Definitions

  • the present invention relates a method for reducing moisture build-up in a cavity of a cavity wall of a building.
  • the invention also relates to a foundation wedge to be placed in the cavity between an outer wall and an inner wall.
  • the invention further relates to a system for preventing encroachment of moisture into areas where foundations and walls in a building meet.
  • the invention relates to a building having one or more walls comprising such foundation wedges and/or such a system.
  • a building is normally erected by constructing an insulated foundation and subsequently placing external and inner walls and placing the roof structure of the building so that it is carried by at least the external walls.
  • the external walls normally comprise an outer wall and an inner wall.
  • the outer wall is the outside of the building and constitutes the building envelope of the building, and the inner wall is placed against the inside of the building. Between the outer wall and the inner wall is a cavity which can be filled with insulation material.
  • the expressions outer wall and inner wall should not be taken to mean that these are necessarily masonry walls, as the front and inner walls can also be manufactured from the traditional materials used for inner and outer walls in buildings, such as wooden cladding, plates based on wooden material, e.g. plywood, so-called OSD boards, woodchip boards, MDF boards and similar boards, gas concrete, concrete, bricks, plasterboards etc.
  • the outer wall and/or the inner wall may be load-bearing for floor decks and/or roof structure, or the external walls may comprise a load-bearing framework of posts made from concrete, reinforced concrete, wood, metal, including steel or light-alloy metal such as aluminium or similar.
  • the load-bearing framework will be cladded by a facade material of a generally known type, constituting the building envelope of the external walls and comprising an inner wall, e.g. in the form of a plasterboard cladding or similar materials which are normally used for inner wall cladding in a building.
  • a risk may occur of condensate forming in the cavity between the inner wall and the outer wall.
  • any intruding water may run into the cavity between the outer wall and the inner wall. This water will typically collect in the bottom of the cavity between the inner wall and the outer wall and may spill out over the foundation at outer wall, but there is also a large risk that the moisture penetrates the building in the area at the joint between the inner wall and the foundation. This leads to moisture arising in the area, which may result in growth of mildew and/or moulds, which are unwanted in all types of buildings, as they may pose a health risk for the people residing in the building.
  • An object of the invention is to prevent intruding water, condensate and other moisture which collects at the bottom of the cavity between the outer wall and the inner wall in a cavity wall, particularly an external wall, from penetrating into a building in the area where the wall and the foundation meet.
  • the invention relates to a method for reducing moisture build-up in a cavity of a cavity wall of a building.
  • the method comprises the steps of claim 1.
  • Arranging the water impermeable sheet so that it extends all the way from the inner face of the inner wall and out to the outer side of the foundation and so that it at the same time inclines downwards in the same (outwards) direction is advantageous in that it hereby is ensured that moisture - e.g. condensed water forming on the inside of the outer wall - building up at the foundation in the cavity is guided efficiently out of the building.
  • building the outer wall on top of the water impermeable sheet - so that the water impermeable sheet extends all the way beneath the outer wall - is advantageous in that it ensure more efficient drainage of fluid from inside the cavity and out under the outer wall.
  • the water impermeable sheet could be formed by any suitable flexible sheet or foil material such as any kind of Polyethylene (PE) foil, rubber, synthetic rubber, thermoplastic, asphalt material, bitumen, modified bitumen or other or any combination thereof.
  • PE Polyethylene
  • the method comprises arranging a wedge-shaped element between the foundation and the water impermeable sheet in the cavity.
  • Placing a wedge-shaped element under the water impermeable sheet is advantageous in that it helps maintaining the inclined shape of the water impermeable sheet.
  • the wedge-shaped element is pre-attached to the water impermeable sheet before arranging the water impermeable sheet in the cavity.
  • the wedge-shaped element is formed from a thermal insulating material.
  • Forming the wedge-shaped element from a thermal insulating material is advantageous in that the risk of the wedge-shaped element acting as a thermal bridge between the inner and outer wall is hereby reduced.
  • thermal insulation material any material capable of significantly lowering the thermal conductivity in the wedge area i.e. typically between the outer wall and the inner wall.
  • thermal insulation materials include any kind of material having a low thermal conductivity i.e. typically below 0.5 watts per meter kelvin (W ⁇ m-1 ⁇ K-1) such as mineral wool or foam, polymer-based insulation materials - such as expanded or foamed polystyrene (PS), polyurethane (PU, PUR), polyisocyanurate (PIR), polyethylene (PE), polypropylene (PP) - ceramic insulation tiles, glass foam or other and/or any combinations hereof.
  • PS expanded or foamed polystyrene
  • PU polyurethane
  • PUR polyisocyanurate
  • PE polyethylene
  • PP polypropylene
  • the water impermeable sheet is arranged in an angle A of between 1° and 80°, preferably between 2° and 60° and most preferred between 3° and 35° in relation to a plane perpendicular to the inner face of the inner wall.
  • the present angle ranges presents an advantageous relationship between cost and efficiency.
  • the water impermeable sheet is connected to the inner face of the inner wall.
