PRODUCT USED

StrataWall™ and StrataGrid™

APPLICATION

Construction of a temporary mechanically stabilized earth wall

About the project

The project included more than 11 miles of tunnelling that encompasses work in multiple locations in Manhattan, Queens and the Bronx. It provides travel to over 162,000 passengers per day. Since most of the project was in urban areas, delivering the construction materials was challenging due to severe space constraints and the job scope. For the smooth flow of construction, a temporary retaining wall was suggested.

Strata’s geotechnical experts suggested an innovative approach to this – StrataWall™. This solution incorporated a hot-dip galvanized 4×4 wire form facing elements with geotextile and geogrid facing wrap. The StrataWall™ system and design met project requirements and provided the needed 10-year design life. It was constructed to fill a 70-foot (~21 m) hole that abutted vertical walls on either side. Materials had to be delivered with a crane into the hole where the MSE wall was constructed. Since StrataGrid™ is rolled and easy to handle, it made material transport and delivery much more efficient.

Strata’s innovative solution resulted in an economical, fast, and smooth construction of the mechanically stabilized earth wall.

StrataWeb® geocells – A slope erosion protection system for embankments

The Jordan Ministry of Energy and Mineral Resources (MEMR) was planning to build a petroleum strategic reserves terminal in the east of Amman, Jordan. They wanted to increase the petroleum storage capacity in the area, which required an increase in the base width of the embankment. The slopes of the embankment required protection from slope erosion.

Slope protection of partial wall on flyover using StrataWeb® geocells

The ramps of the grade separators are constructed either as embankments with natural slopes or as reinforced soil walls. In the case of partial walls, where sloped embankments are supported on reinforced soil walls, the embankment slopes needed to be given adequate protection against soil erosion, which could otherwise damage the fascia of the underlying reinforced soil wall and also induce seepage into the system. The slopes of the embankments were of the order of 30° with the horizontal. The reinforced soil walls supporting the embankments were as high as 10 m. The heights of the embankments were of the order of 5 m.

Rehabilitation of road in the busy city town centre in Karnataka

Monsoons in North Karnataka are notorious for damage to roads. The site was plagued with problems like reflective cracks, potholes, undulating surfaces etc., resulting in slow traffic movement and heavy vehicular damage. This stretch had to be rehabilitated time and again over the past several years, and no solution was proving to be long-term. Since the area is a major commercial hub, it was impossible to close off this section for an extended period completely, so a quick but long-term solution was needed.
