The new TeMa catalogues for environmental intervention works
TeMa Geo Solutions has presented two important publications summarising the products and technologies used in the field of major environmental works, which have enabled the Vittorio Veneto-based company to convince designers on all continents.
In addition to novelties, in the new catalogue we present solutions for intervention works in the environmental field that respect a new awareness towards protecting our natural heritage, which includes much hilly terrain and cultivated slopes. In recent years, these have been increasingly affected by climate changes that, in turn, have intensified some weather conditions.
We have included TeMa products for the major environmental works sector in the new Geosynthetic Products catalogue by TeMa Geo Solutions. In 48 pages, we present 29 products separated according to categories: drainage geocomposites, studded membranes, geonets, geogrids, geomats, biomats and geocomposites. They are all the result of research into new materials aimed at solving critical issues related to drainage, erosion control, filtration, separation, reinforcement, waterproofing and protection using dozens of applications (geotechnical and environmental) that the soil requires in certain hydrogeological and morphological situations.
Vineyards Catalogue
The same effective solutions with low environmental impact are offered in the Vineyards catalogue, specifically dedicated to safeguarding the vineyard heritage. It is, indeed, a centuries-old culture that has been a typical part of our lives for generations. We have only to consider the steps built by hand by farmers in the past. In the catalogue, we present various sustainable solutions, specifically for setting up vineyards and for their maintenance. The technological content of TeMa solutions goes hand-in-hand with its spirit of eco-compatibility, which has led to considerable savings, over the years, in terms of raw materials and CO₂ emissions into the air. TeMa has eliminated the use of millions of cubic metres of cement and inert materials with its “reinforced earth” technique, thus avoiding spreading thousands of tonnes of carbon dioxide and particulates that heavy vehicles would emit into the atmosphere in order to transport them.
The environmental choice of TeMa Geo
All this is accompanied by researching equally eco-compatible products that can be used in a natural context without spoiling it or changing its appearance. These are often 100% natural solutions which, despite being degradable over time, achieve their objective of settling the soil in a more than natural way.
Relying on TeMa Geo means making an environmental choice: you will discover that we have built four post-consumer plastic recycling plants to obtain, according to our own specifications, quality recycled raw materials to be used in specific percentages in our products.

Tips For Laying T-Kone
T-Kone is an HDPE studded membrane available in various versions: T-Kone S, T-Kone, T-Kone G Drain, T-Kone G Drain Plus and T-Kone G Drain Grip. T-Kone S and T-Kone are bare, whereas T-Kone G Drain is bonded with a geotextile, T-Kone G Drain Plus with a geotextile and a damp-proofing element, and T-Kone G Drain Grip with two geotextiles.
As you can see, you will need to make the right choice depending on what you want to obtain. Each solution meets different needs, including the mechanical protection of waterproofing and a drainage function. In any case, these applications are quick and easy to lay. Here, we can discover tips for laying T-Kone.
Mechanical protection of waterproofing with T-Kone
Where do I start?
First of all, you need to clean the work surface of any debris and check the wall to which the product is to be applied so that there are no defects that might damage the materials.
Then you need to use chalk to mark out the area where the drainage system is to be installed (a), making sure that you lay the membrane well beyond this point.
Start unrolling T-Kone (b) preferably from the centre of the wall, with the tab facing upwards, and aligned with the chalk line. The membrane needs to be laid with the studs facing the wall. This will create an 8 mm air gap between the waterproofing and the membrane.
Unroll the panels and apply them horizontally or vertically, fixing them against the wall. If the height of the wall does not allow it, they can be laid vertically and any excess fabric can be cut off. The sections must be placed side by side and overlap by about 20-30 cm on each side (a+b).
These are just a few basic tips for laying T-Kone. Discover all the applications for TeMa studded membranes directly on the site TeMa.

