TeMa Geo Solutions: geotechnical solutions

The TeMa Geo Solutions division has developed considerable experience in geotechnical applications and developed technologies and products, thereby ensuring that designers can meet increasingly strict regulations concerning the environment and the landscape.

These applications are for the protection, maintenance, retention, reinforcement and drainage in the field of major environmental projects, involving products that provide innovative efficient and long-lasting solutions.

We are aware that a kind of public resistance to sustainability announcements has already begun. We are therefore interested in helping companies that are taking appropriate action to protect the environment. This is not only to ensure that they can better comply with regulations but also, and above all, to increase the effectiveness and credibility of their work.

 

TeMa Geo solutions in applications

The areas of expertise of TeMa Geo Solutions include:

  • football fields
  • landfills and contaminated sites
  • tunnels
  • reinforced soil retaining structures
  • dry slopes
  • grassy road and railway embankments
  • roads
  • drainage ditches
  • horse training and racing tracks.

 

Products and functions: a range starting with geosynthetics

Geogrids are structural elements used to reinforce soils in the construction of retaining walls, block retaining walls, reinforced soil retaining structures, landfills and contaminated sites. The open mesh structure allows the reinforcement geogrids to develop ‘passive’ resistance at the transverse ribs, thus effectively increasing their inherent stabilising effect and enabling the system to withstand significant levels of stress.

The TeMa Geo Solutions range includes uniaxial or biaxial X-Grid geogrids made of fibreglass, polyester or PET coated with a polymer layer, coupled, or not, with a nonwoven geotextile, to be chosen to suit the project.

Offering products such as bentonite geocomposites, drainage geocomposites, facings, erosion control mats and essential accessories, the TeMa Geo Solutions range fulfils various functions for the retention anddrainage of rainwater and groundwater.

The TeMa Geo world offers its long-standing (since 1993) expertise and experience in the polymer-based product category (geosynthetics). Over the years, research at its in-house labs has enabled the development of solutions that integrate with the environment in a more specific sense, such as biodegradable erosion control mats, and in a broader sense, such as geomats and studded membranes.

 

TeMa also offers cutting-edge geotechnical solutions for vineyards

This is not surprising, as the TeMa Geo headquarters are situated on the eastern edge of the Prosecco hills, a UNESCO World Heritage Site. The company therefore has made its experience available to preserve and protect the viticultural landscape with its products for erosion control, reinforcement and ground drainage in an environment subject to the passage of agricultural vehicles.

Damp, rising damp and efflorescence in basements.

rising damp water mold damp efflorescence

Damp, mould, stains and flaky plaster in basements are a homeowner’s worst nightmare. We’ve mentioned numerous times that weather events and groundwater, where not controlled properly, are the main cause of damp. Of course, it doesn’t just affect the walls, but the whole structure, including flooring, on the basement level or even on the ground floor.

The phenomenon that’s so often underestimated is so-called “rising damp”, which occurs when water under the ground enters walls as a result of direct contact and is pushed upwards by capillary action, allowing the moisture to rise around ten centimetres or more. The moisture can even climb metres up the wall by “latching on” to molecules of a different kind, in this case those of the actual walls. The damage caused by the abnormal increase in moisture inside walls is immediately visible on the walls of ground-floor rooms or basements.

 

What effects the water’s capillary action has

The effect of capillary absorption manifests in the form of:

  • static damage to the building, which is weakened and becomes less safe
  • worsening occupant comfort as a result of unhealthy, smelly rooms
  • cosmetic damage, with the appearance of stains and peeling plaster
  • higher heating costs due to the lower surface temperatures of internal walls
  • efflorescence
  • a capillary action that causes water to rise through walls, bringing with it salts from the ground that, once they crystallize as a result of the evaporation process, swell and cause paint and plaster to peel: white stains forming around cracks are known as salt efflorescence.

The effects are less visible when the surface affected is flooring, with symptoms like swelling, salt efflorescence, mould or changes in the colour of grout often only appearing later on.

All these issues derive from the misguided choice of materials, or poorly designed and executed work, often compounded by the fact that the foundations’ waterproofing is damaged or even non-existent. This is not an issue linked to weather events, rather it stems from the presence of groundwater.

 

How TeMa Building Solutions can help

Both rising damp and efflorescence issues can be prevented with the use of suitable materials. TeMa Building Solutions offers an extensive range of studded membranes and drainage geocomposites to remove water before it comes into contact with the structure and to provide waterproofing with reliable, lasting protection.
