"They advice, and had all our questions answered on sensible and affordable options. Very knowledgeable, prompt, polite, efficient, and thorough team! We are happy with their waterproofing services in our basement (fast sump pump and a grate trench with a discharge line that goes 15 feet to the outside bubbler) as well as crawl space shield installed under our addition. It works well, and Pioneer checked a month later and a year after for inspection and cleaning. A+ work and workers."

"I recently contracted with Abalia Construction to finish my basement, and overall, my experience was great! Things that stand out for working with Khaled are his communication style, his ownership/creativity to meet the design in delivering the end-product and his efforts to keep our project timeline and budget. He brought fresh and innovative ideas to the table, transforming our basement into a unique space that stands out. The incorporation of creative elements added a distinct touch, making the final result more interesting and personalized. Khaled demonstrated an ability to manage time effectively, ensuring that the basement was completed within the specified period and provided a realistic cost estimate from the beginning which they stuck to. There were still some unforeseen delays to the project due to either material back-order or unavailability of workers, but still Khaled worked personally to keep the project on task and within reasonable time. Communication with Khaled was great as we were able to approach with any issues/concerns and he was able to have a logical cordial discussions to reach to an aligned position. He was responsive to queries and concerns. While the basement looks great quality there were still instances where attention to detail seemed lacking. The subcontractors and workers employed were also skilled professionals however their attention to details could have been better. Moreover, communication with workers/sub-contactors was little challenging due to fact them not speaking English. Clearer communication on these fronts could have mitigated some of the concerns I had during the construction process. However, Khaled overcame these challenges by taking an active role in addressing any issues even when it meant that he had to re-do some of the activities again, bringing his workers back, or even him spending long hours to complete the job to our satisfaction. In summary, Abalia Construction delivered a basement finishing project that showcased creativity and was completed within the agreed-upon timeframe and within budget all with an excellent communications. Without any doubt, they will be the first I reach out to for my next project."

"Hired them in August to repoint all of the foundation outside and about half inside of the basement (brick repointing) also added some waterproofing and everything looks great and I haven't had any water come in the basement as a result of Ben The Mason and his son's great work. Highly recommend them for any masonry project, we also talked about redoing my front steps which I will follow up with sometime in the near future."

"They did an excellent job repointing the exterior of my foundation and brick piers in the basement. I had a tight schedule and they worked through the weekend without me asking. Showed up early and worked long days to get it done. One of the guys was able to shimmy into a very tight and awkward spot due to the porch structure to get every area of the foundation. I pointed out a couple missed areas and they happily came back the next day to finish the job. I will be using them for future projects."

Basement Waterproofing FAQs, answered by experts

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.

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.

Water that pools under pavers can erode the soil foundation and weaken the paver structure. In some situations, it can also cause mold and mildew growth. If that happens, you may need to start budgeting for the cost to build and install a patio to replace the damaged one.

Overwatering can cause issues like water pooling and drainage problems. To prevent overwatering, monitor your soil levels on a regular basis and change your watering schedule as necessary.

If you set up a dehumidifier, it will usually dry out your wet crawl space within 12 to 24 hours. Once the space is dry, it’s a good idea to take preventative measures to keep it dry. These include installing a French drain or other exterior foundation drainage system, installing a sump pump in the crawl space, and installing a vapor barrier in addition to leaving the dehumidifier running.
