At JR Marine Construction, we’re not afraid of big jobs—or big stone. Our latest delivery brought in a serious shipment of 4 x 6-foot double black granite slabs, ready to anchor a major waterfront project on Lake Simcoe. These oversized slabs aren’t just for show—they’re the real deal when it comes to durability, weight, and visual presence.
Granite That Means Business
Granite of this size plays a critical role in marine construction. It’s not just about appearance—it’s about lasting shoreline protection, wave resistance, and creating stable foundations that won’t back down from the elements. We work with materials that match our build philosophy: tough, reliable, and built to last.
Perfect for:
Custom dock and platform foundations
Erosion control along high-impact shoreline
Aesthetic natural stone integration
Long-term marine structure reinforcement
Our crews use heavy-duty barges and precision equipment to transport and place these slabs with care—because good waterfront work starts from the ground up.
