In this post we will discuss the many advantages of GT350, as we follow through with the overview of the Alchemy-Spetec product line.

What is GT350?

GT350 is an MDI based hydrophilic, one-component flexible polyurethane injection resin for waterproofing.

What are the advantages & applications?

GT350 is used for shutting off water leaks in concrete, brick work and sewers where movement and settlement may occur. It can also be used for water cut off in walls. In addition, GT350 can be injected behind sheet piles and secant piles for curtain wall grout repairs. Last but not least, it can be used in tunnel joint segments and open wall joints with highly active water leaks.

Additional Information

Cured polyurethane is harmless for the environment and highly flexible, making it resistant to biological decay. It is ideally suited for structures where a high degree of settlement and movement can occur.

In the previous post we went over the properties of AG100. Today we will discuss the properties of AG200, which is in the same family. (If you haven’t already, be sure to check out my previous blog post on AG100.)

What is AG200?

AG200 is a three-component, water-swelling hydrogel based on acrylate or methacrylate that hardens to an elastic product.

What are the advantages & applications?

AG200 is known for its low blending viscosity, which can be compared to the consistency of water. This acrylate is mainly used for curtain wall grouting. In addition, it can also be used to redirect ground water, stabilize soils prior to excavation, and inject cracks. The set times can be controlled by varying the amounts of catalyst on the resin side and salt on the water side.

In this post, I’ll continue my overview of the Alchemy-Spetec product line with a profile of H100. If you haven’t already, be sure to check out my previous articles on F400 and F1000.

What is H100?

H100 is a one-component, closed cell, water activated, semi-flexible polyurethane leak seal injection resin.  Its low viscosity and hydrophobic properties make it ideal for both soil stabilization and cutting off large water leaks.

What are the uses for H100?

There are a plethora of applications for H100, primarily cutting off high flow leaks and soil stabilization. Some specific uses include cutting off sewer water leaks and soil stabilization around sewer structures. Other uses include water cut-off of leaks in foundations such as diaphragm walls, piling sheets and secant piles. H100 is also good for stabilization and water cut-off of large cracks, voids and gravel layers. H100 has been used to stabilize soil and anchors in porous geology along with crack and gravel layer injections in concrete structures. In addition, it's is an ideal resin for probe grouting below grade pipes and manhole injections. Last but not least, injections in combination with cement-based grout work very well with pre and post injections in mines, tunnels, pipe jacking, drill & blast and TBM applications.

Advantages of H100

The one component, closed-cell structure allows the cured polyurethane resin to seal large water leaks in cracks and joints permanently. With adjustment of the percentage of H100 ACC accelerator it is also possible to alter the reaction times. Once H100 is cured, it exhibits high strength and good chemical resistance. This in turn makes it harmless to the environment and resistant to biological attacks. Not to mention it is also WQA certified to come in contact with drinking water.
