Ground penetrating radar (GPR) technology is a widely accepted method used to detect voids. It is critical to detect voids as soon as possible, prior to any sort of failure. At Echo GPR, we can see these issues at depth and near the surface. Our technology can provide an approximate footprint of what is underneath the surface.
Why Do Voids Occur?
Voids can happen beneath the surface for various reasons. Common reasons include:
- Ground settling/shifting
- Washouts
- Sinkholes
- Long term water/drainage leaks.
- Proximity to water sources (river)
- Historic mining
There are also other types from previous construction that may be present. These could include pipes, quarries, underground tanks, tunnels, or basements.
We Can Detect Voids Beneath Many Surfaces
Detecting voids is helpful across all industries and property types to prevent significant issues or surprises. Echo GPR can investigate the extent of potential problem areas. We can use our GPR technology to detect voids or delamination within concrete, as well as asphalt. We regularly investigate interior and exteriors of existing buildings. Echo GPR has scanned countless commercial and private residences.
Voids in Concrete
If there is a void underneath concrete, it could eventually lead to problems. The problems could get severe enough to where the slab could fail and cause a hole to appear at the surface. This could pose a danger for anyone in or near an area with a void underneath. In an industrial setting, this could cause equipment of vehicles to fall through the surface.
Voids in concrete can happen for various reasons, including:
- Settlement
- Erosion
- Age
- Excess moisture saturation
- Delamination
- Water main breaks
If you have a concern, such as seeing cracks, sagging, or other anomalies at the surface, the team at Echo GPR can help. We can use our GPR technology to scan accessible areas and determine the extent of potential damage below surface. Not only can we detect voids, but we can also possibly estimate volume and determine the extent of the damage.. This is dependent on the surface conditions. This way, you can make the needed fixes before a larger issue occurs.
Voids Under Asphalt
If voids develop under roadways or other commonly used concrete or pavement, it could cause failure. Voids in asphalt typically develop because of erosion at the base of the material. Broken storm or water drains, washout from rains, sinkholes, and other variables can also cause voids beneath asphalt.
Once a void begins, it grows until it gets to a level where its load-bearing capacity significantly lowers. Detecting potential voids in the concrete as soon as possible is crucial. It is hazardous for people to drive and walk on concrete that is in a vulnerable state. Investigating the surface with GPR technology can help to ensure the roadways and other areas of traffic are safe.
Voids Underground
If you’re breaking ground on a plot of land, checking for voids beneath the ground can help significantly save time and costly incidences
When building on any new piece of land, we recommend having us check the area for voids or other potential unknowns using our GPR technology. This is a non-invasive way to investigate any potential issues before you start your project.
