The Formal Pond

The pond sits in the middle of the vegetable garden at the far end of our back garden. It acts a pivotal feature, sitting as it does at the centre of two crossing vistas. It was designed to look good from both directions. It consists, in fact, of two separate rectangular preformed liners, with the bridge coving the join. One pond has gold fish, and the other is given over to wildlife, providing the best of both worlds.


Originally this area was a large bed, used first for growing squashes and later for wildflowers. The idea of a pond came about in 2012 and construction started in that summer. By 2013 the surrounding paving was completed and it looked like this:

You can read about its design and build here.

Despite the ease of construction they afforded, I was never happy with the timber surround, partly due to its impermanence, but also aesthetically it looked a bit rough and ready. Furthermore, the liner was too visible, its green plastic detracting from the overall look.

Within a couple of years there were signs that the timber was degrading in places due to the high humidity, so I made plans to have the timbers replaced with proper brick edging.

All Change: Brick Edging

There were a couple of considerations here: first, brick would be permanent, and second it could overhang the liner so that the water appeared to run right up to the edge.

The plans I drew up are shown right (click to view full size)►.

Blue bricks would match those used on the greenhouse. Being laid as soldiers on edge, I envisaged them resting on the edge of the pond liner just millimetres above the water surface.

When we had the front garden hard landscaping completed in 2016, this was added to the brief. However, the landscape company realised (after casting the footings) that there was insufficient depth for a mortar bed without the bricks standing proud of the adjacent paving.

After a bit of head scratching we decided to go for bricks on their face thereby allowing space for a mortar bed. Red pavers were used as the blue bricks had holes and would not work in this arrangement. In some ways I was pleased as the matching colour made a nicer finish compared to blue bricks I now think. Here’s the results (early 2017):

It was OK, but… not what I’d hoped. I’m a stickler for detail and the edge beneath the bricks was bugging me.

Unfortunately, the additional thickness of mortar meant that the liner was almost more visible than before. Not what I had intended at all. I lived with this for a while, cleaned out the weeds, and topped up the water level, but I was not happy. The mortar really caught the sunlight and looked dreadful to my eye. Something had to be done…

Painting the mortar and liner

I drained the ponds a few inches so that I could get to the liner. Laying on my belly I cleaned the plastic and sanded the mortar smooth. Then I gave the liner and the mortar a coat of black paint. Here is the result:

The improvement was dramatic and gave the effect I wanted. A couple of coats and it looked like this:

The previously rough edges now magically disappear under the bricks, creating that mirrored surface effect that makes ponds so calm and inviting. The distracting plastic and mortar had been banished – Iit looked miles better even with the water level low. Once topped up, and given a couple of months to settle down the whole thing was clearly a success.
