SPETEC SOIL-H40 T.D.S
DESCRIPTION
SPETEC® SOIL H40 is a solvent and phthalate free, water reactive, hydrophobic, one-component low viscosity polyurethane injection resin designed for soil stabilisation.
ADVANTAGES
- One component
- Very low viscosity.
- Different reaction times are possible by adjusting the percentage of
SPETEC® Geo Acc accelerator.
- Injections in compact soil layers up to coefficient 106 m/s are possible.
- Cured polyurethane chemically anchored with substrate exhibits high strength and good chemical resistance. (contact our Technical Service department for more information)
- Cured polyurethane is harmless for the environment and resistant to biological attacks.
FIELD OF APPLICATION
- Soil and gravel layer stabilisation.
- Pre- and post-injections in mines, tunnels, pipe jacking, drill & blast
and TBM applications.
- Injections in combination with cement and micro fine cement.
- Anchoring and micropiles.
- Stabilisation of quay walls, floor slabs, roads, slopes and sewers.
- Curtain grouting
- Damming of chemically contaminated soil.
APPLICATION
Note : the following is a typical application description. In case of other jobsite parameters, please contact our technical department.
PRELIMINARY ANALYSES
Check if the soil is porous enough to allow the resin to flow. Clay soils can not be injected. Check the depth of the eventual water table.
REQUIRED TOOLS
Appropriate injection pipes of the correct length. Appropriate machinery to install the injection pipes into the soil substrate. Injection pump; manual, pneumatic or electric.
PREPARATION OF THE SUBSTRATE
Install the appropriate injection devices at the right position. Injection can be done via strainer pipes or Manchette pipes (TAM pipes) / Sleeve pipes. The exact position, spacing and matrix layout of the injection pipes has to be determined by the consulting engineer.
PREPARATION OF THE PRODUCT
Read the technical and safety data sheets prior to commencement of the injection works. Vigorously shake the SPETEC® Geo Acc before use and pour the required quantity (0,5-2%) into the SPETEC® SOIL H40 resin. Mix the accelerator homogeneously into the resin and protect against moisture and rain to prevent premature reaction.
PREPARATION OF THE EQUIPMENT
Depending on the application, injection can be carried out using a hand pump, pneumatic pump or electric pump. Preferably use a separate pump for injection of water and polyurethane resin. Prior to injection, the pump must be flushed with SPETEC® PUMP CLEANER and be completely free of water to prevent pump blockage.
INJECTION
In case of Strainer pipes.
Start the injection at the first injection pipe. Start the pump. Inject at the pressure where the resin begins to flow. Do not over pressurise during injection. Measure the amount of resin being pumped into the strainer pipe and stop when the required quantity has been injected. After this move to the next strainer pipe. Continue until the whole matrix has been injected.
In case of Manchette pipes.
Put the inflatable packer at the lowest point of the TAM pipe and start the pump. Inject at the pressure where the sleeve opens and the resins starts to flow into the soil. Measure the amount of resin being pumped. Stop after the predetermined quantity of resin has been injected. Move the inflatable packer up to the next sleeve and repeat the injection procedure. Continue till you reach the last upper sleeve of the TAM pipe. Repeat the procedure for every TAM pipe in the matrix.
APPLICATION CONDITIONS
Avoid injecting by temperatures below -20°C. In extreme cold conditions it is recommended to warm the resin and catalyst.
CLEANING AND MAINTENANCE
After the injection, clean the pump with SPETEC® PUMP CLEANER. If the pump will not be used for several days, put oil into the pump and leave it there until the next usage. Never rinse the pump with water.

ADVICE / FOCAL POINTS
Water must always be present during the injection of SPETEC® SOIL H40 as it is a water-reactive resin. Avoid injecting at shallow depths; this can result in distorting the cohesion of the upper soil layer.
