Many of Buchanan's historic homes feature sturdy concrete porches that have weathered over time. Our Stone Overlay system is the perfect way to update them without destroying the original footprint. We veneer your existing concrete with natural stone or architectural pavers using industrial bonding agents. It is a quiet, respectful renovation that instantly boosts your curb appeal, giving your home a fresh look that honors its history.
Polymer-Modified Bonding for Concrete Resurfacing
When an existing concrete porch or patio is structurally sound but aesthetically dated, we utilize a stone overlay system. The critical failure point in overlays is the bond between the concrete and the new stone. We mitigate this by using a polymer-modified mortar specifically engineered for exterior freeze-thaw environments. We do not rely on standard masonry cement. We mechanically profile the existing concrete surface (grinding or scarifying) to open the pores, ensuring a chemical and mechanical bond. This allows the stone veneer to flex slightly with the concrete substrate during temperature swings without delaminating.
Technical Specifications:
Surface Prep: Mechanical scarification to remove sealers and open concrete pores.
Bonding Agent: Polymer-modified, high-strength exterior mortar (ANSI A118.4 or better).
Material: Natural stone or high-density pavers calibrated for overlay applications.
Joints: Weather-resistant grout or polymeric sand depending on stone type.
Perimeter: Soldier course borders for a finished, structural edge.
Execution & Finish
We verify the existing concrete pitch to ensure water continues to shed away from the home. The stone is laid in a wet-bed mortar, buttered on the back to achieve 95% coverage or higher, eliminating voids where water could collect and freeze. We finish the perimeter with a vertical stone veneer or coping to hide the old concrete edge, creating the illusion of a full-depth masonry construction.
Revitalizing Historic Porches
Many of Buchanan’s classic homes feature sturdy but weathered concrete porches that detract from their curb appeal. Rather than the invasive and expensive process of demolition, we offer stone overlays to revitalize these entrances. We resurface the existing concrete with high-quality natural stone or pavers, preserving the original footprint while giving it a sophisticated facelift. This is the perfect solution for homeowners who want to maintain the historic integrity of their property while correcting surface pitting, cracks, or discoloration.
We treat every overlay as a permanent structural upgrade. We meticulously prep the old concrete, using industrial bonding agents to fuse the new stone to the existing slab. We pay special attention to the details, installing custom-cut stone treads that completely cover the old concrete "risers," creating a seamless, solid-stone appearance. By sealing the joints with high-performance materials, we prevent moisture intrusion, ensuring your renovated porch is safe, durable, and ready to welcome neighbors during the Redbud Festival and beyond.