  • Connecting the water impermeable sheet to the inner face of the inner wall is advantageous in that it ensures a more uniform and precise installation.
  • the water impermeable sheet is arranged to extend along a part of the inner face of the inner wall in a direction away from the foundation.
  • Arranging the water impermeable sheet so that it abuts the inner face of the inner wall over a certain distance is advantageous in that this contact zone enables secure fixation and reduces the risk of ingress of water to the underside of the water impermeable sheet.
  • joint sealant and/or adhesive is arranged between the water impermeable sheet and the inner face of the inner wall.
  • Providing joint sealant and/or adhesive between the water impermeable sheet and the inner face of the inner wall is advantageous in that it ensures good fixation and reduces the risk of ingress of water to the underside of the water impermeable sheet.
  • the method further comprises the step of covering posts, beams, pipes or other elements extending from the foundation in the cavity and into the cavity with a covering profile.
  • Covering these elements in a covering profile is advantageous in that the risk of these elements acting as a thermal bridge between the inner and outer wall is hereby reduced. Furthermore the risk of water condensing on these elements is reduced.
  • the covering profile comprises at least two or preferably at least three side pieces, wherein the side pieces are connected by an integral hinge.
  • Connecting the side pieces of the covering profile by integral hinges is advantageous in that it reduces production costs and ensures simple logistics. And arranging hinges between the side pieces is advantageous in that it enables simple and precise mounting on the element.
  • integral hinge should be understood as an area at which the profile has a tendency to bend. I.e. an internal hinge not a separate part from the profile but is formed as an integrated part of the profile - e.g. by forming longitudinal bending zones along which the profile will be able to bend back and forth (as a hinge) when subject to a force.
  • the covering profile is made from a thermal insulating material.
  • making the covering profile comprise a thermal insulating material is advantageous in that the risk of these elements acting as a thermal bridge between the inner and outer wall is hereby further reduced. Furthermore the risk of water condensing on these elements is further reduced.
  • the method further comprises the step of covering a transition zone between the water impermeable sheet and posts, beams, pipes or other elements extending from the foundation in the cavity and into the cavity with collar means.
  • Forming collar means in the transition zone is advantageous in that it reduces the risk of ingress of water to the underside of the water impermeable sheet.
  • collar means should be understood as an any kind of flashing, covering, bandage or other form of collar suited for covering a transition zone between a water impermeable sheet and posts, beams, pipes or other elements.
  • joint sealant and/or adhesive is arranged between the collar means and the water impermeable sheet and/or between the collar means and the posts, beams, pipes or other elements.
  • Arranging joint sealant and/or adhesive between the collar means and the water impermeable sheet and/or between the collar means and the posts, beams, pipes or other elements further reduces the risk of ingress of water to the underside of the water impermeable sheet.
  • the collar means are made from the same material as the water impermeable sheet.
  • Forming the collar means and the water impermeable sheet from substantially the same material is advantageous in that it simplifies installation and logistic and it reduces cost.
  • the invention further relates to a foundation wedge, comprising a wedge-shaped element having an underside, a side face and an oblique upper side, and wherein the wedge-shaped element is manufactured from an insulation material, the wedge-shaped element being covered by a water impermeable sheet that extends beyond at least two of the parallel edges of the upper side.
  • An object of the invention is further achieved using a system to prevent encroachment of moisture into areas where foundations and walls in a building meet.
  • the building comprises a foundation and walls located on the foundation, the walls comprising a outer wall and a inner wall placed at a distance from the outer wall.
  • the system comprises the foundation wedge, which is located along the inner wall on the surface of the foundation in the cavity between the outer wall and the inner wall, and the water impermeable sheet of the foundation wedge has been led some distance up against the inner wall and out over the foundation and under the outer wall.
  • the width of the water impermeable sheet By letting the width of the water impermeable sheet be bigger than the width of the wedge element, it is achieved that the water impermeable sheet can be laid some distance up against the inner wall and over the foundation and under the outer wall. It can thus be avoided to lay the traditionally used strip of water impermeable sheet under the outer wall, as the water impermeable sheet of the foundation wedge can replace this.
  • the foundation wedge is typically placed in the gap after the erection or manufacture of the inner wall, and before the outer wall is erected or manufactured.
  • the foundation wedge can thus be used both in connection with in situ erection of a building, but can also be used in pre-fabricated wall elements manufactured at the factory and transported to the construction site and erected.
  • the wedge-shaped element is according to the invention fixed on the water impermeable sheet, preferably by glueing, as this makes it easier to handle the foundation wedge and thus also quicker to mount it correctly. It is also possible to use the foundation wedge as two spare parts placed individually when erecting the external wall.
  • the wedge-shaped element has a rectangular ground plan, wherein the cross-section perpendicularly to the longitudinal direction of the wedge-shaped element is wedge-shaped, the oblique upper side extending from the side wall in the longitudinal direction along the one longitudinal side of the rectangular ground plan to the pointed edge along the other longitudinal side of the rectangular ground plan.
