PARAS is a secure and speedy way to assess sub-structure foundations.
Designed to check the depth and integrity of concrete, masonry, or steel foundations considered to be inaccessible or where other non-destructive methods are of little use; PARAS offers an alternative testing method conventional pile testing techniques may be inappropriate. The test requires an access tube to be installed parallel to the pile or sheet piling to be tested.
The PARAS system measures the time taken for a signal to travel from a hammer impact point to a hydrophone transducer as it is lowered down the access tube. A change in the signal arrival time indicates the depth of the foundation. Housed in a rugged plastic case with high-quality waterproof connectors, this lightweight and portable signal acquisition and analysis unit are designed to test in all weathers.
