Your Proven Hollis, NH Concrete Repair & Foundation Repair Company

Recently, a homeowner in Hollis, NH, reached out to us with a problem that's all too familiar - a damp, musty crawl space causing cold floors and worries about long-term structural damage. Understandably, the thought of moisture wreaking havoc beneath their home was a cause for concern, thankfully, our team at Erickson Foundation Solutions was more than ready to tackle the challenge.

Following our step-by-step process, we sent System Design Specialist Chuck Benedict to perform a thorough inspection of the home. It didn't take long to confirm the homeowner's suspicions—the crawl space was indeed trapping excess moisture, posing a risk to both the home's foundation and overall indoor comfort. Our expert drafted up a tailored solution to address the root of the problem effectively. Our course of action included the installation of several key products: SilverGlo insulation to keep the cold out and maintain a stable temperature, a CleanSpace liner for sealing off moisture, and the SaniDry Sedona dehumidifier to eliminate any remaining dampness and further control the climate in the crawl space. These installations, along with the careful placement of a drainage matt, TerraBlock, and an updated EverLast Crawl Space Door, ensured the encapsulation of the area for ultimate protection against moisture.

As the project wrapped up, the difference was clear. The homeowner's floors above the crawl space were noticeably warmer, and the worry of moisture-induced damage was replaced with peace of mind, knowing their crawl space was now a clean, dry, and energy-efficient area beneath their home. This transformation proved once again that with the right expertise and solutions, issues like these are entirely manageable. Furthermore, this homeowner can rest easy, reassured by the durability and effectiveness of the improvements made to protect their crawl space.

When homeowners in Hollis, NH noticed the floor above their garage starting to show major cracking, they realized they were dealing with more than just cosmetic issues. Concerns about the integrity of their home's structure led them to reach out to us at Erickson Foundation Solutions.

Recognizing the seriousness of their situation, we quickly scheduled a home inspection to assess the problem firsthand. Upon inspection, our System Design Specialist Victor Tapia discovered that inadequate support was the root cause of the cracking. To tackle this issue effectively, we recommended installing SmartJack - a high-strength, adjustable steel pier designed to provide stable support and correct sagging floor problems. With a clear solution in mind, our production team got to work. The installation of SmartJack in the garage was executed with precision and care. The process involved preparing the base, placing the SmartJack system, and adjusting it to the ideal height to ensure the floor was perfectly level and supported.

The outcome was immediate. The once-cracking floor was stabilized, laying any fears of ongoing structural damage to rest. Moreover, the solution not only halted further deterioration but also reinforced the area to prevent similar issues in the future. The Hollis homeowners could now rest assured, feeling safe in the knowledge that their home was supported by a reliable, long-lasting solution. Through our expertise and dedication, we were able to transform a homeowner's concern into peace of mind, staying true to our mission of delivering a remarkable customer experience from the initial inspection to the final solution.

Recently, we at Erickson Foundation Solutions had the opportunity to transform a crawl space in Hollis, NH, that was becoming more of a headache for the homeowner than a functional part of their house. They were dealing with a rather unpleasant situation where water leakage into their crawl space was leading to wood rot and mold, a clear threat to both the structure of their home and their health. Understandably worried, the homeowner reached out to us looking for a durable solution.

Following our established process, our Customer Care Team promptly scheduled a home inspection to assess the severity of the problem. Our expert System Design Specialist, Bryan Barnard, visited the residence to perform a comprehensive evaluation of the crawl space. It didn't take long to verify the extent of the water intrusion and its damage. Based on these findings, we recommended the installation of our CleanSpace product, a reliable and efficient remedy for their crawl space woes. CleanSpace is not just any covering; it's a heavy, durable plastic liner that envelops the entire crawl space, effectively isolating the home from the earth. This creates a barrier that moisture cannot penetrate, preventing future cases of wood rot and mold growth. Our skilled production team carried out the CleanSpace installation with precision, ensuring every inch of the space was covered and sealed properly. They made sure to cause minimum disruption while working and cleaned up after completing the installation, leaving the home safer and the homeowner relieved.

The transformation was remarkable. No more water trapped in the crawl space meant no more worrying about structural damage or health risks from mold. The homeowner was not only relieved but thrilled with their newly secured and dry crawl space, all thanks to a sustainable solution provided by our team.

A new homeowner in Hollis, New Hampshire, recently noticed that the wooden supports in the basement of their block foundation home were old and rotting. They contacted EFS for a free inspection, and our Design Specialist, Isaac Hernandez, examined the supports. Isaac found that the wooden supports had deteriorated due to exposure to water and recommended that they be replaced with our galvanized steel SmartJacks. Although Isaac also recommended a waterproofing system, the homeowners opted to wait on that.

