Little has changed in sealing technology for concrete structural joints since the introduction of PVC (polyvinyl chloride) waterstops in the 1940’s. Today, most structural joints still rely on this sixty year old technology to prevent fluid passage through the joint. However, each year millions of dollars are spent on secondary waterproofing products to stop resulting leaks. The problem is that conventional waterstops are severely limited in their ability to provide a continuous barrier against liquid penetration through the joint. They are difficult to install and secure properly, easily displaced during concrete placement, and prone to failure during joint expansion or separation.
In response to these problems as a custom plastic extrusion company, Paul Murphy Plastics has developed WIRESTOP, a patented product, which represents an improvement on PVC waterstop technology and meets the engineer’s requirements for an effective primary joint sealing system. The secret of WIRESTOP’s performance is a series of continuous galvanized steel wire loops along both edges of the waterstop which provide a completely self-contained attachment system for tying WIRESTOP to the reinforcing bars. The quick, inexpensive, accurate fastening ensures WIRESTOP’s proper positioning and holds it securely in place during the heavy load strain of the pouring concrete.
The WIRESTOP loops are an integral part of the PVC waterstop for concrete joints so there are no holes for the fluid to penetrate.
This is in sharp contrast to conventional waterstops, which are installed by inserting “hog rings” or other devices through the waterstop into drilled or punched holes.
Even if the hog rings are not torn out due to the weight of the pouring concrete, a common occurrence, the holes inevitably become sources for subsequent leakage through the waterstop. As a trusted PVC Waterstop manufacturer, we are committed to advancing technology to provide effective, long-lasting solutions for concrete joints.

A New Level Of Performance:
Because it is firmly anchored by the integral wire loops, WIRESTOP stands up to the stresses of concrete placement. During consolidation, the vibrator heads can be positioned closer to the WATERSTOP sealed joint, ensuring stronger concrete matrices in this critical area.
An added benefit is provided by the fact that wet concrete flows freely through and around the WIRESTOP loops during placement and consolidation. This produces a strong mechanical bond between the WIRESTOP and the cured concrete on both sides of the joint, creating a watertight seal throughout the joint’s range of movement.
A Proven Technology:
WIRESTOP has been proven in thousands of joints on hundreds of critical projects, including treatment plants, dams, tanks, retention structures, nuclear waste containment vaults, tunnels, and many others. It is the modern answer to the structural engineer’s long-standing need for an effective, economical primary joint sealing system.
