Abstract

Procedimiento para la deshumidificación de muros. Comprende la inyección, en el cuerpo de los muros a tratar, de unas resinas capaces de absorber y retener la humedad presente en aquéllos, con extracción y examen de muestras de los materiales, y la preparación e inyección de resinas a base de siloxanos oligoméricos, distinguiendo las operaciones según sea el espesor de los muros a tratar. Posteriormente, se eliminan los revocos existentes y se realizan otros nuevos.Procedure for dehumidification of walls. It includes the injection, in the body of the walls to be treated, of resins capable of absorbing and retaining the moisture present in them, with extraction and examination of samples of the materials, and the preparation and injection of resins based on oligomeric siloxanes, distinguishing operations according to the thickness of the walls to be treated. Subsequently, the existing plasters are removed and new ones are made.

Description

Procedimiento para la deshumidificación de muros.Procedure for dehumidification of walls.

Field of the Invention

La presente invención se refiere a un procedimiento para la deshumidificación de muros.The present invention relates to a procedure for dehumidification of walls.

Como expresa el enunciado, se trata de la eliminación de la humedad presente en muros y paredes estructurales de construcciones y obras.As stated in the statement, it is about the elimination of moisture present in walls and structural walls of constructions and works.

Background of the invention

La presencia de la humedad en estructuras de edificios y otras construcciones constituye un problema clásico en el mantenimiento de dichas partes portantes y, desde hace mucho tiempo, se viene combatiendo sin haberse logrado resultados satisfactorios.The presence of moisture in structures of buildings and other constructions constitutes a classic problem in the maintenance of said bearing parts and, for a long time time, is fighting without having achieved results satisfactory

La naturaleza, especialmente la permeabilidad, de ciertos materiales empleados en las construcciones ha hecho tradicionalmente difícil la expulsión de la humedad y, por consiguiente, de una de las causas de la disminución de la resistencia y la consistencia de dichas estructuras.Nature, especially permeability, of certain materials used in construction has made traditionally difficult to expel moisture and, for consequently, of one of the causes of the decrease in resistance and consistency of these structures.

Brief Description of the Invention

El nuevo procedimiento consiste en la inyección en el cuerpo de los muros a tratar, de unas resinas capaces de absorber y retener la humedad presente en aquéllos.The new procedure involves the injection in the body of the walls to be treated, of resins capable of absorb and retain the moisture present in them.

Para ello, se realizan determinadas operaciones, que se expondrán a continuación, acompañadas del empleo de productos específicos.To do this, certain operations are performed, which will be presented below, accompanied by the use of specific products

Detailed description of the invention

El curso de las operaciones que constituyen el nuevo procedimiento puede expresarse como sigue:The course of operations that constitute the New procedure can be expressed as follows:

1º, se extraen muestras de los materiales que forman los muros, a fin de proceder a su examen químico para determinar el tipo y la cantidad de sales contenidas en ellas;1st, samples are taken from the materials that they form the walls, in order to proceed to their chemical examination to determine the type and quantity of salts contained therein;

2º, se prepara una resina base, a base de siloxanos oligoméricos.2nd, a base resin is prepared, based on oligomeric siloxanes.

3º, se procede a la inyección de las resinas de siloxanos oligoméricos, distinguiendo según sea el espesor de los muros a tratar:3rd, the resins are injected oligomeric siloxanes, distinguishing according to the thickness of the walls to be treated:

a) Para los muros de espesor inferior a 70 cm:a) For walls with a thickness of less than 70 cm:

--: se practican taladros de 12 mm. de diámetro y de una profundidad del 80% del espesor de la pared, en una sola cara de ésta, a 15 cm. de altura respecto al pavimento y separados 15 cm. unos de otros;be they practice 12 mm drills. in diameter and a depth of 80% of the wall thickness, on one side of the wall, at 15 cm. from height relative to the pavement and separated 15 cm. some of others;

--: se inyecta la resina del tipo mencionado, empleando una bomba a presión, operando de 4 a 6 bar;be inject the resin of the type mentioned, using a pump to pressure, operating from 4 to 6 bar;

--: se taponan todas las perforaciones mediante mortero.be plug all perforations by mortar.

b) Para los muros de espesor superior a 70 cm.:b) For walls thicker than 70 cm .:

--: se practican taladros de 12 mm. de diámetro y una profundidad del 40% del espesor de la pared interesada, en una sola cara de ésta, a una altura de 15 cm. respecto al pavimento y separados 15 cm. unos de otros;be they practice 12 mm drills. in diameter and a depth of 40% of the thickness of the wall concerned, on one side of it, at a height of 15 cm. with respect to the pavement and separated 15 cm. some of others;

--: se inyecta la resina de siloxano oligomérico mediante una bomba operante a una presión de 4 a 6 bar:be inject the oligomeric siloxane resin through a pump operating at a pressure of 4 to 6 bar:

--: se reperforan los taladros practicados en el paso primero, hasta alcanzar el 80% del espesor total del muro;be they impact the drills practiced in the first step, until reach 80% of the total wall thickness;

--: se reinyecta nuevas cantidades de resina en los taladros anteriores;be reinjects new amounts of resin into the holes previous;

En este segundo caso (a 70 cm.), si el acceso lo permitiera, se podría perforar por las dos caras del muro en en vez de efectuar reperforaciones, excepto en muros de espesor superior a 140 cm. en los cuales siempre será necesario proceder a la reperforación.In this second case (at 70 cm.), If access allowed, it could be drilled on both sides of the wall instead of making reperforations, except in walls thicker than 140 cm in which it will always be necessary to proceed to the reperforation

En una segunda fase, se eliminan los revocos existentes y se realizan otros nuevos:In a second phase, the plasters are eliminated existing and new ones are made:

i)i): se elimina el revoco existente hasta una altura de 30 cm. por encima de la zona visible degradada;be Remove the existing plaster up to a height of 30 cm. above of the visible degraded area;

ii)ii): transcurridos 15 días, se procede a la confección del nuevo revoco:After 15 days, proceed to the Preparation of the new revocation:

a)to): Baño, con agua, de la parte a tratar, y aplicación de una solución antisalina.Bathroom, with water, of the part to be treated, and application of a solution antisaline

b)b): Confección y aplicación inmediata del nuevo revoco macroporoso de alta difusión de la humedad, realizado a base de cal hidráulica natural aditivada o de un mortero macroporoso de base cementicia.Preparation and immediate application of new macroporous high moisture diffusion plaster, made based on additive natural hydraulic lime or mortar cementitious macroporous base.

iii)iii): pintado del nuevo revoco mediante pintura a base de silicatos minerales en vehículo acuoso o a base de pinturas acrílicas.painted the new plaster by mineral silicate based paint in aqueous or base vehicle of acrylic paints.
