3D GPR road cavity survey system

What is the 3D GPR
System?

Equipment for the measurement of underground structures and facilities by using electromagnetic pulses penetrating through the ground or wall.

System configuration

Integrated operation and analysis SW

3D GPR type

  • High speed survey (vehicle type 3-D GPR)

    • - Quick roadbed survey without traffic control.(15~20Km/h)
    • - By lifting it can be switching between normal drive and survey mode.
    • - Multi channel GPR data can be obtained.

  • Precise survey (portable 3D GPR cart)

    • - Survey no car zone such as sidewalk, narrow path and so on
    • - As GPR car performs survey, precise survey selected cavity suspected area is performed.
    • - Easy to store and to transport makes handy operation.