  • Suitable insulation materials are commonly used in construction and are e.g. rock wool, glass wool, polymer-based insulation materials, such as expanded or foamed polystyrene (PS), polyurethane (PU or PUR), polyisocyanurate (PIR), polyethylene (PE), polypropylene (PP) and/or combinations thereof. It is preferred that the insulation material is pressure-resistant, e.g. pressure-resistant rock wool, as the wedge-shaped element is thus dimensionally stable and does not lose its wedge shape during transport, handling and/or mounting.
  • PS polystyrene
  • PU or PUR polyurethane
  • PIR polyisocyanurate
  • PE polyethylene
  • PP polypropylene
  • the water impermeable sheet of the foundation wedge is manufactured from felt board, wall board, foil and/or combinations thereof.
  • Felt board and wall board are commonly known building materials and consist of a fibrous layer, most often made from synthetic fibres, coated with layers of bitumen or a mixture of bitumen and synthetic rubber which normally cover both sides of the fibrous layer.
  • Suitable foils are also known from the construction industry and are e.g. made from polyethylene (PE), low-density polyethylene (LDPE) or rubber-based foils, such as ethylene propylene diene rubber (EPDM), which are also used in the construction industry.
  • PE polyethylene
  • LDPE low-density polyethylene
  • EPDM ethylene propylene diene rubber
  • a joint or an adhesive is placed between the top edge of the water impermeable sheet and the inner wall.
  • the joint e.g. mastic sealant, acrylic sealant or silicone sealant, is preferably laid manually between the water impermeable sheet and the inner wall in connection with the mounting of the foundation wedge.
  • the foundation wedge is manufactured with an adhesive strip along one or more edges of the water impermeable sheet and at least along the side of the edge which is intended to abut the inner wall.
  • the adhesive strip is preferably covered by a protective strip, which is torn off before the adhesive strip is pressed against the inner wall.
  • the adhesive strip at one end is placed on the opposite side of the water impermeable sheet in relation to the above-mentioned adhesive strips. Any further adhesive strip at the other end of the water impermeable sheet of the wedge element is placed on the same side of the water impermeable sheet as the adhesive strips along the longitudinal sides of the water impermeable sheet. This makes it possible to adhere the water impermeable sheets of several foundation wedges together in continuation of each other, so that they constitute an overall surface for the entire length of the wall.
  • a tape roll is used, which is adhered over the joints between the individual pieces of water impermeable sheet, or an adhesive is used, which is applied to one or both layers of water impermeable sheet in an overlap between two water impermeable sheets on to foundation wedges placed in in continuation of each other in the cavity between the front and inner wall.
  • the system according to the invention preferably comprises a covering profile for covering posts and/or doors placed in the wall.
  • the covering profile comprises a U-profile with perpendicular flanges along one end of the U-profile.
  • the U-profile itself thus covers the post or the frame at the door, and stands on the flange on the foundation.
  • the U-profile is preferably manufactured from plastic, so that no thermal bridge occurs in the wall where the U-profile is mounted. It is possible to cut a triangle out of the U-profile and the corresponding lower flange in the area which abuts the wedge element of the foundation wedge, corresponding to the triangular cross-section of the wedge element, so that the U-profile can be placed around the post after the foundation wedge has been located in the cavity in the wall.
  • the covering profile is a substantially U-shaped profile made from hard plastic, such as polyethylene (PE), polypropylene (PP) or polyester/polyethylene terephthalate (PET) and/or combinations thereof, and has a sufficient material thickness to make the U-profile flexible, so that it can easily be mounted around the post while at same time being self-supporting.
  • hard plastic such as polyethylene (PE), polypropylene (PP) or polyester/polyethylene terephthalate (PET) and/or combinations thereof
  • the covering profile comprises at least two or preferably at least three side pieces made from an insulating foam-shaped material, wherein the side pieces are connected by an integral hinge.
  • the covering profile is manufactured from foamed plastic, e.g. PE plastic foam, e.g. by extrusion, and is adapted to the form of the posts as detailed below.
  • a particularly suitable plastic foam is a cross-linked PE plastic foam with closed cells.
  • the plastic foam covering profile adapts easily to the form of the posts, as the material is flexible. There is therefore no need for major precision during the manufacture of the covering profiles.
  • the outer surface of the covering profile will preferably have a square or rectangular form, so that it is easy to fix the water impermeable sheet of the foundation wedge to the surface of the covering profile.
  • the covering profile in addition to serving as a substructure for fixing of the water impermeable sheet of the foundation wedge, as described above, can also insulate the post, so that the risk of thermal bridge occurring at the posts is reduced or completely avoided, and any problems arising as a result of condensate issues arising in the cavity between the outer and inner wall are eliminated or at least reduced significantly.
  • This variant of the covering profile can be used to cover vertical post profiles as well as horizontal beam profiles and also other profiles built into a wall in a building.
  • the invention further relates to a wall, a wall element and/or a building comprising one or more walls with a foundation wedge or a system according to the invention.
