Marshalls Argent Smooth Paving Slab 600x600mm

In-Depth Look

The Argent range is a pressed concrete paving range from Marshalls, targeted at residential patios, paths, and courtyards where a clean, contemporary appearance is the priority.

Construction and Finish

The 38mm thickness gives good rigidity, and calibrated thickness is consistent from slab to slab, an important factor when laying on a sand bed, as inconsistent thickness forces constant adjustment of levels. The smooth finish gives a uniform colour across the patio, without the texture variation found with exposed aggregate or brushed surfaces.

Installation Considerations

These slabs are heavy, so the 600x600mm format requires two people to manoeuvre safely on site. Check the Marshalls specification for intended use, and follow the Marshalls laying guide for bedding and jointing.

Slip Resistance

The smooth finish provides adequate slip resistance for pedestrian use in normal conditions, but for steps, ramps, or areas that remain permanently damp, a textured or riven finish is preferable.

Installers

Ask the installer for their terms in writing.

Verdict

A clean concrete paving slab from Marshalls. The calibrated 38mm thickness and smooth contemporary finish make it a practical, attractive choice for residential patios and paths.

How It Compares

Marshalls Argent Smooth is a 600 x 600 x 38mm pressed concrete paving slab with a smooth, even finish. It is listed with a calibrated thickness, which helps keep a laid surface even. The product information describes it as a concrete slab for patios and paths, and it is a heavy item that needs careful handling.

Marshalls also sell other paving, including porcelain in the Symphony range and natural granite in the Eclipse range, and each has its own look, sizes and laying method. Compare current data rather than assume similarities. The real choice is often between materials: concrete, natural stone and porcelain.

Concrete is a practical, widely used choice. A consistent colour and smooth face give a modern look, but a smooth surface can become slippery when wet or covered in algae, so shade and damp areas deserve thought. Natural stone has more character and variation, and porcelain usually comes with its own laying instructions from the manufacturer.

Whatever you choose, ask the supplier for the manufacturer’s laying guidance for that exact product, because the correct bed, jointing and use can differ between ranges. The product information describes the Argent for patios and paths and lists it as heavy, so confirm the intended use and any limits, for example for vehicles, on the Marshalls specification.

Ask any installer to give you their terms in writing, and look at examples of their finished work. A good surface comes down to the preparation as much as the slab.

Common Questions

How should I lay 600x600 slabs on a patio? Dig out, lay and compact a suitable sub-base, then lay the slabs on a mortar bed with a fall for drainage. Keep joints consistent and fill them as the manufacturer advises. The Argent is a heavy slab, so lift with a second person or a slab lifter. Follow the manufacturer’s laying guide for the exact method.

Will smooth paving get slippery or green in shade? Any paving can grow algae in damp, shady spots, and a smooth finish may feel slicker when wet. Good drainage, sunlight and regular cleaning reduce the risk. If a path or step is always damp, consider a textured product instead, and check the slip resistance information from the maker.

How do I clean and seal it? Brush off loose dirt and wash with water and a suitable cleaner, using a soft brush. Take care with pressure washers, as high pressure can mark a surface. Sealing is optional and depends on the product. Check Marshalls’ care guidance first and test any cleaner or sealer on a spare slab or hidden corner.

How do I stop water pooling against the house? Build in a gentle fall away from the building and keep the paving surface below the damp proof course so splashing water cannot bridge it. Check that drains and gullies are not blocked. For levels and drainage near a building, ask the installer or building control for advice on your property.
