Our Geotextile Underlayment Fabric is consists of non woven
Polypropolyne stable fibers which are heat set and needle punched for
superior bonding. This extremely versatile underlayment fabric has a
very high tensile strength. The geofabric underlay has great physical
and hydraulic properties and is used for many commercial and consumer

WHY DO I NEED UNDERLAYMENT?
Can I use newspaper or old carpet?
- To answer those questions we need to know what exactly
underlayment is and what it does. A proper underlayment is considered a
“non woven Geotextile” That is a fancy term for saying it is a really
tough material that is lightweight and easy to work with.
- Underlayment has only one job and that is to protect your
pond liner. 45 mil Pond liner is very strong and puncture resistant but
it does have its limits. Using a 6oz thickness of underlayment can
improve the PUNTURE RESISTANCE of your pond liner by 400%.
- “I want to use newspapers for an underlayment.” Great, go
right ahead. Just make sure you test the thickness that you need by
stacking enough WET newspapers over a sharp rock that it does not poke
thru when you put 20,000 lbs on top of it! The average 2 foot deep pond
that is 11x16 foot will have enough water in it to exceed 10 TONS.
That’s over 20,000 pounds of water in your pond. If you use newspapers
as your underlayment you better stack them about 1 foot thick. That’s a
lot of Sunday papers folks!
- “I want to use sand for an underlayment” SEE ABOVE. Unless
you OWN the beach you are getting the sand from it is a BAD and
expensive idea to try and put enough sand down to protect your pond
liner from rocks hidden under the surface. These rocks will emerge over
time as the HUGE weight of your pond presses down on it.
- “I want to use old carpet for an underlayment” Got
allergies? No, well you soon will have. Yes, then stay away from your
pond all together as it will soon make you sick. Look folks, saving
money is my favorite past time but doing so at the risk of my health has
never been high on my list. Carpets are NASTY , DIRTY, BACTERIA FILLED
MOLD ATTRACTORS! And that’s when they are dry in your home. Now take
this same filthy used rag and put it under your pond liner where it will
sit wet and moldy for the next 10-20 years. In this case your fish will
be fine but as far as the people around the pond, their health is in
- Save money when it makes sense and spend money to ensure
your family and friends enjoy your new pond without the need for allergy
