Rehabilitating Soils to Increase the Bearing Capacity Under Milk Storage and Grain Handling Facilities

By Robert Armstead

Silos are storage systems designed to contain massive amounts of weight within a concentrated area and vary in size, ranging from 20-80 feet tall with diameters of 12-30 feet. Some storage facilities have more than one or two silos sitting in a small area.  When the silos are full, the significant weight can impact settlement of the foundation and/or the foundations of nearby structures.

In addition to the consolidated weight of tanks that hold liquid and grain storage bins, the surrounding processing facilities get a lot of traffic as well. There is a constant stream of trucks, mostly loaded with heavy cargo, coming and going from the facility. When there is a rail spur next to the facility, the soils underneath and around the grain bins, silos, and mission critical buildings are taxed with even more weight.  Consequently, there is a lot of weight consolidated into a relatively small area around these crucial, very busy facilities.

After heavy rainfall like…

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.

Zero Excavation Inflow & Infiltration Restoration At the Naval Air Station in Pensacola after a High Water Event

By Robert Armstead

Ever since the U.S. purchased Florida from Spain in 1821, the site where the Naval Air Station (NAS) in Pensacola currently stands has provided a base for military operations.   In 1826, construction began on the Pensacola Navy Yard and it eventually became one of the “best-equipped naval stations” in the U.S.  During this period, the Navy Yard was used for docking and repairing the warships of that period. When the Navy saw the advantages of aviation in combat, Pensacola became an aviation training station in 1914 and the station was built on the side of the old Navy Yard.  In 2014, NAS Whiting Field celebrated 71 years in operation and is considered to be the “backbone of the Navy’s flight program” and is still one of the most important Navy bases in the U.S.

Foundation Damage Caused By Melting Snow and Ice

By Robert Armstead

The winter of 2015 will go down in the history books as one of the snowiest. In fact, as of March 15, 2015, Boston had accumulated a total of 108.6 inches of snow.  This was the most amount of snowfall since the city started tracking weather back in 1872.  It has also been a brutally cold winter across the entire Northeast.  Once again, Boston broke records, averaging only 16.1 degrees in February.

After a long season of shoveling, snow blowing and digging out the car in order to go anywhere, warmer weather is a welcome signal that spring is almost here.  Experts predict that this spring’s runoff from melting snow and ice will be the worst we’ve had in the last 15 years. Unfortunately, melting snow and ice can cause damage to houses and other buildings and may uncover some unwelcome cracks in the foundation.  As a…

Sinkholes and Denied Claims

By Robert Armstead

It’s distressing for homeowners to discover cracks in the walkways, pool deck, and driveway at their house.  The cracks become more worrisome when they grow into a trip hazard.  It’s a bigger headache when whatever is causing the cracks in the pavements manifests itself inside the house and, suddenly, cracks appear at seams in the walls, tiles start popping off the floor and doors and windows do not open and close properly.

So what should you do if your home starts experiencing these problems?  Your course of action will depend on what’s causing the cracks.  If you believe the cracks are caused by a forming sinkhole, it’s only going to get worse and could become quite serious – very fast.

Here’s a short segment from an episode of Earth Unplugged explaining what causes a sinkhole and…
