Mouth of Garage Has Become Eye Sore, Nashua, NH

A homeowner in Nashua, New Hampshire, purchased their forever home 2 years ago. The home was built in 2000 and at purchase, they noticed that something was wrong with the apron of the garage. Over the first two winters since purchasing the home, the mouth of the garage has gotten worse. The homeowner would like to have the apron repaired because it is an eyesore. Our design specialist Kenny recommended chipping out the apron of the garage and pouring a new apron. 

Our team first started by chipping out the apron of the garage using jackhammers. The team chipped out 8-12" of concrete so they can replace the apron of the garage. After the concrete is removed the team began mixing concrete. The team made framing so they can make a form for the apron. The team poured and smoothed the concrete inside of the form and then waited for the concrete to cure. Once the concrete is cured the team removed the form. 

The homeowners were happy with how their new garage apron looked.

Cracking Garage Slab, Nashua, NH

A homeowner in Nashua, New Hampshire, had lived in their home for 45 years, and about 10-15 years ago they noticed cracking and shifting in their concrete. The cracking and shifting had gotten worse over the past couple of years and the homeowners are planning on selling the home in the future. The homeowner wanted to repair the cracks in the garage because it had started affecting the mudroom inside their house and could potentially affect a sale in the future. The homeowner planned on moving to Florida sometime shortly. Our design specialist recommended installing PolyLevel and NexusPro to fill the void, lift, level, and seal cracks on the garage slab.

Our PolyLevel Crew repaired the garage by injecting PolyLevel under the slab. The team used our Polyrig to fill the void underneath the slab. Once the void was filled the team performed a lift and level procedure to areas that had sunk. When the team finished the lift and level procedure they then sealed all of the cracks in the garage with NexusPro.

The homeowners were happy with the repair of the garage slab. The concrete was leveled and the cracks were sealed.

Reoccurring Foundation Issues, Nashua, NH

A homeowner in Nashua, New Hampshire, has been living in her home since 1971. Around 2005 she had an issue where some cracks appeared on her foundation walls. She contacted a local contractor that installed Helical Piers. She had them install Helical Piers at the back of her home. Not even 20 years later, the same issue started to happen again. The company that installed the helical piers is no longer in business, so the homeowner had to find a new company to stop her home from sinking and cracking. 

She reached out to EFS. Our design specialist looked at the foundation and recommended using our helical piers to stop the foundation of the home from cracking. 

During installation, our production team found that the old helical had completely failed. Our team installed 8 Helical Piers on the footing of the foundation. 

The homeowner was happy that her home was fully stabilized.

The way the water was flowing off the home and under the home in this way had been going on for years. EFS recommended installing EZ Posts under the mobile home, which would permanently stabilize the structure and prevent it from settling into the wet soil.  The 6 EZ posts installed went down 7' to 8' each, where they hit ledge or extremely compact soils, giving enough support to easily stabilize the weight of the mobile home.

Foundation Wall Bowing, Nashua, NH

Paul G. recently purchased this home in Nashua, NH and had some immediate foundation concerns to address. During the home inspection process, there was a clearly visible, horizontal crack in the foundation wall in the basement. The concrete wall was about 6 and a half feet tall, and bowing in due to pressures from the soils on the exterior. Eventually this foundation wall would completely push in and fail. He planned on living in the home with his family for many years, so Paul needed a permanent solution.

Design specialist Jason Vachon completed a thorough inspection of the bowing wall for Paul, and proposed the installation of PowerBraces as a solution. The PowerBrace system is quick and efficient, requiring no excavation or heavy demolition of concrete in order to install.

Project foreman Nate Erickson and installation specialist Anthony Correa were able to complete installation of the designed PowerBrace system in a single day, and Paul's foundation wall is now permanently stabilized. Overtime, the wall may possibly be straightened as well, though the fix for now was to prevent any further bowing movement and improve the integrity of the concrete wall.
