Trisoplast Mineral Liners International Bv

Trisoplast Mineral Liners International Bv

Trisoplast is a robust, flexible, durable and sustainable isolation solution consisting of a special clay-polymer component mixed with sand and water. Perfect as an environmentally protective bottom liner for landfills, tank terminals, industrial sites and infrastructure. Trisoplast is also the solution for making underground structures watertight, and for the construction of ponds and water basins, for example. This patented Dutch top product is used all over the world. And has been for more than 20 years now.

Trisoplast is now used all over the world. From China to America. This success story started right here in the Netherlands. In 1995, to be precise. That was when GID (the operating company responsible for the use of Trisoplast in the Benelux region) installed the first Trisoplast bottom liner at a landfill site.

This initial order, from a waste management company in Amersfoort with a nine hectare site, was a great suc-cess. This project got the Trisoplast brand off to a great start, and helped make it the success that it is today. After that first project, it did not take long before other landfill sites discovered the benefits of this ultra-strong liner. In the years that followed, this product became the most popular mineral liner at Dutch landfill sites.

Partners throughout the world
Trisoplast established partnerships throughout the world, becoming a global, frequently used solution in the process. Both within the world of waste management and beyond. In addition, this unique combination of ben-tonite clay-polymer gel, filler and water is being widely used in civil engineering projects, landscaping and in-dustry.

Trisoplast is a robust, flexible, durable and sustainable isolation solution that is used in all kinds of projects around the world. From a mineral bottom liner in landfills to water isolation systems in civil engineering projects and water features on golf courses. Initially developed by the Dutch company Tritech Natural, Trisoplast has been in use for more than 20 years. But how does Trisoplast work exactly?

Trisoplast consists of a special clay-polymer component mixed with a mineral filler. Sand is extremely suitable for this purpose. Trisoplast’s highly effective isolation properties are due to the third ingredient – water. A robust layer of this mixture is installed on-site. It can be immediately covered with a ballast layer of sand or soil, for example. This provides the necessary overburden. Next, any water from the surrounding soil that comes into contact with the Trisoplast layer will be absorbed. This creates a matrix of chemical bonds between the swelling clay minerals and the dissolved polymer. The resulting strong, dense hydrogel structure has considerably better isolation properties than traditional liners. This swelling hydrogel fills up the pores in the granular filler (e.g. sand). It is this gel’s impermeability and flexibility that make Trisoplast unique. At the same time, the gritty structure of the filler lends mechanical strength to this mineral layer. The weight of the overlying ballast layer helps to keep the Trisoplast layer at peak strength, by preventing any excessive swelling.

Proven protection
Trisoplast has been around for well over 25 years. During that period its environmental protection and isolating properties have been regularly tested by various internationally recognised knowledge institutes. Comparative studies have shown that Trisoplast has significantly better isolation properties than traditional clay liners and the geosynthetic clay liners (GCLs) that are now in common use. This is partly why it offers a higher level of environmental protection and a substantially longer service life. It is important to point out that our solution consists of almost exclusively of natural constituents. Thanks to this combination of properties, Trisoplast’s market share in the isolation of Dutch waste disposal sites currently exceeds 90 percent.

Easily moulded
In addition to its versatile range of applications, Trisoplast is easily moulded around ducts and structures. Trisoplast’s self-healing capacity and its robust composition make it highly resistant to puncturing by sharp elements (pebbles, construction waste, etc.) in the top and bottom layers, which are unavoidable on a construction site. Film-based solutions (geomembranes), for example, are far less resistant to puncturing. Its chewing gum-like properties mean that Trisoplast is easily moulded, which is invaluable on poor substrates and when built structures settle. Trisoplast has a substantial water retention capacity and is resistant to shrinkage. So, in situations where traditional clay liners tend to dry out and crack, Trisoplast goes on working. Together, these properties result in a durable, safe and simple liner that is quick to install. Even when it has to be fitted around numerous connections.

The innovative mixture of natural constituents, combined with polymer technology, gives Trisoplast a longer service life than many other liner materials. This is an essential property in the sectors where Trisoplast is used. Whether these involve projects in construction, waste management or landscape architecture.
Opt for durability
The problem with many lining products is that their performance eventually becomes degraded by environ-mental factors. This can sometimes happen very gradually, sometimes very quickly. If performance falls below the minimum requirements imposed during a project’s design phase, then measures need to be taken. You naturally want to avoid these follow-up costs, or to put them off for as long as possible. If the system needs to be replaced, this often means that the entire structure has to be reworked. Aside from the enormous expense involved, this results in considerable inconvenience to the user and to those living in the immediate area. In addition, still more scarce raw materials are consumed in the process of replacing these systems. The solution? Opting for a sustainable material with a long service life.

And that’s where Trisoplast comes in. We used a unique mixture of constituents to create an innovative solution that is much more resistant to environmental factors over time. Thanks to its high plasticity and chewing gum-like properties, this system is highly resistant to cracking and tearing – problems that often affect other liner systems. Trisoplast is also unique in terms of its mechanical properties. High friction angles, combined with enormous cohesion, make it possible to design steeper slopes without the need for extra reinforcement. Its superior isolating properties (which are due to its unique composition and polymer additive) also set Trisoplast apart from the rest. This means a thinner layer of liner is sufficient, which creates more usable space. In other words, once the system is in place, you will have peace of mind for the foreseeable future. In this way, we can make life easier for our clients, keep the longer term costs to a minimum, and protect the surrounding area using a proven natural solution.
