Heavy Concrete Core Drilling & Trenches in Memphis, TN
Deep core drilling for high-voltage industrial gear and drainage slab trenches.
Heavy Concrete Core Drilling & Trenches for Memphis Projects
Heavy core drilling and trenching are the quiet enabling scopes on many Memphis industrial projects. New dock equipment, conveyor systems, electrical gear and drainage often require openings and trenches cut into slabs that are already poured, and the work has to respect rebar, post-tensioning tendons and underground utilities.
Safety and compliance are central. Cutting and coring concrete creates respirable crystalline silica, so OSHA's construction silica standard applies, with wet methods or dust collection for common tasks and a written exposure control plan. Scanning with ground-penetrating radar or similar methods helps locate rebar and conduit before cutting.
In Memphis, the work often occurs in retrofitted or occupied warehouses, in older submarkets and in new buildings getting tenant fit-outs. Power-intensive users bring requirements for deep penetrations, equipment pads and trench drain systems. Good planning includes coordination with the owner, engineer and other trades, and proper slurry management, restoration and patch details.
Memphis-Specific Considerations
- OSHA silica requirements apply to cutting and coring, so wet methods, slurry control and written exposure plans are typical.
- Older warehouses may have unknown reinforcement or utilities, so scanning before cutting is prudent.
- Occupied buildings call for dust, noise and slurry control and often off-hours work.
- Post-tensioned slabs need extra care and documented tendon locations before any cutting.
- Restoration patches should match flatness and joint requirements, especially where racking or equipment will sit.
Our Heavy Concrete Core Drilling & Trenches Process
1. Scan and mark
Locate rebar, tendons and utilities with scanning and drawings, then mark openings and trench lines.
2. Plan controls and protection
Set up wet methods or dust collection, slurry containment, and protection of adjacent areas and equipment.
3. Core and cut
Use rig-mounted coring and saws as appropriate, following the engineer's direction on rebar and structure.
4. Excavate and install
Remove concrete and soil for trenches, then support installation of conduit, drains or equipment by other trades.
5. Restore
Place dowels, new concrete or grout, finish to match the surrounding slab, and clean the area.

Does core drilling require silica controls?
Yes. Cutting and drilling concrete can release respirable crystalline silica, so OSHA's construction standard applies. Table 1 lists accepted controls such as integrated water delivery or dust collection for common tools, plus respiratory protection in some cases, and employers need a written exposure control plan and training. Confirm current OSHA requirements for your specific tool and setting.
How do you avoid hitting rebar or tendons?
Scanning with ground-penetrating radar or similar equipment, along with review of drawings, helps locate reinforcement and conduit before cutting. In post-tensioned slabs, tendon locations should be confirmed and the engineer consulted. If rebar must be cut, the engineer should approve it. Marking and verifying before drilling is standard good practice.
Can trenching be done in an occupied warehouse?
Often yes, with planning. Wet cutting, dust control, slurry containment and off-hours scheduling reduce disruption. Sections may be opened in phases so operations can continue around the work. Coordination with the owner and tenants about access, noise and safety is important, and restoration should be completed to maintain floor performance.
