ULTRALITE Pads Brochure

FEATURES & BENEFITS
LIGHTWEIGHT At an average weight of
2-1/2 pounds per square foot (12 kg. per square metre),
the UltraLite lightweight concrete pad is one of the lightest
equipment mounting products available today. Lightweight
products are important for ease of handling on job site.
DURABLE The exterior of the UltraLite lightweight
concrete pad is specifi cally engineered for long-term exterior
weather resistance.
DUCTILE The skin and core of the UltraLite light-
weight concrete pad is specifi cally engineered for fl exibility
and ductility demanded of job site handling. Additionally, the
ductility of the outer skin facilitates conformance to slight
ground contours without fracture.
TIME/LABOR SAVINGS Time is money,
and hence any time savings on site translates into money saved.
The UltraLite lightweight concrete pad literally installs in seconds
while providing a solid foundation for the condensing unit.
CONCRETE SURFACE The concrete
external skin of the UltraLite lightweight concrete pad is not
subject to ultraviolet degradation or weathering discoloration.
LOADING
To achieve the maximum permissible pad load capacity,
the earth under the pad must be capable of supporting the
transmitted compression load of the UltraLite pad. All
values tabulated assume the earth has a bearing capacity
of at least 1000 pounds per square foot (48 kPa).
The allowable loads assume a uniformly distributed loading
on the pad surface (that is, a relatively fl at-bottomed
condenser unit in contact with the pad). For condenser
units with footpads or other point loads, the maximum
concentrated load for any size UltraLite pad is 125 pounds
per 2” (56 kg per 50 mm) diameter (or equivalent surface
area) footpad.
TECHNICAL DATA
UltraLite Pads are made by DiversiTech, North America’s largest manufacturer of equipment pads.
FREEZE/THAW TESTING
The UltraLite pad has been independently tested to the
rigorous freeze-thaw regimen specifi ed by ASTM C67. This
standard dictates a twenty-fi ve cycle freeze-thaw sequence.
The freeze portion of the sequence takes place with the top
surface of the UltraLite pad under 1/2” (12 mm) of water.
Once twenty-fi ve cycles are complete, the pad is examined
using visual magnifi cation. No cracks or
crazing is permitted. UltraLite has
performed fl awlessly.
CHEMICAL RESISTANCE
In normal usage conditions an equipment pad can be exposed
to a variety of chemicals. The UltraLite pad has been fully
tested in accordance with ASTM D2299 for resistance against:
• R-22 and R-134a
• Compressor oil
• Salt solution, 20 percent by volume
• Synthetic canine urine
The UltraLite pad performs extra-
or dinarily well under these testing
criteria. UltraLite does not craze,
soften, delaminate, or spall under
exposure in this test.
VIBRATION ABSORBING The
engineered polystyrene core to the UltraLite lightweight
concrete pad absorbs and dampens vibration associated
with normal operation of a condensing unit.
FREEZE/THAW RESISTANT
The UltraLite lightweight
concrete pad is vapor
permeable. Water vapor
evaporates through the
pad, hence the concrete
outer skin is not subject
to expansion cracks.
FLAME
RESISTANT
The concrete outer skin
of the UltraLite lightweight
concrete pad is resistant to heating caused by the com-
pressor. Additionally, the surface is resistant to heat from
incidental torch fl ame during site installation.
OUTSIDE STORAGE The UltraLite
lightweight concrete pad is intended for life in the outdoors.
As such, the pad is suitable for exterior storage prior to
site installation.
