The area covering about 2,000 sqm required some intervention work regarding reinforced earth structures and drainage. In particular, we undertook the preliminary work for extension works dating back to 2016.

To the south-west of the building, the soil was secured and then surfaces were replanted with greenery.

Let’s see how this was done in more detail.

Type of intervention

In order to make the slope in front of the complex secure, the intervention work involved constructing reinforced earth structures in several banks, more specifically 3 modules of 6 m in height each.

In addition, to manage the water coming from the hydro-geographic basin situated upstream of the area, specific surface drainage works were carried out.

The solution from TeMa Geo Solutions

For the reinforced earth structure, 3 modules were constructed with anchorage lengths of 7 m and a strength of 110 kN/m provided by X-Grid PET PC 110 geogrids.

As for drainage, instead, a Membrana Nera Geo was used, the 8 mm HDPE studded membrane bonded to a filter nonwoven geotextile with a PE slotted tube at the base.

The drainage system was also installed at the horizontal contact points of each berm to prevent future water seepage into the reinforced earth structure.

This is why the WHO and a number of laws govern the use of noise remediation systems in cities: the Framework Law no. 447 of 1995 for Italy and the European Directive on Environmental Noise no. 49/2022. If the cause of the noise cannot be addressed, the solution is to install protective barriers. Various kinds can be used, but in this case we focus on reinforced earth structures that require specific measures, which we discuss here.

For example, the Pedemontana Veneta is a new toll motorway in Italy: nearly 100 km long. Almost entirely in operation in the north-east of the Veneto region, the main route of this motorway runs through a deep trench in order to minimise the ‘territorial’ and environmental impact on the surrounding area. This means that long sloping areas of reinforced earth can be found along the sides of the motorway, with rows of trees and hedges for 58.61 km and green areas covering 1,333,410 square metres of hedgerows, groves, grassy slopes and tree-lined meadows.
A focus on noise with much regard for the landscape.

What do reinforced earth noise barriers consist of?

For this type of embankment with its typical trapezoidal shape, earth is used that will be covered by vegetation over time. Geosynthetic reinforcements and geogrids are added to support the earth, which already has good compressive strength. These are inserted horizontally into the ground and develop friction and tension that stabilise the structure, increasing its resistance to stress.

The TeMa Geo Solutions offer includes the X-Grid Pet PVC range of geogrids, with different resistance values, which are ideal for all kinds of contexts.

Another aspect to bear in mind is surface erosion of the soil: to counteract this, synthetic geomats are applied, also with a mulching function to encourage the growth of grass cover, or natural fibre bionets.

Also in this case, TeMa Geo Solutions offers a wide choice ranging from Ecovermat F Grass and Ecovernet FJ to the K-Mat range.

Why use a vegetation barrier as a protective noise barrier?

A vegetation barrier has an unquestionable ability to limit the spread of sound waves: some of them are absorbed, some reflected and some deflected. As a result, the amount of sound waves reaching the receiver is greatly reduced and noise can be dampened by several decibels.

The advantages of a reinforced earth sound-deadening barriera

Creating reinforced earth structures brings considerable advantages:

• it costs less because you can often use earth available on-site
• no special maintenance is required other than regular trimming.
• it helps the environment and integrates with it: the use of vegetation also reduces vehicle emissions by absorbing CO ₂ and purifying the air.

We’re in the eastern corner of the Veneto region, the Prosecco hills have outdone themselves once again this year and a steady stream of grape-laden trailers continue to roll past on their way to the wineries. But this year’s harvest has had to contend with rather uncertain weather patterns: frosts in late spring, persistent rain interspersed with dry spells, with violent storms and hail over summer.

These conditions certainly don’t help the soil, putting it at risk of slips, subsidence and erosion. But if we apply TeMa Geo Solutions’ modern technologies and materials designed for this very purpose, we can protect the land from damage and, what’s more, do it in a sustainable way.

Not far from here, just a few kilometres from our headquarters, the Prosecco hills fall largely within the UNESCO World Heritage Site, meaning any measures must be strictly reconstructive, designed to protect the status quo and absolutely non-invasive: “gentle” on the environment.

TeMa Geo Solutions has come up with high-performance solutions to control the natural erosion of the soil, reinforce slopes, and drain water with:

• biodegradable fibre matting made from 100% natural jute such as Ecovernet® J500 XL and Ecovermat P Grass, which provide protection to stop soil being blown or washed away by the elements, and encourage vegetation;
• the K-Mat F erosion control synthetic geomat;
• reinforcement geogrids such as X-Grid PET PVC, which can withstand considerable stress levels;
• the Speedrain drainage geocomposite, which drains away water from the surrounding soil, stabilizing any surface slips.