Our installation team, led by Neal Foley, began by setting up temporary posts between the wood supports to provide support for the floor system while the old supports were removed. Once the old supports were removed, we chipped out concrete to install our big plate footings beneath the concrete slab. After the three footings were installed, we put in the supports and connected the adjustable top to the beam using screws. The SmartJacks were installed, and we finished by mixing concrete and covering the big footings to lock the supports in place.

After cleaning up the job site, we did a walkthrough with the homeowners and showed them the SmartJacks and some of their features, including the adjustable top that can lift the floor to make it level. The homeowners were very pleased with the installation of the system.

A homeowner in Hollis, New Hampshire had been experiencing water intrusion in their basement since they moved in back in 2017. Despite their construction background, their DIY attempts to solve the issue had been unsuccessful. The homeowner was tired of having to vacuum the water out of the basement and wanted to finish it once the water issue was resolved. As a result, they contacted EFS for a free inspection. Our Design Specialist, John Prince, inspected the basement and determined the source of the water intrusion. He recommended installing a full perimeter drainage system with radon-neutral perimeter drainage to prevent radon seepage.

Our installation team, led by Anthony LoCascio, began by removing over 100 feet of concrete around the perimeter of the basement. This allowed us to install the perimeter drainage and TripleSafe sump pump. We installed the sump pump basin to eject water out of the basement while we worked. We then installed the Radon Neutral WaterGuard and Trench Lock around the perimeter of the basement and added 58 feet of CleanSpace wall to protect that section from water seepage. The team finished by installing the exterior drainage system to carry the water away from the foundation of the home. They also installed 10 feet of buried exterior drainage and attached it to IceGuard to prevent exterior drainage backup into the basement. Lastly, the team covered the perimeter drainage with concrete to lock the system in place.

The homeowner was extremely pleased with the installation of the new system. Since installation, the homeowner has not seen any water in the basement. They can now begin the process of finishing the basement.

A homeowner in Hollis, New Hampshire bought their parent's home 10 years ago. The house was built in 1963, and the foundation wall of the garage had bowed, causing concern for the homeowner. They spoke to another company that suggested pouring a new wall, but the homeowner was not interested in that solution. Instead, they contacted EFS for a free inspection of the garage foundation. Our Design Specialist met with the homeowner, and after inspecting the entire garage structure, recommended replacing the existing foundation wall with a Masonry Block Wall Foundation. The homeowner chose our company due to our experience in the industry and our superior solution.

Our Installation Team, led by Nick Carelli, began by setting up temporary supports and removing the existing foundation wall. After the wall was removed, the team poured a new footing and let the concrete cure. Once the curing process was complete, we began to lay the blocks for the new foundation wall. When the team reached the framing of the garage, they put on the finishing touches and installed waterproofing on the outside of the wall to prevent water from seeping through the foundation. After the waterproofing was installed, we started to backfill and tamp the soil back to its original position.

The homeowners were delighted with the results of the project and how the team left their home better than they found it.

A homeowner in Hollis, New Hampshire, had finished building their home last year. Since they've been living in the home they have seen water entering the basement. The water seems to be coming from their bulkhead and a small crack in the foundation wall. The homeowners decided to call EFS for a free inspection of their basement. Our Design Specialist Kenny examined the entire basement and recommended installing crack injection to seal the crack on the foundation wall and installing TrenchLock to the door at the bottom of the bulkhead to collect any water that enters. 

Our Installation Team began by injecting 4' of Crack Injection into the crack on the foundation wall. After the crack was sealed, the team installed a Crack Monitor to keep track if the crack continues to move or not. Next, the team then installed a 5' section of TrenchLock to the bottom of the bulkhead entrance. 

The homeowner was very happy with the results of the project. Since the project, they haven't seen any water enter the basement of their new home. 

A homeowner in Hollis, New Hampshire, has lived in the home for the past 18 years. They recently tested their home for radon and the results came back around 7 pCi/L. The homeowner wanted to find a reputable company to install a radon mitigation system in their home. They reached out to EFS and our Design Specialist designed a radon system that would be in their home. Because of the size of the home the Design Specialist recommended installing a second extraction point. 

Our Installation Team began by creating the two extraction points on opposite sides of the basement. The team used a core drill to make a circular hole in the slab so the team could fit a PVC pipe to each extraction point. The team then connected the two extraction points with PVC and fed them to the exterior of the home where we installed a fan to the side of the home. We then connected the PVC pipe and the fan and then vented the entire system above the roofline of the home. 

After the system was fully installed, the team then tested the home again for radon. The results of the test were well under our goal of 4.0 pCi/L. The homeowner was very pleased with the results of the installation of the radon system. 

