Epoxy resin and natural stone paving in winter

Good day,

I have a question about epoxy resin and the laying of natural stone pavement.

At our place, a mixture of sand and something else, which I do not know exactly what it was, was used as a substructure. The procedure was as follows: The sand-something mixture was brought to the area to be paved, and the natural stone pavement was worked into it with a hammer. After all the pavement was laid, it was flooded with water. Later, the epoxy resin was used to close the joints.

I now have the following questions and really hope that someone can help me. It would be nice to know who answers my question, meaning the exact level of knowledge. By that I mean, please no guesses.

So the questions: If there was cement in the sand mixture, is it possible that in winter water penetrates through the epoxy resin and causes the pavement to crack and everything to break? That would be very tragic given the amount of money the person has already received.

In addition, dry stone walls were built; I always thought they were stacked. In any case, the walls have a solid core with a foundation. On the sides, the joints are open; on top, the joints were also sealed with epoxy resin. Same question: winter, moisture, freezing cold, wall damaged because epoxy resin is permeable to water?

Building really soon won't be fun anymore, I feel like everyone is cheating you if that were the case,
always problems

PS Thank you

Hello,

It would be nice to know who is answering my question, so to what extent their exact knowledge is.

With us, a mixture of sand and something else, which I do not exactly know what it was,

Gravel?

So the questions: If there was cement in the sand mixture, is it then possible that in winter water penetrates through the epoxy resin and damages the pavement by making it burst and everything breaks? That would be very tragic given the amount of money the person has already received.

Epoxy resin joints are weather- and frost-resistant. So also waterimpermeable - unless you insisted on a water-permeable design.

In addition, dry stone walls were built, I always thought they were stacked. In any case, the walls have a solid core with a foundation. The joints on the sides are open, on top epoxy resin was also used for jointing. Same question: winter, moisture, freezing cold, wall damaged because epoxy resin is water-permeable?

In "dirt," i.e. without a foundation, these walls would not stand for long...

Building is really becoming no fun soon, I have the feeling everyone is cheating you, if that were the case,

Where does this assessment come from?

Hi ConstructionExpert, thanks for the answer.

And starting over again, I just closed the wrong tab.

About the substructure: Gravel was delivered. On top of it a mixture of sand and something else, and the next day a mixture of chippings and presumably the same something else. The stones were embedded halfway into this mixture. Then it was flooded with water. Now the stones are firmly set in it. The other half was then grouted.

About the epoxy resin: When I now pour water on the joints, you can see small bubbles rising. Also, it is clearly visible that the water seeps into it. But the paving specialist said that it would run off over the surface. This also matches your statement that it is impermeable. On one side it says it should be water-permeable and there must be a permeable subsoil.

Now I am of course confused and the question remains, if what is between the joints is water-permeable, it won’t get damaged in winter and frost.

Hello,

On one page it says that it has to be permeable to water and there must be a permeable subsoil.

I removed the link, as you noticed => forum rules.

But it said/says: "can only be applied if incoming water is drained off through a correspondingly permeable substructure"

Now of course I am confused and the question remains whether this, what is between the joints, is permeable to water and does not get damaged in winter and frost.

You should clarify whether the "paving specialist," as you call him, has exchanged ideas with the civil engineer beforehand; at the moment it does not read that way. On the other hand, the epoxy resin execution that the paver installed does not correspond with his statement => "planned" to drain on the surface, now it seeps away.

The good news: if the substructure matches the epoxy resin execution, nothing should happen because the water can seep away unhindered. Therefore, you should also clarify exactly what this mixture of sand and "something" is and then consult with the epoxy resin supplier about its application area.
