Definitions

  • the present invention relates to gas proofing, waterproofing and- other liquid proofing, and sealing generally. Specifically, the invention is concerned with a material that both provides a barrier and facilitates drainage.
  • barrier materials are manufactured from many different types of materials and are produced in discrete widths. The barrier materials are commonly supplied on rolls of suitable length for transport and installation.
  • the degree of impermeability of the barrier material depends, in the first instance, on its composition and the quality of the installation, hi addition, it is also dependent on the pressure head or hydrostatic head on either side of the barrier material. Thus, the greater the pressure which is applied, the more likely it is that the gas, liquid or solid will pass through the barrier. Thus, the control or reduction of the pressure head or hydrostatic head is of great importance.
  • the escape of gas, liquid or solids through the barrier material is anticipated and a void is provided which acts as a leak detection layer or escape route alongside the barrier layer.
  • Barrier materials of the type described may either be used alone, or in conjunction with at least one of a geotextile, which provides protection, or a geocomposite drain, which facilitates removal of liquid and/or gas, and allows for control of the hydrostatic head or pressure head on the barrier material.
  • a geotextile which provides protection
  • a geocomposite drain which facilitates removal of liquid and/or gas, and allows for control of the hydrostatic head or pressure head on the barrier material.
  • the individual layers of barrier material, geotextile and/or geocomposite drain are each installed in separate operations.
  • the drainage layer may consist of any of a number of different forms, but generally has a geonet or cuspated core structure.
  • the barrier material preferably comprises a textured surface on one or both sides, which provides increased friction (shear strength) with an adjacent layer.
  • the smooth roll edges which are manufactured without texture
  • the textured barrier material cannot be joined together to form impermeable joints by use of a hot air/wedge welder, or by means of ultrasonics, unless the texture is first removed by grinding. Consequently, there are difficulties in providing large areas of the material.
  • An alternative arrangement which was • developed some time ago for several applications comprises the bonding of the protective geotextile to the geomembrane or waterproofing barrier material before delivery to site, thereby eliminating the cost and time of a separate installation, as well as increasing the shear strength between layers, even with smooth geomembrane or waterproofing barrier materials. Bonding of the geotextile to the barrier material is omitted along the roll edges in order to enable the joining of the individual rolls into larger areas by any of the known methods. However, it is not possible to form impermeable joints other than at the roll edges in view of the bond between the geotextile and the geomembrane barrier.
  • a still further development for structural and landfill applications is that of a geomembrane or waterproofing barrier material with solid projections of various shapes on one or both sides.
  • said material comprises a thermoplastic material, since such materials readily facilitate formation of the projections.
  • This material combines the functions of barrier and drainage provision when used in conjunction with a geotextile filter or separator that is laid separately over the projections on at least one side of the material.
  • the geomembrane or waterproofing material is manufactured without projections along the roll edges so that it is possible to join individual rolls together to form larger areas. However, it is not possible to join the rolls to form impermeable joints at any major angle other than parallel or perpendicular to the roll edges, or at any point other than at the roll edges, without preparatory grinding to remove the projections.
  • the preformed barrier materials of the prior art typically comprise a solid plastic layer on which are disposed plastic projections or textures which are designed for friction, or tp facilitate a flow of liquid and/or gas.
  • these materials cannot be joined to form impermeable joints at any angle other than perpendicular or parallel to the roll length without prior preparation.
  • the present inventor has shown that by providing a material in accordance with the present invention, the said material can be adapted to fulfil both the barrier and drainage function and, optionally, may comprise at least one geotextile that can be peeled away easily but has good interface shear strength and/or friction, and is firmly but releasably attached, wherein the said material may be welded in various dispositions other than the edge-to-edge disposition disclosed in the prior art, whilst still maintaining the integrity of the drainage and/or barrier functions.
  • a material for use in waterproofing or containment of liquids, gases or solids comprising a layer which comprises an impermeable or a semi permeable barrier and is adapted to facilitate drainage, wherein said material comprises a geomembrane or waterproofing barrier material comprising a plurality of voids which facilitates drainage, said plurality of voids being provided by means of a layer which comprises a cuspated layer, said cuspated layer comprising a plurality of cusps, wherein said cusps are adapted so as to facilitate the joining of the edges or cuspated parts of said material to the cuspated parts of said material at any angle, said cusps having a shape and being located in a position on said material so as to facilitate said joining.
  • Said plurality of cusps comprises a plurality of indentations on one side of the layer.
  • Said cusps may be cylindrical, frustoconical, truncated tetrahedral or any hollow shape.
  • Said indentations appear as protrusions on the opposite side of the said layer.
  • the cusps may be arranged to project as protrusions on one side of the plane of the said layer or, optionally, can be arranged such that indentations and protrusions are observed on both sides of the said layer.
