Product used

StrataGrid™ – SG500 and SG550


Construction of reinforced soil structure

About the project

The owners of the Donzi Lane Landfill wanted an innovative way to expand the existing capacity of the landfill. Since lateral expansion was not possible, Strata recommended vertical expansion with a steepened slope.

However, vertical expansion created an added complication. The existing high-tension lines were mounted on transmission supports that traversed the centre of the landfill. Height limitations were so severe that dump trucks could no longer lift their beds to discharge waste without interfering with power lines.

Strata’s technical team of civil engineers designed an innovative and the most appropriate solution – StrataSlope™ System with geogrid-reinforced steep slopes with wire-basket fascia. This was the safest and highly engineered method of expanding the tightly restricted landfill.

The primary reinforcement layers consisted of StrataGrid™ SG500 and SG550 with maximum embedment lengths of 26 feet. Vertical spacing of the primary reinforcement varied. The vertical spacing for the initial 6 feet of slope construction was 1.5 feet, while 3 feet vertical spacing was utilized for the remainder of the slope up to the maximum vertical height of 40 feet. The facing detail utilized StrataGrid™ SG150 for secondary reinforcement and 90-degree welded wire baskets for facing support.

Strata’s value addition:

  • Rapid and safe construction with sound systems
  • Cost-effective by providing more storage revenue within the same land space
  • Increased the total dumping capacity by 3 million cubic yards (~ 2.29 million cubic meters)
