What if any object falls on Endura Industrial Tiles ? Will the tile break ?

Endura Industiral tiles can withstand normal impact. They have been tested in automobiles garages where various implements and equipment often keep falling with no significant damage to tiles. However, the tiles are not unbreakable and hence the extent of damage, if any, would depend on the weight and shape and height of fall of the falling object. We therefore recommend a gap of few mm between tiles for easy maintenance or replacement, in the event of any damage.

What are the advantage of Endura Industrial Tiles over cement concrete tiles and Epoxy floors over a long term ?

Cement and Cement concrete tiles tend to pit that form pot holes on usage. In epoxy floors, there is a tendency to develop micro cracks which then tend to peel-off the floor. In both these cases it is difficult to repair the floor. When Endura Industrial floors are installed with proper spacing and grouting, they can be easily repaired by replacing the damaged tiles.

Do Endura Industrial Tiles stain easily ?

Endura Industrial is a vitrified tile with a very low water absorption. It is highly stain resistant as compared to most natural stones. The application of special over-spray helps seal any residual micro porosity and enhances the stain resistance of the tile.

Are Endura Industrial tiles good for using above waterproofing surfaces? Do they help in waterproofing ?

Endura Industrial tiles are most suited for use over waterproofed terraces as they withstand all the weathering effects roofs are exposed to and insulate against expansion and contraction of the waterproofing layer below. Normally dust on the roof and movement of people leads to abrasion of the waterproofing layer. Endura tiles on a waterproofed roof helps protects this surface. Care should be taken to test the waterproofing layer prior to tiling and tile joints should be sealed properly with epoxy or any other water-proof grouting material.

Is Endura Industrial Tile available in various shapes ?

Endura Industrial tiles come in squares and rectangles. This make it convenient to cut and create any designs or pattern as desired at the time of laying. Cement concrete tiles are cast into shapes and these cannot be cut.

What is the best way to fix Endura Industrial Tiles ?

Endura Industrial tiles are best fixed using ARDEX ENDURA Tile Fixing Adhesive and the gap between the tiles can be filled with ARDEX ENDURA grouts. ARDEX ENDURA Tile Fixing Adhesives and Grouts are available in India and are most compatible with Endura tiles.

Are Endura Industrial tiles acid / alkali resistant ?

Endura Industrial tiles are resistant to all alkalis and all acid (in high concentration), except HF or their derivatives.

In what size and thicknesses are Endura Industrial tiles available ?

Endura Industrial tiles are available in the following sizes and thicknesses: 60x60 - 2cm, 60x60 - 1.5cm, 30x30 - 2cm, 30x30 - 1.5cm, 30x30 - 1.2cm, 20.4x20.4 - 1.5cm, 20.4x20.4 - 1.2cm, 20x10 - 1.5cm, 20x10 - 1.2cm.

Why are Anti static tiles required ?

Static charge is a constant source of problem in various industrial processes, in areas where highly sensitive electronic or computing equipments are in operation, and in many areas of industries where inflammable chemicals or explosives are being used. In such areas sparking resulting from build up of static charge can become a major fire hazard. The use of antistatic conductive and dissipative flooring products helps conduct the static charge away, thus eliminating the hazard.

Is the Anti-static effect on Endura tiles long lasting ?

The Antistatic ceramic tiles (dissipative & conductive variety) are produced by mixing fine semi-conducting oxide powders into the ceramic glaze. Firing of the glaze to a high temperature results in sintering and formation of a stable electrically conducting network of ions in solid solution. This electrically conducting network is fused on the tile, thus making the Antistatic effect permanent for the lifetime of the product.

How to Antistatic tiles help reduce fire hazards ?

Static electricity accumulates on the surface of any floor be it natural stone, ceramic tile or other flooring material. This static electricity is accumulated due to the friction between any two surfaces like shoes and the floor. Endura Anti-static tiles are manufactured using a specially formulated conducting glaze that carries the static electricity charge from the surface of the tile to ground thus eliminating the fire hazard.

Which are the application areas recommended for Endura Antistatic tiles ?

Recommended application areas for Endura Antistatic tiles are Server rooms, Computer Data Center rooms, PLC Panel rooms, PCB Manufacturing units, Laboratories handling sensitive equipment or chemicals, Petro chemical industries, Shell making factories, Ordnance factories and other Defence factories, Bulk Drug plants, Chemical and Fertilizer plants, etc.

What are the other advantages of using Endura Antistatic tiles ?

Apart form antistatic propety Endura Antistatic tiles are highly abrasion resistant, have superior chemical durability, very high mechanical strength and are stain-proof.

What are the advantages of Anti-static Endura tiles versus tiles versus Vinyl or Epoxy based Polymer tiles and conducting rubber based flooring products ?

What is the recommended procedure for installing Endura Antistatic tiles ?

Endura Antistatic tiles can be installed using conventional cement - sand mortar or using synthetic adhesives such as ARDEX Endura and maintaining a 0.3 cm to 0.5 cm joint that is about 0.6 cm to 0.8 cm deep. Rake open the joints and fix good quality copper wire into the joints. The joints would then need to be sealed with conducting epoxy grout, to allow for a sooth discharge of any accumulated static charge.

Why are special tiles required for swimming pools ?

Safety of the swimmer and spectator is an important criteria for the swimming pool design. The pool surface is used when the feet are wet and the feet soles are soft after soaking in water. This condition necessitates the tiles to be specially designed to suit barefoot usage since the skin is soft and can get hurt easily.

What benefits do Endura swimming pool tile offer ?

Endura offers the best designed tiles for covering all areas of the swimming pool. Anti-skid property that give good grip without hurting in dry and wet areas. Coloured pool tiles that show depth and pool edge tiles with safety markings as per international colour coding standard (FINA) Specially designed fitting tiles to cover all corners ensuring no sharp edges. The unique body and glaze composition have been specially designed factoring in the fact that the pool tiles would be continuously exposed to water.

Do the swimming pool tiles adhere to any international standard ?

Yes. These tiles are made as per the stringent standards laid down by ASA, FINA ( Federation Internationale de Natation Amateur) & European Standards.

What are the other applications of swimming pool tiles ?

Endura swimming pool tiles can be used to line water tanks in buildings. The water storage tank which are either underground or overhead can be lined in the inside with Endura tiles to keep the area clean. The surface will have less algae growth as the tiles are coated with a impervious glass surface, thus making it an ideal choice for water storage, including drinking water.

How is CladStone different from commonly used Wall tiles ?

Cladstone is used for exterior application which enhances the Aesthetics & also increases the life of the Cladded Structure. CladStone has been developed in a small size of 24 cm × 6 cm with 0.6 cm body, which makes it unique for exterior wall application. Numerous creative combinations can be worked out with this small sized tile. The vitrified body of Cladstone ensures non fading of colors, thermal & frost resistance & protection of walls from external elements.
