We. MYTHCON, are considered amongst the most reputed service provider of highly reliable PDA Testing to our widely scattered clients. The provided testing service is applied on pile foundations during construction. Our adroit professionals use advanced equipments and techniques to order to provide this service. Our PDA Testing service is highly demanded by clients across the nation owing to its timely execution, high reliable, economical prices and long life.

Dynamic testing of pile foundations during construction provides an economical means to quantitatively evaluate the static load capacity of the pile. Dynamic pile test can be performed on any type pile, cast-in-place concrete, pre-cast concrete, steel or drilled shaft. Dynamic pile testing can be performed in real time using state-of-the-art dedicated system called the Pile Driving Analyzer (PDA). The dynamic pile testing procedure is based on wave propagation theory. The wave is produced by the impact of hammer used to drive pile or re-strike the pile after it is driven. The information obtained from the re-strike provides information about the load capacity of the pile.

The behaviour of pile is dictated by soil resistance under hammer impact loading. Under static conditions, the pile’s capacity to carry load is derived from static soil frictional resistance forces along the shaft (i.e., skin friction) and under the toe (i.e, end bearing). The PDA analyzes and reports both of these resistances and gives ultimate static load capacity of the pile.

In many cases, PDA can replace the static load test requirements and thus is an economical way to assess pile capacity.

The PDA records top force and velocity results, obtained with a pair of each reusable bolt-on accelerometers and strain transducers. A pair of accelerometers and transducers is attached to two opposite sides of the concrete pile near the top. The accelerometers and transducers are attached to a computer (Pile Driving Analyzer) through a long cable. The top of the pile is struck with falling weight that imparts impact to the pile that in turn generates force and velocity waves in the pile.