A homeowner in Hollis, New Hampshire, had lived in their home for the past two years. When they moved in they noticed the cracks in the garage slab. Since then the problem has only gotten worse. They want to have the concrete leveled and the cracks sealed. The homeowners decided to call EFS for a free inspection. Our Design Specialist James inspected the home and recommended using PolyLevel to level the concrete and seal the cracks with NexusPro.

Our installation team began by having everything removed from the garage. Then the team will drill small holes in the concrete so we can inject PolyLevel underneath the garage slab. The team drills the 1/4" holes in a grid pattern around the garage so we could lift the garage in sections. Once all of the port holes were drilled through the slab, the team then started up the PolyLevel rig and began injecting PolyLevel foam into each of the port holes. The team injected PolyLevel into each hole until the PolyLevel Technician felt the concrete start moving upward. They used a level to check that the entire slab was level. After the team finished will the PolyLevel, they moved on to seal all of the cracks in the garage using 100' of NexusPro. Once the team sealed all of the cracks and ports were sealed the team then did a walkthrough with the customer to show them the work. 

The homeowners were very pleased with the results of the project. 

A homeowner in Hollis, New Hampshire was beginning the process of installing an inground pool in their backyard. During the backyard excavation, they removed a set of stairs against the foundation wall. Behind that set of stairs brought up potential concerns about the foundation wall. To ensure the foundation wall was secured, they called EFS for a free inspection. Our Design Specialist Victor inspected the foundation of the home to reveal nothing of major concern, but when the homeowners were in the basement with Victor they mentioned they noticed a musty smell in the basement and they felt that the first floors have a bounce to them. Victor furthermore inspected the basement and found that the supports in the basement were a mix of old wooden and temporary supports. Victor recommended installing 12 SmartJacks to replace the old supports and a SaniDry dehumidifier to eliminate the musty smell in the basement. 

Our production team began by installing a SaniDry into the basement of the home to control the humidity in the basement. After the dehumidifier was set up the team began setting up our temporary posts around the basement so we could remove the old supports. The team, abiding by the drawing done by Victor, marked where each of the 12 SmartJacks will be installed. To install the SmartJacks, the team first had to excavate some dirt from the dirt floor so they can create a strong footing for each SmartJacks. After they removed some dirt the team mixed and poured concrete into each of the holes they made. Once the concrete had been set, the team then placed the SmartJack footings over each concrete footing. The team made sure that each of the footings that we installed would have to be level before installing the rest of the SmartJack. After all of the footings were installed and leveled, the team then installed the support and the adjustable bracket to the main beam of the home. Once all of the supports and brackets were installed they used the adjustable bracket to make sure the floors were leveled above. 

The homeowner was very pleased with the results of the project. 

A homeowner in Hollis, New Hampshire, had water entering their basement and causing damage to the floors and belongings. Water appears in the basement during periods of thaw/ melt, and or heavy rains. The homeowner has seen up to 4" of water in their basement at one time. Our design specialist Tom recommended installing a perimeter drainage system in their basement. 

Our waterproofing team began by chipping out concrete at the base of the basement wall. The team chipped out a 6" wide trench around the entire perimeter of the basement. This trench will hold our WaterGuard perimeter drainage system. Any water from the wall or the ground will be collected by this channel and directed to a sump pump. As the team was chipping out the concrete for the WaterGuard the team also chipped out the basin for the sump pump. After the team was finished chipping all of the concrete they began laying the WaterGuard into the channel. The team connected each section of WaterGuard with a strong adhesive and made sure to pitch the WaterGuard so the water can run downhill toward the sump pump. The team installed the TripleSafe Sump and connected it to the WaterGuard. Once the WaterGuard and TripleSafe are connected the team began mixing concrete to cover the perimeter drainage and around the sump pump. When the concrete was curing the team used a coring drill to make a hole in the wall to allow the drainage pipe to push water outside. Attached to the drainage pipe on the exterior of the home, the team installed an IceGuard to prevent water from backing up into the basement. The team dug a trench for the drainage line. The trench was dug out into the yard to prevent water from re-entering the home.

The team completed installing the perimeter drainage system in the basement. The homeowner doesn't have to worry about water collecting in their basement anymore.

Wendy R. of Hollis, NH had concerns with high radon levels in the home she had recently purchased. After testing, levels were at 5.6 pCi/l in the basement. She chose Erickson Foundation Supportworks as her contractor to install a radon mitigation system in order to lower these levels. 

When crew foreman, Nick Carelli, began installation of the system in the basement, he had to drill a 5" hole through the concrete slab. Upon breaking through the slab, he found the water table was very high under the home. He suggested to the new homeowners that if they wanted to fully protect their investment, they should consider installing a water sump pump system. Rather than wait for the water to rise and have a concern with cleanup and possible damage, Wendy decided to be proactive and have the sump pump system in place in order to protect her home.
