Plastic & Tape

The most common way to encapsulate a crawlspace is with high quality plastic sheeting and tapes that are made and marketed for use in a crawlspace.   Often these systems will require the use of a large dehumidifier perpetually afterwards for one main reason – the seal you are looking between the pieces of plastic and the joins to concrete or pipe penetrations is only done with 4 inch tape.  Plastic and tape makes for an attractive photo, but does lack the longevity and initial seal of a high performance seamless system such as the Nu-Crawl System. Even high quality plastics cannot offer protection from puncturing. Let’s face it the gravel or rough concrete that may be under the liner will cut through pretty quickly if used for storage, or will occur even during installation.  The biggest flaw of plastic and tape systems is the tape used, because any tape relies on adhesives, which will fail over time due to moisture or drying, either way it is hard to expect a perfect job and expect it to last.
