Overview
UltraLite® is strengthened by miles of fiber in each square foot of fiber-cement coating. This fiber allows the pad to flex instead of cracking or breaking. The textured surface prevents the condensing unit or portable generator from sliding, and allows water drainage, while the engineered encapsulated polystyrene (EPS) core prevents warping and provides a solid bottom to resist settling. The pad is unaffected by soil conditions, ultraviolet (UV) light, temperature extremes, and other weather conditions.
The 2" thick UltraLite® pad is the industry standard. It is used across a wide variety of applications, unless a thicker pad (3") is required by the local building code.
Features
- 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 sites.
- Durable - The exterior of the UltraLite lightweight
concrete pad is specifically engineered for long-term exterior
weather resistance.
- Ductile - The skin and core of the UltraLite lightweight concrete pad is specifically engineered for flexibility
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.
- Vibration Absorbing - The engineered
polystyrene core in 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 compressor. Additionally, the surface
is resistant to heat from incidental torch flame 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.
Technical Data
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 flat-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.
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 extraordinarily well under these testing criteria. UltraLite does not craze, soften, delaminate, or spall under exposure in these tests.
FREEZE/THAW TESTING
The UltraLite pad has been independently tested to the
rigorous freeze-thaw regimen specified by ASTM C67. This
standard dictates a twenty-five 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-five cycles are complete, the pad is examined
using visual magnification. No cracks or crazing is permitted.
UltraLite has performed flawlessly.
