What Size Pond Liner Do I Need ?


Measure from a Plan

Length of liner required = Max. length of pond + (2 x max. depth of pond) + min. 2 feet (min. 60 cm) overlap

Width of liner required = Max. width of pond + (2 x max. depth of pond) + min. 2 feet (min. 60 cm) overlap



Measure off a Completed Excavation

If you are measuring off a completed excavation, use a flexible measuring tape or a rope that completely conforms to the contours of the excavation.

To determine the full length of liner required, run the tape or rope down into the pond, exactly following the contours of the excavation, across all the ledges, to the bottom of the pond, and back out the other side.

Then add at least 2 feet or 60 cm (minimum 1 foot or 30 cm per side) to allow for sufficient liner overlap outside of the pond.

Use the same method to determine the width of the liner.

Be sure to measure across the maximum length and width and at right angles to each other.

Example

Using one of the above formulas and including a minimum liner overlap of 2 feet (60 cm) for both length and width, you determine a required liner size of 19' x 23'.

Now all you have to do is select from either Firestone or Carlisle and look for a suitable size. In this case, the only suitable liner size is 20' x 25'.

PONTEC BMF UV Pond Filters

ONLY $ 249.98

Everything seems to be working fine and the pond looks great! Many thanks.
Maureen, Drayton Valley, AB

All the equipment arrived safely and was installed. I was a little concerned in the beginning as the water was spilling out over the filter. After a short time though it stopped and has worked fine ever since. I would like to thank you for all the time you gave to me in helping me make my decision. I appreciate it very much. I am sure at this time of the year you are very busy. I will tell you that I will be quick to recommend you to anyone who is looking for advice on water garden equipment. You deserve a "pat on the back" for providing the kind of service you gave me, Thanks again

PONTEC Marathon Pumps

STARTING AT ONLY $ 49.98

I received the Pontec Marathon 650 and hose kit yesterday and have installed it already - quite as expected (it's quite a 'gusher', I like the wrap-around cage to screen out large debris, and also the thermal overload protection) and I appreciate the fast service and low price.  Around here, much smaller capacity pumps alone cost much more - and with you I got the hose too!
Mike, Ridgetown, ON

I couldn't be more pleased. The pump (Pontec Marathon 800) is exactly what I needed. It arrived in only 2 days which is excellent delivery by any standards. I am delighted with your service and I will recommend you folks to everyone in search of pond products. Take a bow!

I've dealt with you folks on at least two previous occasions, and each time the service quality including concern resolution has been the best it could be. Thanks again so much for the extraordinary service....you certainly have gained my loyalty. I'll be back and hopefully the transactions will be much more straight forward in future. God don't make better pond people! Kindest regards,
John, Cranbrook, BC
