Urban Surface Protection
A
revolutionary new pre-treatment for paving to protect against
surface contamination.Reducing costs of cleaning and
maintenance.
One of the biggest problems
experienced by specifiers of high quality landscaping materials is
to maintain the original appearance over a long period of time.
This problem is particularly prevalent in areas subject to heavy
pedestrian traffic and is the result of a number of
factors.
Urban Surface Protection provides many
solutions
Unlike other surface protectors, USP is
preapplied to the paving before it is delivered and laid. Whilst an
element of cleansing may still be required during the life of the
paving, the frequency and severity will be significantly reduced.
USP will substantially lower maintenance costs. The sealant gives
self cleansing properties, meaning that heavy rainfall can wash
away most deposits. Chewing gum will not adhere over a long period
so paving will only have small build ups rather than increasing
growth.
Features and benefits
Why use USP?
Cost savings – cleaning our
city centres, including chewing gum removal¹, can cost up to £23.40
per sq metre per year. Charcon paving with pre-applied USP reduces
maintenance costs to just £4.20 per sq metre per year. With this in
mind,
based on a city centre the same size as
Liverpool², local authorities can save in the region of £576,000
per year³ with Charcon.
1. 10p per piece, average of 15 pieces per
square metre
2. 30,000 sq metres
3. Based on cutting down cleaning
frequency from six to three
Reduced cleaning frequencies
– surface soiling cannot penetrate the product, therefore is washed
off during rainfall.
Chewing gum - initially binds
to the surface so as not to transfer onto shoes and then into
public buildings. As the chewing gum dries, it will remove easily
with the use of street sweepers or low-powered washers.
Evidence has shown that two men clean 30 m2 of
chewing gum in four hours, however, with Charcon USP pre-applied,
two men can clean 480 m2 in this time.
Reduced cleaning intensity -
the pressure and quantity of water required, regardless of water
temperature, all result in cost savings. The reduced pressure also
eliminates the removal of sand and mortar between block paving,
resulting in less trip claims and the requirement to
re-sand/mortar.
Anti slip properties - as the
product is not simply a coating, but an impregnator, the topography
of the surface remains unchanged.
Ice conditions - the effect
of water freezing on the surface, due to the beading effect,
actually assists in providing grip. The application of salt does
not affect the product.
No waste – by pre-applying
USP to Charcon paving within the manufacturing process, any surplus
liquid is collected and re-used, resulting in no wastage.
Problems and solutions
Problem
Day to day, surface contamination presents an
ongoing problem to local authorities who face huge cleaning and
maintenance costs. Staining is an increasing issue with such
problems as fast food litter, up 17% in the last four years. Other
contaminants such as bird droppings, moss and chewing gum, which
cost the UK in the region of £150 million per annum to remove, are
difficult and expensive to treat.
Solution
Charcon Urban Surface Protection (USP) is
pre-applied to the paving, preventing the adhesion of contaminants
such as chewing gum, bird droppings and moss, as well as
eliminating staining.
How it works
Charcon USP is a chemically inert,
environmentally friendly water based fluoro polymer. Its mode of
action when applied, distributes and binds fluorine molecules to
the topography of the treated surface. The fluorine molecules
through their chemical composition, give the treated surface
non-stick properties.

Urban Surface Protection product range
Unlike most surface protection products,
Charcon USP is preapplied to many of Charcon’s paving range,
eliminating the need to pre-clean laid areas of paving in order to
apply the surface protection.
