Tower Foundation
Condition Assessment Service
Maintaining the integrity of a steel lattice overhead line is vital to ensure reliability of the electricity transmission network and a key component of the overhead line network is the tower foundation. Whilst considerable time and effort is used to inspect the above
ground steelwork, the costly and time consuming excavation of foundations has meant that this is rarely done.
Therefore, the ability to test the integrity of tower foundations by non-intrusive testing is a valuable tool in determining condition.

BENEFITS
- Non intrusive cost effective test to determine foundation condition
- Utilises two measurement techniques to increase value
of results
- Quantitative measurement to assist in refurbishment
planning
- Identifies tower foundations where excavation work
would be advised
FEATURES
Polarisation Resistance- Proven method for obtaining corrosion rates
- Assesses electrochemical mechanisms associated with corrosion
- Testing method involves measuring potential of each tower leg with reference to a copper sulphate half-cell
Transient Dynamic Response (TDR)- Method involves application of vibration signals through the tower foundation
- Proven method for confirming the integrity of concrete foundations
- Determines the depth of concrete foundations
OVERVIEW
