Want to upgrade your concrete structure but don’t have as-built structural drawings?
Non-destructive and minimally invasive concrete field testing can determine the health of your concrete structure and predict its useful remaining life. It can also determine or verify the reinforcement in your concrete structure. Non-destructive testing can also be used to determine the actual concrete compressive strength which supports as-built analysis and determination of reserve load carrying capacity.
Corrosion is reinforced concrete’s number one enemy. Corrosion is the result of an electrochemical reaction among ferrous metal, water, and oxygen where rust or other corrosion is formed. This rust expands 5 to 7 times its original volume, and there is no stopping it.
Initial Non-Destructive Testing (NDT) recommended:
- Visual Examination: to identify wood and concrete deterioration, efflorescence, and leaks.
- Probes: to identify soft spots requiring further investigation. Crack gauge to determine crack width and identify which cracks need to be sealed or epoxied (glued) back together.
- Hammer and Rotary Hammer Testing (sounding): to identify delamination and future spalls on horizontal and vertical concrete surfaces.
- Electrical Resistivity: to identify the presence of a corrosive environment (corrosion potential) containing chlorides and moisture penetration.
- Ground Penetrating Radar (GPR): to identify corroded rebar, rebar size, cover, and location. Check for voids behind concrete.
