Retrofit Railing & Post Anchor Service
Offer a mobile service to core 1-3/4 in holes in slabs/steps for epoxy-set posts and threaded rods in existing concrete. Faster than demo/re-pour, ideal for handrails, sign stanchions, and string-light poles. Durable one-piece bit lowers consumable costs.
Small-Diameter Penetrations for Trades
Partner with electricians, low-voltage, and plumbers to provide clean 1–1/3/4 in wall and slab penetrations for 1–1/4 in EMT, 1 in–1–1/4 in PVC sleeves, and condensate/drain lines. Include core sealing (firestop/foam), grommets, and exterior flashing as a turnkey upsell.
Retaining Wall Weep Hole Upgrades
Market a drainage improvement package for failed landscape walls: core periodic 1-3/4 in weeps, install pipe sleeves with fabric filters, and add gravel relief. The low-friction core speeds work in dense block; straight holes reduce face spalling and callbacks.
On-Demand Micro-Coring
Per-hole or half-day service for GCs and homeowners who need a handful of masonry holes without hiring a diamond coring crew. Bring SDS Max hammer, dust extraction, and patch materials. The tool-free centering bit accelerates multi-hole layouts across projects.
Upcycled Concrete Decor Sales
Use harvested core plugs to produce coasters, candle holders, pen cups, and minimalist planters. Sell online and at markets; offer custom sets from clients’ old patio stones for sentimental value. Low consumable wear and fast coring keep margins healthy.

Removable String-Light Pole Sockets
Core 1-3/4 in holes in a patio slab to set short lengths of 1-1/4 in galvanized conduit as sleeves. Grout flush so poles can slide in/out for party lights or shade sails. The alternating tooth pattern helps keep holes plumb, and the tool-free centering bit speeds multi-hole layouts.
Concrete Plug Candle/Planter Set
Core plugs from a sacrificial paver or stepping stone, then sand and seal the cylinders to make tea light holders or mini succulents. The low-friction core reduces binding so the plugs come out cleaner; harvest the slugs and finish them with felt bottoms.
Through-Wall PVC Herb Pods
Drill 1-3/4 in penetrations through a garden CMU wall and insert 1-1/2 in PVC couplings as sleeves. Cap the outside with a trim ring and plant herbs in each sleeve for a living wall effect. Precise centering keeps the pods aligned in a grid.
Patio Umbrella/Base Inserts
Create recessed sockets in concrete to accept umbrella poles or removable posts for privacy screens. Core, vacuum, epoxy-set a metal sleeve, and cap when not in use. One-piece carbide construction handles repeated holes without loosening.
Drain-and-Glow Retaining Wall Accents
Add weep holes to a small garden retaining wall using 1-3/4 in cores, then insert short perforated sleeves wrapped in geotextile and snap on decorative grilles with tiny solar LEDs. The improved centering helps avoid block face blowout.
