Post Fix - One Bag is not Enough can I use More?

Postby japweb16 » Sat Aug 06, 2016 3:06 pm

The post hole is only about 3/4 full of post fix and I want to fill it with more, only - of course - the new concrete will go on top of the first lot, already rock solid.

Can this be done? Obviously the bond won't be the great, but I think there are adhesives that are supposed to help in a situation like this?

Any advice and product recommendations would be welcome.

Many thanks.

make a wet mix, and just pour it in, it will bond with the old concrete

You can also just use another bag of postcrete. Throw some water in first, then the postscrete and more water. It will set like a bullet and bind to the old stuff.
