Reference: drainage guidance
Reference- For surfaces that need drainage, 1–2% is often cited as a rough guideline.
- Recommended values vary by use (outdoor/indoor/flooring/standards).
- Always follow the relevant standards and specifications.
Често постављана питања
What is the difference between % and °?
% expresses rise/run as a percentage. ° expresses the angle. They represent the same slope in different formats.
How do I read 1:n?
It means a rise of 1 for every horizontal distance of n. Example: 1:40 is “go 40, rise 1.”
What is a negative slope?
A downhill slope. % and ° are signed; 1:n is shown as “Down 1:n.”
