SISTEKO : Polyester shafts
Concrete sewage shafts are increasingly substituted for our shafts made of reinforced polyester (GRP). This is a material reinforced with glass fibres, which are distinguished for flexibility and resistance to corrosion.
GRP polyester sewage shafts are a high quality, practical and functional solution for draining of waste waters of all kinds – faecal, industrial or surface in origin – economical in the long term. Each shaft is manufactured according to a specific design matched to the field situation.
Advantages of our shafts
• High load bearing capacity with small specific weight
• Totally impermeable to water and non-porous
• Superbly smooth internal surface layer
• High chemical stability
• High resistance to erosion
• Simple pipe joining, i.e. shorter shaft installation times
• Low maintenance costs
• Low transport costs
• Highly efficient sealing of pipe to shaft joints
• Appropriate flexibility and geometrical stability, resistance to
damages caused by soil movement
• Guaranteed shaft quality in any application
• Long service life
Shafts are made in different designs and dimensions, according to our customers’ requests
• classic revision shafts
• tangential shafts
• settling shafts
• relief shafts
• sinkholes / sand traps
