TYPE OF MATERIAL
SealBoss
® 1640 SlabLifter (TM) & Water Plug Foam
is a
closed cell, two-component, non-shrink polyurethane foam with
structural properties. This MDI (methylene-diphenyl-isocyanate) based
product is 100% solvent free and 100% solids. The product starts to
react when mixed and does not need moisture from external sources
for the reaction. The cured foam offers limited structural strength
combined with increase in volume and excellent bonding properties on
dry and with limitations on wet surfaces. The product is not a
replacement for typical epoxy injection but offers an alternative for
filling larger spaces that demand limited structural strength. The
compressive strength of the reacted product is typically much higher
when filled with an inert mineral such as sand.
SealBoss
® 1640 SlabLifter (TM) & Water Plug Foam
is
designed to fill voids in soil and stone, brick or concrete structures for
the purpose of waterproofing as well as regaining certain structural
strength. The excellent combination of hardness and flexibility qualifies
SealBoss
® 1640 SlabLifter (TM) & Water Plug Foam
for use in
areas where structural strength and moderate flexibility are desired.
SealBoss
® 1640 SlabLifter (TM) & Water Plug Foam
is an
excellent soil solidification foam which can be used to seal, lift, fill and
densify soil next to and under structures such as roadways, driveways,
runways, patios and other buildings by utilizing a deep grout injection
process.
The expanding and compressive strength qualities of
SSealBoss
® 1640
SlabLifter (TM) & Water Plug Foam
make it a price
competitive alternative for the filling of large voids and 'pockets'. The
structural strength of the foam product is highly correlated to the
expansion rate and the use of inert fillers such as sand. On the job
testing may be neccessary to determine the suitability.
SealBoss ®
1640
SlabLifter (TM) & Water Plug Foam
is a polyurethane foam
that increases its volume up to eight times in its original formulation,
forming a closed cell structure. The 600% to 800% increase in volume
cuts down the material consumption drastically.
SealBoss ® 1640
SlabLifter
(TM) & Water Plug Foam
can be applied in dry and wet
areas. Additional moisture may increase the expansion. The standard
mixture expands approximately six times in volume. For larger orders
the material can be custom designed to allow more or less expansion
and to increase or decrease the gel time. To achieve most satisfying
and permanent results in certain applications, a commbination of
SealBoss
® 1640 SlabLifter (TM) & Water Plug Foam
with other
systems of our product line may be advised. Ask your
SealBoss
technician for details.
SealBoss
® 1640 SlabLifter (TM) & Water Plug Foam
is not
designed to stop high velocity water leaks. To stop active water leaks
please refer to
SealBoss ® 1510 Water-Stop-Foam.
PROCESSING
SealBoss
® 1640 SlabLifter (TM) & Water Plug Foam
is a preadjusted
two-component foam system.
The mixing ratio is 1:1 (A:B) by volume. At room temperature the
pot life is approximately five to eight minutes. The expansion process
will last for approximately twenty minutes. The material will be completely
cured after sixteen hours.
Due to the short gel time, dual-component equipment is deemed
mandatory for injection. In some cases the product may be poured.
Independant of the application procedure, the components need to be
thoroughly mixed either in a container prior to the application or by the
use of a static mix head just before the injection.
It is essential for all equipment to be dry. Avoid any moisture
contact with the mixture to prevent premature reaction of the product.
If reaction of the batch occurs while pumping, immediately shut down
the machine and flush as recommended below to avoid built up and
clogging of the equipment.
MAINTENANCE OF EQUIPMENT
Remove all excess product and any smears. Tools and mixing
equipment must be cleaned immediately after use.
R70 Pump Flush
is good to your equipment and should always be used. For best results
please follow our recommendations.
First Step
is conditional - Omit if in conflict with regulations on the
jobsite or the equipment you use: Flush first with a very small amount
of solvent (not supplied by us) to cut remaining material. Caution: Xylol,
Toluol, Acetone, M.E.K. are hazardous, combustible, aggressive
towards the environment, equipment, seals and hoses. Immediately
follow second step.
Second Step:
Flush with R70 Pump Flush circulate cleaner
through pump and hoses for several minutes at higher flow rates.
R70
Pump Flush
is a solvent free, non-flammable cleaner, lubricator and
pump and hose conditioner. The product ships without any hazard
label. We assumes no responsibility for equipment damaged by use of
material.
PRECAUTION
Protect your health! While working with this material, safety
goggles, gloves and safety clothing must be worn at all times. While
injecting, a full face shield is strongly recommended. Spills and blowouts
do happen! Protect yourself and others on the jobsite. Consider
property in proximity of the application area to prevent loss or damage.
Protect your jobsite from unauthorized persons. Store all materials and
equipment safely and out of reach of children!
Observe container labels, MSDS, and instructions in the Product
Catalog before using the product and equipment. In case one of the
components comes in contact with the skin, wash thoroughly with
soap and water. Provide adequate ventilation in volume and pattern in
working area. Further protection: emergency showers and eyewash
stations.
