"I was concerned about moisture in my basement and decided to utilized Managed Service Group for a second opinion. Scott, the contractor, was upfront, honest, and told me what the problem was. He did not come out with 10 plus men to rip out my basement like JES Foundation Company wanted to do. Thank you Scott for saving me thousands of dollars. I will definitely use and recommend this company to others."

"Insulating a crawl space is incredibly expensive (especially for a space that hardly anybody ever sees or goes into), but they did a good job and it has helped in keeping the pipes warmer in winter and reducing damp feeling inside the house."

"Nearly three years ago, I asked JES to install a waterproofing system around my basement (in 2016). After they did this, there was no further flooding or leaking of ground water into my basement. In addition, the dehumidifier makes the whole house smell fresh."

"All of the folks that I dealt with were very knowledgable and professional.  Ms. Elmore and Joanne (Office Manager) were very helpful throughout the process.  All this happened just before Christmas and they were not sure if all the required permits, etc.could be obtained before the holiday due to early closing by local government on 12/23/13.  Received a cll on 12/26/13 that the crew would be at my home on 12/27/13.  I informed my kids who were visiting that this would be happening, and to answer any questions that may arise since I would be at work. 
The crew members arrived on time as specified and started immediately prepping the work area and then beagn the work.  My  oldest stated to me that the work was accomplished very well and when all was completed, she said that the foreman cme over to the house to inform her that they were done but were waiting on the County Inspector.  The crew while waiting finished up cleaning the area or any waste and when the inspector showed, he passed everything with flying colors.  The foreman came back over and had my oldest turn on the water in the kitchen and dowenstairs toilet to be sure the water flowed smoothly and the pressure was up to where it should be.  She told me that with the exception on a bit of sputtering at first and some discoloration evrything was outstanding.
Will definitely use again.

Basement Waterproofing FAQs, answered by experts

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

The most flood-resistant materials you can count on in a flood scenario are concrete, closed-cell insulation, foam insulation (also known as expandable foam), pressure-treated wood, marine-grade plywood, and ceramic tile. When a material is flood-resistant, it can withstand direct contact with floodwater for at least 72 hours without being significantly damaged.

If you notice standing water under the deck after rainstorms, you may need a drainage system to efficiently move this water. You do not want standing water to rest against your foundation or against support posts for the deck, as this could cause significant structural problems over time. Make sure the area has proper grading, too.

Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.

Standard homeowners insurance policies may cover basement water damage or flooding, but only if it is caused by a sudden and accidental event that is a covered peril, such as a burst pipe or a failing appliance. Damage caused by natural flooding from extreme weather, groundwater seepage, or heavy rain is typically excluded and requires a separate flood insurance policy. Some insurers also offer an optional water backup endorsement for issues like sewer backups. Review your policy or speak with your agent to understand your specific coverage.
