What is the Nu-Crawl System?
A system specifically engineered for your crawlspace encapsulation project that doesn’t just use a plastic liner and rolls and rolls of tape.
You wouldn’t use a plastic tarp and tape as a permanent solution to a leaky roof and you shouldn’t use it in your crawl space and expect it to last. Equally, concrete is great for a driveway but in a crawlspace it will crack and let in moisture, so if the goal is a dry conditioned space concrete is not the right material.
Waterproofing Companies cut corners. The Nu-Crawl design team with decades of experience in crawl space encapsulation, construction and insulation knew there was a better way.
How it Works:
Nu-Crawl System: The Superior Crawlspace Encapsulation
Reflective insulation/vapor barrier on foundation, with 2" sprayed closed cell insulation sprayed into sill boxes and sealing top of reflective insulation.
The Nu-Crawl System is a proprietary, seamless crawlspace encapsulation solution that utilizes a custom-sprayed liner, engineered to provide a permanent and superior moisture barrier compared to traditional plastic liners or concrete. Unlike conventional methods that rely on tape or porous materials, Nu-Crawl is sprayed directly onto surfaces, creating a permanently bonded, 100% approved vapor barrier that cures in just 15 seconds. This innovative system offers exceptional durability, backed by a 100-year warranty, and requires no maintenance, ensuring a dry, conditioned crawlspace for over a century.
2.
Ground covered with foam board insulation underlay for comfort and insulation (Optional).
3.
40-60ml custom Nu-Crawl sprayed liner fitted onto ground, overlapping and along perimeter base and above footings.
4.
Sprayed seams and joins for a perfect seal and permanent reliability.
NO TAPED SEAMS!
What are the different crawlspace encapsulation systems available?
| Issues & Concern of Use | NU-CRAWL | Plastic & Tape | Concrete | NU CRAWL Distinction |
|---|---|---|---|---|
| Custom Made to Fit | ![]() | ![]() | ![]() | • Nu-Crawl is sprayed to fit onsite, making it seamless • Plastic and tape is piecemeal • Concrete is flowable and self-leveling on flat surfaces |
| Safe And Dry Storage | ![]() | ![]() | ![]() | • Nu-Crawl is 100% approved vapor barrier • Plastic and tape tears, leaks, and is temporary • Concrete is porous, allowing that results in mold |
| Durability | ![]() | ![]() | ![]() | • Nu-Crawl gives you a 100 year warranty • Plastic and tape punctures, tears and leaks from day one • Concrete is very durable |
| Easy to Maintain | ![]() | ![]() | ![]() | • Nu-Crawl never needs maintenance • Plastic and tape detaches and shifts • Concrete will crack and spall |
| Permanently Bonded at Contact Points | ![]() | ![]() | ![]() | • Nu-Crawl is sprayed onto columns, concrete footings, and pipes • Tape adhesives dry and also soften if wet • Concrete shrinks apart from edges after curing |
| Extremely Humid when Drying | N/A | N/A | ![]() | • Nu-Crawl is cured in 15 seconds and ready for use immediately • Plastic and tape are pre-made and ready to install • Concrete heats up and emits mositure when curing. This can go on for weeks after installation |
| Surface Needs To Be Graded Level | ![]() | | ![]() | • Nu-Crawl can be applied over any surface, even vertically • Plastic and tape will fail to gravity if applied over slopes • Without leveling, concrete depth can vary from too thin to too deep |
| Ground Needs to be Compacted | ![]() | | ![]() | • Nu-Crawl is flexible and soil compaction has no effect • Plastic and tape comes apart with large movement • Once concrete cures, the ground can drop, leaving the concrete to crack and shift |
| Code Required 4" Stone Base | ![]() | | ![]() | • Nu-Crawl can be applied over any surface • Direct contact with tape may cause failure. Stone may help • Residential codes stipulate concrete have a gravel layer for groundwater effects |
| Seamless and Complete | ![]() | | | • Nu-Crawl can join perfectly under any circumstance • Plastic and tape is inherently weak and won't adhere to slick surfaces. Tape also leaves air gaps. • Concrete is porous, and does nothing to encapsulate. The vapor barrier below concrete is weak and will shift. |
