Yorkstone
Most of Britain’s cities are paved with this hardwearing
fine-grained sandstone. The color, which darkens when wet,
depends on where it was quarried in Yorkshire. Reclaimed
and composite paving slabs with a nonslip, riven surface
(as shown) are available. Consider sealing.

“Green” cement
The chance to emply greener, cleaner landscaping materials
is an exciting prospect. A new cement, which decomposes air
pollutants by means of a photocatalytic reaction, is being used
to make composite stone. When mixed with recycled granite,
it produces a hardwearing surface that helps improve air quality.

Sandstone
Made up of small mineral grains, sandstone is easy to cut
and lay. The import market has made available a wide range
of colors and patterns, including streaking and stripes. The
color darkens when wet. Reclaimed sandstone paving is a less
expensive option. Sealing is advisable. Available as composite.

Slate
Stylish and modern, slate is a hardwearing fine-grained stone.
Unless polished, it’s nonslip, even when wet, making it ideal
for pathways. Note the color darkens when wet. Various surface
textures are available, including rough cut (visible saw marks),
sandblasted, and polished (called honed). Consider sealing.
$$–$$$ ww e black, blue-gray, green, purple
Travertine
Popular as a building material since Roman times, travertine
is a dense form of calcium carbonate. Pure travertine is white,
but impurities add color. The characteristic pitting is caused
by gases trapped in the molten rock. The best quality
travertine has smaller holes that are infilled and polished.
$$–$$$ ww e white, pink, yellow, brown
Granite
A popular stainproof surface for kitchens, polished granite is
diamond-hard and tough enough for use in the garden. It
comes in a huge range of colors; some also include speckled
and streaked detailing. Affordable composite and terrazzo
(granite chips bonded with cement and polished) are available.
$$–$$$ ww e black and greens to pinks, reds, cream
Limestone
A sedimentary rock, limestone often has shells and fossils
embedded in it. Riven stone (shown here) is popular in
gardens because it is split in a way that leaves a roughened,
nonslip surface. Limestone darkens when its wet and it can
stain, so consider sealing it. Available as composite.
$$–$$$ ww e gray, white, pale red, yellow or black
Marble
More familiar in sunnier climes, marble is increasing in
popularity as a sophisticated landscaping material. When
polished, it has a lustrous quality that will smarten up any
patio. The characteristic veining is caused by mineral
impurities. Consider sealing. Available as composite.
