards such as AS 3740, so a physical gauge takes the guesswork out of the conversation.

It is a combination gauge that brings several routine site checks together in one pocket tool, so you are not carrying separate gauges for fillet work, gap measurement and marking out. It suits applicators and inspectors who move between jobs and want a single tool that covers the usual verification checks. For the exact functions on the version currently stocked, see the product page and its technical data sheet.

A taper gauge measures the width of a gap, joint or crack by sliding the tapered blade in until it stops, which gives you a readable width instead of a guess. Inspectors use them for crack width on concrete and render, and waterproofers use them for checking joints and penetrations before detailing. The 3 IN 1 TAPER GAUGE Inspection Tool is a combination tool, so the taper blade is one of several measurement functions on the same body.

Both, and that is the point of the range. Applicators use them during install to confirm fillets, bond breakers and joint widths are correct before the membrane goes down, which is far cheaper than discovering a problem after tiling. Building inspectors and supervisors use the same gauges to verify the work at handover and to record what was actually measured. Because the tools are small, most trades end up leaving one permanently in the pouch.

Experience tells you what looks right, but a gauge tells you what is right, and that difference matters the moment a job is inspected or a defect is disputed. Photographing a detail against a gauge gives you a record that the work was formed correctly on the day, not a recollection months later. On a trade where rectification means pulling up tiles, that is cheap protection.

Wipe them down before sealant or membrane cures on the blades, because dried product on a measuring face will throw the reading out. While the material is still wet, a rag and a suitable solvent is usually all it takes. Store them flat in a pouch rather than loose in the bottom of a bucket so the measuring edges stay true.

The Site Inspector range stocked here, including the Trinity Reach Blades fillet and bond breaker gauge, the Predator Guage 5 in 1 Tool and the 3 IN 1 TAPER GAUGE Inspection Tool, can be ordered from this collection page and shipped Australia wide. Because they are small hand tools, most trade customers add them to a membrane, primer or sealant order rather than freighting them on their own. If you are unsure which gauge suits the work you do, call our team and we will point you at the right one.
