There’s nothing more calming than the tranquil sound of water trickling from a water feature and I can’t think of a better way to great guests to the house than having one right by the front door!
Now that Spring is here, it’s a great time to start thinking about adding some curb appeal by installing a pond. Ready made ponds are a great convenience. Here’s one we installed on one side of our front walkway. Following below is a complete tutorial with the lowdown on how we did it!
It is a simple and straightforward task to add a ridgid liner to the garden, but there are other considerations when the liner is going to be up against the edge of a walkway (as ours was). We ran into several challenges and I’ll show you how we resolved them.
But first, if you are installing a liner anywhere else in the garden, here are the general instructions. However, if you want to install a liner that will be intersecting with a walkway (like ours did), skip down to “Walkway Challenges”.
We started with a small kidney shaped pre-formed ridgid liner. It was very easy to install with a few simple tools and supplies (shovel, garden hose, sand, scoop, level). We placed the liner where we wanted it and then, using a hose, we marked out the outline of the shape (you can use marking paint or sand to mark also). We carefully measured the depth needed and also the depth and placement of any shelves we would also need to dig out (we have one shelf in our pond).
We dug out a hole to the shape and depth we measured and checked to make sure it was level once the liner was placed into the hole. Then we pulled it out again and added a few inches of sand to the bottom of the hole. This will help nestle the liner into the ground and keep it level. Keep adding sand until the liner stays steady without any rocking motion. It’s a good idea to tamp the sand down over the dirt on the bottom so the liner is seated securely. Continue to put the liner back in and check for level as you build up the sand. Making sure the pond is level is the most important step because water won’t stay securely inside the liner, where it belongs, if it’s tilted at all.
Once you’re satisfied with the fit, start to fill the liner with water from a garden hose and continue to make sure the liner is sitting level as it fills. If you notice any puckers in the liner, you’ll need to backfill with some of the dirt you removed to fill any air pockets (you can also use some sand). This is especially important underneath any shelves as you don’t want the liner to buckle under the pressure of the water – the liner needs solid support, both underneath and all around the sides!
When the liner is filled about halfway with water, backfill around all the edges with sand. We used a plastic hand trowel to direct the sand where we wanted it. A deep dustpan works well for this purpose too — place it away from the gap between the side wall and the liner (under the lip), then brush the sand into the gap to fill up the sides and secure it all around the edges.
We purchased some flagstone to hide the edges and finish it off (more to come about that in the next section).
For more about liner options and installation, here’s an excellent video to watch.
When we first installed our liner it was with the recognition that one day we would be installing new paving stones. We actually ended up doubling our work because of that; we had to re-support the pond when we updated the walkway. This is how the walkway looked before we installed the new pavers. As you can see the liner is level and sits on top of the stone slab.
To dress is up, we bought natural flagstone and placed it all around the edges of the liner to hide it. Be sure to buy different thicknesses so you’re able to stack it up to different levels since you’ll have higher gaps in the back and side than the front where it meets up with the walkway!
Here’s how the pond looked before we updated the walkway with new pavers. It looked quaint, but there was still lots of room for improvement; we knew we could do even better!
Notice that the flagstone around the edge looks a little skimpy? That’s because we didn’t buy enough initially. It’s sometimes hard to judge how much you’ll need until you’ve got the stone on site! Oh well, just be prepared to take another trip back to the stone yard. Between our front and back yards, we were on a first name basis with everyone at the stone yard by the time we were done!
When we finally got around to updating the old stone on the walkway from concrete slabs to pavers (before and after shown below) we wanted to be able to easily pull the liner out of the hole so we could power wash it each Spring and then put it back, ready to fill with clean water.
Easy upkeep and maintenance is always an important factor to us. Our biggest challenge was figuring out how to remove the liner without disturbing the base underneath our pavers and having it all crumble into the pond each time we lifted it out.
My husband and I put our heads together and came up with a brilliant idea using some concrete blocks, construction adhesive and some metal edging that we had left over from installing our walkway. Once you read through the following instructions, it will all make sense!
