Retaining Wall Repair

PROJECT FACTS:  Wall Repair Area = 14,600 SF; Max Ht = 29 FT

PROJECT FACTS:  Wall Repair Area = 2,800 SF; Max Ht = 20 FT
 

CHALLENGE:  A large diameter headwall supporting the velodrome bicycle track failed from foundation scour.

SOLUTION:  Pinnacle Design/Build designed an MSE retaining wall with a welded wire form (WWF) stone facing to replace the failed headwall. Our crews carefully demolished and removed the failed structure and replaced it without incident.

VALUE:  The Pinnacle Design/Build solution saved the owner $100,000 when compared to other potential solutions.

PROJECT FACTS:  Wall Area = 2,300 SF; Max Ht = 17 FT
 

CHALLENGE:  The retaining wall supporting the parking lot and drive thru lane of this restaurant failed due to scour at the toe.

SOLUTION:  Pinnacle Design/Build designed a scour mattress and an MSE buttress wall with a welded wire form (WWF) stone facing to shore the failed block wall.  Our crews constructed this mattress and wall system in front of the failed structure and without incident.

VALUE:  The Pinnacle Design/Build solution was quickly constructed providing the required structural support with minimal disturbance to the restaurant operations.  Compared to other options considered, this approach saved substantial time and money.
 

PROJECT FACTS:  Wall Repair Area = 2,900 SF; Max Ht = 18 FT
 

CHALLENGE:  The segmental retaining wall supporting the parking lot and drive thru lane of this pharmacy was settling and unstable.  The pavement and fencing above the wall was damaged and could not be repaired until the wall was stabilized.

SOLUTION:  Pinnacle Design/Build designed an MSE buttress wall with a welded wire form (WWF) vegetated facing to shore the failed block wall.  Our crews constructed this wall system in front of the failed structure and without disrupting store operations or disturbing the surrounding properties.

VALUE:  The Pinnacle Design/Build solution effectively stabilized the wall at less than half the cost of other options considered.
 

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 = 1,000 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 Repair 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 ^TM large block units to replace a portion of the failed retaining 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 reconstruction saved significant time and money when compared to other options.

PROJECT FACTS:  Wall Area = 4,000 SF; Max Ht = 22 FT

CHALLENGE:  An existing MSE segmental retaining wall (SRW) supporting this multi-family housing development was bulging and in danger of collapse.

SOLUTION:  An engineered system consisting of soil nails through the existing wall (to stabilize the mass) and a matching SRW facing was constructed.

VALUE:  This composite retaining wall solution of provided a quick and visually pleasing repair that did not require total demolition of the failing wall or major disruption to the residence of the community.
