Installing a Pond Liner - A Comprehensive Guide

Installing a pond liner is the key to building a beautiful, natural-looking pond in any landscape. With this installation guide, you’ll have all the information and tools you need to easily install your pond liner and create the perfect spot in your garden or yard.


Preparing the Site for Installation.

Before installing your pond liner, you’ll need to prepare the site by removing any debris and leveling the surface. Next, mark off the shape of your desired pond with a garden hose or spray paint. Make sure it is at least 3-4 inches deep for adequate water clarity and to allow fish to thrive. Apply a layer of sand over compacted soil in areas where the bottom will have rocks or other hard landscape materials. Finally, install the edging of your choice along the outline of your pond.


Calculating Your Pond Liner's Dimensions.

To accurately estimate the size of your pond liner, you need to measure its length and width. Measure from the outside of the edging or wall to calculate the maximum range for both measurements. Also, be sure to include an extra few inches at both ends and sides of your pond liner in order to bury it when you install it. Finally, determine how deep your pond will be so that you purchase a pond liner that meets this requirement as well.


Placing and Setting the Pond Liner in Place.

Once you’ve purchased the liner and prepared your site, it's time to install it. Start by placing the liner over the pond area and make sure it is evenly spread out. To prevent wrinkles from forming in the liner bed, use a longboard or similar device to push them away from the sides and base of your pond. Additionally, try to keep any folds as even as possible for an optimal leveled look.


Finishing with EPDM or PVC Seaming Tape and Edging Stones Around the Pond Liner.

Once the liner is in place, finish and secure it with EPDM or PVC seaming tape. This tape acts like glue to adhere the edges of the liner together by bonding them and preventing water from entering any space between pieces of the liner. Additionally, after securing with tape, place edging stones around your pond to add a decorative touch and complete your project.


Tipping and Trimming Between Rows of Stones to Finish Installation properly.


After the edging stones are in place and leveled, you can finish your project by tipping and trimming. Tipping is when you point the top edge of each layer of stones downwards toward the pond. This gives it a professional look and also helps to discourage wildlife from entering the pond. Trimming requires an axe or chisel to shape any overhanging stone edges for an even smoother finished look. This can be tricky, so make sure to work safely when completing this step.
