ASI is established as a leading company in modern
testing of foundations and materials. At its disposal is an arsenal
of testing systems and equipment using the latest technology in sonic wave
applications, data acquisition electronics and software, combined with a
solid team of experienced engineers and researchers.
- Dynamic testing of foundation piles
-
Dynamic testing is a
versatile test for pile capacity, performance of the driving system,
and pile integrity. It is gaining wide acceptance in North America and
overseas, as an alternative to expensive and time-consuming static
loading tests. The procedure for this test is also explained in ASTM
Standard D4945-00
- Static loading tests of foundation
piles
-
Traditionally, static
loading was the most common way of testing pile foundations. There are
several accepted procedures to set-up and perform a static loading
test, which are explained in detail in ASTM Standard
D1143. Recently, another form of static testing, the
Osterberg Cell (O-CellTM) testing, is
becoming a very popular method for testing drilled shafts.
- Low-Strain Pile Integrity Testing (PIT) or
Sonic Echo testing
-
This non-destructive
testing method is one of the most versatile means of quality assurance
when it comes to cast-in-place concrete foundations. It is fast,
inexpensive, and completely portable.
- Crosshole Sonic Logging (CSL)
-
This state-of-the-art
testing method uses the sonic wave propagation theory to check the
material quality and integrity of newly placed drilled shafts, seal
footings and slurry or diaphragm walls, and other structures. This
method is gaining popularity in the industry for its versatility and
reliability.
