Ground penetrating radar (GPR) concrete scanning is one of the most powerful non-destructive investigation tools available to the construction industry. Unlike ferro scanning — which is specifically tuned to detect steel — GPR can detect almost anything embedded within or beneath a concrete structure. This guide explains how GPR works, what it finds, and the […]

Working on or near the operational railway — whether on structures, tunnels, bridges, station platforms or track-side infrastructure — requires a level of approval, competency and process compliance that goes significantly beyond standard commercial construction. Principal contractors and specialist subcontractors working on Network Rail infrastructure must understand what approvals are required and how to demonstrate […]

Ground penetrating radar (GPR) uses pulses of electromagnetic energy to detect and map objects buried within concrete, soil and other materials. In construction it has become an essential tool for pre-works surveys, structural investigation and utility detection — providing information about what lies beneath the surface that cannot be obtained by any other non-destructive method. […]

Core drilling into reinforced concrete is one of the most common tasks in construction — creating penetrations for pipes, cables, drainage, and M&E services. It looks straightforward. But drilling blind into a concrete slab or wall without knowing what’s inside is one of the most avoidable sources of programme delays, structural damage, and serious safety […]

Fire door inspection has moved from best practice to legal requirement following the Fire Safety Act 2021 and Fire Safety (England) Regulations 2022. Building managers and responsible persons need to understand what is required and what constitutes a compliant fire door. What the Regulations Require The Fire Safety (England) Regulations 2022 introduced mandatory fire door […]

On complex projects or in sensitive structures, the quality of the diamond drilling contractor matters enormously. Here’s what to look for when selecting a specialist. Accreditations A credible contractor should hold CHAS (or equivalent SSIP pre-qualification), ConstructionLine registration, and adequate public liability insurance. For any work on or near the railway, Network Rail approval is […]

Structural works on existing reinforced concrete buildings — creating new openings, installing post-installed fixings, adding service penetrations or carrying out demolition — all carry the same fundamental risk: the contents of the concrete are invisible until you cut into it. Understanding what scanning can and can’t tell you is essential to protecting the structure and […]

Stitch drilling — sometimes called stitch coring — is the method used to create openings in reinforced concrete that are too large for a single core bit. By drilling a series of overlapping holes in a defined pattern, any size or shape of opening can be created with no vibration shock to the surrounding structure. […]

Robotic demolition uses remote-controlled, electrically powered demolition machines to carry out breaking and demolition in environments where conventional methods are impractical, unsafe or impossible. It has become an important capability for specialist contractors working in confined spaces, high-risk environments and live buildings. How Do Robotic Demolition Machines Work? Robotic demolition machines are compact, tracked, remote-controlled […]

Wire sawing and flat sawing are both diamond cutting methods for reinforced concrete — but they work differently, suit different applications, and have different depth capabilities. Choosing the wrong method means either a job that can’t be completed or a more expensive approach than necessary. What Is Flat Sawing? Flat sawing uses a large circular […]
