You'll hear a lot of claims combined with fancy marketing material.
When the Foam sales folks start with their fancy facts and figures, ask them one question.
How did that Major Law Suit turn out at the Salt Lake International Airport?
Another thing, if it's so great, why don't Construction Managers lay out a layer of this foam before they pour concrete or lay asphalt?
What they do is use RoadBase, just like you would do if you built your own home.
Just like WE USE.
Every year we get some local contractors sold on the Polyurethane Foam. "Oh, it's the Latest thing." They go to The World of Concrete show in Las Vegas and come back with the Equipment and marketing material they purchased.
They have lots of marketing material to "sell" folks on the concept and it's always the same.
"Look at these pictures of the mud jackers. These jobs failed."
"The Mud Jackers are Dinosaurs, a dying breed. They use obsolete technology." Folks, the Obsolete Technology one works becauses we are conditioned to think newer is always better.
Really the "The Newest Thing?" Polyurethane Foam has been around since the beginning of World War II where it was used primarily in the insulation industry and only in the last few years have marketing companies tried to adapt it to the concrete industry. They are making a lot of claims so you need to get the facts.
One important fact is the Cost. Their numbers ALWAYS come in at Least 50% more and usually Double our pricing.
They include a contract with an esclator clause that if they use more material than expected, you pay more. We have NEVER seen a job where they didn't activate this clause, and guess what, you are Locked in, you signed a contract.
One of the points they continually make is "The holes we drill are much smaller."
Thats like saying after you use a different color of paint on a touch-up of your kitchen rawers, "Oh, it looks close, it's only a small touch-up." Wouldn't you use the same color of paint?
Isn't the issue How it Looks, not how big?
There is a place for the Foam and it's NOT in Concrete Raising. It's been used for years in insulation and void fill but there are serious issues in Raising. Think about it. You are going to try and raise concrete that will weigh from 5,000 to 35,000 lbs. with foam that I can rip apart and even crush in my hand. I can show you 7 failures just from 2016-2017 (Two listed here.) We have already fixed four and are on schedule for two more.
So why do the manufacturers at these concrete shows push it.
Consider this. Say I'm an equipment manufacturer. I sell you a machine. I now only have a future opportunity of selling you parts.
BUT, if I sell you a Foam machine, I not only get your parts business but All the material you put through that machine, on every job you do. And I'll include a disclaimer that I'm not responsible for any warranty, you are. Good deal for me, bad deal for the consumer.
Now you see why most of these Foam guys go out of business in just a few years.
Their marketing makes a lot of claims.
"The Foam will not deteriorate." False. Water, UV Rays even Air will cause deterioration.
"You get 100% compaction." False. The product has millions of microscopic air holes. How else could I crush it in my hand?
"It's Totally Safe." You be the judge. By law, if asked they must supply an MSDS Sheet which lists Poly Diisocyanate as a primary ingrediant. Do your Research.
Very few customers think to ask for this sheet and the contractors don't volunteer it because they don't want to spook you. And if you do ask for it, "Oh, we are out right now but you don't have to worry. It's OK."
In addition, it's Flamable.
If you are convinced you need the Polyurethane Foam because you have bought into the marketing claims, we CAN do it but there are some issues.
I have an associate in Utah County who added it just to cover those cusomers who insist on using foam. I can bring him in and we'll match the other Foam guys pricing, which is usually nearly Double our price. The product is shipped in from out of state so the shipping and handling must be covered.
That escalation clause must be added because of the expensive product.
AND, no warranty. Folks, it's not a matter of IF but WHEN it will fail.
This Smithfield homeowner had the Foam Guys come out Three times till they said No More Warranty.
After Three tries, still not fixed.
Lundahl Building Systems had the Foam guys come out a couple of years ago on this High End cabin.
As you see, total failure.
This video is from a contractor in Wisconsin.
NEWS FLASH: Foam Lift is not new. Every 2 or 3 years we have a new crop of guys who attended a convention and come home with this "Latest and Greatest, Newest" equipment. In the 16 years I've been in business I've seen 14 of these companies come and go just in Utah. (There are Three new ones this year.) They spin a good marketing line and get some jobs because some people are gullible and like the title "new" even though it's nearly twice the price. Then these contractors are usually gone in a couple of years, about the time the warranties start to hit, just like the two I showed above.
And folks, I have 2 more jobs booked with unhappy foam customers who paid once for the foam, now they have to pay again to have it done right.
