When sensitive electronics sit on a factory floor, one static spark can mean a failed component and a production loss. An ESD-dissipative concrete floor absorbs charge from workers, carts, and equipment, then safely routes it to ground before it reaches the assembly line. Laval Concrete designs and installs these systems to your ANSI/ESD spec, grounds them to your building electrical, and verifies the resistance with a megohmmeter before handoff.
A conductive floor is not the same as a dissipative floor. Conductive means electricity flows too fast and can create electrical hazards. Insulating means charge builds up and never leaves. Dissipative is the engineered middle ground: charge flows to ground at a controlled rate, safe for both the equipment and the people working on the slab.
We install ESD systems matched to your facility's ANSI/ESD standard, with the right conductive loading (carbon black, conductive aggregate) to land in the target resistance window. After the epoxy cures, we test across multiple points with a megohmmeter and hand you the verified documentation. That report is what your auditor wants to see.
We review your ANSI/ESD standard (electronics, clean room, pharmaceutical each have their own), identify which zones need dissipative coverage, and confirm the target resistance range and grounding scheme with your engineering team.
Prep and ground installation
The concrete slab is diamond-ground to the epoxy system's profile. Copper ground strips are set at the engineered spacing, then connected to the building electrical ground at designated points by the electrical contractor.
Apply ESD epoxy system
The matched ESD-dissipative epoxy (primer, body coat, topcoat) is applied with conductive elements at the right loading to achieve the target resistance range. The system cures per the manufacturer's schedule.
Test and document
After cure, the floor is tested at multiple points with a megohmmeter. Resistance readings are recorded for each zone, compiled into a verification report, and handed to you for compliance records and future audits.
The proof is in the test
Megohmmeter Verification Confirms the System Works
An ESD floor that looks right but fails the resistance test is worse than no ESD floor at all. It creates a false sense of protection while static charge still reaches your components. That is why we never hand off an ESD installation without megohmmeter verification across the finished slab at multiple test points, with documented readings that fall within your ANSI/ESD spec.
The verification report becomes part of your facility's compliance file. When an auditor or customer asks for proof that your ESD zones are protected, you have the data. We also coordinate with your electrical contractor on the grounding connections and with adjacent dust-proof sealing or warehouse floor coating in non-ESD areas so each system performs in its zone.
Resistance ranges, grounding, verification and which manufacturing zones need ESD.
With a megohmmeter (high-resistance ohmmeter) at multiple test points across the floor, comparing to the ANSI/ESD standard's specified range. The reading needs to fall inside the dissipative window, not too low (conductive) or too high (insulating).
Only zones where ESD-sensitive components are handled. Electronics assembly, clean rooms, repair benches, certain pharmaceutical processes. The rest of the facility uses standard manufacturing flooring. We define the zones with you and your safety/engineering team.
Copper ground strips embedded in the floor at the engineered spacing connect to the building electrical ground at designated points. The electrical contractor coordinates with us on the connections and verifies the grounding scheme.
Many years with proper maintenance. ESD-compatible cleaning chemicals preserve the system; standard wax or solvent-based cleaners can compromise the resistance range. The maintenance protocol is part of project handoff and includes recertification cadence.
Similar to other epoxy systems plus the grounding install and verification steps. A typical zone takes a week to install and verify; multi-zone facilities stretch to several weeks with phased install. The schedule is in the quote.
ESD floor installed and verified across our assembly zone. Resistance documentation supported our customer compliance audit. The system has held for two years of daily operation.

★★★★★
They knew the ANSI/ESD spec cold, coordinated with our electrical contractor on grounding, verified with the megohmmeter at handoff. No improvisation, no audit findings.

★★★★★
Stricter clean room ESD spec, they hit it. Documentation, grounding, verification all in order. The auditor specifically called out the install quality.

★★★★★
Phased ESD install during off-shifts so production never stopped. Each zone verified before reopening, no resistance drift between zones. Real coordination.
