Name the example being shown.
The opening was narrowed to a liquid membrane over screed. That small wording change helps the viewer understand the scope of the drawing rather than treating it as every possible bathroom-floor arrangement.
SELECTED WORK / CERTIFIED WATERPROOFING
A short visual explanation of why the opportunity to inspect a detail changes as work covers it. Created by Kevin for his own waterproofing practice, before Motren’s launch.
This is an own-practice work sample, not a third-party client commission. The drawing illustrates one liquid-membrane-over-screed example; it is not a construction drawing or a universal installation sequence.
The production record connects the wording to its source material and maps the explanation into seven beats. It also records revisions to the opening, qualifications and reading time. The artifacts below show how the explanation became more specific.
Who checks the waterproofing before the tiles go on?
A section view builds up in stages. Captions explain the change, while the viewpoint stays consistent.


The opening was narrowed to a liquid membrane over screed. That small wording change helps the viewer understand the scope of the drawing rather than treating it as every possible bathroom-floor arrangement.
The wall, floor and drain remain a reference as the drawing builds. The viewer can follow the changing layer without first working out a new camera angle.
The final review brought the inspection-role boxes on earlier, enlarged their qualifications and held the complete list longer. The explanation needed to remain readable on a phone, including the conditions attached to each role.
The production record includes source checking, a still-frame review and a final-film review. The example wording, conditional statements and screen timing were revised before the final cut.
The finished piece is a 41-second portrait MP4 with on-screen captions and sound effects. This case page adds a poster, an optional caption track and a text explanation so the work can be explored in more than one way.
The result shown here is the completed and published explanation. No sales, lead or inspection-outcome uplift is claimed.
The film uses one example of a bathroom floor to show how a layered drawing can explain what becomes concealed. The surface falls towards the drain; the illustrated liquid membrane sits over the screed; a water test is presented conditionally; and the finish covers the work.
It then introduces people who may see the work at the relevant stage, retaining the qualifications attached to their roles. The closing point is to arrange the relevant check before the detail is covered.
A product link, a drawing or a few lines about the question is enough to start. Tell me who needs to understand it and where it will be used.
