Products

CarboStop R 402 is a water-reactive, one-component resin characterized by
high flexibility and elasticity. To accelerate the reaction, CarboStop 402
ACC is added. Once cured, the material forms a foam with a high percentage
of closed cells in its compacted state.

Viscosity at 20°C

970 ± 50 MPa·s

With the addition of ACC

adjustable reaction time (from 3.5 to 11 min)

Applications

► Stopping water ingress (including saltwater) under high pressure
► Stabilization and waterproofing of fractured or deteriorated rock
formations
► Crack injection and joint sealing
► Waterproofing of expansion joints and movement (temperature) joints

Component Description

CarboStop R 402 is a resin composed of modified isocyanates and additives.

CarboStop R 402 ACC is a catalyst blend used to adjust and control the
reaction rate.

Key Advantages

► Wide range of applications
► Self-sealing properties that do not damage the structure
► Adjustable reactivity of the injection mixture
► The prepared reaction mixture can be stored for at least 48 hours
without a noticeable increase in viscosity, provided that exposure to
humid air is prevented.

Operating Principle

Before use, a sufficient amount of CarboStop 402 ACC is added to CarboStop
402 resin to adjust the reactivity of the injection mixture according to
site conditions.

CarboStop 402 / CarboStop 402 ACC is injected into water-bearing areas
through a packer (injector) as a single-component material using a manual,
electric, or pneumatic pump. Upon contact with water, the reaction mixture
expands significantly and cures into a solid foam.

Packaging

CarboStop R 402 – 20 kg canister.

CarboStop 402 ACC – 1 kg plastic bottle.

Storage

Shelf life: 12 months from the date of manufacture when stored in a dry
place.

Recommendations

Before use, the resin must be conditioned for at least 24 hours at a
temperature of no less than +20°C.

Localized overheating of the canister walls must be avoided.

If the area to be sealed contains insufficient water, complete curing of
the resin can be achieved through pre-injection or post-injection of
water.

Equipment

Compact single-component or two-component injection pumps with manual,
pneumatic, or electric drive, along with injection accessories such as
packers/sealing packers, injection and discharge hoses, shut-off valves,
nipples, coupling fittings, and clamps.
