SANIPOR® Environmental Aspects

SANIPOR® works with two environmental friendly liquid silicate grouts, made and supplied 

  • in the UK by Brenntag UK

These inorganic grout - injections form a durable silicate, soil-like conglomerate underground, chemically similar to sandstone, clay or glass. (inert/neutral materials)

None of the SANIPOR® components are toxic, mutagenic or carcinogenic as organic resins can be. They are hazard-free to humans, air, the surrounding soil and ground water. The complete reaction of the two components is practically independent from their mixing ratios or dilution with (salt- or ground-) water.

Under special - industrial - conditions

Industrial areas have often contaminated soils and tend to pollute ground water due to leaking water collection systems.

To prevent further pollution and partially remediate the soil in the surroundings of leakages SANIPOR® can be of great help.

It can -in situ- encapsulate contaminations. Toxic materials around leaks will be vitrified, and cannot be dissolved and washed away by ground water any longer.


The inorganic, sandstone like chemical character of the SANIPOR® grout is inert against oil, oil derivatives and organic solvents.

Not all types of grouts are equal

Grouting materials for injecting soil (to make it stable and/or watertight) have been in use since the 19th century. Especially the inorganic ones have a long technical track record in the engineering literature. The inventors of Sanipor modified the composition of the silicate based grout in order to combine several advantages and utilize them as a reliable "low-tech" (based on hydrostatic pressure, path of least resistance) method to seal sewer collection systems comprehensively, eco-friendly  and long lasting. The created grout envelope around the leaks is equivalent to a layer of  homogenous clay soil. Impermeability factor  K(m.s-1): 5.6 x 10-9
