I just got done with my underground piping and thought I would pass on a new product that I used. It was a pourable form of closedcell foam. http://www.masterpkg.com/index.htm
First some background on what I'm doing. I am redoing my system and putting 4-500gal tanks next to my house. My eko-80 is 100ft away in a shed. I had these 12in cement culverts so I placed them in the ground. Inside them I used 6in black drain pipe and inside that I ran my pex. Two 1in supply and Two 1in returns. They were wraped with two turns of bubble/bubble/foil and placed inside the 6in pipe along with extra tubing. I wanted to have 3in of foam in the culverts around the pipe and was going to have a contractor come and foam it or use tigerfoam.
In my wanderings on the net I ran into the Masterpac site and gave them a call. I talked to him and he thought there pourable foam would do what I wanted. I bought some (2-5gal cans of A and B) $500 pls shipping He also thought I should buy the cleaner and gloves and measuring containers. ($65) He said the yield should be about 60cubic feet. Shipping ended up at $150 ( not happy)
Now the advantage of the pourable foam was the lower cost because there is no hasmet charge in shipping.
The foam came and I started to use it. One quart A and one quart B pour into container mixfast and pour. Well I was pouring into a hole and this stuffstarted to foam with in 5 seconds and it didn't have time to run very far into the culvert. Bottem line I didn't get the yield I needed and didn't fill where I wanted. It might work on a trench but you had to be FAST or else. I wasn't happy at all.
That monday I called them and told them what had happened. He called me back and said that he had a different product that they use to make surf boards from.
closed cell, 200f+ and VERY slow rising. He sent me some and after the third shipment because first fed-ex and then ups damaging the shipments I got it last Friday. I used it Sat. and here are my thoughts on the next post
