I just got a quote for $30,000 for a cement foundation for a home. I'd like to know if anyone has seen or experimented with alternate foundation materials that would be dramatically less expensive than traditional cement?

Slipform masonry is what first comes to mind without knowing the strength of your back, subsoil type and resources available.Neihring or Kern wrote a book about it if memory serves.

Depending on your frost depth and need for a basement, a frost protected shallow foundation might be an option.  I believe they're done in conjunction with what's called a Swedish Skirt insulation system.

I recommend getting at least 3 other quote.
Can you post some pictures of the planned homesite?

Avg For Comparison
Foundation Type    Avg Per Sqft          Average Total Cost
Concrete Slab       $4/sqft                 $4,500 - $12,000
Slab&Stem Wall    $5/sqft                 $7,000 - $21,000
Pier & Beam         $5/sqft                 $8,000 - $15,000
Crawl Space         $7/sqft                 $8,000 - $21,000

Whats the size of your basement floor.
Is this going into bedrock, riverside pier, are they including a full basement into the quote and clearing the land, do they have to pay a $20,000 impact fee.

Can you post a more itemized breakdown e.g.
Service                      Cost Range
Permit                       $500 - $2,000
Grading& Excavating  $500 - $9,000
Concrete                   $3,250 - $13,500
Form&Finishing          $1,000 - $5,000
Reinforcement           $150 - $750
Sealing                     $600 - $6,000
Inspection                 $80 - $1,300
Total                         $6,080 - $37,050

How much does concrete?
Concrete costs from $113 to $126 per cubic yard or between $2.83 to $3.57 per square foot depending on the thickness of the slab poured (6inches is the avg). It will cost an additional $2.52 to $2.60 per square foot for the labor.

That $30,000 is not because cement/sand/water/plywood is expensive. It is most likely due to government fee or grading cost. When you get the other quotes if it isn't $15,000 or less ask for a breakdown.

For the original vendor quoting you the $30,000 tell him that you can get the concrete delivered yourself and what will a new quote look like. If you give me your city,state and house size, I can figure out exactly how much they will charge. And give you a vendor to call.
 
Mo-om! You're embarassing me! Can you just read a tiny ad like a normal person?
