Rendered Walls in Contemporary Garden Design
Rendered walls in the contemporary garden
It’s true we have spent the last 20 odd years making contemporary gardens most of which have had some sort of rendered wall within them
They are popular because they exude a certain style and sleek crisp minimalism
It has to be said that there are maintenance issues especially since most clients walls tend to be white or off-white.
Illustrated here is a simple cross-section of a typical rendered wall used as a retaining wall
It is essential to keep moisture and wet soil off the back of the wall to stop the masonry from becoming waterlogged with ensuing problems for the render on the front face of the wall
So it’s important to waterproof the back of the wall and to fill the back of the wall with some clean free draining material to allow water to soak into the landdrain and to be managed away.
There seem to be two types of render which are most popular today:
Sand and cement render where a 10 mm layer of mortar is applied in two layers to the front face of the wall The wall is then painted the desired colour.
The other type of render is the colour through render (K rend is a typical example)
These products are mostly textured and do not require painting
Problems with rendered walls
Firstly they can work out quite expensive A wall is built using concrete blocks or bricks and then rendered and of course there is a footing to go in beforehand.
Very often ( mostly on a rendered wall
Secondly it’s important to keep the front face of the wall from becoming damp
The damp front face of the wall can be subject to freeze thaw cycle and cold weather is control cause cracks and damage to the front face
We have experimented with rendered walls of all shapes and sizes over the years even curved walls to provide an interesting and dramatic affect
