When planning M&E containment runs for cabling, pipework, or ducting, precision is everything. Creating accurate service routes through reinforced concrete and structural elements is one of the most time-consuming tasks in building services installation. That’s where diamond drilling provides a clear advantage. Its ability to produce precise, clean openings with minimal disruption makes it the preferred choice for mechanical and electrical contractors working on both new-build and live building projects.
In this article, we’ll explore how diamond drilling enables efficient M&E containment runs, reduces on-site delays, and supports faster, cleaner, and safer installations.


What Are M&E Containment Runs?
In modern construction, containment runs are the pre-planned routes that carry electrical, mechanical, and communication systems throughout a building.
They may include:
- Electrical conduits and trunking
- Cable trays and basket runs
- HVAC ducting and ventilation shafts
- Plumbing and fire protection pipework
Each route must be carefully coordinated to avoid clashes with structural reinforcement and other building elements.
Creating these service paths efficiently requires accurate drilling techniques that maintain structural integrity and avoid costly rework.

Why Diamond Drilling Is Ideal for Service Route Creation
Diamond drilling offers unmatched precision, control, and flexibility for forming penetrations along M&E containment routes.
Key advantages include:
- Accuracy: Drills perfectly aligned openings for conduits, trays, and risers.
- Low vibration: Prevents cracking or damage to surrounding concrete and finishes.
- Minimal noise and dust: Keeps worksites clean and operational, even in occupied buildings.
- Versatility: Suitable for horizontal, vertical, or angled drilling.
- Speed: Faster and cleaner than percussion or hammer drilling methods.
For M&E contractors, these benefits translate to shorter installation times, fewer errors, and greater safety compliance.
How Diamond Drilling Supports Efficient
M&E Containment Runs
Precision Openings for Conduits and Cable Routes
Diamond drilling is used to create perfectly sized holes that align with containment layouts and cable trays. This ensures straight, consistent routing through structural elements, which is critical for large installations across multiple floors.
Controlled Drilling Through Reinforced Concrete
Because diamond-tipped cores can safely cut through reinforcement, contractors can maintain containment runs without redirecting routes unnecessarily, saving time and material costs.
Creating Riser and Core Holes
Large-diameter diamond cores are ideal for vertical risers, allowing electrical and mechanical systems to pass between levels. These openings can be drilled to exact dimensions, providing smooth containment paths without chipping or overbreak.
Working in Live Buildings
In occupied environments, diamond drilling’s low-noise, low-vibration operation allows teams to form new service routes without disrupting daily operations. This is particularly beneficial in offices, hospitals, and residential refurbishments where maintaining normal use is essential.
Health, Safety & Compliance
All diamond drilling operations for service route creation should comply with strict site and regulatory standards, including:
- CSCS and SSSTS certification for operatives
- RAMS (Risk Assessments & Method Statements) specific to M&E works
- Dust and water control under HSE and COSHH guidance
- Adherence to BS EN 206 for concrete works and structural integrity
At PCDD, every project is carried out with full consideration of safety, environmental protection, and site coordination.
Best Practices for M&E Contractors
To maximise the efficiency of containment installations using diamond drilling, contractors should follow several key practices:
Plan containment routes early
Coordinate drilling locations with structural drawings and other services
Apply correct feed pressure and water cooling
Ensures smooth cuts and prevents overheating.
Use GPR scanning
Identify reinforcement and embedded services before drilling.
Implement dust and water control
Use vacuum systems or suppression for clean, compliant working conditions.
Maintain clear communication
Coordinate with main contractors to avoid clashes or duplicate penetrations.
Following these practices keeps M&E works on programme, compliant with safety standards, and free from unnecessary rework.
Case Study Example
During a commercial office fit-out in central London, PCDD was engaged to create a series of core holes to establish new containment routes for electrical and HVAC services.
Using diamond drilling rigs, the team formed precise openings for risers and conduit penetrations across multiple floors, completing the work with zero disruption to adjacent tenants and no structural damage. This approach allowed M&E contractors to install containment swiftly, maintaining the tight project timeline.
Can diamond drilling be used for both small and large containment routes?
Yes, from 10 mm holes for conduits to 1,000 mm cores for major risers or ducting.
Does diamond drilling damage reinforcement?
No. It can safely cut through rebar without weakening the structure when performed correctly.
Is diamond drilling suitable for occupied buildings?
Absolutely. Its quiet and vibration-free process makes it ideal for live environments.
Can drilling be done overhead or at angles?
Yes. Diamond drilling rigs can operate vertically, horizontally, or at any required angle.
Diamond drilling is an essential tool for creating efficient M&E containment runs, ensuring precision, safety, and minimal disruption on any project. By combining advanced drilling techniques with expert planning and site coordination, PCDD helps M&E contractors form accurate service routes through concrete and structural elements safely and on time.
