Montan is a unique, pre-expanded resin. It is produced on site from a liquid base which can produce many times its own volume, making one delivery to site sufficient for most applications. Montan flows only under applied pressure, and is inert, solvent-free, non-toxic and non-flammable. The product can be poured, pumped or injected into holes, voids and interstitial spaces, and pumped laterally over long distances. Montan has a short gel time and can even be applied underwater.
Pipelines – Montan is ideal for filling pipelines and conduits. Residual liquids are forced ahead and expelled. An abandoned pipeline can be filled completely, even if only one end is accessible. Uphill or downhill—Montan won’t run out. When used to fill the interstitial (annular) space formed by relining, the new slip line will not collapse or float when being installed.
General Void Filling – Montan offers a complete and lightweight fill for shafts, tunnels and caves. Only simple forms of containment or shuttering are necessary, as Montan will only flow under pressure. Montan can also be removed to re-open access, if required.
Embankments – Seeping water affects stability, creating water paths which increase over time. Such paths and voids can be plugged by injecting concentrated Montan. Leaks due to clay shrinkage and animal activity can also be sealed.
Retaining walls & culverts – Cavities behind retaining walls and under culverts can be filled, even if remote from the road. Montan can be pumped a long way using portable equipment.
Backfilling – Montan is ideal where site access is difficult. By filling and supporting without exerting hydrostatic pressure, it makes excellent backfill, sets quickly and is safe for plants, grass and animals.
