What
is Waterproofing?
Waterproofing is making a building or structure
waterproof or water-resistant. In the building industry of Goa, every freshly constructed
edifice needs waterproofing as concrete by itself will not be sealed or watertight
on its own but concrete can be easily waterproofed with chemical solutions.
The standard methods of waterproofing in Goa
involve 'membranes'. This relies on the use of one or more coatings of membrane
(available in various materials: e.g., bitumen, silicate, PVC, EPDM etc.) that
act as an blockade & barricade between the water and the house or shop or
office structure, thus avoiding the means of admission of water.
New membrane supplies developed by the
Waterproofing industry in Goa seek to overcome flaws and faults in older
methods like PVC and HDPE. Generally, new waterproofing know-how in waterproof
membranes depends on polymer-based ingredients that are immensely adhesive to produce
a joined barrier around the external side of any constructed structure.
What
is Damp Waterproofing?
Waterproofing is the management of a construction
surface to stop the passageway or channel of liquid water in the presence of
hydrostatic pressure.
Damp-proofing is the management of a surface
to delay the absorption of dampness and wetness in the absence of hydrostatic
pressure.
Many times edifices in Goa are waterproofed on
the exterior and damp-proofed on the inside to give the complete building
structure a wrapping of protection and defense from the rains.
Water proofing solutions by Parkar Construction of Ponda installs a waterproofing method which stops the full passage of liquefied rain water or other water in the presence of hydro static pressure.
Essential Physical repairs or protection as
needed is carried out. An operational and unblocked drainage system has to be
working to reduce hydrostatic pressure.
Water ingression (entering of water) can
happen from the roof, from sideways (the part of the structure facing the west
or towards the sea) and also from the ground above (ground level water table).
Water ingress in structures in Goa can happen
from seepage through joints or cracks that are not filled in time, permeation,
wick action, salts in drainage, under structure permeation.
Rain water of Goa pierces concrete buildings
through openings at large cavities and small holes and flaws in the building,
hairline cracks and small fissures in the walls, at weak joints, and in
Concrete structures, Capillary actions sucks water into pores, Hydrostatic pressure
forces water into pores.
