Zero bars? No problem. We bring the Cell Network to your site.
Whether you're breaking ground in a remote area, working below ground level, or surrounded by steel and concrete—poor cell signal is a daily frustration on South African construction sites. From delayed comms with suppliers to struggling to send plans or make calls, weak signal slows progress.
Designed to handle tough environments and remote locations, our systems ensure your site office, container, or crane has dependable cellular coverage—no matter the network.
The Unique Challenge of Cell Signal at Construction sites
Construction sites have unique challenges to ensure strong cellular reception throughout all phases of construction. These signal needs change as construction progresses.
At the start of a construction project, there might be good cellular reception, but as the building takes shape certain areas might start to suffer from poor cellular reception. This means that cellular signal solution designs needs to be adapted as the project progresses.
Reliable Communication Saves Lives
Clear communication saves lives. Whether it’s coordinating teams or calling for help, your crew needs dependable signal—especially in emergencies.
Poor coverage can delay emergency response and put lives at risk. First responders must also have working signal to operate effectively on-site.
Our boosters ensure strong, reliable mobile reception across your construction zones—because safety depends on connection.

Signal Success Story
We completed a cellular signal booster installation for Raubex, one of South Africa’s leading construction companies. The solution was designed to improve mobile connectivity across their site offices, ensuring reliable communication for project teams and supporting the performance of GSM-based systems. The installation significantly enhanced signal strength, helping Raubex maintain efficient operations in a challenging coverage area.
Our 4 Step Installation Process
Every professional repeater installation follows a proven 4-step process. Our certified installers are fully trained to ensure each installation meets our strict quality standards.
Step 1
Initial Review
Send us your building plans. Our team will create professional heat map designs showing projected antenna signal strengths per floor. We'll also generate a Bill of Materials (BOM) and a detailed cost estimate.
Step 2
On-Site Survey
We visit your building to conduct a comprehensive site survey using a signal test analyser. A signal expert will guide you through every step of the process to ensure accurate data collection.
Step 3
Design Proposal
Using the data from the survey, we refine the system design and generate a final, accurate BOM tailored to your site's needs.
Step 4
Installation Support
Bolton’s expert installation team handles the full setup, ensuring the system is installed correctly for maximum performance and reliability.

5G and LTE are expected to drive a 40% increase in data demand on construction sites over the next 5 years.
Construction Signal Booster FAQs
Is there a way to boost cell signal in a building?
Yes! A cell signal booster is the most effective way to improve mobile connectivity inside a building. It works by capturing the existing outside signal, amplifying it, and redistributing it indoors using antennas. Bolton Technical offers WilsonPro signal boosters, ideal for construction sites, office buildings, and prefab structures.
Do cell phone signal boosters really work?
Absolutely! Signal boosters amplify weak cellular signals to provide stronger call quality, faster data speeds, and more reliable connectivity. They are especially effective in construction areas where interference from materials like steel, concrete, and insulation can weaken the signal.
Do cell phone boosters work through walls?
Yes, but with some limitations. While a signal booster strengthens indoor coverage, thick walls made of concrete, metal, or glass can reduce signal penetration. To overcome this, we use multiple indoor antennas or strategically place the booster to ensure optimal signal distribution throughout the space.
How to get cell signal in a concrete building?
Concrete buildings are one of the biggest barriers to cellular signal. The best solution is a commercial-grade signal booster, such as the WilsonPro A1000 or A8000, which uses an outdoor donor antenna to pull in the strongest available signal and distribute it inside. Ceiling or wall-mounted antennas then broadcast the improved signal throughout the building.
What causes poor cellular signals on construction sites?
Common factors that weaken cellular reception include:
- Distance from cell towers
- Signal interference from steel, concrete, and insulation materials
- High network congestion in busy areas
- Remote site locations with limited coverage
Which signal booster is best for construction sites?
For large-scale sites, we recommend the WilsonPro A1000 or A8000 for comprehensive indoor coverage. For contractors and workers on the move, the weBoost Drive AM100-Pro boosts signal in vehicles and trucks.
Can signal boosters improve connectivity in temporary site offices or prefab structures?
Absolutely! Temporary offices and prefab buildings often suffer from poor indoor signals. Our WilsonPro boosters stabilize mobile signal, ensuring reliable communication for project managers and supervisors.
Are signal boosters legal in South Africa?
Yes, all Bolton Technical signal boosters are fully ICASA-approved and comply with South African regulations, ensuring safe and legal operation on your construction site.
How difficult is it to install a signal booster on a construction site?
Our boosters are designed for easy installation. We offer:
- DIY-friendly kits for smaller setups
- Professional installation for large construction projects. Our team can assess your site and recommend the best setup.
Can signal boosters withstand harsh construction site conditions?
Yes, our outdoor antennas are built to endure tough environments, including dust, rain, and extreme temperatures, making them perfect for construction sites.
