How does a Granitgard stone barrier work?
Granitgard particles principally work in three ways.
They are too hard for termites to chew, they are
generally too big for termites to move, they sit closely
together so that termites cannot squeeze through.
How long
will my Granitgard physical termite barrier system remain
effective?
Granitgard stone
is already many millions of years old, so it is unlikely to fail before
the rest of the building. Granitgard strip shielding and Blockaid
have been tested & assessed by others as meeting a 50 year durability
requirement.
Can I
install it myself?
In a word, no.
Termites only need a little more than a one millimetre gap to get
in. In order to maintain quality and offer an industry-leading
warranty, only a small army of 500+ specially trained and
licencedtradespeople are permitted to install Granitgard
products.
How often
should my home be inspected?
Australian Standards stipulate a 'competent' inspection at
least once a year and more often in high risk areas. Regular
inspection by appropriate professionals is always recommended but you can
and should keep an eye on things in between. See your Granitgard
Maintenance Instructions* and Treatment
Certificate* for details of inspection requirements to
maintain warranty cover.
How does
Blockaid work?
Blockaid
blocks termites because the bitumen component provides excellent
durability and adhesion, the rubberised polymers provide flexibility and
strength, and, for termites,
the plant extracts are
unpalatable. Blockaid cures to form a solid but flexible
mass that stays strongly bound to common building
substrates.
How much
does Granitgard cost?
Pricing depends on construction type and location, but is
generally not more than 1% of the cost of the home. Over the years,
Granitgard becomes much less costly than chemical systems. Granitgard
installation is not franchised and in many areas, Installer companies will
compete for your business.
How often
will my system need maintenance?
Granitgard barriers are intended to last the economic life
of a building. Unless disturbed by some outside force, a Granitgard
barrier system should not require any maintenance beyond the simple steps
detailed in the Maintenance Instructions*.
Consult your licenced Installer before
beginning any building works or repairs that might damage or conceal the
barriers.
