Infra-riser installation for Georgia DOT evaluation

Advantages of the Infra-riser

• Reduces traffic vibration into the manhole structure which great extends the life of the structure and surrounding pavement.

• When installed properly, the Infra-riser reduces water infiltration into the structure.

• Meets LEED requirements for recycled materials. All Infra-riser adjustment risers are made from 92% recycled materials.

• Infra-riser is a lightweight alternative to concrete risers and/or brick and mortar which reduces installation time and injuries.
