Technology |
Crystalline
waterproofing technology. End products with crystalline
structure penetrate the pores and capillary tracts
of the concrete mass preventing the intrusion of water
and aggresive chemicals from any direction |
Acts
only as a barrier on the top surface. |

Sealing
capacity |
Can seal
hairline cracks upto 0.4mm dia. |
Depends
on the solid content and flexibility of the polymer
and the filler powder used. |

Self-healing
capacity |
PRESENT..
At any later stage ,when gets in contact with water
, the crystalline process initiates and seals the cause
for leakage. |
Not Present.
Even if accidental damage to the coating occurs, it
leads to failure resulting in huge investments for repairs.
|
| 9. |
Neccessity
of protection during back filling |
Not necessary
resulting in considerable reduction of material cost,labour
cost and above all TIME. |
Necessary.To
protect the thin film coating, plastering has to be
done resulting in additional costs for materials and
labour and time. |
| 10. |
Application
user friendliness |
Very
much user friendly. Can be brush coated on the negative
(or) the positive side (water pressure) ,works head
on water pressure and also on the green and old concrete. |
Cumbersome.
Coating has to be done only on the positive side |
| 11. |
Necessity
of additional materials |
Does
not require sealing, rapping and finishing of seams
at corners, edges (or) between membranes, resulting
the reduction of considerable additonal cost for waterproofing. |
Sealing,
lapping and finishing of seams have to be carried out
with other sealants for effective waterproofing there
by the total cost of waterproofing process would increase. |
| 12. |
Hydrostatic
pressure withstanding capacity |
< 1.2
M Pa ( the maximum limit of the testing apparatus) |
Depends
on the thickness and quality of the coating |
| 13. |
Action
on aggressive chemicals |
Not affected
by wide range of aggressive chemicals, where pH range
is between 3.0 and 11.0 constant contact.And 2.0 to
12.0 peridodic contact and also protects the reinforcing
steel from the rust accelerating electrolyte. |
Not recommended
for areas with high chloride and sulfate content. |
| 14. |
Application |
Carried
out by the technical team of SUPERSHIELD manufacturers
ensuring strict quality control in every phase to
render complete solution for the project |
As
a general practices application part is handled by
applicators whose technical proficiency and quality
control supervision may not be to the required high
standards |
| 15. |
Warranty |
Manufacturers
grauntee is provided and the whole resposibility is
undertaken. |
Only
applicators guarantee will be provided and incase
of disputes, passing the responsibility to the manufacturers
may result in not getting the complete solution. |
