Conventional ways of controlling the
dangers of dust sometimes create greater problems than the
dust itself. Use of the wrong dust suppressants has caused
lingering environmental and health concerns. Increasingly,
legislators are outlawing dust suppressants that are found to
be dangerous to humans and our natural environment.
Water often becomes the dust
suppressant of choice. Unfortunately, it is not always
available. And water provides only a short-term remedy that is
labour-intensive and requires costly multiple
applications.
Wetless is as it's name implies, wetter than
water, ten times wetter than water. Wetless aids immensely in
compaction by virtue of the way in which it controls
hydration, thereby, decreasing water surface tension and
promoting a uniform transmission of moisture throughout the
soil.
The principal object of Wetless is to penetrate
the soil more rapidly allowing a more through mix and an even
distribution of moisture using far less water. Wetless
hydrates far slower, seven to ten times slower than water
alone so is ideal for dry hot days and even dry hot and windy
days when the truck just can't keep up.
Secondly, the surfactant in Wetless is
specifically formulated to be ten times wetter than water
alone to control hydration, so that the soil wets out more
rapidly and stays at the desired moisture content for a longer
workable time.
Wetless saves on haulage both in
distance and time, all the time the truck is away the soil is
hydrating faster than the truck can travel, pump and return.
Some soils using just water need to be left over night for
correct penetration, with Wetless you can use the soil right
away.
The proportions of WETLESS required to bring a
given soil or gravel to a workable consistency varies with the
ratio of sand and clay in the soil. A soil high in clay
content absorbs a greater amount of moisture before it reaches
plastic state than soil high in sand content. Other factors are the
soil moisture content on the day and the ambient temperature
coupled to the degree of wind, as all of these factors affect
the rate of hydration.

WARNING
> Always add Wetless to a full truck of water, never first.
No agitation or mixing is required.
It is not claimed that the use of Wetless will
increase the strength of a pavement when it has dried back but
compaction will definitely be aided.
