BIFORIUM / GUIDE
LOW THRESHOLDS AND WATER
A low threshold does not remove water. It reduces available height, making every millimetre between floor finish, track, exterior paving and waterproofing important.
How to coordinate a low or barrier-free slider threshold with falls, drainage, membranes, terrace build-up and overflow strategy.
Set levels before screed
System height, exterior fall and terrace finish need one coordinated section.
Drainage needs an outlet
A channel without a reliable discharge becomes a reservoir beside the frame.
Membranes remain continuous
Corners, supports, anchors and transitions to the façade require particular attention.
