LandScope has developed a structural investigation service based on impulse radar (GPR) and an array of other complementary non-destructive survey techniques. A radar survey provides an exceptionally effective method of mapping elements of interest within both cast concrete and other structural subjects. High frequency antennae are used to provide high resolution images and measurement both within and beyond structural elements.

LandScope augment the radar solution with other non-destructive (NDT) techniques – including EM cover meter, ultrasonic and resistivity profiling – to ensure a comprehensive and accurate survey solution.

LandScope has recently invested in the Giatec iCOR, offering corrosion evaluation in reinforced concrete using an innovative wireless, non-invasive method. This solution offers significant time savings and allows the condition of reinforcing to be assessed and highlighted without the need for drilling or invasive work.

Survey results may be presented in a range of formats including 2D/3D CAD and 3D parametric modelling.

CONCRETE STRUCTURE INSPECTION

A radar survey provides an effective method of mapping elements of interest within cast concrete structures. High frequency antennae, in conjunction with other NDT equipment, are used to provide high resolution images and measurements both within and beyond the concrete structure to identify structural elements and reinforcing spacing, orientation, cover and diameter.

For large areas multiple antennas can be used as an array for maximum efficiency. This combination of techniques can be used to map; reinforcing elements (e.g. rebar configuration), stitch bars and tie rods, slab thickness and reinforcing cover, voiding and honey-combing within spray cast concrete, ground beams and pile caps, voiding beneath slabs, and structural beams.

STRUCTURAL DEFECT SURVEY

Our structural imaging service utilises the latest radar technology to accurately map out a wide variety of buried and covered features and defects. As a Non-Destructive Testing (NDT) technique it is assured that no damage will be inflicted upon the structure. The signals emitted from the NDT sensors are able to penetrate a wide variety of materials including concrete, stone, tarmac, wood, and many more. There are numerous applications for which non-destructive structural imaging has become invaluable.

PILE CAP MAPPING

LandScope utilises the latest in high density GPR array technology to efficiently collect data over piled concrete floor slabs up to ten times faster than conventional single antenna systems.

Rapid and accurately geo-referenced data collection, combined with in-house rigorous processing methodologies, drastically allows LandScope to time-slice the radar dataset to reveal reinforcement densification often associated with pile cap fixing.

In addition to locating pile caps, the survey will also highlight any potential defects such a voiding, identify back of slab and locate any ducting or anomalous areas worthy of further investigation.

BUILDING INVESTIGATION AND HERITAGE

LandScope offers a variety of non-destructive testing (NDT) tools for use in building inspection and investigation including Ground Penetrating Radar (GPR), Resistivity, Ultrasonic, Electromagnetic and Thermal Imaging.

The non-intrusive methods cause minimal disruption and allow our surveyors and geophysicists to measure thicknesses of walls and floors as well as identify any voiding, reinforcement, metallic fixings, tie pins, flues, ducts and conduits, pile caps and basements as may be required.

INTRUSIVE INVESTIGATION

LandScope in partnership with Nicholls Colton can provide intrusive investigation and laboratory testing to compliment our non-destructive survey techniques, providing a complete solution for the client. This includes concrete testing reports, reinforcing breakout, and coring.

Corrosion evaluation in reinforced concrete has traditionally been performed via intrusive methods by creating a physical connection with the reinforcing and performing a half cell survey. LandScope has developed a non invasive technique to wirelessly evaluate corrosion, removing expensive intrusive surveys and overall time required on site.
