This chart shows the efficiency of Smart Drain in sand and clay. The theoretical flow
rate is what you would get with gravity drainage. The measured flow rate shows Smart Drain's
actual performance in laboratory tests. This shows how Smart Drain is faster and more efficient
than traditional gravity drainage.

PHYSICAL PROPERTIES
|
|
Smart Drain is also very compression resistant. Its low profile design, with the arched
support of the micro channels, makes it one of the strongest drainage materials around.
