Crawl Space Waterproofing and Encapsulation in Marengo, OH

After living in their house for 25 years, homeowners in Marengo, OH, had grown tired of dealing with a continuous problem. Water leaked into the crawl space, saturated the walls and floor, and contributed to generally unhealthy and unsightly conditions under the house.

The homeowners were motivated to fix this problem once and for all, so they began to research potential repairs. They found information about Ohio Basement Authority on Home Advisor and were eager to contact us for further guidance. They met with one of our inspectors who evaluated the condition of the crawl space. Our inspector then recommended the perfect repair solutions.

One of our crews waterproofed the crawl space with the SmartPipe drainage system and SmartSump sump pump, and then encapsulated the area in CleanSpace liner.

SmartPipe was placed in the crawl space floor to catch seeping water from the walls and floor. This water is then drained into the SmartSump sump pump, which pumps the water out of the crawl space and away from the home.

Thick and durable CleanSpace was used to completely seal the crawl space and isolate it from the earth. CleanSpace also acts as a moisture and vapor barrier, and it helps insulate the crawl space.

The homeowners can rest easier knowing these trustworthy repairs have helped them create a safer and healthier crawl space and home.

Stabilizing a Cracking Foundation Wall in Marengo, OH

As a traveling nurse, a homeowner in Marengo, OH, doesn’t spend much time at her house. She has owned the home for four years, and she may be staying in the house more often due to recent developments.

While tallying up home improvement projects she wanted to tackle, the owner noticed one of the foundation walls was cracking. She didn’t want this issue to affect her home’s structural integrity or her ability to finish the basement, so she started to research how to address this problem. She contacted Ohio Basement Authority after learning about our company online, and one of our inspectors assessed the problematic wall’s condition. He then recommended one of our reliable foundation repair solutions.

Several Carbon Fiber supports were placed on this wall. These heavy-duty supports permanently reinforce the foundation walls where they are installed, and help prevent any further cracking or bowing. They also can be covered with basement finishing materials.

The homeowner is happy this trustworthy repair was completed to help her create a safer living environment.

Wall Anchors Permanently Stabilize a Failing Foundation Wall in Marengo, OH

A homeowner in Marengo, OH, has lived in her house since it was built six years ago. Even though the house is not very old, one of the foundation walls already is showing signs of failure. This wall was cracking and slightly tilting inward.

These issues greatly concerned the homeowner, who was worried the wall could completely fail and affect the stability of the rest of the home. She began to research potential repair options and companies, and she was eager to contact Ohio Basement Authority for a permanent solution. After meeting with one of our expert inspectors, the homeowner was eager for one of our experienced crews to install one type of our many reliable foundation repair solutions.

We installed several Geo-Lock Wall Anchors on the problematic foundation wall to permanently stabilize it. These heavy-duty, galvanized steel anchors not only reinforce the wall, their unique design also allows them to be tightened for wall improvement. These anchors also offer the best opportunity to straighten the wall.

The homeowner now has peace of mind knowing her home will be a safer living environment because of these trustworthy repairs.

Exterior Drain Lines are Upgraded in Marengo, OH

Homeowners in Marengo, OH, recently began to notice water seeping inside their basement near the corners. Downspout conductor lines happened to be outside these same areas of the basement.

Concerned their basement could sustain more water intrusion and damage, the owners wanted to take the necessary steps to address these issues right away. They contacted Ohio Basement Authority after seeing one of our TV ads, and then met with one of our expert inspectors. The owners were equally eager for one of our experienced crews to update their exterior drainage system.

We did this by installing thick, reliable pipe for the downspout conductor lines. These lines were buried underground and directed to drain far enough away from the home’s foundation and out into the yard. LawnScape outlets were attached to camouflage the ends of these lines.

The homeowners are pleased to have upgraded discharge lines that will help keep their home dry.

Stabilizing Cracking, Failing Foundation Walls in Marengo, OH

While they have lived in their house for 30 years, it wasn’t until recently that homeowners in Marengo, OH, noticed structural issues with one of the foundation walls. This wall was showing signs of failure in the form of various cracks, and it appeared to be slightly slanted.

The owners have no plans to move from the house, so they wanted to make sure it would always be structurally stable. They began to research possible repair options and companies, and they knew they could count on Ohio Basement Authority for a permanent solution after talking with trusted friends and neighbors who also had repair projects completed by our company.

After they met with one of our experienced inspectors, the owners were eager for one of our expert crews to install two types of our many reliable foundation repair products. We installed two Geo-Lock Channel Anchors on the severely cracking and bowing portion of the wall, and several Carbon Fiber supports on the less dangerous side of the wall.

Both of these products permanently stabilize the problematic foundation walls and prevent further cracking and inward bowing. The Channel Anchors, which are bolted to the floor, also offer the best opportunity to straighten the walls.

The homeowners now have peace of mind knowing their forever home will be a safe living environment for many more years to come.

Basement Waterproofing and Egress Window Installation in Marengo, OH

A homeowner in Marengo, OH, contacted us because a corner of the house was leaking water. The basement was finished and included a utilized fourth bedroom. 

One of our certified inspectors visited the home to determine which repairs and products would work best for this particular case.

He and the homeowner decided to go with a new egress window because the old one seemed to be falling out and causing some of the water leakage. They also wanted to include a SuperSump pump system with the UltraSump battery backup. 

The installation crew came in and first installed the egress window. This is a window large enough to use as an escape route in the event of an emergency, and they are required for a finished basement. It also includes steps out to allow easier access to the surface.

Lastly, they installed the SuperSump pump system which is a 1/2-horsepower cast iron pump which can pump up to 2,200 gallons of water per hour. They attached the UltraSump battery backup which will keep the pump working in the event of a power outage.

The homeowner is happy with these waterproofing repairs, and he no longer has to worry about water pooling in his finished basement.

Our basement wall is bowing in and cracking on inside and outside. The house is newer and was not built right the 1st time around so looking to see what we need to do to stop it from moving anymore. Thanks
Vicinity of in Marengo
I'm in contract to purchase this house and it has some basement issues that I'd like to get inspected and quoted. The home inspection revealed about a dozen vertical cracks in the poured basement walls that go from the floor to the ceiling. They are all thin and most would be considered hairline. There is some discoloration on some of them suggesting some water intrusion.

I would like to have an evaluation/estimate done on my crawlspace. It is moist down there nearly year-round and it has a musty, moldy smell. Moisture content in the rest of the house is high as well.
