Whether you're building a new home, renovating, or just looking for a way to retain rainwater on your property, you've probably come across the question: How many infiltration blocks do I actually need? The answer depends on several factors, but with the right infiltration system and a simple calculation, you can find out quickly and without complications.

What does the number of blocks needed depend on?

For a drainage system to be functional and effective, it must be custom designed. These factors play the biggest role:

• The size of the area from which rainwater is collected (e.g. roof, parking lot, paved area),

• Type of subsoil – clay soil seeps differently and sandy soil differently,

• Location and precipitation amount – Bratislava has different requirements, the High Tatras have different ones,

• The purpose of the system – only infiltration, or also retention and use of rainwater.
