Diamond Drilling for EV Charger Installation

July 18, 2025

The rapid rise of electric vehicles (EVs) has brought with it a growing demand for robust and reliable charging infrastructure. 

Installing EV chargers, whether at home, in commercial car parks, or at public charging stations, often requires precise modifications to existing structures. This is where diamond drilling comes in! 

At DP Diamond Drilling, we provide the accurate and controlled drilling needed to create seamless and safe cable routes for EV charger installations, ensuring a tidy finish and minimal disruption.

Precision in EV Charger Installation

EV charger installations involve routing electrical cables through walls, floors, and sometimes even underground. The nature of these high-power cables demands precise openings to ensure safety, prevent damage, and maintain the aesthetic integrity of the property.

Clean and Accurate Cable Routes

Diamond drilling offers the ability to create perfectly sized and smooth holes for EV charging cables. This precision is vital for several reasons: it ensures a snug fit for conduit and cabling, which helps to protect the wiring from damage, and it allows for a neat and professional finish, particularly important in visible areas or domestic settings. Unlike percussive drilling, which can leave jagged edges and cause spalling, diamond drilling produces clean cuts, reducing the need for extensive remedial work and ensuring a tidy installation.

Minimising Structural Impact

When installing EV chargers in existing buildings, it's crucial to minimise any impact on the structural integrity of the property. Diamond drilling is a non-percussive method, meaning it cuts through concrete, brick, and other hard materials with minimal vibration. This significantly reduces the risk of cracks or weakening in surrounding structures. For homeowners, this means less disruption and peace of mind that their property remains sound. For commercial properties, it translates to fewer delays and reduced costs associated with structural repairs.

Key Applications in EV Charger Installation

Our precision drilling services are highly versatile, supporting various aspects of EV charger installation projects.

Wall Penetrations

Most EV charger installations require cables to pass through external or internal walls. Diamond core drilling allows for the creation of perfectly sized holes to accommodate the necessary electrical conduits, ensuring a weather-tight seal and a professional appearance. This is vital for both residential garages and commercial buildings where chargers might be mounted on external walls.

Floor Channels and Slab Openings

For installations in car parks or industrial settings, cables might need to be routed through concrete floors or slabs to reach charging points. Diamond cutting and drilling techniques can create precise channels or openings in these surfaces, allowing for cables to be safely embedded or passed through, often beneath the ground or under a new floor finish. The ability to create a perfectly flat and level surface is particularly important in commercial settings where precision is paramount, such as warehouses requiring smooth surfaces for operations.

Foundations and Underground Services

In some commercial or public charging station installations, cables may need to pass through concrete foundations or connect to underground electrical services. Diamond drilling can facilitate these connections safely and efficiently, ensuring that the necessary infrastructure is in place for robust charging solutions. Always checking for utility plans and using appropriate detection equipment to locate any hidden services is vital to prevent striking underground services like gas pipes or electricity cables.

Benefits for Your EV Charger Project

Using DP Diamond Drilling for your EV charger installation offers several advantages:

Enhanced Safety

Our precise drilling methods help to ensure the long-term safety of the electrical installation. Clean, accurately sized holes reduce stress on cables and conduits, minimising the risk of insulation damage or shorts. Furthermore, our adherence to strict safety protocols, including thorough utility checks before drilling, prevents accidental contact with existing services, which can have serious consequences.

Faster Installation Times

With precise openings created quickly and efficiently, electricians can proceed with cable pulling and charger mounting without delay. This streamlined process saves time and labour costs for the overall installation project. Our commitment to client satisfaction extends beyond the technical execution, with clear communication and realistic timelines for completion.

Minimal Disruption and Cleanliness

Our non-percussive methods mean less noise and vibration, which is particularly beneficial in domestic settings or operational commercial environments. We also implement effective dust and slurry management systems, ensuring a clean working environment throughout the process. This professional approach minimises disruption to daily life or business operations.
