“The two-way radio system from Foresolutions has been a real asset to our operations. The reliability of the radios and their ability to perform in challenging environments has been vital for maintaining effective communication across our sites. The added safety features give us peace of mind, knowing that our workers are well-protected.”

Overview

CEMEX UK is a leading supplier of building materials, operating an extensive network of quarries, cement plants, and distribution facilities across the UK. These sites support major construction and infrastructure projects and require reliable coordination between mobile plant operators, site supervisors, weighbridge teams, and maintenance staff.

Operating in large, noisy, and often remote environments, quarry operations depend on fast, reliable communication to maintain productivity and ensure safe interaction between workers and heavy machinery.

To address these challenges, Foresolutions designed and deployed a robust two-way radio communication system across CEMEX quarry sites, ensuring reliable coverage and improved safety across all operational zones.
The Challenge: Communication Across Large Quarry Sites
Quarry environments present several unique communication challenges that conventional systems such as mobile phones struggle to overcome.

Large Geographic Footprint
Individual quarry sites can span hundreds of acres, covering extraction pits, processing plants, stockpile areas, weighbridges, and dispatch zones.
Many of these locations sit in rural or semi-rural areas, where mobile network coverage can be unreliable or completely unavailable. This makes mobile phones unsuitable for real-time operational communication.

High Noise Industrial Environments
Quarry processing equipment such as crushers, screeners, and conveyor systems generate constant high levels of ambient noise. Operators working near heavy machinery require communication devices that provide loud, clear audio that cuts through background noise without requiring workers to stop operations.

Coordination Between Mobile Plant and Ground Teams
Quarry operations involve constant movement of:
  • Wheeled loaders
  • Dump trucks
  • Excavators
  • Site vehicles

Ground teams including banksmen, maintenance staff, and weighbridge operators must coordinate closely with these operators. Without reliable communication, teams may rely on line-of-sight hand signals or physical movement across the site, which can slow operations and introduce safety risks.

Multi-Zone Operational Coordination
Efficient quarry operations require continuous communication between several areas:
  • Extraction pits
  • Processing plants
  • Stockpile areas
  • Weighbridge stations
  • Dispatch zones

Breakdowns in communication between these zones can cause vehicle queues, production delays, and operational inefficiencies.

Lone Worker and Emergency Safety
Maintenance engineers and inspection staff frequently work in isolated areas of the quarry, including:
  • Elevated structures
  • Confined spaces
  • Remote areas away from the main plant

Without reliable communications, raising an emergency alarm can be difficult, creating a significant safety concern.

The Solution: 
​Two-Way Radio System Deployment


Following a comprehensive site survey, Foresolutions implemented a tailored two-way radio solution combining handheld radios, vehicle-mounted units, and repeater infrastructure to ensure full coverage across the quarry site.

Handheld Radios for Site Personnel

Rugged handheld radios were issued to:

  • Weighbridge operators

  • Plant supervisors

  • Maintenance engineers

  • Banksmen

  • Site staff

These radios are IP-rated for dust and water resistance, designed to withstand drops and vibration common in quarry environments.

The units provide high-volume audio output, enabling clear communication even in high-noise processing areas.


Vehicle-Mounted Radios for Plant Operators

Heavy plant equipment and site vehicles were fitted with vehicle-mounted two-way radios, including:

  • Wheeled loaders

  • Dump trucks

  • Excavators

  • Site utility vehicles

The radios allow operators to communicate using hands-free or push-to-talk controls, ensuring communication without distracting from machine operation.

Because they are wired directly to vehicle power systems, the radios provide continuous operation throughout the working shift.


Site-Wide Radio Coverage Infrastructure

To ensure consistent communication across the entire quarry, Foresolutions installed radio repeater infrastructure designed specifically for the site layout.

This system provides coverage across:

  • Extraction pits

  • Processing plants

  • Stockpile areas

  • Weighbridge locations

  • Dispatch and logistics zones

Previously difficult areas — including lower quarry levels and indoor plant buildings — now maintain clear and reliable radio coverage.


Emergency Alarm and Lone Worker Protection

All handheld radios were configured with emergency alarm functionality, enabling users to trigger an alert to the site control point instantly.

Lone worker monitoring was also enabled for staff operating in isolated areas. This includes:

  • Automatic check-in prompts

  • Timed response monitoring

  • Escalation alerts if a worker does not respond

These features significantly improve safety for workers operating outside the main operational zones.


Equipment Designed for Quarry Environments

All supplied radio equipment was selected for reliability in harsh aggregates environments, including protection against:

  • Dust ingress

  • Moisture exposure

  • Mechanical shock and vibration

The system operates on licensed radio frequencies, ensuring a secure and interference-free communication channel dedicated to quarry operations.

Results: Operational and Safety Improvements

Since deploying the two-way radio system, CEMEX UK has seen clear improvements in communication, efficiency, and safety across its quarry operations.


Faster Weighbridge Coordination

Weighbridge teams can communicate directly with loading operators and dispatch staff in real time. This allows teams to prepare for incoming vehicles, improving turnaround times and reducing queues.


Safer Plant and Ground Team Communication

Banksmen and ground workers can speak directly with plant operators via radio rather than relying on hand signals. This reduces the need for personnel to enter active plant areas and improves safety around moving machinery.


Quicker Maintenance Response

Plant operators can report faults immediately without leaving their cabs. Maintenance teams can be dispatched straight to the correct location, helping minimise downtime.


Improved Lone Worker Protection

Maintenance and inspection staff working in isolated areas now carry radios with lone worker monitoring and emergency alarms, ensuring any incidents are identified quickly.


Better Site-Wide Coordination

Reliable radio coverage across the quarry allows supervisors to coordinate operations between the pit, processing plant, stockpiles, and dispatch zones from a single communication platform.
