Water$ave Plug & Seep FAQ

What is Water$ave Plug & Seep?

  • Water$ave Plug & Seep are a blend of super absorbent polymers of different sized particles similar to water crystals.

How does it work?

  • Polymer Innovations Water$ave Plug Range works by applying the dry polymer blend to the water surface of the water catchment area.
  • Once the polymers come in contact with the water it creates an invisible net that carries the polymers & any solids in the water downwards towards the leaks.
  • The different sized polymers then start expand up to 300 times it's size & head toward the voids, cracks & crevices where the water is leaking.
  • These polymers create a 'plug' & continue to expand filling all holes, cracks, crevices & porous soils over the coming days & weeks.
  • The hydrated polymers then become a part of the soil structure for decades.
  • Water$ave Plug Range is a blend of lineal & cross linked polymers that are 99% insoluble, non toxic & biodegradable. It will not harm any plants or animals like fish, yabbies, your pets or livestock.
  • This polymer is known as a Polyacrylamide. A combination of two monomers, Acrylamide & Potassium Acrylate. It’s charge density & molecular weight can be controlled by the ratio of Acrylamide & Potassium Acrylate.
  • This allows us to customise its charge depending on the soil to be bonded. This is known as flocculation, where soil solids are bonded into 'flocs'.
  • Water$ave locates the leak & seals it! Even if you don't know exactly where the leak is our polymers will locate the outflows.

Which blend Plug or Seep?

  • Water$ave Plug is designed for earthen dams, ponds or canals that contain soil crevices & cracks that are generally wider than 4mm.
    • Plug hydrates & expands up to 300 times it's particle size.
    • Plug is perfect for walls & bases with soil types containing:
      • Granite
      • Slate
      • Shale
      • Gravel
      • Conglomerates
      • Boulders
      • Pebbles
      • Exposed soils w/ holes, cracks or tunnels.

  • Water$ave Seep is designed for earthen dams, ponds or canals that contain fine soil crevices that are generally narrower than 4mm.
    • Seep hydrates & expands up to 200 times it's particle size.
    • Seep is perfect for walls & bases with soil types containing:
      • Loams
      • High Clays
      • Decomposed Granite
      • Sand
      • Silts
      • Basalt
      • Limestone/Sandstone
      • Sandy Clay Loams
      • Black/Red Clays
      • Alluvium/River Soils
      • Volcanic Soils

Can it be applied to dry dams or ponds?

  • No, because Water$ave Plug reacts with water you need to have at least 1m depth of water in your dam to treat it.

When should I treat the dam/pond?

  • If your dam has water in it & is currently leaking water then now would be the best time to apply Water$ave Plug.
  • The pressure of the water & the leakage creates the suction needed to draw the polymers into the problem areas.
  • If you do not have any water in your dam yet, you can apply Water$ave Plug as your dam is filling up as this ensures a neat & even coverage.

When is best time of day to apply it?

  • It is best applied during a quiet morning at low wind times so the product is not blown away during application.
  • Be sure that there is little to no wind or rain & that there is no water overflowing from the dam.

I know where the leak is. Can I apply the WaterSave to that area or do I have to treat the whole dam?

  • Yes, if you know where the leak is then you can concentrate your application to that area but it is also recommended that the rest of the dam be treated as well & this can be done when the dam is full or is at least above the problem area.

How do you apply Water$ave Plug & Seep?

  • Please visit our How To Apply Water$ave Plug & Seep page for more information.
  • Application is at a minimum rate of 100gm per m2 and should not be broadcast further than 1.5 metres by hand or fertilizer spreader.
  • Broadcast the polymer no more than 1.5 metres, a boat is recommended to make sure that the application is spread evenly all over the dam without spreading the blend.
  • Be careful not to separate the blend or go through the polymer while applying to the water surface.
  • Distribute it as if you are 'feeding the chickens' at the recommended rates.

Is it safe for plants, fish & animals?

  • Yes, it is 100% safe to use in dams where livestock are present.
  • Please remove any livestock that is occupying the affected areas.
  • Water$ave is biodegradable, non toxic & environmentally friendly.
  • If ingested, the acid in the stomach will start to break down the gels & the water is released into the stomach, the polymer beads are then passed through.

How much area does the 19kg pail treat?

