Delamination Surveys

  At EPR Contracts, we use the GP8800 ground penetrating radar (GPR) system as a key tool within our structural survey and non-destructive testing services. This advanced technology allows our survey teams to accurately locate reinforcement, post-tension cables, ducts and services within concrete structures, even in complex or heavily reinforced environments.

For structural surveys, the GP8800 is used to verify reinforcement layouts, assess structural build-ups, confirm slab thickness, identify unknown or undocumented elements, and support load assessments and alteration design. It is particularly valuable where original drawings are missing or unreliable, providing clarity on how a structure has been constructed before refurbishment, strengthening or change-of-use works.

The GP8800 delivers high-resolution, real-time data, enabling EPR Contracts to provide clear, dependable results that support confident engineering decisions. This reduces risk ahead of intrusive works such as drilling, cutting or coring and helps prevent accidental damage to critical structural elements.

EPR Contracts routinely deploys the GP8800 on refurbishment projects, condition surveys, defect investigations and live operational sites. Surveys are completed efficiently with minimal disruption, preserving the integrity of the structure.

Our findings are clearly interpreted and presented in a practical, construction-focused format, supporting engineers, designers and clients with reliable data for safe design, compliance and long-term asset management.
