High Density GPR Survey

Single channel Ground Penetrating Radar (GPR) is currently used across the UK to locate buried utilities on construction sites.

However, it's not just the buried utilities that affect the design process and cost money. It's also the other buried obstructions. For example, voids, culverts, foundations and even tree roots, which standard GPR won't always find. That’s where SUMO's new high density multi-channel radar comes in.

SUMO can locate all of these obstructions in a single pass, giving you: -

Improved Resolution: 8 channels of data at 8cm spacing with 12x better resolution than a standard utility radar survey.

Improved Speed And Efficiency: No need for repeated passes across the survey area. This saves time and causes less disruption to your site.

Improved Data Display: Instant 3D pictures can be produced on site.

Improved Accuracy: Tracked by the latest land survey technology for precise topographical positioning.

Example: Tree Root Survey

High density radar survey of tree roots

SUMO created the following 3D image from data collected by SUMO's new high density multi-channel GPR. It shows the exact location of the tree roots at 0.2m depth:

Using the same technology, an elaborate pattern of forgotten footpaths, flowerbeds and centre-pieces dating from the early Victorian period were revealed. This was just beneath the surface of the front lawns of a former stately home, which is now a public school. Historical records from circa 1880 actually show the layout of the gardens, but by 1906 they had disappeared. Deeper still, there are more features, which could be significantly older. Perhaps the remains of a medieval manor house, which stood on the site before the current building.
