walk in and concrete

[Dave Maxwell]

Ever hear of puting door sill in the concrete? Morton says they design it that way

In or on?
Most I have seen are sitting on top of a smooth slab.
They are not set into any kind indentation.

The plate will be one inch into the Crete according to them

Overhead doors, right?

Shop I once worked at had a Morton, concrete for all four overhead doors was 1 - 1 1/2" inches below interior slab. Kind of a sill/apron type of arrangement. It kept any chance of standing water or ice/snow from creeping inside under a maybe not so perfect gasket seal.
I've also seen this arrangement on some residential applications. It works.

I've seen it done, and I don't like the idea. What do you do when you need to install a new door frame in 40 years?

 

[Dave Maxwell]

Walk in. That's what I told the salesman. What if I need to replace

 

[willymakeit]

I have poured the entrance slab lower and let the door set on that, but wouldnt like the door setting in basicaly a trench.

 

[camarotoolman]

common here. Not in a trench, drive way is always lower.

They say cement pours up to top of aluminum. Use expansion joints underneath and plastic on face to aid in future removal
