Product Details

FORSPEC PREBAR PVC WATERSTOP – Cross Piece is a prefabricated thermoplastic PVC fitting designed to connect four PREBAR PVC Waterstop profiles at a cross-junction within cast-in-situ concrete joints. Factory fabricated to ensure accurate dimensions and dependable performance, it provides a secure and watertight solution for complex concrete joint layouts.

Key Features & Benefits

Factory-Fabricated Precision: Manufactured under controlled conditions to ensure consistent quality and reliable waterproofing performance.

Maintains Waterproofing Integrity: Creates a secure four-way intersection that preserves continuous waterstop protection throughout the concrete structure.

Reduces On-Site Fabrication: Minimises installation time and labour by eliminating the need for complex field welding and joint fabrication.

Durable Thermoplastic PVC: Resistant to water ingress, moisture, and common environmental conditions encountered in concrete construction.

Compatible with PREBAR PVC Waterstop Systems: Designed for seamless integration with corresponding PREBAR PVC Waterstop profiles.

Ideal for Complex Joint Configurations: Suitable for intersecting construction and expansion joints in water-retaining and below-ground structures.

Suitable for Critical Structures: Commonly used in basements, tunnels, water tanks, reservoirs, retaining walls, wastewater treatment facilities, and civil infrastructure projects requiring reliable joint waterproofing.

How to Use

Heat weld directly to PREBAR PVC Waterstop rolls.

Technical overview

PREBAR PVC Waterstop Cross Piece is a factory-manufactured four-way PVC junction that connects four PREBAR PVC Waterstop runs at a central intersection in cast-in-situ concrete, in an external or an internal configuration. It is heat welded directly to PREBAR PVC Waterstop rolls and is available in 150mm and 250mm to match the profile width. Forspec publishes no product-specific Technical Data Sheet, test report or certificate for the PREBAR prefabricated fittings: the Technical Data Sheet link on the Forspec product page returns the 4-page PREBAR Prefabricated Fittings range brochure. No performance figure, standard or classification is claimed for this fitting. The BS 2782 test results published for PREBAR PVC WATERSTOP belong to the waterstop roll and have not been carried across.

Key applications

Basements
Tunnels
Retaining walls
Water tanks
Foundations
Lift pits
Reservoirs
Four-way waterstop intersections in cast-in-situ concrete construction joints

Forspec publishes no limitations, safety data or handling instructions for the prefabricated fittings themselves. Install as part of a PREBAR PVC Waterstop system and apply the limitations in the PREBAR PVC WATERSTOP Technical Data Sheet: the fitting must be fully encased in concrete on both sides with the design cover maintained, centred and correctly aligned in the joint, and must not be installed over dirty, wet or contaminated surfaces. Do not fold, kink or crease it. All joins must be fully heat welded; taped, glued or overlapped joins are not acceptable. Do not overheat during welding, as PVC degrades above the stated welding range. Do not store above 40C or in direct sunlight. Joint design, profile selection and hydrostatic duty are the design responsibility of the project engineer.
