Waterstop stock.
Measure each continuous supplied waterstop path and list all approved splice locations.
Read the right quantitative data
Stock length and the explicitly supplied loss at each permitted splice.
Check this ordering assumption
Total run length alone cannot show whether an unspliced continuous section fits.
Waterstop profile, location and splice method are outside the count.
A worked quantity method
This illustrative set of supplied inputs demonstrates Waterstop Stock and Splice Quantity Calculator. Replace the example measurements and product figures with your own before ordering.
| Supplied input | Metric display | US display |
|---|---|---|
| Selected stock length | 5 m | 16.4 ft |
| Specified overlap consumed by each splice | 0.2 m | 0.66 ft |
| Waterstop run 1: Measured run length | 10 m | 32.81 ft |
| Waterstop run 1: Identical runs | 2 | 2 |
Waterstop stock lengths: 6 lengths
- Measured runs
- 20 m
- Specified splices
- 4
- Length consumed in overlaps
- 0.8 m
Every run retains separate splice rounding. This arithmetic does not choose a waterstop type, splice method or watertight detail.

Turn the estimate into an order
- Confirm that all quantities use the same measured basis and the selected product's current data.
- Keep different products, finishes and handed variants in separate purchase lines.
- Review exact demand and whole-pack purchase quantities before entering your quoted prices.
- Record compatible stock already on hand, then save the remaining order in your browser project.
