Volumetric Readings
R-Solutions System
1 vs. Poly-urea
Reported herein are the results made in our laboratory on
the material described above,
all tests were performed in accordance with the procedures
outlined in test data below,
at a ratio of 100% of component A, and 100% of component B,
with an ambient temperature of 73 F, and 55% H for R-Solutions
System 1, and at ratio of 1:1, and for the poly-urea product
it is 2:1.
SCOPE
To determine the amount of material that is required
to fill a 4’’ in length and 1 ½”
in width drilled spike hole.
METHOD
An 8-foot railroad tie was prepared for foam placement
by drilling eight (8) three-quarter-inch square holes to a
depth of 4 inches. After drilling the tie holes, they were
cleaned out by the rolling tie over and removing all latency
within the hole.
TEST PROCEDURE
At the beginning of the test each product is placed in a vessel
and weighed to 200 grams and 100 grams. After the material
has been mixed and weighed it is then dispersed into the prepared
hole. The product in each of the systems was placed in the
hole until the hole was filled and the material was flush
with the wood substrate careful not to over fill. After the
material was placed the products were weighed again to determine
how much product was used per hole.

Product Usage Comparison
* Total mean usage for Poly-urea is 149.62 grams per hole.
* Total mean usage for System 1 is 44.12 grams per hole.
Holes Filled Comparison
* Total tie holes filled per gallon of Poly-urea is approximately
311.
* Total tie holes filled per gallon of R-Solutions System
1 is approximately 700.
CONCLUSION
The usage rate of material to fill and repair a standard
tie hole with the R-Solutions System 1 Polyurethane Foam is
12 grams per hole. The usage rate of material to fill and
repair a standard tie hole with Poly-urea is 35 grams per
hole. The amount of R-Solutions
System 1 material that is required to fill and repair a standard
tie hole is 200% less than that of Poly-urea.
Because of R-Solutions System 1 ability to foam and rise in
a constricted area, less material is needed to perform the
repair.
