WeatherTek Penetrating Damp


When masonry gets wet, it gets cold and cold walls mean cold buildings as heat escapes much more readily. Protect your home from penetrating damp and increase the thermal efficiency of masonry with WeatherTek. WeatherTek is a colourless, breathable, water-repellent treatment for brick, concrete, and stone walls. Once WeatherTek has been applied it will permeate deeply into the masonry before curing to form a water-repellent barrier.

How does it work?

WeatherTek is based on carefully selected silanes and siloxanes which line the pores of the masonry to form a water-repellent silicone matrix. Because it works by lining the pores rather than blocking them, the masonry is allowed to breathe, and does not suffer from an increased risk of frost damage (spalling). Due to its novel formulation and deep penetration, WeatherTek is highly resistant to UV light and other forms of degradation, resulting in a life expectancy of 20-30 years.

WeatherTek Features

• Protection against penetrating damp
• Improving thermal resistance of masonry by keeping it dry (energy saving)
• Maintaining thermal properties of cavity wall insulation
• Improving flood resistance of masonry

Did you know?

Scientific studies have found that wet bricks transfer heat twice as quickly as dry bricks.

The Benefits of Using WeatherTek


Protection Against Rain Penetration

WeatherTek will protect against water penetrating through the pores of bricks, mortar and stone. It will provide protection against rain penetrating through cracks in the masonry smaller than 0.3mm.

Energy saving

By providing in-depth protection against moisture ingress, WeatherTek is able to save energy. Scientific tests demonstrate that energy savings of up to 29% are possible by improving thermal qualities through using WeatherTek. WeatherTek is a cost effective solution that you can have applied to your property to reduce the energy that is wasted through damp porous walls. WeatherTek cures damp bridging of the cavity following the installation of cavity wall insulation and ensures that the insulation performs to optimum levels, saving you money in heating and maintenance costs.
