Product details

Stow Riven Concrete Paving

The Stow concrete paving range is designed to bring low-cost, attractive and durable utility paving slabs to homeowners for a range of garden applications such as paving bin areas, shed and greenhouse bases. They are available in two colours (grey and buff) and two size formats (600 x 600 mm and 450 x 450 mm).

Utility Paving

If you're after the ideal paving for a utility area (meaning that it is used less often and sees less footfall/traffic across it) then these slabs are the perfect solution. They are low-cost and specified to meet the needs of utility paving, offering versatile, aesthetically pleasing quality paving at a budget price.

Stone-Effect Finish Concrete Paving

Stow Riven Concrete Slabs are a budget utility-style concrete slab range designed to suit the homeowners looking to pave areas where less foot traffic is necessary.

The classic weathered appearance and natural stone looks of Stow Paving provides for a timeless aesthetic, taking its styling from the appearance of natural stone. The concrete slabs look like hewn stone and have subtle shallow riven surfaces that offer an ideal base for a variety of utility applications such as bin areas, shed and greenhouse bases etc.

Uniform Colour

Stow slabs will provide your paved area with a consistent look and feel that closely mimics riven natural stone, but additionally offers uniform colour and tonal variation. Because these slabs are manufactured rather than quarried, their aesthetics are factory-controlled - and so they provide precise and consistent colour and tonal control - meaning you get exactly the look and feel you were expecting.

This colour pigment uniformity and aesthetic control/predictability are the main performance advantages presented by concrete paving over natural stone paving.

Durable Concrete Paving

These slabs are manufactured using a hydraulic-press dry-cast method, meaning consequently that they possess greater strength and durability than alternative wet-cast decorative concrete slabs.

Laying Advice

This paving should be laid on a full bed of mortar (laying course) of approximately 50 mm depth, which in-turn should sit on a compacted sub-base of suitable material (MOT Type-1 hardcore) which should be at least 150 mm in depth.

The paving slabs should securely bonded to the laying course by adding a coat of priming slurry to the back of the slabs immediately prior to laying them. 

Pointing your patio couldn’t be any easier! Gone are the days of time-consuming traditional pointing with sand and cement. Paving Direct recommends using a brush in compound such as Pavestone Pointfix. This is a two-part jointing compound. One pack contains epoxy resin within the compound and the other epoxy hardener. Mixing and applying Pointfix is much cleaner and easier than traditional sand and cement mortar, as you simply just mix the contents within the tub and brush into the joints.

Pointfix is available to buy in two options. Either as a single tub with 7m² coverage, or as a cost-saving triple-contractor pack with 21m² coverage.

Concrete Curing & Installation

Concrete flags are not fully cured when you install them. The curing process can take many years to complete. Therefore, there are a few precautionary steps you need to take to ensure that differential curing (varying rates of curing) are avoided. Most of these step involve ensuring that water, moisture and damp are not adversely effecting the slabs.

  • Use a full bed of mortar on the laying course
  • Ensure that the bedding mortar of the laying course is not too wet to avoid excessive moisture transfer
  • Use either an SBR bond in the bedding mortar or priming slurry on the backs of the concrete flags to help avoid moisture transfer to the slabs from the bedding layer
  • Ensure the paving has sufficient drainage and an appropriate fall/gradient, so surface water can run off the paving to avoid standing water
  • Use an appropriate jointing compound that is waterproof to prevent water entering the joints of the paving.

By taking these steps, you can help avoid some of the potential causes of differential curing/weathering with concrete flags.

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 that any potential colour variation in manufactured batches are not discernable
  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 flags.
  6. Trowel-in and lay a bedding course of mortar mix (50 mm depth) immediately prior to laying each slab. Make sure this mix is not too wet to avoid moisture transfer to the flags.
  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 flags.
  9. Fill the joints between the paving with an epoxy based waterproof jointing compound. This will prevent water ingress between/under the concrete flags.
  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.
