Cement Slab Under Deck

[TKO_PUNCH]

I'm planning on having a slab poured under my deck and was wondering the cost. I have been saving money all winter long for this project, but am wondering if I need to start padding the fund a little more.

The deck size is 16' X 24' This is a little too large to do it myself, so I'll have someone do this project. Does any one have a rough estimate what this would cost me? Also, anyone have recommendations of services for the Zimmerman area?

Thanks

Yep, I know someone who can probably do it for you. He is on this site. Hopefully he will chime in soon. Not sure if I can mention names.

Hey TKO Punch,

shoot me an email, greg at [YouNeedAuthorization] dot com

You should be able to get this done for around $1200. That includes concrete.

I am actually in need of replacing my exsiting slab, and increasing its size. Would like to know if anyone on here is interested. I live in the west metro.

Another question...is it possible to pour a slab that wont heave in the winter? My brother has one. For some reason mine heaves every winter and cause some headaches in the spring.

make sure the gound or area is level and use a good fill, I would use sand, if you don't have a good enough level base or try to pour on dirt it will heave, also if do pour on sand make sure you make some groves while finishing it so it can expand/contract as nature dictates

Thanks BigWade. I'm not going to do the project myself. I think thats where it went wrong originally. The people we bought the house from did it themselves. I'm sure it is poured on top of dirt.

[BigWadeS]

thats a big problem and it is a common thing you see more and more and people think they will save money by not using the proper fill but pour on black dirt and you are re-doing it every 3 years

[BGP]

So are you saying that with the proper fill I should not have the heaving?

[Surface Tension]

An unheated slab will heave. The idea of removing the topsoil and then proper fill is to give it a good even base. When it heaves it heaves as a whole.

Let me remind folks this is not a place to solicit for hire or work wanted.

BGP,

While it is very common to have frost heave here in our climate you can minimize or eliminate heaveing if you install a good sand or class 5 base 4" thick under your concrete.The purpouse of this base is to allow water to disperse under yor slab and not saturate the ground as soil/clay will do.Another crucial part is the make sure that the adjoining landscape is graded properly to allow water to flow away from the area. Moisture is the cause of frost heave,so if you eliminate/minimize the amount of water via proper grading in adjoining landscape (make sure gutters are not dumping in this area also)and have the proper fill(sand/class 5) installed you should not have a problem with heaving(or it will be minimal).I have removed and replaced many improperly installed slabs and after proper installation and advise to H.O. on proper grading... problems solved...

Hope this helps.

Sand is the best fill,class5 is for roads & drives it contains clay for compaction and adhearence of the sand ,gravel,

[boatfixer]

Sparcebag is right. Use sand for fill, the clay in the c-5 will hold moisture.

[prechlerker]

make sure you tamp it after grading the fill to prevent settling.