Environmental intervention works in keeping with our philosophy
An environmental reappraisal
Over the centuries the relationship between man and the environment has undergone considerable tensions. Rural development and the impetus in building have undoubtedly disrupted certain landscapes, reducing natural spaces to accommodate new urban and agricultural areas. This type of intervention work has led to a crisis in the ecosystem, imposing re-evaluation of the fragile balance between the economy and the environment.
This is the socio-cultural background that has led to global re-assessment aimed at defining programmes and new territorial management formulas. It has been the driving force behind TeMa Geo Solutions, the TeMa business unit dedicated to environmental intervention works. These are aimed at protecting land and offering the opportunity to operate using eco-compatible solutions and products that integrate into the environment without compromising its appearance or safety.
Sustainable development according to TeMa
Nestled at the foot of the hills declared a UNESCO World Heritage Site, the TeMa headquarters could not help but consistently correspond to this desire for sustainability, widespread in this area for some years now. But how has it contributed? By using raw materials responsibly, with 100% natural solutions and intervention procedures with low environmental impact.
Natural products
As a concrete example, TeMa addresses the problem of surface erosion of the soil by meteoric rain with Ecovernet® in natural fibres such as jute or Ecovermat® in natural fibres such as straw and coconut – or in biodegradable cellulose fibre. Installing products in this range allows intervention works to be carried out immediately, even in situations with difficult access for on-site vehicles. For such types of intervention works, total integration with the soil is achieved, guaranteeing lasting results over time.
Green intervention works
An interesting new development introduced by our technicians is the use of lightweight materials that feature reduced encumbrance, which not only affects the cost of the work but also speeds up the time required on-site. When building drainage systems, for example, TeMa does not rely on that range of inert materials from quarries that need to be extracted and transported. The company uses drainage geocomposites instead, such as Q-Drain, thus avoiding any waste of energy and CO₂ emissions into the air, thus ensuring quick installation.
These are just a few examples to show the potential that the field of environmental engineering has to offer:
- Reduction in costs while maintaining the effectiveness of intervention works
- Sustainability of the actions taken
- Protection and safeguarding of the soil
- Promotion of natural raw materials
To fully understand our philosophy, browse through the new catalogue dedicated to the protection of vineyards, which are the natural and cultural heritage of our lands and an identifying feature of our history. Inside it, you will find products and solutions for responsible and eco-compatible actions.

The importance of studded membranes
Research conducted in the building market has found that most construction disputes are due to damage caused by water and damp seeping into retaining structures.
Protecting foundations
In order to avoid inconveniences of this magnitude that are discovered in the course of time, designers and installers undertake to protect foundations. TeMa has therefore developed products and systems that protect waterproofing during backfilling operations, thus guaranteeing the stability of intervention work over time. For practical purposes, we propose two types of fairly common intervention works in civil engineering by showing you how two of our studded membranes work.
Retaining walls
Retaining walls are intervention works that have the main purpose of retaining slopes or soil embankments during works such as the construction of roads below ground level. Various types of wall can be built: in masonry or reinforced concrete, or using precast concrete elements.
Whichever solution is used, you always need to consider and comply with specific hydrogeological features: TeMa laboratories offer a range of membranes that meet such requirements, whereas technicians and installers can assist in choosing the best solution to use.
Mechanical protection of waterproofing
For the mechanical protection of waterproofing you can choose T-Kone, which also performs a damp-proofing and drainage function. Damp proofing creates a physical barrier between the structure and damp soil and avoids any possible damage to the waterproofing membrane, both during onsite operations and soil settlement.
The T-Kone family is part of a range of bare HDPE studded membranes (such as T-Kone S). Alternatively, these membranes can be bonded with a geotextile such as T-Kone G Drain or with a geotextile and a damp-proofing element such as T-Kone G Drain Plus.
Diaphragms and berlin walls
Suppose we need to work in an urban context doing underground intervention work. First of all, we must guarantee the stability of the structures surrounding the area to be excavated.
Diaphragms and berlin walls are used in situations where it is impossible to create excavation walls with an appropriate slope to prevent landslides or structural subsidence. In the form of steel/ reinforced concrete piles or walls, they are driven deep into the ground and coupled with TeMa membranes, which provide damp-proofing, mechanical protection or drainage functions.
Damp-proofing, mechanical protection or drainage functions
For this purpose, products such as Q-Drain can be used, which have a polypropylene monofilament drainage core bonded with one or two non-woven geotextiles, also made of polypropylene. These filter water and adapt to the conformation of the ground, thus guaranteeing stability.
These are just some of the membranes we are able to supply. Find out which one is best for you and assess the best solution with our team of experts. TeMa will assist you throughout each phase of the design process.

