The function of retaining wall structures is to retain and reinforce soil faces. They can be built in a multitude of areas, including private ones such as gardens and vineyards, as well as public areas such as roads, railways and embankments.
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.
