Stamped concrete and exposed aggregate concrete give a Cornwall patio, driveway or walkway the look of stone, slate or natural pebbles on a single, solid slab. Cornwall Concrete Contracting installs both decorative finishes across Cornwall and Eastern Ontario. This page explains how each finish is made, how they handle winter, what they cost and how to keep them looking good.
What is stamped concrete?
Stamped concrete is ordinary structural concrete that is coloured and then pressed with flexible textured mats while it is still workable, leaving the pattern and grain of stone, slate, brick or wood in the surface. A release powder or liquid adds a second, darker tone in the low points so the finish reads as individual stones.
Because the pattern is pressed into a full slab, it does not shift or grow weeds the way loose pavers can. It still needs the same base, slope and joints as any slab; a pattern cannot hide settlement or poor drainage.
What is exposed aggregate concrete?
Exposed aggregate concrete is a slab whose top layer of cement paste is washed or brushed away after placement so the rounded stones in the mix show at the surface. The result is a textured, natural-looking finish with very good grip, which makes it popular for driveways, pool surrounds, walks and patios.
The look depends on the stone chosen for the mix and the timing of the wash, so we show you sample panels before the pour. Exposed aggregate hides tire marks, leaves and grit well, and a penetrating sealer helps it stand up to salt and stains.
How do you choose a stamped pattern and colour?
Choose a stamped pattern by its scale against the space and the house, and choose colour by matching the brick, stone or roof rather than a small sample chip. Large slate or ashlar patterns suit wide patios and driveways; smaller brick or cobble patterns suit narrow walks and borders.
Compare stamped patterns by looking at the size of each impression, the direction of the layout and the way borders frame the surface. Examples of decorative concrete in Four Corners can give you language for a design discussion. For your Cornwall project, share the intended use as well as the look you want so texture, edges and upkeep can be considered alongside appearance.
Is stamped concrete slippery in winter?
Stamped concrete can be slippery when wet or icy if it has a smooth texture and a glossy sealer, which is why we choose textured patterns for walking surfaces and add a fine anti-slip grit to the sealer on steps, walks and pool areas. Exposed aggregate is naturally grippier and is often the better choice where traction comes first.
In winter, a plastic shovel and sand are kinder to decorative concrete than metal blades and salt. Salt and repeated freezing are the main reasons a stamped surface fades or flakes, especially in its first season.
How much does stamped concrete cost in Cornwall?
The cost of stamped concrete in Cornwall depends on the area, the pattern and number of colours, borders and curves, and the same base and removal work any slab needs. Stamping takes a larger crew working against the setting concrete, so labour is the main difference from a plain broom finish. Exposed aggregate sits between the two in most cases.
A popular way to manage the budget is a broom-finished field with a stamped or exposed aggregate border, or decorative work only where guests see it. Your free written estimate prices the options side by side.
How should decorative concrete be sealed and maintained?
Decorative concrete should be sealed after it has cured and resealed every few years, when water stops beading on the surface or the colour starts to look dull. Sealer protects against salt, oil and freeze–thaw damage and keeps the release colour from wearing off in traffic areas.
Between sealings, sweep and rinse the surface, clean spills promptly and keep joints clear. Avoid pressure washing at close range, which can etch the surface and strip the sealer.
Compare the scale of the pattern, border width and colour against your home before choosing a decorative finish. Looking at stamped concrete in Catalina Foothills can help you describe a visual direction. Bring the features you like to your Cornwall project discussion so the finish, drainage and maintenance plan can be assessed for your own property.
Common questions about Stamped and Exposed Aggregate Concrete in Cornwall
Does stamped concrete crack?
Like any concrete it can crack, so joints are cut within the pattern to guide movement. A firm base and drainage are the best protection.
How often does stamped concrete need sealing?
Usually every two to three years, sooner on driveways and high-traffic areas or where salt is tracked in.
Is exposed aggregate good for driveways?
Yes. It hides tire marks, gives strong traction and handles traffic well when it is sealed and kept free of salt in its first winter.
