GUNITADO DE PISCINAS

Por diferentes aspectos que ahora analizaremos, la técnica del gunitado ha revolucionado el mundo de la construcción de piscinas. Pero, antes de continuar ¿qué es exactamente el gunitado?

El gunitado es una técnica constructiva consistente en proyectar a gran velocidad sobre una superficie, el hormigón o mortero con una manguera o cañón y aire comprimido. El material proyectado es un hormigón cuyo tamaño máximo de áridos no es superior a 8 mm y que, aplicado a máquina, se proyecta a gran velocidad sobre un soporte a través de manguera y boquilla.

Esta técnica permite construir prácticamente sobre cualquier superficie, inclusive la tierra. Hoy en día, el gunitado se utiliza también para el acondicionamiento de taludes revestimiento de túneles, obras subterráneas, barrancos y carreteras donde Bulcan Arte posee una constatada experiencia. En estas actuaciones, el método ofrece una alta durabilidad reduciendo los costes de mantenimiento posteriores.

En la actualidad se usan tres procesos distintos, que son: Mezcla seca, mezcla húmeda y mezcla semi-húmeda. El proceso de mezcla húmeda conlleva el empleo de más servicios, pero su uso está generalizado para grandes aplicaciones.

En el caso de la construcción de piscinas, las características que posee y que lo han convertido en la mejor técnica son:

  • Mayor resistencia por metro cuadrado, es decir, con menos material se consigue mayor resistencia. Esto revierte también en la firmeza de la estructura gunitada al obtener una capa más compacta y sólida.
  • Reducción de los costes al necesitar menor grosor que, por ejemplo, el hormigón armado, y evita la preparación de los encofrados que siempre son una pérdida de tiempo y que siempre acaban repercutiendo en el presupuesto, en especial en aquellas grandes obras con formas muy originales.
  • Impermeabilización total. Ofrece una estanqueidad óptima del vaso de la piscina al existir menos poros en las paredes del mismo.
  • Flexibilidad. Por la versatilidad de la técnica, se pueden construir piscinas de diseños originales aun teniendo formas complicadas para las técnicas tradicionales, con unos resultados óptimos. La ventaja radica en que se moldea directamente sobre el terreno.
  • No necesita compactación (tampoco el autocompactante) por lo que, como señalamos anteriormente, se puede adaptar a superficies de todo tipo y geometría.

Como verás el gunitado se ha convertido en el material más óptimo para la construcción de esa piscina que todos queremos tener. En Bulcan Arte tenemos una amplia experiencia adquirida durante años en la aplicación de esta técnica sobre diferentes superficies y en diferentes circunstancias por lo que, si necesitas asesoramiento, estaremos encantados que te pongas en contacto con nosotros a través de nuestros teléfonos o nuestro formulario de contacto.

TYPES OF GARDENS AND THEIR CHARACTERISTICS

The word “jardin” (garden) comes to Spain in the fifteenth century but its origins come from the term “jardin”, known since the twelfth century, seems to come from the Latin-Germanic compound hortus gardinus which literally means “garden surrounded by a fence”, Hortus from Latin, fructi garden, or gart or gardo “closed”, as if the garden had to defend against the animals and even the thieves. The garden can be defined as the land where plants and flowers are grown with decorative and ornamental motifs.

The construction of the first known gardens dates back to the time of the Egyptians, who built authentic gardens along the banks of the Nile River. The need to create spaces for leisure and meeting, the human need to live with nature and Capacity (sometimes with negative connotations) to modify our environment to adapt to our needs has generated around the world different styles of gardens and landscapes related to cultures and adaptations to different climates and species of the planet.

We can define landscaping as the study or design of the natural environment, especially parks and gardens. The landscaper plans and designs urban and rural landscapes in time and space, based on the natural characteristics and historical and cultural values of the place. To achieve this, appropriate techniques and natural and / or artificial materials are used, guided by aesthetic, functional, scientific and planning principles. In Spain, we can find the Spanish Association of Landscapists founded in 1952 as an Institute of Studies of Gardening and Landscape Art

The styles of gardens are as many as cultures and places are in the world, but in a very general way we can talk about:

MEDITERRANEAN GARDEN

It is a style marked by the dry climate that generates environments of great beauty based on materials of the region such as stones and drought-resistant vegetation. Light coloured stone walls, water in movement and brightly coloured flowers. All this with a minimalist touch that represents the most typical of the Spanish, French and the Italian gardens of the region of Tuscany.

CLASSIC OR CONTINENTAL ROMANTIC GARDEN

This type of gardens has great extensions where the control of the handwork of the man is tangible in the linear of hedges trimmed and the grass perfectly mowed. They are geometric gardens with straight lines, with pastel colours and a multitude of shades of green. The paths are of sand or gravel and in them are placed classic sculptures or pots of clay. They are gardens with special splendour in the Fall season. Good example of them are the typical French or English gardens.

TROPICAL GARDEN

They are gardens of the most exotic areas of the planet where the climatic conditions of constant temperature and humidity allow their development. The protagonists are tropical and exotic species as well as abundant vegetation. The type of characteristic plants has particularly large leaves and only few flowers that require low attentions.

These gardens do not require excessive care since they pretend to simulate the frondiness and disorder as the jungle. Only the species should be pruned when they disturb, if it is not the case, they should be allowed to grow naturally. Outside of its environment is recommended the construction of ponds or waterfalls with typical rocks of the area, taking advantage of or creating unevenness that contribute the level of environmental humidity needed for this type of plant diversity.

FENG SHUI GARDEN

Of Chinese origin, it is meant to be a study of the energies transmitted between nature and man. These are small spaces, relaxing, balanced and with circular or wave forms. Feng Shui art, whose meaning is “wind and water,” runs away from over-detail and ostentation, using elements of composition such as rocks, plants, sculptures, walls, pots, elements with water and ornaments.

JAPANESES GARDENS

They are one of the most famous architectural elements of mankind. The design and the elements that compose it can be analysed from a geographical or topographical point of view. Thus, the landscape of the garden represents an archipelago of islands located mostly around the Seto Inland Sea. The Japanese garden also represents the cosmos, place of central importance in the Shinto religion. A large void (equivalent to the sea) full of celestial bodies (islands).

The Rocks are the stars of these gardens. They represent mountains or islands, scattered in a vacuum that mimics the sea. The most used are those of volcanic origin, mainly those of basalt.

ARABIC GARDEN

It is a garden to walk, see and hear, and express the longing for paradise. It is a garden that fascinates due to its sensitivity, its intimate character and the harmony of its parts. The main characteristic elements are:

  • Divisions of private spaces: when the dimensions of space allows it, the space should be divided into rooms communicated through narrow passages with arches, bars, lattices or other elements that allow us to glimpse the next room providing mystery and sensation of discovery.
  • Water is always present: the water goes through the different places in the garden, even entering the rooms and bringing freshness, sound and movement.
  • o   Structural elements: paved walks, walls, piles, arches, fountains …, generally of stone or covered with tiles of varied designs and marked Arab character.
  • Mediterranean plants arranged in the paths and pots and that withstand well the drought. The cypress and orange trees are the most characteristic trees.
