I have a door that at the bottom of my walk out basement.  During a very heavy downpour the slab out side the door was flodded and the water came above the threshhold of the door.  Causing a little mess.

 

I want to raise the door and install a waterproof curb then install ramps to get object in and out of the door.

The header is just a bunch of 2x6's laid on the 1 1/2 T edge and there are like 20 of them going up the top sill. 

I can just take out two then raise the door 3" and that shold be fine.

 

Does anyone have any idea how to create a curb that will not leak?

 

Just my opinion, but I think it would be better to create a drain in the slab.

Putting a drain in the slab would be my last option as I have to break up the slab to install the drain the repour it. 

Also the slab on two edges has train files with rock over them so the flooding is on during a major event.  

A slow rain or even heavy consistent rain never gets above the threshold.

I want to creat a mini dam and that to work.

Can you run underground perforated piping to shed the water away from that area ?

I already have underground perfrorate piping to shed water with a stone covering around the permiter of the slab on 2 sides.

1 side is a hill the other side is the house. 

I probably would have to dig up the hill and put ohter pipe to caputre the water running down it.  But that is highly lanscaped.  I still think a dam and raising the door would be better.

Again this only happend once and during a strong downpoor.  

I've seen curbing made using hot top. That might work if you don't mind the look of the hot top.

hot top?

Probably the wrong terminology. Maybe I should have said asphalt.

I've heard it referred to as hot top too.  I figured it was because they paved over the old brick and concrete roads.  I had a friend in the asphalt paving business and he always referred to asphalt as concrete.

Thanks all I am thinking of more like exposed concrete.

 

Why not pour a concrete curb that slopes downward away from the door?  The existing door could stop against it.  I believe there are bonding agents that will create a waterproof joint between the new and old concrete.  If you want to raise the door you could ramp the curbing to the inside of the house then you have ramps on both sides of the curb.
