Every construction site has areas with no phone signal. Basements, cores, risers, rural builds. SiteTalkie works where your phone doesn't — keeping your team connected when it matters most.
Construction sites routinely have dead zones where mobile phones lose signal. Workers in basements, lift shafts, risers, confined spaces, and rural sites cannot call for help when something goes wrong.
Current solutions — mobile phones, two-way radios, shouting — all have critical limitations. Phones need signal. Radios need line-of-sight. Shouting doesn't travel through concrete.
In almost every HSE investigation of a construction fatality, communication appears as a contributing factor.
Two workers are trapped in a trench collapse. They're below grade — no phone signal. With SiteTalkie, their SOS alert reaches the surface team in seconds via Bluetooth mesh. Without it, nobody knows they're trapped until someone walks over and looks.
An engineer enters a riser shaft for an inspection. Mobile signal drops to zero at level B1. With SiteTalkie, they stay connected to the team above via mesh. If something goes wrong, help is one tap away.
A crane is swinging loads over a live work area. The banksman needs to warn the crew below, but the concrete structure is blocking radio signal. SiteTalkie's mesh bridges the gap — everyone in range gets the message.
Fire alarm triggers. The site manager needs to confirm everyone is out. Mobile networks are overwhelmed. With SiteTalkie Teams, one tap sends an evacuation alert to every device on the mesh. Missing responses are flagged instantly.
In almost every HSE investigation of a construction fatality, communication appears as a contributing factor. Not because people don't want to communicate — but because they physically can't. Dead zones in basements, confined spaces, risers, and rural sites mean that when something goes wrong, the people who need help can't call for it, and the people who could help don't know it's happening.
HSE guidance on confined spaces (L101) explicitly states that "an adequate communications system is needed to enable communication between people inside and outside the confined space and to summon help in an emergency." If your current system relies on mobile signal, and that signal doesn't exist — you have a gap.
Health and Safety at Work Act 1974 — requires employers to provide adequate emergency communication systems on site.
CDM Regulations 2015 — principal contractors must plan and maintain communication procedures for all site workers.
Confined Spaces Regulations 1997 — communication equipment is required for all confined space work entries.
Management of Health and Safety at Work Regulations 1999 — employers must establish emergency procedures including reliable communication.
HSE Guidance HSG150 — construction sites must have emergency communication systems that work in all areas of the site.
If your site has documented dead zones and no backup communication, your duty of care has a gap. SiteTalkie closes that gap — for less than the cost of a cup of tea per worker per month.
