ᐅ Is it absolutely necessary to connect a doormat drainage system to the building's drainage?

Hello everyone,

We are planning to install a recessed doormat just outside the front door. It will be placed under a 1.25-meter (4 feet) deep canopy and on a block step. Does it necessarily have to be connected to the drainage system, or would a stainless steel tray underneath that is cleaned regularly be sufficient?

I would appreciate any tips and experiences...

A 10 cm (4 inches) DN 110 KG pipe stub draining into a small gravel bed is completely sufficient. Those from Aco already have the recess for a connection anyway.

We have an Aco trench drain as a scraper, also installed under the porch roof and one step higher than the yard. The drain is not connected—where should large amounts of water come from when there is a roof above? Sand and dirt need to be vacuumed out once or twice a year, and that’s it.

Why should it?

We have nothing connected. Never had any problems!

Do you also have a scraper installed in your house?
Could you possibly share one or two photos...?

We are now planning to include this as well but are unsure whether it should be embedded in the screed or installed as a slim frame with the tiles.