  • A 19kg pail will treat approx. 180m2 when applied at the recommended rate of 100gm per m2.

How much Water$ave Plug will I need?

  • A minimum of 100g per m2 calculated on the surface area of your dam, depending on whether your dam is full or partially full.
  • You can work out how much product is needed by using our online Water$ave Plug & Seep Polymer Calculator.

I have tried liners & bentonite clay but my dam still leaks. Will Water$ave work better than bentonite?

  • Clients that have tried sealing their leaking dams with linings or bentonite without success have great results using Water$ave Plug.

Will my dam be sealed on first application? How many applications will I need?

  • In the vast majority of cases clients successfully seal their leaking dams on first application but in some cases further application may be required.
  • These instances occur usually when rare, unforseen circumstances have been encountered or there has been a lack of adequete information regarding the leak before hand.

How long will it take to work?

  • Allow 24 - 48 hrs to hydrate & sink towards the outflows.
  • Then allow 2 - 10 days depending on the rate of leak for the polymers to start incorporating into the soil structures. Some clients have had their dams sealed within a few days.
  • On average you could have your dam sealed or notice the slowing down of water loss within 3-7 days!
  • If your dam is still leaking after this time further applications could be necessary.
  • Please Contact Us if there has been no change there may be something we haven't considered eg. tree roots.

What if it does not stop my dam from leaking after 2 weeks?

  • There may be a few factors to consider that may have an influence on why your dam is not sealed.
  • Has the leak slowed down or is there any noticeable change in the leak?
  • Was the recommended amount used and was enough product applied to the dam?
  • Were the dam measurements correct?
  • Have there been any other changes to the dam or area since the first application?
  • There may be a more severe problem than first thought & further applications may be required.

Will it work if my dam has weeds? Do I need to remove the weeds first?

  • Weeds will inhibit the flow of the polymer into the soil.
  • The polymer needs a clear path to the soil, if you have any weeds, reeds, leaf, litter or deep slit, you will need to remove these before application.
  • Water$ave Plug & Seep is made up of different sized hydrating particles & they will be sucked into those areas.

How long will it last in the dam? Is it permanent?

  • Water$ave under normal conditions will seal for decades.
  • With ongoing trials we anticipate that this is a permanent solution to sealing leaks & ponds.

Who has used it?

  • Our Water$ave range has been used successfully worldwide from Canada, The United States, New Zealand, Europe, South Africa & Zimbabwe.
  • In Australia, The Department of Land/Soil Conservation have used it in the field for years with great success.
  • It has been used by farmers, fisheries, government departments & councils through to mining & construction companies.
  • Due to it's versatile nature & ability to customise to specific environments we believe it will be suitable for most situations & scale.

What is the success rate?

  • Some cases require further applications due to unknown or undefined problems.
  • Most dams and ponds are sealed with one applicaiton only

Does it work on all soil types?

  • Between the two Water$ave Plug & Seep blends, generally yes.
  • High levels of alkalinity, salinity or acidity may affect the product's performance however.
  • In these rare cases the blend can be altered to suit your specific conditions.

Can I apply it to a new dam that I am building?

  • Yes, Water$ave has been designed to apply to new as well as already constructed dams by applying it to the base & walls of the dam depending on the location of the leak.

Will you guarantee it will seal my dam?

  • No. Due to unforeseen circumstances & the nature of the problems we are unable to guarantee that this product will always work first time.
  • Further applications may be necessary & we do encourage you to communicate with us if you are experiencing problems with sealing your leaking dam so we can get the best possible results for your team.


Recently got 2 pails of your product; fantastic only evaporation is drinking the water. Thanks for advise from Mark. Great stuff , I’m spreading word.

I used your product recently to seal a dam & the results were astoundingly good. I am very impressed with this product.

- Michael Wilson

This product is Amazing !! I sprinkled about 1/3 of the pail into the leak area and within 12 hours it had expanded and sucked into the holes through all the gravel ! It is actually down to the smallest trickle now and we just had a huge rainst...

- Duane OHIO, USA

It's been almost 2 months since I treated our pond with your product.  We have had about 6 inches of rain since and the pond looks great.  The wetness below the dam is gone and the water level is holding. Bottom line is I am very impressed with...
