SORRY, NO RETURNS ON CUSTOM CUT LINER

At TJB-INC, we always use the 4 oz. Underlayment before the liner is installed.  We had several bad experiences where we did not use underlayment and developed leaks in the stream liner when liner was walked on.  Underlayment would have protected the liner from the sharp objects in the soil from puncturing the liner.  So learn from our early mistakes, and protect your liner or wish later that you had!  

Liner Dimension Calculations for any type of water feature:
Length + 2x Depth + 2' Safety Overlap = Liner Length
Width + 2x Depth + 2' Safety Overlap = Liner Width

Water Garden Pond Liner Size

To calculate your pond liner size for a water garden pond:

Example:
Your Water Garden Pond is going to be 17' long by 12' feet wide, with a maximum depth of 2'.

Add "Double your Depth" to each dimension to accommodate the vertical walls in the pond. (2 x 2 = 4) So the dimensions adjusted for depth are now 21' long and 16' wide. (17 + 4 = 21 and 12 + 4 = 16)

Now add a "Safety Overlap" of 2' to each of those dimensions. (21 + 2 = 23, and 16 + 2 = 18). Your 17' long by 12' wide pond with a 2' depth and 1' of Safety Overlap on each side would need a 23' x 18' liner.

Liner is sold in 5' increments - so you would purchase a 25' x 20' liner for this pond.

Another example:
11'l x 8'w x 2'd Water Garden Pond
(2' depth x 2 = 4)

Add double the depth to each dimension and add 2' of Safety Overlap to each dimension.
11 + 4 = 15. For overlap add; 15 + 2 = 17 total length.
8 + 4 = 12. For overlap add; 12 + 2 = 14 total width.

Purchase a 20' x 15' Liner for an 11' x 8' pond @ 2' deep.
