From the start, material performance was the driving force behind our handcrafted products. Lessons learned by Hartstone’s founder, Todd Hart, passed down from his family’s three generations of work in multiple facets of the concrete industry are cornerstones in the Hartstone mix design & fabrication process. All Hartstone products are handcrafted and slow-cured at a constant 56-58 degrees in a former limestone mine in Louisville.
Hartstone is a truly unique form of architectural pre-cast. It is the result of our passion to perfect the world’s most flexible, beautiful, and sustainable building material. At Hartstone it is our pleasure to conceive and construct inspiring spaces that showcase our materials’ warmth and enduring beauty.
Hartstone products are specifically created to each order’s unique color, texture, and dimensional specifications. We do not merely “manufacture” our products and hold them in inventory until they are sold. We hand-fabricate specifically to each client’s request and preferences.
- Quality and Durability – Hartstone is continuously tested by independent labs as part of our quality control program. Hartstone exceeds the concrete industry’s ASTM standards with compression strengths exceeding 6000 psi, and water absorption rates less than 4%. We lead the industry in our material performance and are proud to offer an industry leading lifetime warranty on our products.
- Aesthetic – Hartstone is a unique recipe of the very best cement, limestone, sand, and other natural aggregates. And all of our products are hand-fabricated. The combination of which produces a very unique and organic finish.
- Extensive Product Offering – Hartstone can also be crafted into custom architectural elements such as wall caps, columns, mouldings, fireplaces, furniture, signs, etc. Custom cast stone pieces are complimentary to our legendary hand-crafted tiles and are an important part of creating inspiring spaces.
