Can I pour Rockite into a cardboard mold to do this?** A: I have had a lot of success with Rockite in plastic containers, e.g. cottage cheese container. The Rockite might stick to the cardboard. I would suggest trying a smaller scale version with the cardboard to see how it reacts. If it does stick, you should be able to sand off the small cardboard remnants. **Q: I have read this product could be used to fill small cracks in your driveway. Has anyone tried this?** A: Yes! I used it when we had to to take out some burglar bars. Which left wholes, cracks & splits in the brick ... worked great!! **Q: can rockite be sanded?** A: I would say yes if you would try to sand other concrete. I wouldn’t personally **Q: Can I drill into Rockite?** A: i'm sure you can drill a hole in it, i don't know if will crumble over time. i generally use it to anchor bolts ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by E***T on September 18, 2025* ### ⭐⭐⭐⭐⭐ Review *by J***O on August 6, 2024* ### ⭐⭐⭐⭐⭐ Review *by S***F on March 26, 2026* ## Frequently Bought Together - HARTLINE 10001 Rockite Expansion Cement 15 Min 1 Lb - Architectural Mailboxes 7680B-10 MB1 Mount Mailbox and In-Ground Post Kit, Medium, Bl - 60 PCS White Mailbox Numbers, Vinyl Waterproof Stickers for Outside, Address on House, Big Mail BOX Number, 6 (3" x 4 sets, 4" x 2 set,0-9) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/7880979-hartline-10001-rockite-expansion-cement-15-min-1-lb](https://www.desertcart.tn/products/7880979-hartline-10001-rockite-expansion-cement-15-min-1-lb) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-30*
