"Blalock waterproofing did a fantastic job in my basement. Cory came out, gave an estimate and completed the job of 60 ft of waterproofing in just 6 days. From estimate to completion in 6 days, amazing. He started on Monday and Wed. Afternoon, cleaned up and job down. He dealt with my stairs- they were in the way, and added some additional support to the 4x4s that had been rotted out from all the water at floor level. Final price was exactly what was estimated. Hire them!"

Basement Waterproofing questions, answered by experts

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.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

Crawl space encapsulation typically lasts between 10 to 20 years. If you experience a catastrophic event, like a flood, or poorly encapsulate your space with low-quality materials, it may only last a decade. Otherwise, as long as you properly maintain your crawl space, a high-quality encapsulation can last more than 20 years.

Below-ground shelters are the best in terms of durability, but there is a risk of flooding and obstruction. Modern technology and rigorous construction requirements make above-ground shelters a better option for accessibility, safety, and, usually, your budget. They may not have the same aesthetic appeal, but many of their features make above-ground shelters a better option.
