How to Determine the Size Underlayment You Should Buy:
1.) Determine the total sq ft of your pond liner: Example 20'x30' = 600 sq ft
2.) Divide the total sq ft of your liner by 15 (this is the width of the rolls they come on): Example 600 sq ft / 15 = 40
Example: You would need to purchase a 15'x40' underlayment
