Dealing with Soil Subsidence can be Quick and Non Disruptive

Dealing with Soil Subsidence can be Quick and Non Disruptive

On November 18th, the Tampa Bay Times published a story entitled Is one of Tampa Bay’s premier condo towers sinking?.  The article discusses how “very loose and very soft bay bottom soils” have caused movement of the foundation that has resulted in “significant subsidence concerns and structural design deficiencies.”

Soil Subsidence is a common problem in Florida.  Florida’s sandy soils and geological conditions can cause the soils to collapse away from the surface often times leaving voids underneath foundations and surface structures.  Under instances where there is overbearing weight, the support soils will become inadequate to support the structure. 

First of all, it is always best to ensure that the soil compaction density is sufficient before building the…

In April 2014, Florida’s panhandle experienced a historic flooding event, which was highlighted by 20 in. of rainfall in just two days. For perspective, on average, the rainfall in this area is just more than 60 in. a year.

This once-a-century event caused numerous sinkholes, portions of Interstate-10 were closed and the soils of the entire region were completely saturated for an extended period of time. As the rain waters eventually receded, a large amount of voids were created in the soil, wreaking havoc on the affected areas public works and infrastructure systems.

Specifically, as a result of this storm, the Jackson Lakes box culvert in Pensacola suffered a tremendous amount…

Soil Stabilization under 100-Year-Old FDNY Firehouse

By Robert Armstead

Fire stations are critical in serving the diverse needs of the community where they are located, as well as the fire department they report to.  The New York City Fire Department (FDNY) protects more than 8,000,000 New York City residents living and working in a 320 square mile radius.  The FDNY is the largest fire department in the United States.

The FDNY serves the five boroughs of New York City and includes 255 fire stations.  Each fire station’s differences relate to the size of the firefighting apparatus housed within it and the facility’s location, which is largely driven by the need to minimize response time.  The FDNY Engine Companies are tasked with securing a water supply and extinguishing the fire while the FDNY Ladder Companies conduct search and rescue, forcible entry, and ventilation at the scene of a fire.

Sealing Annular Space in a Sliplined Pipeline

By Robert Armstead

In the United States, billions upon billions of gallons of stormwater are transported through the local sewer systems every day.  The pipes that the water travels through have different degrees of structural integrity.  Some of the pipes are as small as 8 inches in diameter and some are as large as 120 inches.  The storm sewers can be made out of brick, metal, concrete, clay and plastic.  As communities grow and these sewer systems age, local governments are forced to incur costs far beyond the material and labor to rehabilitate or expand the pipelines.  Government officials must also figure out how to alleviate traffic delays, as well as business interruptions and disruption to neighborhoods, which can add to the cost of repairing the stormwater system.

One of the oldest and most cost effective methods of rehabilitating an existing drainage pipe is called sliplining.  With sliplining, a new, smaller “carrier pipe” is installed inside the old, larger “host pipe.” …
