DE NEEF® waterproofing injection solutions
Leaks stop here: Fast, proven, durable.
The DE NEEF® portfolio provides waterproofing injection solutions that stop leaks under any circumstances and in any application--foundations, infrastructure and more. Nobody plans for a leak, so when one occurs it usually represents a cost overrun and a setback for a construction project. The ability to quickly and permanently stop a leak in any part of a construction is therefore invaluable for contractors and owners.

Products
- Product Name
- Description
- Key Benefits
- Applications Type
DE NEEF® HA Cut AF is a next generation 1-component injection resin with improved waterproofing and water cutting performance.
- ADR free transport
- Next generation resin with improved waterproofing performance.
- Improved cell structure of the cured compound resulting in better mechanical properties and durability.
- Used to block water leaks in diaphragm walls.
- Filling large voids
- Injection of LDPE or HDPE membranes in tunnel construction
DENEPOX™ 40 is a pre-weighted two-component epoxy resin, which cures into a rigid compound.
- Insensitive to humidity
- Cures in damp/wet environment
- Low viscosity
- Low pressure injection
- Bonding and anchoring
- Sealing of porous low density concrete
Elastopack 201 is a 2-component, phthalate free, injection grout consisting of a resin and a hardener, which are injected as 1-component system after mixing. After curing, the grout will become a dense and elastic material.
- ADR free transport
- Phthalate free resin, REACH compliant
- Packed as a complete pre-weighted set
- Sealing of moving or non-moving cracks in concrete or masonry structures
- Sealing of dry to moist cracks in concrete or masonry structures
- Sealing of hairline cracks where other resins cannot penetrate
GELACRYL™ TI is a special 3-component poly-acrylate injection resin developed specifically for injection of preventative injection tubes.
- Easy to use 3-component system
- Long gel time allows controlled injections
- Linear viscosity increase
- Injection and re-injection of preventative injection tubes.
HA CUT™ Cat F/XF/SXF AF are red non-flammable, phthalate free liquids for applications in cold temperatures or when use of the standard catalyst does not give a fast enough reaction.
- ADR free transport
- Next generation resin with improved waterproofing performance
- Improved cell structure of the cured compound
- Cutting off gushing leaks with a high to very high flow rate and/or high to very high pressure
- Use in cold to very cold temperatures where fast reaction times are needed
HA CUT CFL AF is a next generation 1- component injection resin with improved waterproofing and water cutting performance.
- ADR free transport.
- Next generation resin with improved waterproofing performance.
- Improved cell structure of the cured compound
- Designed for cutting off gushing water leaks
- Used to block leaks into diaphragm walls.
- Filling large voids
HA FLEX LV AF /Flex SLV AF are next generation 1-component injection resins with improved waterproofing performance.
- ADR free transport.
- Next generation resin with improved waterproofing performance.
- Improved cell structure of the cured compound
- For stopping water leaks through joints between tunnel segments.
- For injection of the LDPE or HDPE membrane in tunnel constructions.
- For curtain injections behind tunnel segments
HA SAFEFOAM™ NF is a single component, phthalate free, low viscosity, hydrophilic, polyurethane resin.
- ADR free transport
- Phthalate free resin, REACH compliant
- Non-flammable
- For sealing dry, moving, non-structural cracks
- For sealing moist, moving non-structural cracks
- For sealing water leaks between the joints of concrete tunnel segments
HA Soil AF is a dark brown, non-flammable, low viscous liquid without phthalate plasticiser that expands and quickly (depending on temperature and the amount of HA Soil Cat AF catalyst used) cures to a rigid polyurethane foam.
- ADR free transport
- Next generation resin with improved performance
- Phthalate-free resins, REACH compliant
- Used for stabilising loose soils or to increase the load bearing capacity of these soils.
Seal leaks almost as fast as they appear
The major advantages of DE NEEF® products include the fact that they are easy to use, are not diluted and can be applied quickly and reliably. The portfolio is mostly based on single-component, closed cell, hydrophobic polyurethanes, which are both durable and lasting. Therefore, leaks that are stopped once will remain stopped. For taking care of leaks that slow down the progress of a job site, endanger the future of a construction, or prevent full use of a building, DE NEEF® has become the world's most trusted brand.
Solutions for every leak
DE NEEF® has a variety of formulations for a number of different applications:
- For owners who need to repair and maintain buildings and infrastructure projects
- For contractors who need to shore up deep foundations during excavation
- For installers and applicators who are charged with specialised leak repair
In every case, there's a DE NEEF® solution that's best-suited for the task at hand—including deep foundations, underground spaces, tunnels, mass rapid transport infrastructure and sewer repair applications.
Solutions for every structure
Concrete or masonry—no matter which type of construction, DE NEEF® can fix the leak. From the ground breaking through completion, DE NEEF® products can be used for soil injections and water control and remediation. DE NEEF® solutions can also be used during excavation or tunnel boring. De Neef® products can be used in every stage of underground construction.
Certified around the globe
We have done extensive testing of DE NEEF® products to ensure that performance claims are backed up in the field. DE NEEF® products have multiple certification levels including CE certification for use in the European Union, and have potable water certifications from around the world.
Supported globally, available locally
No two leaks are exactly the same—the only thing that any two leaks have in common is that they have to be fixed as fast as possible. The DE NEEF® portfolio offers solutions for all possible challenges in leak sealing and soil injections. With local availability, there's no waiting for the product to arrive—DE NEEF® is readily available.
With a global sales and technical support staff, contractors can trust that DE NEEF® solutions will perform. Don't wait for leaks to slow you down—contact GCP today to learn how to use DE NEEF® on your project.
