Block paving cleaning, resand & sealing

How much does it cost to clean, resand & seal a block paved driveway in 2021?

According to Checkatrade the average price is £10.50 per square metre (+ VAT if applicable).

The Gleam Team price is only £7 per sqm up to 50sqm and £5 per sqm for larger areas in excess of 50sqm

For example, a 70 sqm driveway would cost on average £735 + VAT, we would charge a maximum price of £450 (50 x £7 + 20 x £5) and NO VAT.

Is it really necessary to resand block pavers?

The simple answer is, YES it is. Kiln dried sand is used as jointing sand between block and brick paving. The sand creates interlock between the blocks and helps hold them together and spread the weight of vehicles driving over them or parking on top.

Without the friction created by the sand the weight of cars using the driveway would be concentrated onto individual blocks causing them to break or work loose. When block pavers become loosened it also affects adjacent blocks and has a knock-on effect that can affect the strength and function of the driveway as more blocks become loose across the structure. Block pavng sand is an integral feature of the construction and effectiveness of a driveway.

Applying a sealant then helps stabilise, or harden, the sand to hold it in place and stop it being washed away by rain or weathering. Hardened sand also helps inhibit weeds from growing into soft sand.

Block paving repairs

We can carry out minor repairs such as sunken blocks that lead to puddles developing after heavy rain. We can take up the blocks around the dip and re-lay a fresh course of bedding material. This is then compacted and levelled and the blocks are replaced. The block paving refurbishment post discusses this in more detail.

How do you refurbish block paving in Kent?

  • sweep paving with a stiff brush to remove litter and other material
  • to reduce the mess and avoid waterlogging bedding material we often
  • remove the worst of the weeds by hand with a block paving brush
  • spray the blocks with specialist chemical to kill / remove black spots
  • chemical will also remove white lichen & black algae/ moss etc
  • after chemical has taken effect pressure wash pavers
  • thoroughly clean block paving removing all lichen, algae, dirt & weeds
  • deal with any other stains that become apparent e.g. oil stains
  • treat stained blocks with the appropriate degreaser / product
  • carry out any necessary repairs

Repairs to sinking block pavers:

  • Take up the blocks around problem areas, remove and replace the existing bedding sand with a fresh course of new material.
  • level off the new layer with a trowell and / or plastering float and check with spirit level
  • clean all the blocks around their sides and scrape off any bits of sand to ensure a close and tight fit
  • replace the blocks in their correct position and use a rubber headed mallet to on the tops and sides to compact them tightly
  • when blocks and bedding sand is dry add fresh kiln dried sand between joints and apply quality sealer to stablise the sand

Patio Repointing

We believe in offering the most comprehensive patio renovation service and that includes repointing stone and concrete slab mortar joints. If you have isolated areas of paving where the mortar is missing or cracked and damaged we can replace those particular areas and try to ensure as close a colour match as possible to the existing mortar. We can also rake out larger areas and replace all the joints with fresh sweep-in jonting compound.

Pattern imprinted concrete cleaning & sealing

Pattern imprinted concrete (PIC) is also known as decorative concrete and stamped concrete. It involves wet concrete being patterned and textured to look like bricks, stone, tiles and other materials and colour is also added to the appearance for a more attractive finish. Decorative concrete utilises the strength and effectiveness of concrete as a building material whilst enhancing its visual appeal for use in a residential setting. It can be used for building a driceway, patio, path or other areas that need paving.

How do you clean imprinted concrete?

Pressure washing is usually regarded as the automatic choice for cleaning PIC, and it is an option when used with care. However, Gleam Team also specialse in low pressure soft washing as an alternative cleaning method for PIC that reduces the risk of damaging a delicate surface. There are many highly effective concrete cleaning products and degreasers available and when combined with a soft wash can clean and brighten imprinted concrete and remove oil, algae and other unsightly staining.

Should imprinted concrete be sealed?

Yes, all manufacturers and experts agree that stamped concrete should be sealed to maintain and enhance its appearance as it will otherwise fade over time. Sealer also helps prevent stains, reduce dust and dirt, prevent abrasion marks such as car tyres and prevent water being absorbed into the concrete. When water freezes its expands by approximately 9% and trapped water goes through afreeze and thaw process causing it to expand and contract, which in turncan lead to cracks in the cconcrete that will get worse during future freeze and thaw cycles. PIC sealer helps stop this problem by waterproofing the surface.

How often should stamped concrete be sealed?

Individual cases will vary but the generally accepted timeframe for resealing PIC is every 2 – 5 years.

Types of driveway & patio sealer

Paving sealers come in a range of finishes such as clear / invisible, wet look and gloss and some sealers are multi purpose and can be used on various paving types while others are designed specifically for a certain material e.g. natural stone / Indian Sandstone.

There are also block paving sealers made specifically for block pavers and jointing sand stablisation. Put another way, they are intended to harden the sand used to fill paving joints and bind individual grains of sand together to stop it being washed away by rain and weathering. By hardening the sand the sealer also helps inhibit weed growth as weeds can’t grow into the hard sand. Block paving sealers are also available in a range of finshes depending on your preference.

Indian Sandstone sealer & colour enhancer

There are a range of specialist sealers developed for natural stone and usually available in a clear or gloss finish. Another variety are marketed as ‘colour enhancers’ but this term can mean different things to different people. In practice, we have found colour enhancers have the effect of darkening stone and do little to enhance it. We also believe that after sandstone has been professionally cleaned and restored the natural beauty of the stone shines through and doesn’t need a sealer that changes its appearance. Specialist stone sealer can be significantly more expensive than more general purpose sealers but they are also designed to last longer – up to 5 years.

Many of the leading sealant manufacturers sell small sample tins which can be used on a discreet area of paving to test the results and help customers make a more informed choice.

Black limestone cleaning and sealing

We can safely and effectively clean limestone paving and restore fading black limestone or transform standard grey / blue stone into a very stylish, long lastng black limestone. This is without doubt one of the most visually stunning patio paving styles when done correctly with top end materials.
