Structural Waterproofing Nonwoven Fleece Membrane
Our superabsorbent fabrics are used in the construction industry for structural waterproofing applications. Their self-healing properties give a cost-effective extra layer of protection against below grade water entry.
When adhered to an HDPE membrane, our fleece Needlepunch Fabrics – a blend of our very own Super Absorbent Fibres (SAF™) and other fibres types – are used as a Type A solution within structural waterproofing applications.
These fabrics add an extra self-healing layer of insurance against water ingress for below ground level structures, e.g. basements and underground car parks. Should the HDPE membrane be breached, the self-healing properties in the fleece results means it will swell upon contact with groundwater and block and holes. This stops any further water from entering the structure. Our fabrics are already being used in such end products that are compliant to BS8102. Furthermore the gel formed when the fabric is applied to the concrete seals the surface.
Our technology can also be used in products that need to satisfy BS 8485 to protect against the penetration of ground gases, specifically methane, CO2 and radon.
Needlepunch
Needlepunch Nonwovens Engineered to Perform
Needlepunch Fabrics (also referred to as Needlefelts) are exactly that – fabrics that are bonded together by needling. Needling provides a great deal of flexibility and, as a result, such fabrics can be designed to offer high levels of strength and integrity or to be soft and very loosely bonded.
We can manufacture Needlepunch Fabrics at relatively small MOQ’s, with or without SAF™, at a range of weights between 150-1,000gsm. If you require absorbency, up to 80% SAF™ content can be achieved. Laminates and other finishes are possible.
All our Needlepunch Fabrics are supplied either direct by us or one of our trusted global tolling partners. They are sold on rolls at widths of up to 2m and can be slit narrower if required. We have a large selection of off-the-shelf Needlepunch solutions available and can also engineer bespoke fabrics where commercially viable.
