POLYBLOK
Rising damp is a phenomenon
often encountered in several buildings especially at the ground or plinth
level. This happens unless there is a provision of an efficient damp proofing
course. These moist conditions not only mar the appearance of internal wall
finishes but also affects the health of the inmates.
The stoppage of the rising damp
can best be achieved by a barrier which can block the capillaries through which
water rises from the ground. POLYBLOK is an efficient product which can perform
this function.
POLYBLOK is a two component
product which has to be introduced into pre-drilled holes. The two components
should not be mixed, but poured individually into the holes after an interval
of time. In the capillaries they react to form a gel which functions, as a
barrier or block, thus preventing any further rise in water & dampness and
protecting the structure.
The walls soon dry out and
remain dry, they can then rendered suitably. The complex process of reaction of
the two components results in an insoluble gel, which is innocuous.
POLYBLOK two pack system
provides a right material for solving nagging dampness problems especially in
superstructure. Ground water rises in brick & block walls through wicking
action of the capillary system present. This comes out at certain locations and
appears over the plaster as dampness & on drying as deposits of salts which
have migrated from the soil. At times and with age peeling of plaster due to
premature degradation is also seen.
POLYBLOK is eminently suited to
solve the above problem. It is easy to use.
Uses
POLYBLOK is suitable wherever
damp patches appear on walls above plinth or floor in Heritage structures, old buildings, Buildings located in low lands
etc. due to rise of water through capillaries.
Instruction for use
The barrier of POLYBLOK has to
be at the lowest possible parts of the walls. Ideally it should be located at
the normal location of DPC is or just below it. Hole are to be drilled in the
wall. Adopt (see sketch) spacing of 25 or 30 cm horizontally and 20 cm
vertically, zig-zag fashion. The holes are to be inclined (1.2 V.H or 300)
to the maximum depth possible say 80% of the wall thicknesss, 20mm or smaller
(12mm) holes are to be made.
POLYBLOK (Part I) should then
be gradually filled into the holes one by one. This should be allowed to soak
into the brickwork. The filling should continue till absorption is neglible,
which can noticed through constant level.
The facilitate pouring into
holes use suitable funnel fitted with a tube or spotted container. After about
half an hour repeat the operation with (part 2) of POLYBLOK.
The operation may be repeated
next day in case it is felt the dampness is very severe.
The holes thereafter should be
suitably sealed.
The old weak & deteriorated
& finishes should be removed, the original dampness allowed to dry for two
weeks to dry out. Finally the plaster & finish redone.
