PVC Waterstops

PVTech's Waterstops are high grade Polyvinyl Chloride Resin extrusions that are plasticized and stabilized to offer long life performance in concrete structure against water leakages.


The Waterstops are manufactured with the highest quality PVC to provide the strongest tensile strength and elongation capabilities possible with a superior resistance to alkalies, acids, ozone and waterborne chemicals.



 

PVTech

Our complete line of shapes and sizes assures a long, lasting, watertight seal for every above or below grade concrete structure. PVC Waterstops are available in a wide range of designs and sizes to suit a variety of applications.

Product Types and Description

Internal Construction Joint

Internal Construction Joint Waterstops is placed in the centre of the concrete construction joints. Since this type of waterstop is embedded into the concrete they are designed and incorporated with fins and multiple solid-core ribs along the two lengthwise edges. these fins interlocks the waterstop in the concrete thus providing a superior mechanical bond with the concrete. the ribs are designed with particular angle which anchors with the concrete and further reinforces the mechanical bond. in addition to that angle in the ribs ensures a torturous path for the passage of water.

Internal Expansion Joint

Internal Expansion Joint waterstop is placed in the centre/internal section of the concrete expansion joint. this waterstop has a central hollow bulb which is designed to allow the cyclical and differential movement in both lateral and transverse direction without excessively stretching the material. For greater versatility and superior mechanical bonding, the waterstop is incorporated with multiple ribs and fins on both the lengthwise edges.

External Construction Joint

External Construction Joint waterstop is used at joints of slab on grade or walls that gets backfilled on vertical walls. the profile of this waterstop is flat with multiple ribs and fins along its flanges for better mechanical bond or interlock in the concrete

External Expansion Joint

External Expansion Joint waterstop is used in concrete expansion or isolation joints. these are designed with center bulb with a tear web these type of waterstop is used where large movements in expected tear web keeps concrete out of the bulb during concrete placement upon joint movement, the thin tear web ruptures allowing substantial mechanical deformation of center bulb without stressing the material.

Internal Expansion Joint

Internal Expansion Joint (Bulb Type) waterstop is placed in the centre/internal section of the concrete expansion joint this waterstop has a top side  hollow bulb which is designed to allow the cyclical and differential movement in both lateral and transverse direction without excessively stretching the material. For greater versatility and superior mechanical bonding, the waterstop is incorporated with multiple ribs and fins on both the lengthwise edges.