Since our liner was already installed as outlined above, our first step was to set up string lines so we could determine the finished level of the walkway and where we needed to place concrete blocks to fall just under the lip of the liner. Then we dry fit the concrete blocks around the front edge of the pond where it was going to intersect the walkway. We needed to stack the blocks two-high in order to get the height we needed. We kept taking the liner out and putting it back in as we dry fit the stones to ensure it would sit level once the stones were in place. You might have to add some sand into the bottom of the hole at this point to make sure the liner nestles properly.
I know this looks like a mess, but stick with me here!
Once you’re happy with the arrangement, use construction adhesive (rated for outdoor use) to glue the underside of the upper blocks to the bottom layer of blocks. Gluing them together is important as you don’t want anything to shift; the top stones also act as a base for the metal rim still to come.
Keep adding construction adhesive until all the stones have been glued into place.
Let the construction adhesive dry. Since our pond was done in two stages, it wasn’t necessary for us to add any dirt or sand around the sides, but if you are building yours from scratch, this is the time to make sure you’ve supported the bottom and sides with dirt and/or sand and leveled it as in the general instructions described above. Do this BEFORE you proceed to the final step.
We used the metal edging as a frame of sorts: we bent it until we got the exact shape of the pond. Temporarily tape it together to make sure that the pond can easily slip in and out of the metal frame. Make any necessary adjustments then connect the two edges in the middle by either riveting or screwing it together with a nut and bolt to hold the shape. Place the metal frame with the pond liner into the hole, then tape it down in a few spots to hold it against the concrete blocks. Gently lift out the liner so you’re only left with the metal frame sitting on top of the concrete blocks. Glue the metal frame to the concrete blocks at each tab (removing the tape as you go).
There – you’ve got a metal frame that acts as a ‘lip’ to prevent the fine stone gravel that forms the base of the walkway from falling into the pond each time it’s lifted out and replaced again (we used high performance bedding stone or HPB for short)!
If you like, you can pack a little dirt under the rest of the tabs if there are any gaps (make sure you don’t skew the level) and drive a few spikes into one or two of the them to secure the metal around the edges that aren’t glued down. This isn’t really necessary, however. You’re not trying to support the weight of the pond with the frame (that work is supposed to be done by adding and tamping sand in the bottom of the hole as described in the general instructions above). As I mentioned, the metal is simply acting as as guard between the walkway and pond to prevent migration of the HPB into the hole.
All that’s left is to fill up the rest of the walkway with the HPB base and cover up the concrete blocks to just below the lip of the metal (below you can only see evidence of the blocks in the hole itself).
Our final step was to screed the HPB to the final level and install the new pavers.
Here’s how the pond looks now: all dressed up, complete with pond plants and turtle spitter. We bought a variety of different thicknesses of flagstone and REALLY beefed it up all the around the edges since our first attempt. Isn’t it MUCH better than it was?!
To finish off the vignette, I built this trellis.
In the fall, leaves and dirt make will their way into the pond, but we’re not so fussed about it because we know that we can lift it out in the Spring and hose it down! We simply put away the pump and then add a wooden board over the top of the pond to keep the snow at bay.
Here is how the pond looks over the course of winter (we didn’t have snow when I took this shot!).
With a little innovation on our part, the liner has been a breeze to pull out in the Spring, clean up and then reinstall – ready to shine as the star of our small front garden 🙂
To keep mosquitoes at bay (they can’t breed in flowing water), make sure you run a spitter and pump to recirculate the water. You’ll need a source of electricity close to the pond (our main source was in the garage on the other side of the wall) and a weatherproof box that’s rated to be near water. Consult or hire a licensed electrician to ensure it’s all up to code.
We haven’t had any problems with algae growth in our little pond as it’s fairly shaded throughout the day; however if yours is exposed to a lot of sun, barley straw works wonders against algae.
By the way, the walkway was the very first paver project that I had ever attempted (and I installed every block myself)!
It was my ‘practice run’ for the travertine pavers we did in the backyard (here’s how that project looked in progress). To see how we landscaped our entire back yard, click here.
I have one more pond project coming up in a future post, so stay tuned. Here’s a sneak peek at the water feature I’ll be featuring that we built in the backyard.
Are you ready to attempt a water feature in your own garden?
