Job Stories From Peterborough, NH
Basement Waterproofing in Peterborough, New Hampshire

A homeowner in Peterborough, New Hampshire, had recently purchased a new home.  During the home inspection, there were areas of concern brought to the attention of the future homeowner.  The home inspector pointed out that there were visible signs of previous water seeping into the basement and also showed a wall that needed to be evaluated by a structural engineer. 

The homeowner set up an appointment with a structural engineer. After a thorough inspection, it was determined a form of structural support was in need to maintain the integrity of the foundation.  The structural engineer referred the home buyer to Matt Clark's Northern Basement Systems, a company that he used all the time for his clients, always did outstanding work, and who could perform the tasks of both waterproofing and structurally repairing the foundation. 

After a free estimate form one of Northern Basement Systems System Design Technicians, a plan was carried out to both waterproof and structurally repair the new homeowner's foundation.   

Matt Clark's Northern Basement Systems installed a Clean Space Wall System and tied it into a newly installed Perimeter Water Guard Drainage System.  These two systems will take any water seepage and direct it to the sump pump for discharge.  The new Super Sump Plus Sump Pump will pump out any water down a discharge line, then out of an Ice Gaurd Discharge System.  

To secure and maintain the foundation wall the engineer deemed unsafe, Matt's team installed Galvanized Steel Power Braces.  The Power Braces will permanently support the once failing wall.  

The basement is now structurally sound and waterproofed, ready for the new homeowner to relax and enjoy.

Wasn't able to pull the trigger in 2015, but I'm desperate for extra storage space now, and really need to be able to utilize the space. Without a pump running, the basement can get a foot or more of water in the Spring.
