Gravity Retaining Walls

PROJECT FACTS:  Wall Repair Area = 5,300 SF; Max Ht = 17 FT

CHALLENGE:  A poorly constructed cast-in-place concrete retaining wall supporting the slope next to this self storage facility failed catastrophically.  The failure also put an adjacent high pressure gas line at risk.

SOLUTION:  Pinnacle Design/Build designed a gravity retaining wall using Redi-Rock ^TM large block units to replace the failed wall.  Our crews carefully demolished and removed the failed structure and replaced it without incident.

VALUE:  The Pinnacle Design/Build solution saved the developer over $500,000 when compared to other potential solutions. In addition, the entire project (design to closeout) was completed in 28 days without damaging ore even taken the gas line of of service.

PROJECT FACTS:  Wall Area = 1,280 SF; Max Ht = 8 FT

CHALLENGE:  A segmental retaining wall supporting the parking lot of a K-mart store had experienced failure.  The owner wanted the wall repaired without impacting store operations.

SOLUTION:  Pinnacle Design/Build designed a gravity retaining wall using Redi-Rock™ large block units to replace a portion of the failed wall.  Our crews carefully demolished and removed the failed structure, regraded the area and constructed the gravity replacement wall.

VALUE:  The Pinnacle Design/Build solution was implemented without complete demolition of the existing wall which would have impacted store operations.  The partial reconstructions saved significant time and money when compared to other options.

PROJECT FACTS:  Wall Area = 1,000 SF; Max Ht =  15 FT

CHALLENGE:  A century old, stacked stone retaining wall supporting Palisades Drive where it passes over a  protected, environmentally sensitive creek was progressively failing.  The failing wall put the busy roadway above and its passengers at risk.  The wall had to be repaired without compromising the creek and with minimum impact to traffic.

SOLUTION:  Pinnacle Design/Build designed a gravity buttress wall using Redi-Rock™ large block units to stabilize the failing wall.  Our crews carefully constructed the challenging repair without incident.

VALUE:  The Pinnacle Design/Build solution saved the town over $300,000 when compared to other solutions considered.  In addition, the entire project (design to closeout) was completed in less than one month while keeping the Palisades Drive open to traffic.

PROJECT FACTS:  Wall Area = 3,000 SF; Max Ht =  6 FT

CHALLENGE:  An existing retaining wall and slope supporting the bleachers are this high school football stadium were in disrepair and required rehabilitation.  The school had a limited budget for the work.

SOLUTION:  Pinnacle Design/Build engineered and constructed a gravity retaining wall with an architectural finish at the toe of the deteriorated wall/slope. 

VALUE:  The engineered solution provided the required structural stability and a pleasing aesthetic appeal.  The gravity wall system also cost less than the structural concrete alternative.

PROJECT FACTS:  Wall Area = 1,000 SF; Max Ht = 6 FT

CHALLENGE:  This restaurant was to be built in a area with many existing utilities.  The perimeter of the site required retaining walls to obtain the desired grade.  Conventional wall systems would have required excavation/relocation of the existing utilities. 

SOLUTION:  Pinnacle Design/Build engineered and constructed a large block gravity retaining wall system that could be constructed without disturbing the existing utilities.

VALUE:  This system limited the amount of excavation and the necessity to pay for expensive relocation of existing utilities.
