Post Crete

[stanbesida]

I have three St. Bernards and have slabbed the back yard to stop them making a mess in the house. There is a gap between some of the slabs and I have filled them with cement a couple of times but it hasn't been a great success so I was going to purchase some Postcrete as it dries much quicker than cement so I wondered whether anybody has any idea whether it would work?

Something like this gness (Batbox)?

Sorry Stan, Wrong thread! :o(

When you say, " it hasn't been a great success" ... what exactly is the problem ??
Does it break up and crumble after a while, or are you having problems getting the mix in between the gaps nice and neat ??

Quick-drying isn't important in this situation, Stan. If you do want that, then a simple "accelerator" additive is all you need.

Postcrete is a concrete mix. Not designed for this. It has coarse aggregate (chippings). Not what you need when grouting.

As Giz has said, it would be interesting to know what problems you have had.

many thanks for your answers, and I am sorry that I put it under the wrong topic. I have managed to get the cement in the gaps but it does break up and crumble within a very short period of time, I assumed that I had the wrong mix but it was a bucket full that I had got from the building site up the road from me and assumed that it would be fine, also the dogs have managed to scrape some of it out, hence the reason that I thought of getting something that dries quick.
