The NCS membrane is a Polyurea product. In Laymen’s terms, a hybrid
between epoxy and urethane developed for the waterproofing and protective
coating industry. This product is an amazing innovation in the waterproofing
industry. It was first used in the military and marine industry, but after
seeing all of the benefits and capabilities of being
able to expand without fracturing, it became recognized as a perfect fit for waterproofing residential and
commercial decks. It is also useful for buildings that are constantly
under stress, which can cause fractures in all previous membranes over
time. After years of testing and modifications, it is now the
premier choice of waterproofing membranes, but only a few chosen contractors have been certified and licensed and
approved to install the application.
So how does the new NCS Membrane stack up?
Pros:
- 350% elongation (tt will need to expand 3 ½ times surface area before
fracturing)
- Anti-fracture membrane cold and heat tolerances
- Performs below freezing conditions and exceeds 130 degree temperature
- Application areas can be back filled within a few hours
- Very little dry time
- Seamless solid surface membrane
- Hardness is a Shore D (460)
- It can be back filled without protection board
- Extreme tolerances to hydro-static pressures
- Very durable
Cons:
- Typically 25% more for installation than other conventional roll on coatings
Conventional waterproofing Membrane Materials w/ Protection Board
Pros:
- Material cost relatively inexpensive
- Readily available to most for applications
Cons:
- Anti- fracture elements far less than NCS
- Material application is layered in with multi-coats, so application takes
much longer
- Dry-time is 3 times the amount of NCS
- Minimal hardness and protection
- Must utilize protection board for back fill (sub-grade waterproofing)
- Multi-layered application allows for vegetation roots to impact between
layers for failure (sub-grade waterproofing)
This leads to the conclusion that the NCS-Subgrade Membrane is a little
more expensive up front, but in the long run will save you lots of money
in costly repairs in the future.
