PAVING
FAILURE When
sand erodes from a paving joint it leads to a loss of interlock within the paver system, resulting
in chipping and spalling and ultimately paver destabilisation. The erosion of the sand filled
joints can be either natural or man made, brought about by such forces as: heavy traffic, pressure
washing, weed growth or rainwater over a slope or gradient .The surface of unsealed pavers are also
susceptible to contamination from oil and fuel, this often leads to unsightly staining which is
extremely difficult to rectify.
SEALANTS The majority of sealants sold on the market
today are acrylic based. Varyclean only use high quality polyurethane coatings on unsealed
surfaces. Polyurethane is relatively expensive compared to acrylic, but latest research has
indicated they have a life span of 10 years or more, whereas the cheaper acrylics, which
although roughly half the cost usually have to be re-sealed every 12-36 months. We can also
offer anti slip additives to our products and a variety of coloured tints if
required.
APPLICATION We recommend sealing a newly laid surface as soon as
possible in order to prevent erosion to the joints and further damage to the sub base. Varyclean
uses the latest sealing techniques and offer approved protective coatings to create a stable and
maintenance free surface for years to come.
