Our inversion hose or calibration hoses are manufactured in several grades of PVC coated reinforced polyester fabric dependent on size and application. The high tenacity flexible PVC ranging from 400 –  900 grams per m² is of superior quality and available in a wide range of diameters. Calibration hoses can either be made to measure for a particular project or produced in standard diameters and lengths up to 500m for stock hoses.

Our ambient-cure hoses are usually ‘high-frequency weld only’, both down the longitudinal joint and round any traverse joints. The hot-cure Heavy Duty hoses, which are used in hot-cure applications, are both welded and stitched along each joint. Our unique method of production of these hot-cure hoses gives the maximum joint strength and ensures the stitching affords the greatest possible level of protection against softening of the PVC as the temperature rises.

In addition to these standard calibration hoses we also manufacture a number of custom supplied hoses and no-dig hose accessories in a range of different materials including polyurethane and translucent PVC.

If you have specific development requirements for new processes/materials, please do contact us as we have significant experience in undertaking development work in this area and continue to work closely with our clients to provide calibration hoses for more specialised applications.
