Sandberg Remains Open During This Challenging Time

Whilst many of our staff are working from home during these unprecedented times, all our activities remain open for business in line with government guidelines.  We have adjusted our operations so that staff remain safe.  Currently, although we are working at a reduced capacity, we are meeting client demands and are welcoming new enquiries.

Ground Penetrating Radar

Ground Penetrating Radar (also known as Ground Radar, GPR, Impulse Radar Ground Probing Radar, Sub-surface Radar and Surface Penetrating Radar) was originally developed for mapping geological features. It is now increasingly used as an NDT survey technique in Civil Engineering and offers a unique non-invasive and non-destructive means for the characterisation of the subsurface and subsurface features.

Interested to understand how Ground Penetrating radar works? Did you know that using antennas with different central frequencies affect the penetration depth and resolution? Find out more about GPR; a flexible, non-intrusive and non-destructive technique for the investigation and characterisation of the sub surface.

Ground Penetrating Radar (GPR) offers a cost-effective non-destructive (ND) method of building inspection and investigation. GPR can be used to determine construction detail when no as built drawings are available (or to confirm that drawings that are available are correct) and assessing the feasibility of proposed building works.

Ground Penetrating Radar (GPR) is very effective in locating chimney flues in buildings. This can be done with no intrusive works or damage to the building structure. It can be done in occupied buildings with minimum disruption to the occupants. The only requirement is that good access to the walls to be surveyed is available.

Ground penetrating radar (GPR) is regularly applied to examine concrete structures such as walls, floors, columns and bridges. It has recently gained popularity for concrete imaging. GPR’s advantages over more traditional methods such as covermeter and Ferroscan are many...

Modern concrete floor slabs can be subjected to extremely tough conditions including heavy static and moving loads, impact and abrasion . Warehouse floors in particular can suffer badly. Problems with concrete floors can also arise when a change of use occurs and loads differ from the original design. Failure of the concrete floor slab may occur, resulting in costly down time and expensive repairs.

Ferroscan and Ground Penetrating Radar (GPR) both offer an effective means of reinforcement detection and imaging within concrete. Sandberg can undertake detailed reinforced concrete investigation and rebar mapping using either Ferroscan or GPR; but which method is better? What are the differences?
