KANTAFLEXTM PVC Water Stops are profiles based on specially formulated plasticized PVC composition. PVC Water Stopper is used in concrete masonry construction of hydraulic structures to safeguard from hydrostatic pressure and water seepage. Water Stopper also withstands expansion and contraction of joints as well takes care of any deflection and displacement arising due to change in temperature or settlement of foundation eliminating dangers of cracks since these is engineered as water tight seals in poured concrete structures. After being embedded in concrete, PVC water stops fill up the joints to form a continuous watertight diaphragm that prevents the passage of fluid. Most popular way of the placement of the water stop seal is tied to the steel frame works or small eyelet by means of small wires, certain metal clamps made to grip the water stop seal to keep it in proper position. The water stop must be designed and installed properly to accommodate joint expansions, contraction and lateral & transverse movements. In addition to these considerations, the water stop must be compatible with the concrete system and the liquids and chemicals to be contained or controlled. The basic kind of water stops, suggested normally for use in construction joints where movement is not expected, is the basic type of flat ribbed waterstop, However the ribbed type with center bulb is used in expansion joints where movement is likely to occur.   KANTAFLEXTM PVC Water Stops have good ageing properties leading to longer life, have high mechanical strength, chemical resistance, corrosion resistance, excellent weather resistance, lower water absorption, non hazardous and flame retardant, good shock bearing capacities against earth quakes, floods, heavy turbine vibrations, allows safe passage of seepage water, easy to weld and install. KANTAFLEXTM PVC Water Stops maintains its premier position of the preferred industry supplier by offering customized products meeting specific needs of our customer. We offer a wide variety of PVC waterstop in rolls, in width up to 300 mm and thickness of 4 to 12 mm. We also welcome any special or customized design from the end user.

KANTAFLEXTM PVC Form liners for Concrete are extruded profiles are used to enhance the concrete appearance. We provide a very wide range of concrete form liners for the construction industry. We offer these liners in width upto 300 mm and in continuous lengths. The customers are welcome to choose from our standard design / patterns or may suggest their own designs. With our own mold design and manufacturing facility, we offer an unmatched design flexibility and can produce any linear design. Our Form Liners are designed to provide minimum leakage, easy and fast installation, thus saving on the material and labor costs. These factors coupled with the fact that our liners can be multi-used, makes our product an unmatched offering in its category to the construction industry.    Care should be taken not to expose these liners to intense heat or cold as the extreme temperatures can deteriorate form liners. Application of good quality release agent, after checking the suitability of the same, is also suggested for longer life and multiple use of the form liners. Form Liners must be cleaned after every use. It is also suggested that these liners must be removed as soon as possible, preferably within twenty four hours of concrete placement as the heat of concrete hydration may damage the liners or may even cause sticking. Prolonged contact with foam liners may also cause the concrete to darken. Ribbed Formwork needs particularly careful handling while stripping to avoid breaking the fins. Care should also be taken to strip at 90º angle. The extra care taken during the removal of form liners will help in saving the costs involved in repair of the concrete surface and / or replacement of damaged liners.

Kantaflex P.V.C. expansion joint shall be placed slightly below the road surface. Expansion filler joint (20 mm thick) shall be insertedin the gap of either side. Sealing compound shall be applied both top and bottom for perfect fitment.

Insulating Rubber Mats are especially designed to be used in front of switchboards and high voltage equipment. These long life mats are designed to protect operators from electrical shocks thus acting as a personal protection equipment. We offer a range of insulating mats for almost any application. We offer Insulating Rubber Mats for insulation up to 33,000 volts (33 KV) meeting the requirements of IS 15652:2006. We offer Class A (3.3 KV), Class B (11 KV), and Class C (33 KV) insulating rubber mats as per following specifications.

Copper expansion joint (2 mm thick) shall be placed slightly below the wearing coat. Compressible fiber (20 mm thick) shall protect the edges of the copper expansion joint. Filler Joint (20 mm thick) shall fill the gap upto the top level of the wearing coat. Sealing compound shall be applied both top and bottom for the perfect fitment.

Edge beam shall be placed in such a manner that the grooves are positioned properly. Steel structure and main reinforcement shall be anchored with proper welding. Alignment shall be checked for both steel structures,if required by using suitable device. Recess shall be filled with high quality of the concrete not less than M 35 grade. If any installation brackets were used,shall be removed after the concrete has cured. Kantaflex elastomeric strip seal shall be cut into the required length and inserted between the beams by using the proper device and to be ensured that the bulb of the seal is getting into the steel grooves of the both edge beams. When the recess concrete has become set, a sturdy ramp shall be placed over the joint to protect the exposed steel beams and the elastimeric seal from the traffic. Without carriageway surfacing, expansion joint shall not be exposed to traffic loading.

Steel structure are to be inserted as shown above in either sides, little lowered position. Top of the insert shall be at par with finished level of wearing coat to maintain the camber. Steel structure and main reinforcement bar shall be anchored with proper welding. If required spacer bar shalll be used for proper alignment of bolt and leveling of steel insert Steel structure are to be packed with proper mixture of concrete as same as deck casting.

KANTAFLEX TM Elastomeric Bridge Bearings are designed to transform the movement and rotation of bridge structure into elasticity and minimizes the secondary stress generated in bridge because of the layered rubber sheets reinforced by metal plates. These bearings are designed to accommodate vertical, longitudinal, horizontal and transverse loads movements and rotation of the superstructure caused by thermal effect, traffic loads, structural load, wind load, seismic load etc. These bearings effectively release the stress on the bridge and have excellent rotation in all the directions and movements. The inserted metal plates restrict the rubber expansion on the sides and improve the resistance to load on the bridge as the elasticity of rubber absorbs shock well and lengthens the natural period of stress. Another advantage is the robustness and corrosion free nature of these products, ease and convenience of installation, long service life and customized size to suit the bridge design.
