Monolith Water Features

Monolith Water Features


Adding a slate monolith to your garden can create an instant focal point and can also look like its has been part of your garden for several years rather than the more contemporary fountains which sometimes can look like they have been 'placed' into a garden.

When deciding on which size monolith to purchase we have a few hints and and tips which may help you decide.


Where in your garden will the monolith be sited? This determines the size and weight of the monolith. If you have an established garden and are looking to install a 6 foot monolith at the far end of your garden the chances are that this could prove very difficult without disrupting parts of your garden to get this into place or facing the costly option of craning the monolith into place. A 6ft monolith can weight up to 1 tonne (that's more than the average family car).

If your garden is still in the design stages installing a larger monolith still needs thought but is much easier when it comes to logistics as many landscape gardeners or builders can assist in manoeuvring into place, possibly using a mini digger or heavy duty lifting equipment. 

5,6,7 and 8ft monoliths cannot be placed onto a standard pre made pebble pool. Due to the weight they need to be installed onto a customer made pool with a galvanised grid. In most cases a base is built using breeze blocks with cross supporting sections. The pool can then be either lined with a heavy duty pond liner or painted with a sealant. On top of the pool a galvanise grid can the be placed, this is what the monolith will be sited on and once installed can be covered with pebbles or cobbles to disguise its appearance. The majority of galvanised grids come with an access hatch meaning that once he monolith is installed the pump and piping can still be accessed for maintenance when required.

The pump which will feed water to the top of the monolith needs to be submerged in the pool which has been created, the depth of this pool ideally needs to be at least 300mm to allow for the pump to be completely covered in water and evaporation during the hotter summer months. Most pumps come with 10 metres/30 feet of cable and can be wired directly in 240 volt mains supply (as with anything electrical we always advise that the pump has a RCD adaptor fitting for added protection).

Ribbed hose will feed from the head of the pump and travel up the centre of the drilled monolith, in most cases the pipe is pulled through the of the monolith then a small amount of PVC tape wrapped around the top before tapping back into the monolith to give a tight seal and prevent water flowing back down the inside of the monolith. Although in most cases when attaching the pipe to the pump the fit is quite snug a jubilee clip is advisory and will reduce the chance of the pipe becoming disconnected from the pump.

Once installed 6ft, 7ft and 8ft monoliths really do look spectacular and when water flows down both sides the sound is extremely soothing. 

Our most popular monolith is a 3ft drilled monolith in both plum and blue slate. Larger monoliths are ideally suited to commercial landscaping projects. Last year we supplied several 8ft monoliths to universities and public parks across the country. 

2 and 3ft monoliths can be installed quite easily. Both sizes can be installed using a pre built / off the shelf pebble pool. All you will need to do is dig a hole big enough for the reservoir, ensuring that it is level at the base (we would also advise adding a layer or aggregate or even concrete at the base to give extra support). The pebble pool can then be placed into the hole, the pump added and the monolith carefully positioned on top, finally the plastic lid can be disguised using either cobbles, pebbles or matching slate (plum or blue slate clippings).

All our monoliths are UK sourced, we buy direct from the quarries the monoliths are mined from and proud to support British companies. There are no two monoliths the same, every monolith differs in size, width, depth, the finish to the faces, all these aspects are one of the reasons why slate monoliths remain a popular choice when looking to add a water feature o your garden. 

UK Water Features stocks slate monoliths in the following sizes, 2ft, 3ft, 4ft, 5ft, 6ft, 7ft and 8ft. All monolith water features are delivered free or charge to the kerbside normally within 48 hours.
