Project Ideas

Business

Epoxy Anchor & Rebar Doweling Service

Offer post-installed anchor and rebar doweling in existing concrete for pergolas, seismic retrofits, canopy posts, and equipment pads. The 31-inch drilling depth enables deep embedment; the four-cutter tip delivers round holes for reliable adhesive bond. Provide layout, drilling, adhesive installation, and pull-test documentation.


Mobile Boulder Fountain Drilling for Landscapers

Partner with landscape contractors to drill clean, straight bores through natural stone on-site for water features. Provide per-hole pricing, jigging for accuracy, and optional surface flattening for stacking. The elongated helix expedites slurry removal for faster production.


Through-Wall Utility Penetrations

Specialize in 1.25-inch penetrations through thick CMU and concrete for 1-inch conduit, sleeves, or PEX. Deliver dust-controlled drilling, core mapping to avoid rebar where possible, sleeve installation, and professional sealing (firestop or urethane) as a turnkey service for electricians, plumbers, and HVAC techs.


Railing/Post Retrofits in Masonry Caps

Provide precise, plumb bores in stair and balcony caps or retaining wall tops to accept handrail posts, light bollard bases, or sleeve-and-epoxy systems. Bring SDS-Max rotary hammer, jigs, and vac attachments to minimize dust and speed installs for metal fabricators and GC clients.


On-Call Deep-Hole Drilling Subcontractor

Offer rapid-response drilling for anchors and sleeves where 1.25-inch diameter and up to 31-inch depth is specified. Price by depth or hole count, include OSHA-compliant dust extraction, and supply as-built layout notes. Ideal for commercial TI projects needing quick, clean penetrations without full core drilling.

Creative

Stacked Boulder Fountain (Hidden Plumbing)

Drill 1.25-inch vertical bores up to 31 inches through natural boulders to route 3/4–1-inch tubing and a central alignment rod. The four-cutter carbide tip and long flutes clear slurry so you can stack stones cleanly over a basin and pump for a dramatic, low-profile water feature.


Retaining Wall Pass-Throughs for Lighting/Irrigation

Create clean, straight penetrations through thick CMU or poured concrete walls to snake low-voltage lighting cable or drip lines. Line the hole with PVC for a neat sleeve, then seal ends with grommets. The open-head design routes dust into the flutes for efficient, low-clog drilling.


Planter Umbrella/Trellis Sockets

Turn heavy concrete planters or pedestals into multi-use bases by drilling deep 1.25-inch sockets and epoxying in 1-inch galvanized pipe sleeves. Drop in umbrellas, trellis posts, or seasonal decor as needed; remove them to keep a clean look when not in use.


Pinned Stone Bench or Garden Bridge

Drill aligned holes through thick stone slabs and block legs, then pin with stainless all-thread or rebar and structural adhesive. The 1.25-inch bore gives tolerance for alignment while providing a stout, hidden connection for a rugged, sculptural outdoor seat or bridge.


Hidden Time Capsule in Masonry

Bore a deep cavity into a non-structural step, block, or faux rock and insert a sealed stainless or PVC capsule. Cap the opening with a matching concrete plug. The long 31-inch drilling depth allows meaningful storage while keeping the cache secure and weatherproof.
