Common Crawl Space Problems in Philadelphia & Surrounding Areas

Groundwater Intrusion

In a perfect world, crawl spaces would have built-in drainage systems, or they would be at least properly graded to prevent water from pooling in the space.

Often, however, that is not the case, and groundwater puddles in the crawl space which is always bad news.

Jamison Basement Waterproofing offers the most advanced drainage solutions for your crawl space.

High Humidity

Why are crawl spaces so prone to moisture? Well, it has to do with the very way they are built. The dirt floor in crawl spaces simply allows water to evaporate in the space, and the crawl space vents originally thought to allow moisture to dry, aggravate the problem by allowing humid outside air in.

Mold, Odors & Structural Decay

Every environment where Relative Humidity is at or above 60% is a breeding ground for mold and dry rot. Crawl spaces are notorious for having serious moisture problems that cannot be solved with vents, crawl space vent fans, or a thin plastic sheet on the floor to serve as a vapor barrier.

Jamison Basement Waterproofing crawl space solutions are based on the most recent building science recommendations.

Crawl Space Solutions

At Jamison Basement Waterproofing, we help our customers in Southeastern Pennsylvania by getting to the root of the problem.

• Crawl Space Drainage System - If there are issues with standing water, we begin by installing a drainage system installed prior to the encapsulation process. We then run this drainage system into our GrateSump™ liner, and install a sump pump to remove the water from the crawl space.
• DimpleShield Drainage Matting - A dimpled plastic material used on high footings or concrete floor to assist with crawl space drainage issues.
• Crawl Space Vent Covers - Most crawl spaces have been vented due to antiquated building codes. We now know that venting a crawl space creates big problems and it's necessary to seal any vents or areas where outside air can get in. We have patented crawl space vent covers to repair this issue.
• CrawlShield™ Encapsulation System - To complete the process of sealing the crawl space, we install a patented crawl space encapsulation system to completely eliminate vapors and odors rising from the ground; creating a layer of protection between the dirt floor and your living space which also helps in lowering your home's heating bills while making the living space more comfortable.
• Crawl Space Dehumidification System - After the area is sealed, the moisture level will need to be controlled and brought down to a relative humidity below 50%, using our high-efficiency dehumidification systems.

Crawl Space Repair & Encapsulation in Philadelphia & Nearby PA & NJ Areas

Homes built with crawl space type foundations in the years after WW2 were quite popular in the U.S. This system allowed homes to be built faster and more affordably than those with full basements. Additionally, they provided the needed access to plumbing, wires, and ducts. The problem is that builders did not take into account the issues that we know now. For example, the type of crawl space ventilation preferred then ended up creating more problems than it solved. Crawl space vents were a source of numerous problems including structural decay, mold, pests, and significant energy penalties.