Geosynthetics: Advantages and Applications
Our passion for work does not stop, it simply continues at our company, in a little more limited way. You certainly cannot see us running up and down building sites or going in and out of our research labs, but we can assure you that we are still working on our production of geosynthetic products with the same commitment and perseverance in order to formulate new projects and develop ideas that we will see materialised soon, once everything has ended.
TeMa and Geosynthetic Products
TeMa Geo is the TeMa division created almost thirty years ago with the aim of exploring and expanding the world of geosynthetics, which it still does today. By “geosynthetic products” we generally mean all categories of synthetic coverings that are not only used in contact with earth or other building materials but are also appreciated for their use in various building fields. In the building industry, their main advantage is that they are user-friendly in technical terms, which is why engineers and planners prefer them to other technical solutions.
The Advantages of Geosynthetics
The advantages of geosynthetic options not only lies in the fact that they are easy to use but also in their cost-effectiveness: certainly less expensive, they provide excellent performance that remains unchanged over time. Furthermore, their versatile use makes them the ideal solution to various on-site problems.
Geosynthetic Products “In the Field”: the Serravalle Project
In more practical terms, today we want to tell you about the intervention works we carried out in the Piedmont region in 2016. It involved extension works for Serravalle Retail Park. In preparation for the works, we had to make the slope in front of the new complex safe. In order to proceed, we had to prepare several reinforced soil structures, separating them into banks, and solve the problems of surface drainage for the management of water, whose catchment area was located above the area.
For works of such magnitude, we used geogrids from the XGrid PET-PVC range as a structural element. In addition, to avoid any seepage in the future, drainage elements were installed close to the reinforced structures of the horizontal sections of each berm. This is just one of our products and one of the many fields of application explored by TeMa.

Dry Renovation: a Quick and Clean Method
At an historic moment in time when everything is coming to a halt, we must not forget that we still have ways to increase our knowledge and get ready for the time when everything gets back to normal. The home, for obvious reasons, is now the focus of our thoughts. The more days go by, the more we notice some jobs that have been left aside for too long: a basement to be fixed, a wall to be better insulated or a terrace floor to be changed because it is excessively damaged. So let’s discover something more about one of the ways to renovate those parts of the home that require our attention.
Dry renovation: a valid solution
The dry renovation system is a processing method that does not involve the use of water, adhesives or sealants that need to remain in place to dry. Although Italy has always opted for the so-called wet clay-cement system, this does not mean that new methods have not recently been explored. This traditional work method was cast aside during the years of crisis in Italy in the building industry, since it focused on protecting the existing heritage and, therefore, on renovating rather than building from scratch.
Renovating, synonymous with saving
After all, renovating becomes synonymous with energy efficiency. You save on your bills and gain in terms of wellbeing and living comfort, primarily by enhancing the value of your property. The dry installation system, which can be applied to the outside of a building, to its structure or to its internal system, offers many advantages.
We talk about the eco-sustainability of new materials, because they can be recycled, replaced if damage or deterioration occurs, and even re-used. Moreover, dry renovation allows much quicker intervention times and more sustainable situations because tenants do not need to leave their homes during intervention works.
The materials and method used by TeMa
In the specific context of TeMa Interior, the division dedicated to floors, balconies and terraces, soundproofing and waterproofing membranes are used that are easily shaped and transported because of their minimal weight.
Combined with dry installation, these materials allow short intervention times and greatly reduced costs. But remember that this does not entail any reduction in the performance of the intervention work. The final cost of any intervention will be lower because the thickness of the membranes is reduced and, consequently, the quantity of the materials used.
It is precisely the materials, with their physical properties and excellent performance, that ensure the efficiency of intervention work, first and foremost by facilitating the procedures involved.

