About this file
This is a technical data sheet for SPETEC PUR F400, a hydrophobic closed-cell polyurethane foam injection resin manufactured by Alchatek. The product is a one-component, water-reactive resin designed to shut off water leaks in concrete, brickwork, sewers, foundations, and tunnel segments where movement and settlement may occur. Key applications include sealing water-carrying cracks and joints in tunnel segments, curtain grouting behind tunnel and concrete structures, and injection of water cut-off membranes in tunnels.
The product features low viscosity, shrink-free and flexible cured properties, permanent sealing capability, environmental safety, and NSF/ANSI/CAN 61 certification for drinking water contact. Technical specifications indicate uncured viscosity of ±340 centipoise at 77°F, flash point above 302°F, and density of 1.067 ± 0.005 oz/ft³. Cured properties include tensile strength of 290 psi with approximately 100% elongation at break. The resin requires mixing with either Alchatek Gen Cat or Alchatek Gen Cat Fast accelerator (2-10% by volume) and can be applied using hand, pneumatic, or electric injection pumps at pressures not exceeding 1,500 psi. Reaction times vary by temperature and accelerator type, ranging from 14 to 165 seconds depending on conditions. The product is supplied in 5-gallon pails, 10.5-ounce cartridges in cases of 12, or 4-pack kits, and should be stored between 50-80°F. Alchatek provides a one-year limited warranty against manufacturer defects when the product is used according to published instructions and within shelf life.

TECHNICAL DATA
Advanced Construction Technologies Crack Injection
Description
SPETEC PUR F400 is a solvent and phthalate free, water-reactive, hydropho-bic, closed cell, low viscosity, shrink-free, flexible, one component polyure-thane injection resin designed to shut off water leaks.
Uses
• Shut off water leaks in concrete, brickwork and sewers where movement and settlement may occur.
• Water cut-off of water leaks in foundations such as diaphragm walls, sheet piling and secant piles.
| • | Sealing water-carrying cracks and joints in tunnel segments. |
| • | Curtain grouting behind tunnel, concrete, brickwork and sewer walls. |
| • | Injection of water cut-off membranes and liners in tunnels. |
Advantages
| • | One component. |
| • | Different reaction times are possible by adjusting the percentage of |
Alchatek Gen Cat or Alchatek Gen Cat Fast accelerator.
• The closed-cell structure of cured polyurethane ensures permanent flexible sealing of cracks and joints.
• Cured polyurethane is flexible, shrink-free and exhibits good chemical resistance (contact our Technical Service for chemical resistance).
• Cured polyurethane is harmless for the environment and resistant to biological attacks.
• Certified by ALS Global to NSF/ANSI/CAN 61 (approved for contact with drinking water).

Application
Note: the following are a few typical application descriptions. In case of other jobsite parameters, please contact our technical department.
PRELIMINARY ANALYSIS
For leaking joints, identify if the cold joint runs vertically or horizontally. Injection holes have to be angle drilled into the joint. For leaking cracks, drill the injection holes in a zig-zag pattern around the crack to make sure that the injection hole intersects the crack.
PREPARATION OF THE SUBSTRATE
Drill at 45° angle into the crack or joint. Ideally the injection hole should intersect the joint or crack half way through the thickness of the wall or slab. Blow the dust out of the injection hole with a probe that reaches the back of the hole. Fix a packer of the right diameter into the injection hole.
PREPARATION OF THE PRODUCT
Read the technical and safety data sheets prior to commencement of the injection works. Vigorously shake the Alchatek Gen Cat or Alchatek Gen Cat Fast accelerator before use and add the required quantity (2-10%) into the SPETEC PUR F400 resin. Mix the accelerator homogeneously into the resin and protect against moisture and rain to prevent premature reaction. Only mix the amount of material that can be used the same day.
PREPARATION OF THE EQUIPMENT
Depending on the application, injection can be carried out using a hand pump, pneumatic pump or electric pump. Use separate pumps for injection of water and polyurethane resin. Check that the pump is working properly. Prior to injection, the resin pump must be flushed with appropriate pump flush and be completely free of water to prevent pump blockage
APPLICATION
| • | Start the injection at the first packer; for vertical joints or cracks this is usually the lowest packer. |
| • | Do not over-pressurize while injecting; the correct injection pressure is the pressure that allows to resin to |
flow into the crack or joint. Avoid injecting at pressures of more than 1500psi (100bar).
| • | If unreacted resin comes out of the joint or crack, stop the injection and move on to the next packer. |
| • | After the last injection of resin into the packer, shoot a little bit of water into the packer in order to make |
sure that the last injected resin will react as well.
| • | Only catalyze the resin you will use within the next few hours. |
| • | Do NOT leave resin catalyzed with Alchatek Gen Cat or Alchatek Gen Cat Fast in pumps overnight or |
material will harden and permanently damage equipment.
• Always flush the pump out at the end of the day, or before extended breaks of hours or more. Resin left in the pump overnight can damage the pump.

REQUIRED TOOLS
Drill and drill bits of appropriate diameter and length. Alchatek mechanical Packers of appropriate diameter and length. Injection pump; manual, pneumatic or electric.
CLEANING AND MAINTENANCE
After the injection, clean the pump with Alchatek Pump Flush. If the pump will not be used for several days, flush the Alchatek Pump Flush out of the pump with lightweight motor oil or hydraulic fluid and leave it there until the next usage. Never flush the pump with water. After injection, remove the packers from the concrete and fill the holes with a fast setting cement or any other appropriate filler material.
COMPLIMENTARY PRODUCTS
For certain application where a faster reaction time is needed a special fast catalyst can be used. Alchatek Pump Flush, Mechanical Packers, Alchatek Oakum, and Injection Needles. SPETEC I.T.S KIT or SPETEC R-I.T.S SYSTEM must be ordered separately. See Technical Data Sheets.
ADVICE / FOCAL POINTS
Avoid injecting when temperatures are below -4°F (-20°C). In extreme cold conditions it is recommended to warm the resin and catalyst. Since SPETEC PUR F400 is water-activated, liquid water should be present.
