Despite its name columns, this texture suits extremely well for walls and urns.
Concrete Plates
It is a concrete wall made of numerous concrete plates. Due to weathering, the concrete plates have cracks, pores and dirt.

Muddy Ground with Footsteps in Sludge
This is mostly a muddy ground having some footsteps on the squelchy sludge. A few heavier footsteps squish the mud deeper. It creates puddles everywhere.
Ground Covered with Gravel
This is a texture made of lots of gravel. It can be used as pavement for roads or to cover mud in backyard.

With your imagination, it could also be a wall texture.
Worn Wood Plank
This is a very raw wood plank. Due to aging, most of the planks are worn. It is made of rough type of wood that gives it a very bumpy texture.
Sand Ground with Wavy Pattern
That is a sandy ground such as beach. It has wavy patterns due to wind. Tiny pebbles can occasionally be found.

Simply put on this texture on a flat surface, you will have a beautiful beach!
Red Brick Wall Partially Plastered
It is a classic red brick wall. On the top is a thin layer of plaster that has a botched workmanship. Brush strokes are prominent. Besides, the plaster only covers some parts of the wall.
Dusty Black Cladding Ground Texture
It is a black cladding with a lot of dust and mud on the surface. There are also numerous worn and cracks on each cladding plate. Besides, pebbles scatter all over the ground.
Dry Muddy Ground Texture with Cracks Everywhere
This is a dried muddy field during a drought. After losing all the water, large and small cracks appear everywhere. There are small stones scattering around the soil.

This texture is great for texturing a non-irrigated farmland.
Exposed Aggregate Concrete Pavement Texture
It is exposed concrete aggregate pavement. Exposed concrete aggregate is commonly used as decorative concrete. The top layer of cement paste is removed and the underlying aggregate is exposed.

This kind of concrete is very durable and skid-resistant, so it is a great material for texturing sidewalks, driveways, pool decks etc.

It is also a good substance for rough walls.
Asteroid or Planetary Rock Ground Texture
It is a rocky ground surface which can be found on asteroids or outer space planets.

The planetary outer shell is badly hit by millions of meteors created numerous meteor craters.

Large craters have the shapes of volcanoes while small shooting stars leave a lot of dents on the bumpy bottom base.
Bumpy and Sandy Cliff Rock Texture
From its yellowish color, it tells us it is a sandy rock. Usually, this type of rocky materials can be found on cliff.

Yellowish spots also appear since this texture is a raw rocky material.

It is not a perfect green jade. There is subtle amount of yellow tint mixes with the precious green parts.
Tadao Ando Vertical Concrete Plate Texture
They are Tadao Ando type of concrete plate. Concrete 0008 is horizontally arranged while this texture is vertically organized.

Besides, these concrete plates has 8 holes while Concrete 0008 has only 4 holes.

Dirt can easily be seen on the surface.
Tadao Ando Type Concrete Plate Texture
