We have a swimming pool wall which has large granite slabs as coping stones. These are at /below water level and the water flows over the stone in to a channel. My issue is that some of these stones have some water ingress underneath and there are some wet voids underneath with some of the stones loosening. I do not wish to remove these. I could inject something into the grout joints. Does your product expand in the void and seek out moisture?

Our current learning is that the Acrylic C120 Impregnant shows little or no sign in contraction/expansion in curing or swelling in contact with water. There will be coefficient of thermal expansion, the effects of which are likely to be dissipated within the grouting. The impregnant itself is passive and flexible.
You would need to consider250ml Cartridge injection application. Drill a feed hole to take the nozzle. Do not inject fluid into mixing nozzle until you are ready to commence injection. Curing is fast. For peace of mind, Impregnant may be pre-chilled for application, without detrimental effect (fridge freezer box or freezer or co2 dry ice).
