Questions & Answers

Can I use to fill abandoned Underground HVAC ductwork registers indoors And put flooring over top?

Had to abandon Ductwork under slab because it occasionally filled with water. We are going to fill the registers not the entire ductwork system And replace the flooring over top. I have a one-year-old son. Is this material safe for indoor use?flooring over top. I have a one-year-old son. Is this material safe for indoor use?
Asked by: Mike
You will be better off just taking out or smashing the existing duct work at the register openings, fill the opening with good compact-able soil to the bottom of the existing slab and use concrete to finish of the rest. Use sika concrete bonding agent all around the openings to insure a permanent bond between the old and new concrete.

My house sits on cinder block footers consisting of staggered blocks, four high. The inside of the blocks are hollow. Could I pour this inside and in essence bond the blocks into one piece to help stabilize them for earthquakes?
Asked by: SavingLabor
For foundation strength it would be best to use a high strength concrete for sure. It would also be a benefit if you could use rebar to 'settle' the concrete as a vibrator would, then drive rebar through the staggered blocks into the ground, or at least to the concrete that the blocks have been set upon. That would limit the shear factor at the block's mortar joints. You cannot over-do a house foundation retrofitting.

Will this product work in areas where it snows and freezes?

Asked by: Jon
I had the same concern about how Post Mix will stand up in the weather. I secured my fence posts with Post Mix almost 2 years ago. Since then my posts have endured snow, 0° winter, 100° summer, 70+ mph wind storm. There are still secure.

I am 62 yrs old I installed a my wood fence last year it was 86 feet long with 15 4x4 posts using Sika and what is the most important part of using this is NOT to set the bag out in the sun. Keep it in the shade or in a cooler with ice when working out in the heat. Two hurricane came thought here in Ga last summer with winds between 60 to 75mph and my fence held up using and foam so if you want to break your back keep using the concrete.

I was concerned after reading the negative reviews here, but I decided to try it anyway. 6 bags helped me sink 4 12 foot 4X4's with so much more ease than concrete. (6 bags = 600 lb's of concrete) The negative reviews I've seen on here are due to 'user error' due to one of two reasons: 1) They didn't dig the hole the proper depth (obvious from the pictures) or 2) They didn't read the directions! (You mix for 15 to 20 seconds depending on which generation you buy, then snip the corner & pour. I would estimate at the 30 to 50 second mark the foaming starts and if it's still in the bag, it's gonna expand and blow!) The bag says it will fill a 3 foot deep 8 inch hole, however, I found I needed a bag and half. This might have had to do with the cool weather (just below the recommend storage temp on the bag). The posts are solid in the ground & I couldn't be happier. Would totally recommend. We'll see over time how it performs, but initially, when used as suggested it's awesome!

I rolled the bag in the direction shown on the bag and it broke the seal easily. I placed the bag over my leg and pulled it back and forth for the 15 seconds described in the instructions. Next we cut the corner of the bag off and poured the mixture into the hole. After it was poured in it started to expand just like spray foam and it filled the hole and rose a bit above the grass. The mixture does give off some heat due to the chemical reaction but not enough to seem dangerous. It set up very quick and I cut off everything that was above the grass and then back filled the hole. The post is secure and I would use this product again. I don't think its a replacement for concrete but it did work as described.

I will tell you that it is amazingly light compared to carrying a 50lb bag of cement. It's basically hard styrofoam onse it sets. It can be carved or hot knifed to shape.

I used this product to anchor a 20' flag pole and inspite of about a week of soaking rain and some pretty good winds the flag is flying high and straight. This was my first time using this product and it's easy to use...can be trimed with a keyhole saw (or alike) and clean up is easy (throw the bag away)

Used to secure 24in long 4x4 posts holding up a 12in retaining wall on both sides of a walking path on a hill. Very easy to use and fast. No waiting for the concrete to set. One bag was enough for two posts, probably could have done 3 posts if my holes were smaller diameter.

If it sounds too good to be true it probably is.....I watched the video multiple times and followed the directions. I was using this product to set posts to extend a section of privacy fence. I set my posts and waited till the next day to install 2x4s. I wanted to push on the posts a little to simulate wind just to make sure before I started installing 2x4s. The outcome was not good, I am not a big person and I was able to push the post out of plumb, multiple inches, with little effort and no rebound. I walked over to one of my previously installed cemented post that I just removed the 2x4s on and pushed with all I had and I was just bending the 4x4, when I let off it went right back to plumb. I decided I needed to remove the 6 4x4 post I just set with sika post fix and reinstall them with concrete because I didn't want my new section of fence to be leaning over after the next heavy wind. Yes it wouldn't blow over but that's because of the surrounding dirt not because of the sika post fix.
