Project Ideas

Business

Dust‑Controlled Tile and Thinset Removal

Offer fast interior tile/thinset/demo with OSHA Table 1–compliant dust control using the DWH052 attachment and a DCV585 extractor (Wireless Tool Control for auto‑on/off). Typical pricing: $3–$6/sq ft tile, $1–$2/sq ft thinset; upsell surface prep and debris haul‑off.


Micro‑Trenching for Trades

Create 2–6 in channels in slabs for electrical, low‑voltage, or plumbing. Bill per linear foot ($15–$30/lf) with options for backfill/patch. The 120 V, 15 A setup mobilizes easily indoors where larger breakers or saws are impractical.


Fence and Deck Footing Extraction

Specialize in breaking and removing old concrete posts/sonotube footings and loosening compacted soil. Charge $75–$200 per post depending on diameter/depth; bundle new post setting. The included transport cart speeds yard‑to‑yard moves.


Asphalt Patch Prep and Keying

Prep potholes by squaring edges and chipping keyways for better patch adhesion, then offer cold/ hot‑mix patch as an add‑on. Target HOAs, small lots, and driveway contractors; price per patch size and complexity.


Urbanite Salvage and Install

Upsell eco‑friendly patios, paths, and retaining accents by demoing old slabs and reusing the broken pieces as ‘urbanite’ stone. Capture revenue on both removal and installation with low material costs; market the sustainability angle with before/after reels.

Creative

Urbanite Garden Paths and Seating

Break up an old patio/driveway into pavers and bench blocks. Use the flat and scaling chisels to create clean edges and texture the faces for a stone-like look, then set in compacted gravel with groundcover in joints. The vibration control helps for longer sessions, and a dust extractor with DWH052 keeps silica down while you work.


Sculpted Concrete Block Planters

Turn leftover concrete/masonry into large trough planters by pecking out cavities with the bull point, then refining with the flat chisel. Add drainage holes and chip a decorative stipple or fluted texture on the outer faces for a hand-carved aesthetic.


Wabi‑Sabi Rain Channel and Water Feature

Chip a shallow meandering channel across an old slab to direct roof runoff to a small rain garden or basin. Soften edges with the flat chisel, add river rock, and optionally set a hidden liner. This doubles as functional drainage and a tranquil water feature.


Rustic Fire Pit + Mosaic Patio

Break reclaimed concrete into arcs for a fire-ring and varied tiles for a surrounding patio. Key adjoining pieces with the self‑sharpening chisels for interlock, then set on compacted base. Use a metal fire ring insert to protect the concrete.


Anti‑Slip Texturing on Exterior Steps

Improve safety by stipple‑pecking slick concrete steps and landings, adding micro‑grooves and drainage notches. The hammer’s control and 40 J impact make quick work of uniform textures without needing specialty grinders.
