Block Paving Cleaning

We carry out block paving cleaning to -

  • Kill unsightly moss and algae
  • Clean the surface completely
  • Remove all oil stains

Moss and algae treatments are applied to the surface before any work is started so that we can effectively clean block paving and 'see' the extent of cleaning that is necessary. We can then start the full procedure.

This is firstly achieved by using 'dirt splitting' solutions to break the soiling from the surface of your block paving, getting into all the porous elements of the concrete or clay pavers.

This releases the dirt which rises to the surface and is suspended for removal by power washing the paving or by dispersing with hot power washing depending on the severity of dirt.

Conventional power washing will sometimes drive soiling further into the surface making it difficult to remove and therefore is best lifted out gently for easy removal.

The last stage of the block paving cleaning process is to remove any oil on your block paving which might have leaked from vehicles. When the paving is clean, any areas affected by oil stains will be apparent and easy to remove.

Block Paving Sealing

On completion of the block paving cleaning process it will sometimes be necessary to re-sand the joints which stabilises the block paving retaining the strength and stability of your drive.

Kiln dried sand which is a very fine granular type, is swept into any open joints until 'full'.

A sealant can then be applied by spray or roller in two separate stages with a check on the compactness of the sand, which can be added to if necessary.

The finish will depend on personal choice as to whether you prefer a dry natural look or an enhanced finish which slightly darkens the block paving to heighten the colour.

Concrete block paving and clay blocks require specific sealants to penetrate the different surface types.

A drying period of a few hours is needed before walking on, allowing a full day before driving vehicles over your newly sealed drive.

Block Paving Aftercare

The sealed and clean block paving will be resilient to soiling and staining, moss and algae attack and any oil stains, however, to further protect the surface we will supply additional treatments to maintain your block paving, keeping it in pristine condition for many years.

We will contact you periodically for feedback and of course offer additional treatments for other areas that require our specialist tlc.
