PUR-Injection Foam for Water Stopping

1. Product profile :
Tobust Injuction SPU 10 is fast foaming and solvent-free
water-reactive polyurethane injection foam resin, which
cures to a dense flexible foam with a fine cellular structure.
Suitable for for stopping rapid water flow and ground
stabilization.
TOBUST INJECTION SPU 10
PUR-Injection Foam for Water Stopping
.
PROPERTY PROFILE
 Repair of concrete structures
 Void filling
 Stabilization of fractured rock, sands
and gravels, and land-fill materials
 Stopping of high water intrusions in
cracks, joints and cavities in concrete,
brickwork and natural stonework.
 Control of high volume water ingress
UNIQUE FEATURES
 When in contact with water, the product
forms a rigid foam. In the absence of
water, the product reacts and forms a
stiff, rubber-like material
 No reaction takes place unless it is in
direct contact with water
 Fast-reacting material where structural
strength or rigidity is required
 The reaction speed (foam formation) is
influenced by the temperatures of the
mixed material, the structure and the
contact water, plus the hydrodynamic
conditions.

Important: By single action piston pump operating at high
pressure. By twin piston pump when mixed with water
(100:15) to produce foams of different densities. Sealing
cracks(minimum crack width 0.2mm,for smaller cracks
consult Tobslak technical department). Drill 15-22 mm
holes along the side of the crack at 45° angle. Drill the holes
to intersect the crack midway. Install injection packers in
the holes and tighten. If the cracks to be injected are 10mm
wide or more at the surface, pack open cell polyurethane
foam saturated with Tobust Injuction SPU 10 into the crack.
Spray the saturated foam with a small amount of water to
activate the grout and create a surface seal. Pump Tobust
Injuction SPU 10 at >20 bar into or behind fissures or into
voids which are allowing water to infiltrate into unwanted
areas. If voids in concrete being injected contain insufficient
moisture to activate the grout inject a small amount of
water prior to injecting the grout. Pump Tobust Injuction
SPU 10 for approximately 15 seconds and then pause to
allow the material flow into all the cracks and crevices.
Keep pumping, watch for material flow and water to appear
at the surface or the next packer. When movement stops or
Tobust Injuction SPU 10 appears at the next packer move
to the next packer and inject. When sealing vertical cracks
start at the bottom and work upward .
