Retaining Wall Repair, Derry, NH

Retaining Wall Repair, Derry, NH

Retaining Wall Repair, Derry, NH Retaining Wall Repair, Derry, NH

A retaining wall that was previously removed 25 years ago and had been placed next to the house foundation caused some damage to the house foundation. The retaining wall that was removed was tipping from water damage, no drains had been installed, a not enough rebarb was used when it was installed. The new retaining wall is in very good shape and has had no issues. Over the years the concrete that was used to fix the damage has shrunk leaving a large space between the house foundation and the retaining wall. Erickson Foundation Supportworks sealed the crack with polyurethane foam and a new top leayer of concrete to smooth it out.

This older foundation on a home in Derry, NH was part stone and part concrete. The stone parts were crumbling and allowing for soil to be pouring into the basement area. The overall stability of the wall was poor, and so Erickson installed an auxillary wall along with some PowerBraces to fully stabilize the wall and clean up the look of the basement.

Job Stories From Derry, NH
Smart Jacks Installation, Derry, NH

This homeowner in Derry, New Hampshire lives on Beaver Lake and has been experiencing unlevel floors and the corner of their porch is sinking. Design Specialist Royce Potts came to the home and walked through the home and the basement to better understand what conditions the house was in. He suggested that they install SmartJacks in the crawlspace of the home to add support and lift it some. 

Crew Lead Scott Crandall and his team came to the home and installed the SmartJacks into the crawlspace. Using the SmartJacks gave the home some interior support and some lift. The homeowners were very happy with the results of the project.

EZ Posts Under Existing Structures

This customer was having a sunroom installed on top of their existing deck. The deck was not built for supporting a structure above, and so additional supports were needed below. There was only about 3.5 feet of space beneath the deck, and so getting underneath to dig and pour new concrete piers would not be an easy task.

EZ Posts were an ideal solution, as the existing deck floor was going to be completely covered by the sunroom. This allowed our Erickson Foundation Supportworks crew to cut small holes into the surface of the deck. Through these holes we were able to install EZ posts with our Bobcat using pier extensions.

A project which would have taken 2-3 crew members one or more days to complete was finished within 4 hours. The EZ Posts were installed at depths ranging from 7 to 9 feet. We removed some concrete pillars in order to install two of our EZ Posts, these concrete pillars being only two feet deep. It was a good decision to replace them!

Settling Foundation

This homeowner in Derry, NH contacted us as she noticed a large crack in her garage wall near a corner. Upon inspection, our design specialist observed there were few signs of settling within the house aside from windows being slightly stuck. However, on the outside of the garage there were significant signs of sinking which would then lead to extensive damage within the home. 

The solution; push piers to raise the sinking corner 3-4 inches and prevent the foundation from sinking any further. 

We excavated the outside of the garage down to the footing of the foundation. We found the general contractor who built the home placed the footings and foundation directly on stumps and trees, which of course is a big mistake. As the trees decomposed, the ground began to sink and took the foundation with it. 

Our push piers were securely fastened to the bottom of the footings on the foundation and driven down 10-12 feet, beneath the sinking soil and into the bedrock below. This will prevent the home from sinking any further. We also slightly lifted the footing up to the bottom of the foundation to reconnect them, however chose to not lift the house too much as there was little damage within the house. Lifting the house too much could possibly have cracked the drywall.

Problem solved and customer satisfied.
