Product details

Antique Flagstone Paving

There are many period and traditionally styled homes, properties and gardens in Britain that require congruous and compatible traditional “antique” paving in keeping with their aesthetic. Tanners Mill decorative concrete paving slabs have been specifically designed to offer an authentic reproduction of fine antique paving flags from a bygone era.

York Flagstones Colouring

With its grey/green colouring and realistic lightly riven surface for a classic look, this range emulates the characteristics of the York flagstones that were being produced in Victorian times. The distinctive worn antique appearance and shades complement many period properties and are perfect for use in any traditional British garden setting.

Weathered Look & Feel

Finding aged and weathered flagstone paving can be time-consuming and very costly. Tanners Mill flagstones provide you with exactly what you are looking for - with the right colouring, weathering and visual characteristics of well-worn and aged antique paving. This predictability and specificity in the aesthetic properties mean your project is going to save an awful lot of time and money getting what you know will work.

Tanners Mill paving has tapered and rounded edges, emulating antique paving. It has a simulated smoothed slightly riven and pitted finish to capture the aesthetic of ageing and weathering.

Sourcing Antique Flagstones

Reclaimed flagstones can, and often do, look spot on. But, if you don’t have enough of them, or they are from multiple sources and don’t quite match, you could run into difficulties. This is exactly the sort of project Tanners Mill was designed to solve. Its consistent and scaleable look and feel (in the volumes you might need), means days saved trying to source and match materials. As well as helping save money when sourcing materials, Tanners Mill is competitively priced too, so you’ll be saving on two counts by choosing them.

Natural Stone Means Natural Variation

Please remember that natural stone is a processed natural product and therefore has unique elements, features, patterns and tones within each stone slab. That is the essential characteristic that natural stone offers - the unique variation of each stone, and the natural charm and beauty that those individual slabs convey when laid together in your garden landscape. If you are looking for more uniformity and control of colours and patterns, then porcelain paving or concrete paving might be more what you want.

Laying Advice

To install and lay concrete patio paving slabs, you'll need to do the following steps:

  1. Measure up and mark out your patio - ensure you calculate both 1) area in square metres (m2)  and 2) the fall (slope) required for drainage.
  2. Dig out the patio area to create the substrate (220 -230 mm depth).
  3. Lay the sub-base of MOT Type-1 hardcore (compacted & 150 mm depth).
  4. Ensure you mix and blend the various paving packs to ensure the patio has a blended look, as packs can
  5. Coat the slabs' underside with priming slurry to improve their bond and help prevent moisture transfer. As concrete is porous, priming slurry will help protect the slabs from moisture transfer and capillary action from beneath the slabs.
  6. Trowel-in and lay a bedding course of mortar mix (50 mm depth) immediately prior to laying each slab.
  7. Lay the paving slabs on to the mortar bed and tamp down. Ensure you leave the desired joint spacing between the slabs and the slabs are “level” to the fall.
  8. Leave to set for 24 hours, so the mortar mix can cure enough for you to walk on the slabs.
  9. Fill the joints between the paving (pointing) with jointing compound.
  10. Optional: protect your paving by sealing the slabs with a purpose made sealant (natural finish or colour enhancing).

To calculate the areas of paving in square-metres (m2), the amount of sub-base hardcore or the amount of sand and cement you'll need for the mortar mix bedding course, please refer to our paving calculators.

Care & Maintenance

Concrete is a porous material and contains tiny capillaries and micro-fissures throughout its structure. Consequently, concrete paving is susceptible to water-based chemical erosion (acidic corrosion), physical erosion (frost action), and from staining from waterborne grime, salts and other mineral and particulate deposits. Therefore, as the UK has high winter humidity (generally 80-90%) and damp conditions are the norm, we recommend that you help protect and elongate the life of your paving by sealing the slabs against the water/damp based issues. Our impregnating sealers are designed to enter the capillaries and micro-fissures in the slabs, blocking those spaces to prevent water entering the paving.

  1. Natural finish sealer
  2. Colour enhancing sealer

In addition to sealing the slabs, we recommend ensuring you brush away leaves, dirt and other detritus regularly, especially in the autumn and winter when leaves, twigs, seeds and other windfall materials are likely to fall on your patio. If left on your paving, especially if damp, and worse still, allowed to rot down and become mulch-like, your paving will almost certainly acquire brown stains from the release of tannins from the windfall materials (think a used tea bag left on a kitchen counter for a model of what will happen).

As well as brushing off dirt and windfall materials, give your patio a hose down with water every so often. Use a low-pressure hose or keep any jet-wash far enough away from the slabs to ensure you don't damage them with the high-pressure water jet. For more stubborn stains and the build-up of grime, we recommend using a specialist non-acidic patio cleaner.
