Slate patios
Use slate where its texture, colour and wet-weather character suit the setting.
Slate can create a strong, quiet surface in sheltered courtyards and planted gardens. Product origin, cleft, thickness, edge finish and water exposure vary, so compare the actual outdoor paving rather than relying on a dark colour swatch.
01
Inspect texture in dry and wet conditions
A slate sample can look and feel different after rain. Review surface relief, tonal variation and supplier information for the intended outdoor use, especially where the patio sits in shade or close to a frequently used door.
Riven or smoother finish
Calibrated thickness and unit sizes
Wet and dry appearance
Edges, steps and threshold pieces
02
Plan the bed, joints and water route
Variable units and strong colour make uneven support, residue and poorly resolved falls conspicuous. Agree the proposed bedding, joint colour, perimeter detail and drainage before laying begins.
03
Let maintenance reflect the setting
Leaves and organic matter linger in sheltered gardens. Ask for product-specific cleaning advice and keep runoff moving so the surface, joints and adjacent walls are easier to maintain.

Common questions
Before requesting an estimate.
Does black slate stay black outdoors?
Appearance can change with moisture, weathering, deposits and treatment. View realistic installed examples and ask the supplier what variation to expect from the selected product.
Is slate suitable in a shaded courtyard?
It can be, but shade, moisture, surface texture and maintenance all matter. Those site conditions should be discussed alongside the specific product information.
Can slate be used on steps?
Potentially, where the unit, support, nosing, geometry and surface are suitable. Steps should be detailed as a complete flight rather than cut from the patio layout at the end.
