SIR-2000

• DOS based menu system
• GPR Data Collection System by GSSI
• Operates single antenna from 25m cable, powered by a 12V DC battery (no supplied) or power point.
• Able to undertake minimal on site processing
• Filter applications, gain variation and background removal(horizontal averaging)
• Files recorded to internal Hard Drive for download to PC using GSSI Data Transfer freeware
• For more information - GSSI Homepage

SIR-20 (Surveyor System)

• This is the latest of the GSSI GPR Data collection systems capable of collecting from two channels simultaneously in muiltiple collection formats.
• The system is Windows 2000 based and operated from a hardened laptop.
• The system operates from 12V DC Battery (not included)
• Files are recorded oto the laptop hard drive and can be burnt to CD or transferred to PC or external hard drive via USB
• The system comes with the Basic Radar Processing Suite to view and analyse files

1.5 Ghz Antenna

• High Frequency ground coupled antenna providing a high level of subsurface resolution to a depth of approx. 500mm
• Ideal antenna for NDT investigations of concrete structurs, assessment of reinforcement depth/locationg and condition or investigation of bound pavement layers in road construction

900 Mhz

• High resolution antenna designed for applications requiring shallow penetration down to 1 meter, such as void detection, concrete thickness assessment and shallow pipe locates.
• Used for rebar identification on projects where antenna size is not critical or space is not limited
• Void Detection
• Archaeological
• Concrete Infrastructure Evaluation (Rebar & Reinforcement)

400 Mhz

• Ideally suited for shallow, up to 3 meters, engineering and environmental applications
• Locate buried utilities, drums, and underground storage tanks (UST's)
• UST Location
• Archaeological
• Pavement and Ballast Investigation
• Underground Utility Location

200 Mhz

• Similar applications to the 400Mhz however lower frequency allows for frequency penetration up to 9 meters
• Useful for Geotechnical Applications such as locating bed rock, ground water and boulder floaters prior to excavation
• Map landfills, burial trenches and filled-in waste lagoons on environmental site assessment projects

Impact Echo System

• A single source acoustic system used to assess internal condition of concrete or masonry structures
• Operates in the time and frequency domain and can accurately measure slab foundation thicknesses up 1.5m
• Can be used to locate horizontal delaminations or voids and areas of honeycombing in structures, as well as assessing voiding within post tension tendon ducts
• System requires laptop to operate and record data, operations and analysis software provided
