PVC Waterstops for Water proofing of concrete joints

What are Water Stop Seals & How they are placed?

Typical PVC Water Stop Seal

PVC Water-Stops are extruded profiles manufactured using special Plastic compound that is resistant to ageing, chemicals, have high tensile strength, good elongation properties. They are very much helpful in keeping the concrete structure Watertight, thus by provide strength, stability & Life to Mega structures & Multi-storeyed Buildings.

Water Bars prevents Concrete Structure against any change in atmospheric temperature which cause contraction or extension of Concrete joints which can cause displacement of different concrete layers & could result in cracks in walls, also helps in retaining Structure in case of Geo-disturbances like earth quakes. These can cause leakage of Water from underground sources. WaterStop when places at the time of construction makes the joints watertight thus doesn't allow any seepage of Water.

Installation of Water Stoppers

Water-stopper are available in a variety of forms, which differ in width, thickness & design. their selection should be bases on the understanding of soil, climatic conditions, geographic conditions, under ground Water Label, salinity of water in the Area. an advice from a certified Architect or civil engineer is always recommended for this purpose.

For example. At places, sudden temperature change due to climatic conditions is more often, causes expansion & contraction of structure. At these places Dumbbell type Waterstops are recommended.

How Waterbar are installed:- Half part is embedded in concrete (up to central bulb) while the other half hanging outside which is also embedded on next turn with proper alignment.

Areas of Application:
Hydro projects, Dams, Canals, Swimming Pools, Road, Water tanks, Cooling Tower, Basements, Multi-storied buildings.

How to joints two ends of Water stops

Heat Jointing of PVC Water Stop

The the ends of PVC Water Stops are joints together to form a single watertight strip, this can be done by two ways-

1. The two ends are heated using plastic heater till both the ends get softer & slightly melted then force is applied at both ends, this enables both the ends joint together.
2. Two different Rolls are pasted together using synthetic Rubber Adhesive radially available in market.

PVC Waterstop

Description

PVC Water Stoppers

PVC Waterstops are profiles based on specially formulated plasticized PVC composition. Waterstops are used in concrete masonry construction of hydraulic structures to safeguard from hydrostatic pressure and water seepage. Waterstops also withstand expansion or contraction of joints and take care of any deflection or displacement arising due to change in temperature or settlement of foundation eliminating danger of cracks. These are engineered a s Water Tight Seals in poured concrete structures.

Selection Criteria:

Selection of the waterstop depends upon the hydrostatic pressure of safe passage of seepage water. Where substantial expansion/contraction of joint takes place. Dumb Bells type should be used. In case differential settlement is expected and a firm grip in concrete is desired, serrated types should be used. moreover, following points should also be noted while selecting PVC waterstops.

    The overall width of the waterstop should not be greater than the thickness of the concrete.

    The distance form the face of the concrete to the waterstop must not be less than half the width of the watestop.

    The width of the waterstop must be atleast 6 times the largest aggregate used for satisfactory compaction.

    

PVC Water Stops

Colour:

• Black/White length in 25meters or as desired colour & length.

Note: We can manufacture and design of PVC Stopper as per requirement.

Installation & Jointing:

Firstly one half of the waterstop is embedded in the concrete leaving the second half extended. Second half is also embedded leaving the centre bulb free from expansion and contraction. Care should be exercised in pouring concrete without misalignment the waterstop. Following joints may be fabricated by means of simple tools and heat fusion/welding.

Properties:

• Optimum resilience
• High Elasticity & Stretch Strength
• Immune to Corrosion
• Excellent weather resistant
• Effective in tropical climates
• High Mechanical Strength
• Good aging & longer life
• Unaffected by acids, alkalies, metals salts and other chemicals
• non-hazardous and Fire retardant
• Lower water absorption than
• Easy welding & installation
• Withstand high Hydrostatic pressure
• Works as Water tight Seals
• Allows safe passage of seepage water
• high Tensile Strength
• Can bear shocks of heavy turbines, Earth quakes, Floods.

Application:

PVC WATER BAR

PVC Waterstop Ribbed with Bulb

PVC Water-stops or Water bars are used in concrete joints waterproofing in basements & water tanks.

PVC water stop seal or PVC water stops are for use in concrete joints subjected to hydrostatic pressures. After being embedded in concrete, PVC water stops fill up the joints to form a continuous watertight diaphragm that prevents the passage of fluid. The water stop must be designed and installed properly to accommodate joint expansions, contraction and lateral & transverse movements. In addition to these consideration the water stop must be compatible with the concrete system and the liquids and chemicals to be contained or controlled.

Our premium quality product pvc water stop seal is a specifically formulated plasticized pvc composition. Our water stoppers are basically used in concrete masonry construction of hydraulic structures for safeguarding them from hydro-static pressures and water see pages. These seals are made of durable quality material and are widely demanded.

We are highly recognized manufacturer and exporter of rubber sealant and water sealing solutions. Our product PVC water stop seal play a critical role in the integrity of concrete structures. PVC water stops fill up the joints to form a continuous watertight compartment.

we manufacture various industrial seals such as water stop seals and other construction items. These seals are made with complete precision and attention to each and every detail so that the best can easily be produced and supplied to the clients. These seals are perfectly in accordance with the clients specifications and demands. Made of durable quality material these seals are competitive in price and cater to the needs of various industries.

 

 Water Stoppers are available in a wide range of Width, Thickness & Designs, like dumbbell type, Ribbed with central bulb. Thickness range from 3mm to 12mm, width range 150mm to 300mm.
