WATERPROOFING

constructive solutionsWater proofing

What is waterproofing The treatment of a surface or structure to prevent passage of water under hydrostatic

pressure

Water retaining structures: keeping water in Reservoirs and water tanks Waste water treatment plants Dams Secondary containment bund Swimming pools Sewers and pipelines, etc


What is waterproofing The treatment of a surface or structure to prevent passage of water under hydrostatic

pressure.

Waterproof facilities: keeping water out Basements,Terraces Parking garages Underground stations and subways Utility vaults Reservoirs and water tanks Marine structures Tunnels, etc.


Causes for leakage Concrete shrinks and develops micro cracks Joints detailing & treatments Poor quality of concrete Poor workmanship High water table Water retaining structures Structural problems


Why is it required??

Leakage results in Corrosion and spalling Life of the structure is reduced Loss of revenue Remedial measures are trial & error and very expensive


Waterproofing Areas

Bellow Ground, Basement – Footings/Raft, Grade Slab, R-Wall, Above Ground, Podium & Roof Slab-Architectural water feature & horticulture

Nitoproof 600 Liquid applied single component pith based PU elastomeric waterproofing membrane

Uses

The high elasticity, excellent bond and low water permeability of Nitoproof 600 make it ideal for a wide range of water/vapour proofing applications such as foundations, basements, tunnels, ground floors, suspended floors, car decks, roof terraces, balconies, patios, bridges, Precincts, inspection pits, water retaining structures (not potable water), sewage works, and inverted roofs. The excellent chemical resistance of Nitoproof 600 makes it particularly suitable for tanking applications in areas where aggressive ground water conditions prevail.

Liquid applied PU membrane


Features and benefit

Single component No mixing required

Cold Applied No heating required

One coat application No over coating delay time

Seamless No laps

Fully bonded Elimination of water tracking

Irreversible chemical Does not permit the melting of cure membrane at elevated temp.
