They meet the need to recover usable spaces as they can also be built with a steeply sloping face.

The authentic green appearance

Nowadays, the modern building industry is highly aware of sustainability and territorial integration. Under certain conditions, reinforced earth retaining walls can replace conventional concrete walls, without underestimating the aesthetic appearance of the landscape. This is even more important in areas subject to landscape restrictions that require the preservation of natural aspects using specific materials and construction techniques.

TeMa Building solutions integrate these trends by catering to various problems concerning land conformation and hydrogeological protection.

The functions of reinforced earth retaining walls and the products required to achieve them

Slope gradient, exposure to weather conditions (including severe ones) and the mechanical properties of the terrain often require technical solutions that stabilise a slope. Synthetic products can be used, each one performing a specific function.

Reinforcement with geogrids

The compressive strength of the soil is combined with the tensile strength of the geosynthetic product (such as T-Grid). The friction involved develops a tensional state that stabilises the structure.

Profiling with formwork units

Electro-welded metal structures such as formwork units provide a shaping of the soil face up to a 65° slope.

Controlling surface erosion with erosion control mats

Severe or prolonged weather conditions, such as strong winds and sudden downpours – and the resulting surface run-off of water – could lead to erosion and depletion at the face of reinforced earth layers, particularly if they are fully greened. The solution to this problem is to use, on the face of each layer, three-dimensional synthetic mats such as T-Mat made of polypropylene or K-Mat FG Green made of fibreglass. Alternatively, natural, biodegradable mats made of jute fibre such as T-Juta 500 can be used (also available in an XLversion).

Soil containment using gabions

An alternative solution to reinforced earth walls can be found in walls built using double-twisted wire mesh gabions, such as T-Gabion, filled with pebbles. Gabions are also an interesting solution for smaller residential projects: they provide containment while offering a different and innovative aesthetic appearance.

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.