  • the cusps protrude from the surface of said layer to a distance of between l mm and 15 mm.
  • the present invention envisages situations wherein the edges or cuspated parts of a sample of the material of the invention may be joined to the cuspated parts of the same sample of said material. Preferably, however, the edges or cuspated parts of a sample of the material are joined to the cuspated parts of at least one other sample of said material.
  • the material of the invention comprises cusps and other additional features adapted so as to facilitate the joining of the edges or cuspated parts of the said material to the cuspated parts of the said material at any angle, said cusps and other additional features having a shape and being located in a position on said material so as to facilitate said joining.
  • Said other additional features may comprise, for example, small ridges, grooves or projections.
  • the material according to the first aspect of the invention preferably comprises a plastics material, preferably a thermoplastic or thermoset plastics material, most preferably a polyolefin such as polyethylene or polypropylene.
  • the weight of the cuspated layer is in the range of from 300 to 3000 g/m 2 of material.
  • Said material is capable of being joined at its edges to its other edges or to a separate geomembrane/waterproofing material in a manner that provides continuity and allows for the formation of an effective barrier and drainage facility.
  • Joins between samples of material according to the first aspect of the invention may be formed by welding, extrusion, heating, application of tape or adhesive, ultrasonics, and the like.
  • said joins are formed by the action of a hot air/wedge welding machine.
  • said joins can be formed by means of a twin weld comprising a test channel by means of which the integrity of the joins can be determined.
  • the material according to the invention additionally comprises at least one geotextile.
  • Said geotextile is releasably attached to said material.
  • Said releasable attachment is preferably achieved by means of an adhesive.
  • Preferred adhesives in this context include, for example, hot melts of EVA, rubber or polyolefins.
  • releasable attachment of said geotextile to said material may be achieved by means of a material of similar chemical characteristics to the material of the invention, such that remaining material on the material of the invention after release does not impair the joining of the said materials.
  • a method for the formation of a barrier material comprising:
  • joins at the stated locations is carried out by means of welding, extrusion, heating, application of tape or adhesive, ultrasonics, and the like.
  • said joins are formed by the action of a hot air/wedge welding machine.
  • Said joins may be formed by means of a twin weld comprising a test channel by means of which the integrity of the joins can be determined.
  • the method according to the second aspect of invention provides a barrier material wherein the welds are formed with cuspations, grooves or ridges such that the drainage is maintained across and/or along the join.
  • the combination of barrier and drainage features provided by the material according to the first aspect of the invention serves to reduce or control the pressure head or hydrostatic head on the said material, such that the transmission of gas, liquids or solids from one side of the said material to the opposite side of the material is greatly reduced in comparison to the effect achieved with a flat geomembrane or waterproofing barrier formed from the same material.
  • the equivalent effect may be achieved with material of the invention which is thinner than a comparable flat geomembrane or waterproofing barrier, since the material of the invention can provide the same rate of transmission of gas, liquid or solid from one side of the material to the opposite side, as may be achieved with a significantly thicker flat barrier.
  • the combination of a barrier and a plurality of voids provided by the material of the invention additionally serves to provide space above or below the barrier in which any leakage of gas, liquid or solid through the barrier may be identified, isolated and, if necessary, removed.
  • the cuspated layer may be formed with flat areas along its edges, wherein said flat areas do not comprise cusps.
  • said layer may comprise cusps to the very edges of the layer.
  • the shape of the cusps which may be comprised in the material according to the first aspect of the invention is adapted such that the said cusps deform readily at elevated temperatures which are generally created by the method of joining, which preferably involves the application of heat or ultrasonic waves.
  • an essentially flat layer is formed in the region of joining, such that a join may readily be formed. This flattening of the cusps may be performed prior to, or at the same time as, the actual joining process.
  • the shape and arrangement of the said cusps is such that the cusps comprised in one sample of the material according to the invention may engage with the cusps comprised in another sample of the material according to the invention, thereby securing the separate samples of material relative to each other such that no slippage occurs during the joining process.

  • the method utilises a hot air wedge welding machine with at least one roller shaped to form a cuspated profile or ridges or grooves. Additionally, it is preferred that the at least one roller provides the driving force to propel the welding machine.
  • the method requires a welding machine which comprises a set of rollers shaped to form the cuspated profile, ridges or grooves and a separate set of driving rollers to propel the welding machine.
  • the said driving rollers operate outside of the weld, such that there is no shear stress on the weld area due to the propulsion of the welding machine.
  • the method utilises a welding machine adapted so as to automatically separate any geotextile that is releasably attached to the material according to the first aspect of the invention, maintain said geotextile in a location clear of the welding zone, and additionally re-attach said geotextile to the material of the invention after the welding process has been completed.
  • the preferred welding method comprises arranging one or more pieces of the said layer to overlap each other in a uniform manner.
