Tension Netting Systems Tension netting systems (TNS) are an innovative method of accessing work locations situated in areas such as under deck elements of bridges and piers to jetties and oil platforms. Tension netting systems provide a stable work platform allowing technicians to carryout all manner of work scopes. The system has also been installed as a heavy duty containment system enabling protection to elements below from heavy dropped objects. The containment system maybe installed to capture minute particles increasing up to large and heavy debris created from your desired work scope.

The benefits of these systems are:

• Increased safety margin due to installation by rope access technicians
• Highly portable with minimum storage and transport requirements
• Cost effective when compared to suspended and ‘ground up’ scaffolding
• Lightweight components limiting stress and additional loading to structures including wind loading
• Modular system fitting even the most bespoke spaces
• Reduced man hours due to rapid installation Tension netting systems may be installed to meet one or all of the following requirements:
• Work Positioning or ‘Walk On’ Netting
• Dropped object and containment
• The type of nets used 4x the strength of polypropylene nets manufactured for fall arrest purposes
• Total containment reducing impact to the environment from blasting and painting work scope.

Geckotech have experience in carrying out the following work scope from TNS:

• Inspections and surveys
• Blasting and Painting
• Minor structural repairs

Our Innovative Gecko Encapsulation System (GES) enables personnel to carryout blasting and spraying operations from work positioning nets with no impact to the environment. This combination is a highly cost effective way in which to carryout fabric maintenance in exposed and inaccessible locations.

The Gecko Encapsulation System is an innovative containment system which when used in conjunction with Tension Netting or Decking Systems provides the worker with a comfortable and controllable working atmosphere for grit blasting and coating work scope whilst the environment and surrounding area remain unaffected by waste or bi-products. The correct application of the Gecko Encapsulation System can benefit our clients in the following ways:

• Containment of air borne particles such as over spray and blast media 
• Positive and Negative pressures are achievable
• Reduction in clean up and waste management costs
• Environmental protection
• All the benefits of Tension Netting and Decking Systems
• The introduction of effective humidity control for coating applications. Geckotech technicians can achieve a relative humidity of 40% and below. This can be maintained retarding the corrosion process.

Each individual area requiring the system will be surveyed and a bespoke system designed and produced. The encapsulation system is constructed from high quality materials easily capable of withstanding the daily abuse from prevailing weather conditions and any of the following tasks:

• Grit Blasting and Spraying
• Hot works
• Minor Construction Works
• Work scope requiring particular atmospheric conditions and full containment properties

Geckotech Solutions have a working model of the Gecko Encapsulation System at our office, where we can carry out a live test to demonstrate the systems effectiveness right in front of your eyes. Please contact us to arrange a visit.
