PVC
Our PVC Waterstop is made from new materials not reprocessed or reclaimed materials. Unaffected by normal range of concrete or concrete additives. Will not discolor concrete nor produce electrolytic action. Will perform over wide temperature ranges -35° to 175°F. PVC Waterstop is used where concrete is subject to hydrostatic pressure. Provides a positive seal to contain water above or below grade. PVC is most suitable for most common construction. For specific chemical resistance, please call. There are considerations when choosing a waterstop; hydrostatic pressure, wall thickness, type and size of joint, movement and chemical resistance. Dumbbell types and ribbed no center bulb styles are used where no joint movement is expected. Center bulb type can be used in both expansion
and construction joints subject to movement. Split Waterstop allows waterstop to be used easily in bulk head forming. For walls and slabs that are less than 9" thick, typically 4" to 6" waterstop is used. For thickness over 9", typically 9" is used. Waterstop irons must be used for all splicing requirements. See next page for splicing details. There are several important requirements for waterstop joints; Waterstop must be properly located and braced during concrete placement, center bulb on joints. Waterstop must be clean of foreign matter including concrete splatter. Must be properly vibrated and consolidated. Splices must be done right. Factory splices are available on request. Specifications: Corp of Engineers CRD C-572.

Chemical Resistent
TPE-Rubber Waterstops greatly expand the scope of conventional Waterstops because they do not degenerate under a host of aggressive chemicals, solvents and hot petroleum oils that would destroy PVC. TPE Rubber Waterstops are capable of withstanding joint movement. TPE Rubber Waterstops also have an added advantage of being joined with our regular Waterstop Splicing Irons. The intended use for TPE Rubber Waterstops is for primary and secondary containment facilities where compatibility, resistance and performance values determine the choice based on the specific application test data. TPE Rubber Waterstops are available in 4", 6" and 9" ribbed centerbulb design; which provides for movement within a joint and may be used for above or below grade applications.

Heating Iron
For PVC Waterstop, cut ends square and hold both sides against iron to 350°- 380° F. Do not allow the iron to reach 400° F, PVC will degrade and turn dark color. When about 1/8" to 1/4" of material becomes soft and gummy, remove the iron and press ends firmly together. Hold tightly and allow material to cool before applying stress. All center bulb waterstop must be aligned.For TPE Waterstop preheat iron to 380° to 410° F. 115 volt, 6 amps, 6' cord.

Splicing Technique
A warm-up time of approximately 5 to 10 minutes is necessary to bring the splicing iron to the required 350°-380°F. The entire splicing operation involves three simple steps. Do not allow the iron to reach 400°F. PVC will degrade and turn dark. For TPE Waterstop, preheat iron 380° to 410°F.
Overlap the two pieces of waterstop to be sliced and then cut with sharp knife or saw. This assures matching edges.
IMPORTANT: Edges must be cut straight.
Press the straight cut against the sides of the pre-heated splicing iron until the PVC melts, an 1/8" to 1/4", the material becomes soft and gummy. This takes approximately 3-5 minutes.
Quickly remove the splicing iron and press the melted edges together to form a neat butt-splice. The joined sections should not be stretched or moved for 1 minute. To cool the material quickly, use cold water. Typical spliced sections and the manner of accomplishing them, are shown above.

Bentonite
Waterstop-RX® is a concrete construction joint waterstop that provides a permanent seal by expanding upon contact with water. Waterstop-RX® is an active sodium bentonite based waterstop that is designed to replace conventional passive PVC dumbbell waterstops, thus eliminating the requirement of split-forming and product seam welding.
Waterstop-RX® is manufactured in lightweight, flexible coils that can be installed in both hot and cold weather. The product is adhered to concrete, steel, and PVC (pipes) with CETSEAL sealant/adhseive; at or exceeding the required minimum distance from the exterior concrete surface.
The key to Waterstop-RX® is sodium bentonite. Sodium bentonite swells when in contact with water, forming an impermeable barrier. This swelling property allows Waterstop-RX® to form a permanent pressure seal within the concrete joint, thus eliminating water migration over or along the waterstop.In addition to forming a positive pressure seal, the products expansion properties allow it to seal small cracks and void areas.
Waterstop-RX® is designed for structural concrete with a minimum of 3,000 psi. RX 101 and 101T, require a minimum 3" of concrete coverage. RX 102 requires a minimum concrete coverage of 2".
RX 101 and 101T are designed for vertical and horizontal reinforced concrete 8" thick or greater, with two rows of reinforcing steel. RX 101 has more water resistance and will react slower in water or wet conditions before concrete is placed. RX 101T (trapezoidal) is recommended for shotcrete or gunite concrete construction, extreme hot weather and difficult applications. RX 102 is designed for vertical reinforced concrete 5" thick or greater; and horizontal reinforced concrete 4" thick or greater. RX 102 is designed primarily for concrete with one row of reinforcement.
CETSEAL is a multi-purpose, low VOC, 100% solids, single component polyether moisture cure adhesive used to secure Waterstop-RX® into position. Apply a continuous bead of CETSEAL to substrate then install Waterstop-RX® before CETSEAL skins over and cures within 30 minutes. Adhesive yield will vary with use, substrate and application.

Hydrophilic
Hydrophilic waterstop is a chemically modified natural rubber. This patented process chemically binds hydrophilic agent to the rubber. This permits the seal to undergo controlled expansion when in the presence of moisture. This expansion capability provides a "double locking" waterstop. One from rubber's natural resilience and one from the expansion. Any void within the limits of the products volume expansion coefficient, will be filled by the expansion of the seal when it is hydrated. Excellent durability and resistance to chemicals. It can perform in a wide range of solutions such as salt water and cement water. The material does not contain any toxic substance or heavy metals and is environmentally safe.
