Hello Ladies and Gentleman, I just thought it would be nice to share this project I had to do while on my deployment to afganistan. Their currently is no drain for this building, so everytime we needed to dump some liquid or water we would have to walk about 30FT away from the building to do so. On top of that, I also got assigned to create a Roof for this deck we have right next to it. I suggested the idea of creating the drain so it can support all the rain water from the roof and any liquids needed to be dumped. This pit was starting to smell really bad with mop water, milk, coffee, always being dumped into it.

Project Scope-
Was to dig out the drain and grade the earth around it so it has a slope towards the end.
At the end put in a 4" PVC pipe that drains all the water to about 30' away from the building, near a storm drain.
Fill in the pit with concrete so all the water can drain away easily and not sit and create a odor.

 

This Is how the Pit looks like after a little bit of hacking With The Pickaxe

Me using the Pickaxe

I Setted the forms with a gradual slope at the end as well as graded the subbase.

I tamped some 1"1/2 rock into the dirt and put some #3 Rebar spaced 12"OC horizontally.

Troweling the concrete so that it is level with the forms

I also made a contraction Joint, to help with cracking and as well as helping small amounts of water to run down.

It gets real hot during the day, so I covered the area with plastic sheet to aid hydration

 

If I could go back I would have Snapped a Chalk line or used a laser to help me get the contraction joint perfectly centered

 

Same Setup here just repeated what I did, #3 Rebar and 1"1/2 rocks tamped

I needed to create a sidewalk because the grates wouldnt reach to the end where the concrete slab meets the earth. Also needed to run the 4" PVC pipe through it for the drain. So i Just Looped the rebar around the 4" pipe. Of course I made sure the PVC pipe had enough slope.

I Started to lay the concrete in the biggest spot first which was the sidewalk and pvc and then i work my way up

I was mixing 80 pound bags about three bags at a time in this garbage can. I used the Collomix Xo6, And even still i felt like I can add another bag to the mix. But the garbage can was getting heavy enough to move bymyself.This drill was expensive but defiently did its job, I need to make a review for it.

After the Concrete has Dried

How the sidewalk and PVC turned out

I wrote out my Organization's name in the concrete , Just had to do it.... The little kid inside of me took control

So we started digging a trench so we can run the 4" PVC

Gluing up the Pipe

Digging is not fun.

I hope you guys think I didnt dig all that on my own

Thats a long run of PVC

At the end of the road ( or should i say Pipe)

Tested the drain before backfilling, it works great.

Back filled all the earth and called it a day!

 

As you can see I screwed to TAPCON concrete screws to hold the mini screen right before the PVC pipe. Also started laying out the rebar for the concrete walls.

This is currently were I'm at, I can only work on one side of the walls due to the space limit, I found myself stepping on wet concrete and having to trowel it again. More Pics To follow, Any questions?

 

Hey sorry I haven't been on here a while, been busy. Anyways here's a picture of what it looked like a week ago, I will post new pictures probably tomorrow.
