One of the leading causes of waterproof deck system failures is the movement of underlying substrates (plywood) that cause too much stress on the membranes resulting in a failure of the system. Waterproofing of decks and balconies is a complex compliment of many complimentary elements. These include the waterproofing membrane used, adequate slope/drainage, proper flashing details, and proper construction materials. The penetrations through a building envelope need to be built in a way such that water does not enter the building, such as using flashing and special fittings for pipes, vents, wires, etc.

Over the past two decades, the construction industry has had technological advances in waterproofing materials, including integral waterproofing systems as well as more advanced membrane materials. Integral systems within the matrix of a concrete structure, giving the concrete itself a waterproof quality. There are two main types of integral waterproofing systems: the hydrophilic and the hydrophobic systems. A hydrophilic system typically uses a crystallization technology that replaces the water in the concrete with insoluble crystals. Various brands available in the market claim similar properties, but not all can react with a wide range of cement hydration by-products and thus require caution. Hydrophobic systems use fatty acids to block pores within the concrete, preventing water passage.

Our specialized areas in waterproofing are:

WATERPROOFING

Areas of application:

• Reservoirs
• Sewage and Water Treatment Plants
• Underground Vaults
• Secondary Containment Structures
• Foundations
• Tunnels and Subway Systems
• Swimming Pools
• Parking Structures

Advantages:

• Resists extreme hydrostatic pressure
• Becomes an integral part of the substrate
• Can seal hairline cracks up to 0.4 mm
• Allows concrete to breathe
• Highly resistant to aggressive chemicals
• Non-toxic
• Does not require a dry surface
• Cannot puncture, tear or come apart at the seams
• No costly surface priming or leveling prior to application
• Does not require sealing, lapping and finishing of seams at corners, edges or between membranes
• Can be applied to the positive or the negative side of the concrete surface
• Does not require protection during backfilling or during placement of steel, wire mesh or other materials
• Less costly to apply than most other methods
• Not subject to deterioration
• Permanent

CEMENTIITOUS WATERPROOFING

Two component product consisting of Part “A” waterproofing powder and Part “B” a blend of liquid acrylic latex copolymers. Both products part “A:’ and Part “B” are mixed at the job site and applied with a brush or trowel. During the membrane application a fiberglass is embedded within the wet cementitious mix.
Areas of application:

• As a waterproof coating for sea-water structures.
• As a waterproof coating for concrete slabs, roofs, balconies kitchens and bathrooms under tiling floors.
• As a coating for sewage treatment plants.
• As a waterproof lining for water retaining structures/ swimming pools.

Advantages :

• Easy to use: Easily brushable or trowel applied product.
• Constant quality: Always fresh locally, manufactured factory quality controlled product.
• Durability: This latest technology combination of special raw materials deliver superior durability under our local climatic exposure.
• Adhesion: Excellent bond strength of porous and nonporous surfaces.
• Flexibility: The Part “B” component is specially blended copolymer of acrylic latex which improves adhesion flexibility and waterproofing characteristics.
• Anti-carbonation :A membrane of 1 to 1.5mm thickness provides an excellent shield against the penetration of carbon dioxide and chloride ions.
• Waterproofing: Excellent even under pressure.
• Vapour Permeability: A fully cured membrane of 1 to 3mm thickness is vapour permeable and allows, the substance to breath.

LIQUID APLLIED POLYURETHANE WATERPROOFING

It is a liquid-applied, solvent-free, hard elastic, cold applied and cold curing, two component polyurethane membrane used for long-lasting waterproofing and protection. Cures by reaction (cross linking) of the two components.

Areas of application:

• Waterproofing of Drinking Water Supply Channels.
• Waterproofing of Drinking Water Pipes.
• Waterproofing of Drinking Water Tanks and Reservoirs.
Odorless waterproofing of Wet Areas (under-tile) in Bathrooms, Swimming Pools, Kitchens, etc. Used for waterproofing of surfaces in direct contact with potable (drinking) water. Used for waterproofing of not well-ventilated, Wet Rooms and Wet Areas (bathrooms, kitchens, etc) applied under the tiles, when a odorless, solvent-free coating is required.

Advantages:

• Certified for safe use in potable (drinking) water reservoirs.
• When applied forms seamless membrane without joints or leak possibilities.
• Resistant to water and frost.
• Maintains its mechanical properties over a temperature span of -30o C to +90o C.
• Remains elastic even at low (frost) temperature.
• Full surface adherence.
• The waterproofed surface can be walked on.
