Frequently Asked Questions

1. What is PVC?
Poly Vinyl Chloride (PVC) is the most commonly specified lining material in the industry. Manufactured by the calendaring or extrusion process, it is a highly flexible, non-reinforced, cost-effective, waterproofing geomembrane with many uses and advantages for the user. PVC has high puncture strength and excellent abrasion resistance. It is resistant to a number of industrial chemicals. Because of its high flexibility, PVC liners readily conform to sub grade contours and offer excellent interface friction without being textured.
 
2. What is the maximum size sheet for PVC membrane?

Sheets are produced as large as 40 feet in width. The use of a PVC liner prevents contaminants from entering groundwater sources or streams. In addition, it conserves potable water resources by preventing seepage loss. Narrower widths are also produced to offer applicators greater flexibility in positioning membrane.

Narrower sheets are also produced without factory seams (seamless) for use primarily in adhered and mechanically fastened applications. The major advantage of seamless material is the elimination of factory splice T-joints that occur when factory seams intersect with field splices. This reduction in T-joints significantly increases the potential for watertight performance by eliminating potential "water channels" into field splices.

 
3. What size liner do I need?

The formula for sizing a pond liner is:

(Pond Length') + (2 x Pond Depth') + (2') = Liner Length'

(Pond Width') + (2 x Pond Depth') + (2') = Liner Width'

So... if you want a finished pond that is 12' long, 7' wide, and 3' deep; then using the formula above, the liner size you need is:

(12') + (2 x 3') + (2') = 20' Long

(7') + (2 x 3') + (2') = 15' Wide

This basic formula will work for ALL pond shapes.

 
4. How many gallons of water is in my pond?

The formula for determining the number of gallons of water in a pond is simple.

(Pond Length') + (2 x Pond Depth') + (2') = Liner Length'

For Square and Rectangular Ponds:

(Pond Length') x (Pond Width') x (Pond Depth') x 7.5 = Gallon Size

For example, if you want a finished pond that is rectangular in shape, and is 12' long, 7' wide, and 3' deep; then using the formula above, the gallon size of your pond is:

(12') x (7') x (3') x 7.485 = 1,890 Gallons

For Oval Ponds:

(Radius1') x (Radius2') x Pi(3.14) x (Average Depth') x (7.485) = Gallon Size

For example, if you want a finished pond that is oval in shape, and is 12' at the widest length accross, 7' at the shortist length accross, with a 3' average depth; then using the formula above, the gallon size of your pond is:

(6') x (3.5') x (3.14) x (3') x 7.485 = 1,480 Gallons

 
5. How deep should I make my water feature?

For fish ponds, a depth of at least 18", or deeper is recommended. Healthy fish LOVE to move up and down, as well as side to side!

For water gardens, the water feature should have a depth of at least 12", or deeper.

Check your local fence requirements (building codes) and freeze line depth.
