Description
The K A Tanking Slurry
waterproofing system provides a solution to water leakage,
ingress or seepage in concrete structures
or any cementitious substrate. The formation and
development of insoluble crystals into water bearing
capillaries and fissures effectively blocks the further
passage of water and ensures permanent water tightness for
the life of the structure.
The KA system is designed to
function against water penetration in various conditions. KA
tanking slurry is supplied as a powder and when mixed with
water is applied directly to concrete, blockwork masonry or
cement renders in areas where general waterproofing is
required. KA Tanking slurry is used in conjunction with ka
water plug for instant leak plugging.
Areas of
Use
KA
Tanking slurry can be applied to new or old structurally
sound surfaces. It can be applied. Either to the negative or
the positive side and will negate dampness in ground water
permeation even under hydrostatic pressure. KA Tanking
slurry can be used for the following applications.
-
Retaining walls and
columns in reservoirs
-
Swimming pools prior to
tilling or painting
-
Concrete drinking water
teams
-
Water treatments and
sewerage plants
-
Foundation slabs
-
Underground cellars,
basement car parks, garages, etc
-
Pre-stressed and pre-cast
concrete units
-
Tunnels, silos, irrigation
channels
-
Bathrooms, kitchens, etc
-
Sand – cement render
-
Lift shafts
-
Vehicle maintenance pits
Advantages
-
Provides excellent
waterproofing properties by becoming an integral part of
the structure to which it is applied.
-
Non toxic
-
Non tainting
-
Dual crystalline and
surface action
-
Allows the substrate to
breath
-
The migratory crystalline
action is reactivated should future water contact occur
-
KA Tanking slurry becomes
integral to the substrate, thus eliminating potential
wear, de-lamination or peeling
Preparation
As with
most coating treatments, surface preparation is critical and
although this can be time consuming it is essential that it
be carried out thoroughly. KA Tanking slurry is only fully
effective if the capillaries in the brickwork, concrete or
mortar are sufficiently absorbent to allow penetration of
the crystalline chemicals. All surfaces should be clean and
free of paint systems, oil, loose dust, shutter treatments,
curing compounds, surface hardeners and other contaminants.
Surface preparation can be best carried out using high
pressure water jetting, grit blasting or mechanical
scrabbling. Water jetting has the advantage that complete
saturation of the substrate is achieved but lack of drainage
facilities may in some cases preclude its use. Large cracks
and other defects can be repaired using a 3:1 sand : cement
mortar gauged with SBR. Repaired areas can be coated with KA
Tanking slurry after 24 hours, but large areas of new
brickwork, poured concrete or cement renders should be
allowed to cure for 3 days before application of KA Tanking
slurry is considered |
