Limits vertical structural displacement due to freeze-thaw cycles

• Soleno’s smooth exterior manholes can be perfectly tailored for infrastructure repair work and designed according to your specific requirements for new installations.
• The manhole’s diameter can be the same as that of the connections, which prevents oversizing it, at the same time lowering the cost of the whole system.
• Much lighter than traditional manholes, they facilitate on-site installation.
• Smooth exterior manholes eliminate the need for frost-resistant geocomposite. As they are made from HDPE, they provide excellent resistance to de-icing salts, abrasives, chemicals and vibration.
• Withstands CL-625, H-25 and HS-25 loads.
