Technical Information
Description
PolyLEVEL
®
100-SS is a low viscosity,
polyurethane resin designed to penetrate and
stabilize loose or sandy soil when medium or high
strength is required. It migrates through loose soil
and into voids and reacts with moisture in the
soil to form a polymer cement/soil matrix of high
strength and durability. PolyLEVEL
®
100-SS is
resistant to most organic solvents, mild acids and
bases, and micro-organisms. The polyurethane
encapsulates loose soil, fills voids, and forms a
solid, water-tight barrier.
Unique Advantages
• Contains no solvents
• Very low viscosity for good penetration
• Fast cure time controlled by catalyst ratio and
moisture in the treated soil
• Encapsulates and strengthens loose soil
• Forms a water-tight barrier to stop water
migration
• Good resistance to chemicals
• Excellent compressive strength (over 1,000
psi in sand) and thermal stability

Storage and Cleanup
Activator MUST be agitated (shaken) before use.
Flush equipment with acetone before and after
use to clean equipment and remove moisture.
If work area temperatures are low, heat the
product to 55°F - 85°F to improve product
performance. Do not use open flame as a heat
source. Store chemicals between 55°F - 85°F
in a dry atmosphere. Shelf life is 6 months, in
original, unopened factory containers, under
normal storage conditions of 55° to 85° F. Do
not store in direct sunlight. Keep drums tightly
closed when not in use. Cured product may be
disposed of without restriction. Excess liquid
material should be mixed together with sand or
other absorbent material and allowed to cure,
then disposed of in the normal manner.
Safe Handling of Liquid Components
Use caution in removing caps and bungs from the
container. Loosen caps and bungs first to let any
built up gas escape before completely removing.
Avoid prolonged breathing of vapors. In case of
chemical contact with eyes, flush with water for
at least 15 minutes and get medical attention.

Caution
Polyurethane products manufactured or
produced from this liquid system may present a
serious fire hazard if improperly used or allowed
to remain exposed or unprotected. The character
and magnitude of any such hazard will depend
on a broad range of factors which are controlled
and influenced by the manufacturing and