Cycle/pedestrian paths: when we get back onto our saddle, we’ll know more about them…
We know that our bike has become a mirage. But we can promise ourselves to use it more when this period of seclusion is over. Meanwhile, why don’t we take advantage of the time available to discover interesting things all around us? For example, cycle paths. Let’s start at the beginning.
What is the correct definition of a cycle/pedestrian path?
It’s where you can ride your bike, of course. But, can pedestrians walk on it too? What is the direction of movement? Then there are increasingly more complex questions, such as: has it been built as a separate cycle path or as a reserved lane? Is it a cycle/pedestrian path or a vehicular/cycle path? In short, there are many features that a cycle/pedestrian path must have in order to be defined as such. Let’s take a look at them together.
The cycle/pedestrian path was invented to allow pedestrians and bikes to get about. Such paths require cyclists to respect pedestrians and get off their bike whenever necessary to avoid getting in the way. Consequently, they are not paths for the exclusive use of cyclists.
Creating these kinds of paths encourages people to get about without using a car, thanks to these dedicated spaces, where they can feel safe from urban traffic.
How do you build a cycle/pedestrian path?
In 2018 TeMa Geo Solutions built a cycle/pedestrian path in Cozzuolo di Vittorio Veneto (TV). One of the main aims of the project was to improve road safety in an area that is a gateway to the city and where a city park is situated, used by families and children.
First of all, we enlarged the road and the nearby roundabout in order to create the necessary space for inserting the path. The enlargement was facilitated by the construction of a reinforced earth escarpment, for which reinforced geogrids were used. Installed in the ground, they create friction and enable the system to withstand significant levels of stress. The intervention work, designed on the basis of a single berm positioned at about 2 metres above ground level, allowed pedestrian and cycle traffic in an area that had been dangerous from the outset.
Looking on the bright side, when you get back onto your saddle, you’ll be more aware of what’s under your wheels. Enter the TeMa world, visit our website.
TeMa: a support for the ground
Geo Solutions is the TeMa division that has been developing technologies and products for protection, maintenance and drainage in the field of major environmental works for over twenty years.
A SPECIAL FOCUS ON THE TERRITORY
More specifically, due to the location of its first production unit – situated near the hills that are now a UNESCO World Heritage Site – TeMa has always kept an eye on agricultural lands and especially wine-producing landscapes, which are now gaining increasing attention because of their economic importance and their environmental value.
This new focus on the landscape, including the agricultural one, has never been as relevant as now. We have officially entered the green year and therefore, today, we want to show you some systems for preserving your wine crops.
THE MAIN RISKS: EROSION AND DRAINAGE
The main risks that undermine the stability of the soil include: the natural erosion of the topsoil with the resulting need to reinforce it and the problem of water drainage.
EROSION: CAUSES AND SOLUTIONS
Soil erosion is caused by rainwater runoff, which, by removing the top layer of the soil, can cause significant erosion in the long term.
Various applications are available that provide protection against soil erosion. TeMa proposes natural and synthetic solutions, depending on the circumstances: a 100% natural jute fibre bionet can be used, or a three-dimensional PP geomat, such as KMat. A system of geosynthetic reinforcements (woven geotextiles or geogrids), once embedded in the subsoil, recreates a tensional layer that absorbs any stress of greater intensity than the soil.
DRAINAGE: CONSEQUENCES AND SOLUTIONS
Finally, to solve the fundamental cause of soil instability, namely drainage, TeMa has developed drainage trenches capable of removing water that is naturally absorbed by the ground. These are trench excavations, usually rectangular in section, filled with natural inert material, such as gravel or broken stones from quarries, with a high degree of permeability. Removal takes place either through the trench filling material or through the drainage pipe located at the base of the trench. To avoid another possible problem, i.e. clogging of the pipe, it is entirely covered with layers of non-woven fabric.
WHY CHOOSE TeMa?
Its attention to details, to small things, sets one company apart from all others. This is why TeMa stands out in its sector, thanks to its drive towards innovation and its respect for the environment, whose landscapes are unchanged after intervention works by TeMa.

Multiple interventions… Mainly in the private sector
In 2018, we were called to a private house in Pordenone. As a result of sudden and severe meteorological events, the escarpment behind a reinforced concrete retaining wall collapsed. We were quick to intervene to avoid any kind of damage, since the house was under construction and the environmental impact had to be almost minimal.
SOLUTION ADOPETD
We therefore decided to use our PET-PVC 55 XGrid, the uniaxial woven PET geogrid that provides new stability for soil. It is a reinforcement geogrid made of polyester synthetic yarns, obtained by weaving, which is highly resistant and coated with a protective layer (PVC). Uniaxial PET-PVC XGrids are used to implement soil reinforcement support works, whereas biaxial XGrids are used for soil reinforcement and stabilisation.
