Pvc Water Stop - High-pressure Resistant, Ozone & Chemical-resistant Material | Prevents Leakage & Seepage In Concrete Structures

Our
immense technical know how and innovative infrastructure enables us
to manufacture and supply PVC Water Stop. These products are used in
different dams, canals, aquaducts, water reservoirs, culverts,
containment structures and tunnels to prevent leakage and seepage.
Known for their sturdy construction, these products can withstand the
high pressure of water. Packed in special packaging material, PVC
Water Stop is delivered to the clients in a safe and secure way.

Other details:

Concrete structures are only as watertight as the water stops that join them. Eexxon water stop (s) stop leaks before they start

In the concrete structure it is necessary as a device against possible risk of discomfiture that tends to be caused in concrete structure follows by the climatic, geo-disturbances and frictional impasse. This phenomenon results in expansion and contraction in concrete structure. This expansion and contraction results in leakage/seepage of water exposing the structure to risk of cracks or dismemberment.

Eexxon P.V.C water stop joints are manufactured from specially Formulated P.V.C. Compound to resist a broad spectrum of ozone, oxygen, alkalies and other aqueous born chemicals and to meet diverse. Nature of concrete lining for long term satisfactory performance when embedded in to concrete.

Technical Specifications

TYPE(S) OF CONCRETE JOINTS

Expansion joints - Allow expansion AND contraction of a concrete structure without generating potentially damaging forces within the structure itself Expansion joints are usually a complete 'gap' between adjacent bays, i.e., there is a definite break in the concrete and any reinforcing steel that may be present. Where adjacent bays are 'tied' together by means of dowel bars, these dowels are sleeved in one of the bays to allow expansion to take place without generating stresses within the slab.

Contraction joints - Also known as 'shrinkage joints', this type of joint allows only for contraction or shrinkage of the slab, as can be anticipated during the curing process. &, CHANGE IN DIMENSION in part of concrete structure

Construction joints - Although this type of joint is not a true movement joint, it is a commonly formed joint in concrete construction and so is included here for completeness. Construction joints can be horizontal or vertical and are formed when placement of the concrete is interrupted for some reason. It may be the end of a day's work or it may be that some other work needs to be completed before resuming the placement, but the result is the same - a 'surface' is formed as the placed concrete cures, and then fresh, plastic concrete is poured against this 'surface' as some later point in time.

Direction

• Uncoil waterstop atleast before 12 hours prior to installation for ease of handling and fabrication
• Position waterstop to ensure proper distance
• Care the waterstop from damage during installation.
• Clean concrete joint after first pour to remove debris and dirt.
• Center waterstop on joint, with approximately one-half of waterstop width to be embedded in concrete on each side of the joint.
• Allow clearance between waterstop and reinforcing steel of a minimum of 1.5 times the largest aggregate size. Prevent rock pockets and air voids caused by aggregated bridging.
• Ensure center bulb is not embedded at expansion joint.
• After first pour, clean unembedded waterstop leg to ensure full contact of second concrete pour. Remove laitance, spillage, form oil and dirt.
• Repeat all steps for the second pour.
• Reference Standard IS - 15058 / 2002 & ASTM.
