Description

2340070 WATERPROOFIRG MEMBRANES AND A METHOD FOR THEIR APPLICATION.
Field of the Invention This invention relates to membranes for the waterproofing of materials used in building construction and civil engineering projects and to a method of their application.
Background of the Invention Previously waterproofing materials have been post applied to an existing structure which is typically of concrete.
Problem to be solved by the Invention There is a need for a waterproofing membrane that can be pre-applied to vertical formwork or a horizontal surface and adhere strongly to post cast concrete. A solution to this problem has been proposed in European Patent No 501,838 which describes a waterproofing membrane comprising (i) a carrier layer for disposition against a concrete form, (ii) a layer of a defined pressure sensitive synthetic adhesive disposed on one face of the carrier layer and (iii) a protective coating layer disposed upon the synthetic adhesive layer. The membrane is said to bond without the need for tackification to concrete applied against the protective coating. However, because of the characteristics of the materials used for the protective coating, the membranes described in this patent are not suitable to be left exposed on site for extended periods of time. This can be significant if there is a delay in the construction programme. The present invention provides a solution to this problem.
Summary of the Invention.
According to the present invention there is provided a waterproofing membrane comprising (i) a first layer in the form of a sheet of thermoplastic polymer suitable for application to a formwork, the first layer having bonded thereto (ii) a second layer made from a thermoplastic polymer and having a structure that provides a keying formation capable of keying into concrete cast against the second layer.
According to another aspect of the present invention a method of waterproofing structures comprises (i) applying to a formwork a waterproofing membrane as defined above so that the first layer is against the formwork and then (ii) applying fresh concrete against the second layer of the membrane and allowing the formation to key into the concrete and the latter to set.
Advantageous Effect of the Invention The membrane of the invention is capable of withstanding longer periods of exposure without significant deterioration, for example greater than 30 days between application to the formwork and the pouring of the concrete.
Brief Description of the Drawings
Fig 1 is a plan view of the membrane and Fig 2 is a partial cross section taken on the line A-A of Fig 1.
Fig 4 is a plan view of an alternative embodiment and Fig 4 is a cross section taken on the line B-B of Fig 3. The drawings are not to scale. The measurements are in mm.
Detailed Description of the Invention
The first and second layers are preferably composed of a thermoplastic polymer, more preferably a hydrocarbon polymer such as an olefin eg an alpha olefin and preferably an olefin containing from 2 to 6 carbon atoms. Examples are polyethylene or polypropylene. A medium density polyethylene is particularly suitable although high and low density polyethylene are also suitable. Other thermoplastic polymers which may be used include polyethylene terephthalate, polystyrene, polyvinyl chloride, polyamides, or combinations thereof. The thickness of the first layer may be from 0.05 mm to 1.0 mm (0.002 to 0.039 inches). The first and second layers may be composed of the same or different polymers. When different polymers are used for the first layer and the grid they are preferably selected so that the two layers can be hot bonded together. Particularly suitable polymers for the first and second layers are polyethylene or polypropylene. The keying formation of the second layer may be provided by a raised formation or rib-like structure. Preferably a plurality of formations are provided, more preferably arranged in a regular pattern. Conveniently there is provided a plurality of straight parallel formations which intersect another plurality of similar straight parallel formations to provide a series of diamonds or squares or other quadrilateral. The intersecting formations provide a structure which will hereafter be referred to as a grid. The second layer may be in the form of a sheet having the formations attached thereto. Alternatively and preferably the second layer is provided by the grid ie it has no sheet. The second layer may be capable of being formed into a roll. The apertures in the grid may be from 1 square mm. to 625 square mm preferably from 5 square mm to 100 square mm. The apertures may be square or diamond shaped although other shapes are suitable. Preferably the size of the formations provided by the grid is such that when keyed to the concrete a cellular structure is provided. The advantage of this is that water tracking between the membrane and concrete face is prevented or reduced in the event that the membrane is holed in one place. A particularly suitable grid is one sold by Netlon Limited for use in soil stabilisation. The membrane may be provided with an adhesive edge portion eg a strip for bonding to an overlapping membrane. This is conveniently in the form of a tape which is applied to the edge of the membrane sheet and which may be made of a bituminous or synthetic adhesive. Production of the waterproofing membrane. The first layer in the form of a polyethylene sheet is manufactured by horizontal slot die extrusion which is a process known in the art. The hot sheet leaving the extrusion process passes via a conveyor through callendar rollers which are calibrated to produce a predetermined final sheet thickness. The sheet and the polyethylene grid are together fed into "nip rollers" which are preheated and exert a light pressure. The result is the lamination of the two together. The product then passes down the conveyor through cooling rollers and is then wound into rolls. Referring to Figs 1 and 2: the membrane indicated generally by reference numeral 1 comprises a polyethylene grid 2 comprising of a set 3 of straight formations and another set 5 of straight formations. The two sets of formations 3 and 5 intersect at right angles and are bonded to each other. Formations 3 are proud of formations 5. Each of the sets of parallel formations has ten formations of similar size spaced at regular intervals of six (6) mms, then two formations of double the height spaced ten (10) mms apart, then another ten (10) uniformly spaced formations of the same size as the first ten. The larger sized formations 7 and 8, 9 and 10, 11 and 12, 13 and 14 form a large diamond or square and are shown in Fig I. The larger formations form a cell when they key into the concrete of the second pour which will reduce the risk of water tracking between the membrane and concrete of the second pour. The grid 2 has been bonded to a medium density polyethylene sheet (not shown in Figs 1 and 2). An edge portion 19 ( a strip 68mm, in width) of the sheet is not covered by the grid but is provided with adhesive and a silicone release paper. The purpose of the adhesive edge strip 19 is to provide bond between adjacent membranes when laid in overlapping relationship.
Referring to Figs 3 and 4: the embodiment shown in these drawings does not have the larger formations and the adhesive edge strip is slightly wider at 75mm. The membrane comprises a medium density polyethylene sheet 24 of 0.8mm thickness to which is bonded a polyethylene grid 22. The grid 22 comprises two sets of parallel formation 23 and 25 which intersect and are bonded to each other. Formations 23 are proud of formations 25. An edge strip 29 of the sheet 24 is not covered by the grid but is provided with adhesive 30 and a silicone release paper 32. In use the membrane is applied to a formwork (not shown) which may be vertical or horizontal, with the polyethylene sheet in contact with the formwork and fixed eg by nails. The individual membranes are laid with the adhesive edge strips overlapping and providing a bond between adjacent sheets. Then newly mixed concrete is poured so that it contacts the grid and allowed to set. The grid keys into the concrete and provides a robust structure. The peel adhesion of the key provided by the present invention was found to be 2950N/m (ASTM D903 modified). This compares with a value of 88ON/m (ASTM D903 modified) for the membrane according to European Patent No 501838.
