found that the polymer did densify the soil under the cap and
around the piles repairing the load bearing capacity of the column.

48. The Jim McKay
Competition Pool
In 2012, management
noticed cracks in the pool
deck after the pool had
been drained for regular
maintenance. After
consulting with engineers it
was discovered that the
original Shotcrete walls of
the pool were designed to
support properly drained
soils. However, the western
wall of the pool was under
the constant hydrostatic
pressure of the saturated
soils that surrounded it.
In order to prevent further
damage, the fire
department was called to
refill the pool. But over the
next two years, pool tiles
continued to loosen from

49. The facility is located
at the lowest elevation
level on the entire
campus. This
subjected it to
groundwater runoff
and increased lateral
earth pressure on the
pool.

Water in the soils were
permeating the pool walls
and weakening the tile
mortar bed.

50. The Solution
Various options were considered to
relieve the pool wall of the hydrostatic
pressure, including:
oAdding permanent groundwater wells
around the building perimeter
oInstalling soil nails
oInjecting cementitious grout
oThe Uretek Deep Injection® process

51. Benefits of the UDI® Process at GMU
Displaced saturated soil without increasing
the load like a cementitious grout
Minimal disturbance compared to other
options
Cost-effective
Fast Results

55. Limited Access
Micropiles
Micro-piles and mini-piles
are particularly useful in
restricted access situations
while offering similar
performance to
conventional piles, with
design loads varying
between 3 to 500 tons.
Micro-piles and mini-piles
are well-adapted to dealing
with structural settlement,
underpinning structures or
supporting new loads in
congested areas, providing
support for excavations in
confined areas and
resistance to uplift and
dynamic loading.
