Compac HPS Petra Bosco

Petra Bosco features a light grey background, which creates a clean and modern visual atmosphere. The surface is then enhanced with medium-sized brown terrazzo particles, which create a warm and earthy texture. The particles are distributed evenly across the surface, and their organic shapes and varying shades of brown add natural and organic visual interest to the worktop. The combination of the light grey background and the warm brown terrazzo particles creates a contemporary and inviting aesthetic, making it an excellent option for modern interior and external design styles.

Colours and Pattern Variations

Important Disclaimer
Materials such as quartz, sintered porcelain, terrazzo, and solid surface may display natural or production-related variations in colour, tone, pattern, and surface characteristics. These variations are inherent to the material and may differ between batches.

Please note that images shown on our website are for illustrative purposes only. While they offer a general indication of pattern and colour, actual appearance can vary due to screen settings and batch-specific differences.

Customers are encouraged to carry out their own due diligence prior to purchase. No guarantee can be made that a sample, online image, or unreserved slab will exactly match the final product or any existing installation. Whenever possible, we recommend viewing and reserving specific slabs in person and referring to individual product pages for additional information or supplier documentation.

Tough

Quartz is one of the hardest minerals in the world. This makes our products very durable, with a high level of resistance.

Bacteria and mould have nowhere to take root. When it looks clean, it really is clean

Easy to clean

With a non-porous surface that prevents dirt and stains from penetrating the material. Marks and stains stay on the surface and can easily be removed.

Edge DETAILS

Enhance the finish of your quartz worktop with our precision-crafted edge profiles. Designed to complement both modern and traditional interiors, our edge details add a stylish, seamless look while maintaining the durability and hygiene benefits of solid surface materials.

Choose from a range of elegant profiles to suit your design preferences and achieve a truly bespoke result. Each edge is expertly fabricated to ensure a smooth, long-lasting finish.

Return End Styles

Return ends are custom-shaped finishes applied to the exposed edges of the worktop. They’re designed to provide a polished, continuous look where the surface terminates—whether against a wall, cabinet, or open space.

Each return style serves a specific purpose, from creating standout design features to accommodating architectural details or practical use cases. Whether you're planning a flowing curved end, a distinctive break front, or precision notching for cabinetry, these return styles ensure a tailored, high-quality finish.

Explore the full range below to find the perfect return style for your project.

Angled Return - A sloped return end typically used where the worktop meets a diagonal wall or feature.

Break Front - A stepped-out section on the front edge, often used to highlight a sink or hob.

Corner - designed to wrap around an internal or external corner section of the worktop.

Curved - A smooth, rounded return at the end of a worktop run, ideal for softening hard lines.

Double Notch - Features two cut-in sections - commonly for cabinetry or appliance integration.

Double Radius - Rounded corners on both sides of the return, often used in island or peninsular designs.

External Splay - An outward-angled return, typically to follow a wall or open-plan feature.

Full Return - A complete drop-down return from the top surface to the floor or unit base.

Part Return - A partial drop — used for visual effect or mid-height termination.

Single Radius - One rounded corner for a smooth transition at the end of a worktop.

Splayed Break Front - A stepped and angled feature that creates visual interest and ergonomic depth.

Triple Notch - Three stepped cutouts, typically custom-made for complex cabinetry layouts.

Square & Coved Upstands

Upstands are an essential element for achieving a refined and practical finish where your worktop meets the wall, offering protection against splashes and spills while creating a seamless transition between horizontal and vertical planes. Square upstands provide a sharp, modern look with a defined 90° junction, and are fixed on-site using special glue or silicone. Fabricated to exacting standards to ensure a good match with your quartz worktop. However, it’s important to note that upstands are made in a straight line, and any imperfections or large variations in the wall profile can leave gaps, which will need to be filled with decorators’ caulk. To achieve the best result, plastering or tiling should be completed after the worktops have been installed, ensuring a polished, professional finish.

Cutouts & Drainer Grooves

Custom cutouts and drainer grooves add both functionality and finesse to your solid surface worktop. Whether you're integrating sinks, hobs, tap holes, or pop-up sockets, each cutout is precisely machined to suit your specifications and seamlessly finished to match the surrounding surface.

Drainer grooves can be added for both style and practicality—angled or flat, they channel water efficiently back into the sink while enhancing the clean, bespoke look of your kitchen or utility space. Every detail is carefully crafted to maintain the durability, hygiene, and elegance of your worktop.

Technical Information

Overhangs and End Panels
Quartz Worktops must be supported every 600mm.
Maximum recommended overhang is 300mm. Greater than 300mm requires steel support.
Solid underside wrapping is recommended on overhangs or end panels when MDF substrate is visible beneath.
Due to the weight of quartz worktops, it is essential that your units are level and securely fixed.

Sinks
Because quartz worktops are fabricated to give a seamless appearance, it is also possible to install sinks and bowls from the same materials for a smooth and elegant finish.
A minimum of 70mm is required between sink cut-outs.
If a waste disposal unit is fitted to an undermounted sink after installation, additional support will be required, otherwise your warranty may be invalidated.

Hobs and Splashbacks
Splash backs or wall cladding are installed with a minimum 50mm gap behind an electric hob and a minimum 100mm gap behind a gas hob. There must also be a minimum 50mm gap from the cutout to the front of the worktop. To accommodate these requirements, it is sometimes necessary to widen the worktop to what is called a “breakfront.”

Sink cutouts are placed a minimum 50mm from the worktop front edge
A minimum of 120mm is required between two hob cutouts
A minimum of 100mm is required between hob and sink cutouts
A minimum of 70mm is required between two sink cutouts
If a waste disposal unit is fitted to an undermounted sink after installation, additional support will be required, otherwise your warranty may be invalidated

Domino Hobs – for structural strength allow 50mm for the splashback and 120mm between the hobs

Care & Maintenance

Scratches
Quartz worktops are highly scratch resistant but not scratch proof and the surface must be protected by chopping or cutting boards. Dark colours will show scratches.

Staining
Quartz worktops are incredibly hard and non-porous and will not absorb liquids, but it is still possible that grease, wine, coffee, nicotine, fruit juices and other strongly coloured substances can stain the surface if not properly protected or if the spills are not cleaned up immediately.

Hygienic
Quartz is naturally hygienic as it is non-porous.
