Masterlay 2000 system The Masterlay 2000 system lies at the forefront of rapid installation techniques for polyethylene, geosynthetic and composite liner systems. Developed initially to compliment waste management associated earthworks activities and in recognition of the desirable linkage between earthworks and lining productivity, the Masterlay 2000 system now has applications in not only landfill Cells and Capping but also groundwater protection schemes, irrigation, reservoirs, lagoons and such like. The Masterlay 2000 system comprises a hydraulic laying frame operating from a normal three point linkage on an agricultural tractor with two spool valves. This is standard equipment on the majority of tractors. The simplicity of the system is such that it is not necessary to utilise expensive modern tractors in order to successfully implement the installation technique. Instead, a four wheel drive unit of around 100HP and up to ten years in age is satisfactory for this application.
	The rolls of liner are held rigidly within the laying frame by virtue of a high strength aluminium tube. Two tubes are utilised during the installation process. Whilst deployment takes place the second tube is sleeved through the next liner roll ready for use. The integral quick release system enables the spent tube to be discharged and the new roll engaged in a matter of seconds. The ability of the tractor and frame to rapidly traverse the site and reload are instrumental in achieving outputs of up to 2700sq.m per hour.
	The installation equipment itself is width extendable. Two variants are currently available, the first accommodating rolls of 4.30 - 6.75m width. This was developed specifically for use with GCL products and coincides with the maximum roll widths presently available. It is however, compatible with and can be used to lay any 'rolled' material up to 1.00m diameter. The second and more substantial frame has been developed for use with polyethylene liners and has been successfully utilised on rolls up to 9.40m width and 2tonnes in weight. This equipment replaces the aluminium tube with hydraulic 'wings' which are used in the process of engaging and discharging the rolled material. It also has a braking system so that the liner may be pulled tight when it is being deployed.
Built in safety controls are further key features of the Masterlay 2000 system. The use of lightweight aluminium lifting bars eliminates manual handling issues. The liner roll is also held rigidly within the frame and at no more than 1.00m above ground level, hence there is no tendency to 'swing'. The Masterlay 2000 system has a proven and successful track record on both substantial liner installation projects and minor schemes alike. The competitive installation rates available coupled with outstanding productivity give rise to not only significant cost savings but also reductions in overall works programme. This unique application also gives the operator total control over the forming of minimum laps and hence reduces wastage to a negligible level. In areas of poor quality formation, low ground pressure tyres may be used in order to maintain the integrity of the formation layer. The versatility of the Masterlay 2000 system is such that it can be used on surfaces sloping at gradients of up to 1:2.5. The combination of the foregoing benefits has given rise to the Masterlay 2000 system position as the installation technique recommended by many of the worlds leading manufacturers of polyethylene and geosynthetic liners. The Masterlay 2000 system is offered with a full UK & overseas installation service and world-wide franchise opportunities. It is also the subject of UK, Ireland, USA and Canadian patents.
