TripleSafe Sump Pump in Bethlehem, New Hampshire

When the old sump pump in the basement couldn't handle the amount of water entering the basement the homeowner contacted Matt Clark's Northern Basement Systems, to set up a free estimate.  After meeting with a system design specialist they decided the best way to keep the basement dry was to replace the old pump with a TripleSafe Sump Pump.  The TripleSafe has three separate motors.  The first pump is a heavy-duty 1/3 horsepower (HP) cast-iron Zoeller pump that does most of the pumping, handling up to 2,600 gallons of water per hour.  The second pump is a 1/2 HP pump that operates automatically if Pump 1 fails or if greater pumping volume is needed (up to 6,200 gallons per hour).  The third pump is a battery-operated pump that turns on automatically if power fails.

With bowing walls in their basement, a homeowner in Bethlehem, New Hampshire hired Matt Clark's Northern Basement Systems to permanently stabilize the walls.  Matt's team of experts installed a Geo-Lock Wall Anchor System.  This will permanently stabilize the basement walls, offering the best opportunity to straighten the walls without the cost and disruption of foundation replacement. Heavy duty, galvanized earth anchors are embedded in stable, undisturbed soil outside your foundation wall. Each anchor is connected by a steel rod to a wall plate that provides clamping pressure against the inside of the foundation wall. Overtime this method also offers the potential to straighten the wall back to its original position.
