Driveway Cleaning
Driveways laid in block paving are very popular in the West Midlands.
When first laid in either the traditional herringbone pattern or the contemporary tumbled blocks, this can be the best looking driveway surface, giving the most appearance-enhancing effect to your
home.
If only they stayed looking that way! The joints between the blocks are filled with sand which tend to attract moss
and weed growth and the blocks themselves are quite porous, meaning they retain water which can make them attractive to algae and lichen which are seen as spots on the surface.
Envirotech offer a complete cleaning, sanding and sealing process which can renovate even very
tired-looking block paving and crucially, take big steps to stop it looking like that in the future.
Our procedure to renovate block paving is usually:
- Pre-treat with weedkiller and leave for several days
- Pressure wash thoroughly, taking care to get as much general dirt and sand out of the joints as possible to a depth of 20-25mm
- Leave to dry for several days, then sweep new kiln-dried sand into the joints
Seal with Adseal Block Paving Sealer, which sets the jointing sand solid, meaning moss or weed growth can't take
hold. This product also beautifies the surface, leaving it with a quality sheen and protects against oil stains or any type of staining.
