Can you add mosaic tiles, glass etc to it before it hardens? What keeps the weeds from growing between the flagstone?

[@perviousproducts6648]

Yes, decorative stones, tile, glass, etc. can be embedded in PerkGrout as it is being placed.
PerkGrout is similar to concrete, so the vast majority of weeds cannot grow through joints filled with it. Some very aggressive weeds like bermuda grass that spread by underground runners could make it through. In cases like this, it is recommended to treat the joints prior to installing PerkGrout or spreading a double layer of weed fabric in the bottom of the joints.

Is this product available in Canada? If not where do you buy it in the USA?

[@perviousproducts6648]

PerkGrout is currently only being sold in northern california. We can ship it throughout the continental US, but it is concrete (heavy), so it is not inexpensive to ship:) It costs $14 each 30 lb bag for the shipping. If more than 2 bags are ordered the shipping cost can be reduced to $12 each bag. Unfortunately at this time, the cost to ship to Canada is just too prohibitive.
Thank you for everyone's inquiries. We are working to increase our distribution shortly.
