Your Experienced Contoocook, NH Concrete Repair & Radon Mitigation Company

A homeowner in Hopkinton, New Hampshire had been living in their house for approximately a year. When they purchased the house, the seller assured them that the basement was not prone to flooding. However, after a year of living in the house, they faced basement flooding and discovered signs of mold and mildew. The homeowner had plans to finish the basement in the future but couldn't do so due to the flooding and mold growth. They contacted EFS for a free inspection of their basement. Our Design Specialist, Isaac Hernandez, met with the homeowners, assessed the situation, and proposed a solution. Isaac suggested installing a full perimeter drainage system that included 100' of WaterGuard, a TripleSafe sump pump, 2 IceGuards, a SaniDry Sedona dehumidifier, and a buried exterior drainage line to prevent water from entering the basement and eliminate mold and mildew.

Our Installation Team began by chipping the perimeter of the basement to install the perimeter drainage system and sump pump. They used a jackhammer to break up the concrete into manageable pieces that they could remove from the basement. Once they removed all the debris, our team installed the drainage system and sump pump. Next, the team plumbed the sump pump to the exterior of the house, where they installed two IceGuards and a 10' buried exterior drainage line. After the exterior drainage was installed, the team returned to the basement to pour concrete around the basin of the sump pump and cover the perimeter drainage to lock them into place. Finally, the team placed the SaniDry Sedona dehumidifier next to the sump pump to control humidity levels in the basement and prevent mold growth.

The homeowner was thrilled with the work that Erickson had done in their home. They no longer have to worry about water or mold issues in their basement.

A homeowner in Contoocook, New Hampshire, built their home in 2019, and shortly after moving in they noticed a section of concrete in the garage had begun to sink. Over the next few years, they have seen the concrete sink further and further down. The homeowners noticed their doors starting to get tight so they called EFS for a free inspection of their home. Our Design Specialist Isaac examined the slabs in the garage. He used a laser level to determine how much the slabs had sunk. He found that the back right slab in the garage had sunk 2" and the front right had sunk about 1". Isaac recommended installing PolyLevel into the garage to lift and level the slab. Isaac also recommended installing NexusPro to seal the control joints. 

Our installation team began by drilling portholes in a grid pattern around the garage so we could lift and level the slab without cracking it. After the holes were drilled the team then started to inject PolyLevel beneath the slab. The team first filled the void in the areas of the slab that have sunk but then lifted the sections that had sunk. Once the slab was lifted and leveled they then cleaned up any excess poly that had seeped through the cracks. After the poly was cleaned up, the team then used some universal concrete to plug the injection portholes.

The homeowners were very impressed to see our team and PolyLevel in action. They watched their concrete get lifted back to level in a matter of minutes and it was cleared to drive on by the time the team left. 

A homeowner in Contoocook, New Hampshire, had lived in their home for the past 10 years. They planned to remodel their garage but needed to make sure the slab can be fixed. The homeowners were told by other contractors that they would need to pour a brand new slab. The homeowners then reached out to EFS to see if we could find them a repair. Our design specialist Victor recommended installing PolyLevel and NexusPro to lift, level, and seal the slab in the garage. 

Our production team first started by drilling port holes in a grid pattern into the slab. The port holes gave the team a space to inject PolyLevel under the concrete. The team injected the PolyLevel under the slab to precisely lift and level the concrete. After they lifted and leveled the slab the team then started sealing the cracks with NexusPro. They used a motorized caulking gun to squeeze NexusPro into all of the cracks. To make sure the cracks are sealed the team used a set of metal spoons to push the NexusPro deep into the cracks and to leave a smooth finish. 

The homeowner was very happy with the results of the project. They can finally remodel their garage like they wanted to.
