On cloudy days, Scan Plus is sure to receive phone calls from concerned customers, asking if the rain will delay their utilities being marked. We tell them possibly, because when the clouds open up and the rain pours down, spray paint will run like mascara! Unfortunately, the spray paint will not stick to a wet surface, potentially delaying the utility markings for hours or even days.

We also want to avoid damage to our utility locating equipment, which would result in even more of a job delay. In the case of a thunder and lightning storm, we often seek shelter and wait up to 45 minutes from the last lightning strike before returning to the job for the safety of our technicians.

Did you ever park on the street or walk on the sidewalk and noticed different colour markings on the concrete and wondered what that’s all about?

Well, let’s start by understanding first what each color stands for as for the reason behind it all….

Companies with underground networks have agreed to a color code to identify the type of network buried. Each member company marks the precise location of its network using color as shown:

Scan Plus continues to see an increase in the use of ground penetrating radar to scan or image concrete slabs. Concrete imaging with ground penetrating radar is typically a very successful process yield results that ensure construction, cutting, drilling, etc. can continue without impact to the facility or project.

1. Often we are asked if Ground Penetrating Radar (GPR) can scan/image concrete slab-on-grade. The answer, simply, is yes. This question often comes from someone who is familiar with concrete “X-Raying”. While X-Raying concrete is still a valid technique for determining the location of reinforcing steel it is limited to elevated concrete slabs only. This is because you need to have access to both sides of the concrete to perform an x-ray. Ground penetrating radar is a completely different technology.

Here’s 5 reasons why:

# 5. The schedule:

Every project struggles to maintain its projected schedule. One of the biggest problems are the unexpected. This could be because a utility is cut or damaged during excavation, or an electrical conduit was severed while cutting the concrete slab. Scan Plus can help you keep your project on schedule …

We help by mapping the various ducts found in a slab or in private or public outdoor area. These findings can be sketched, mapped, plotted and reported in many different ways.

Don’t worry – it’s not some sort of disease or infection… a “UST” is an Underground Storage Tank. A UST is any tank, including the underground piping connected to it, with at least 10% of its volume underground.
