Injection Tube System

Injection Tube System / Injection Hose System

What is the Injection Tube System?

Injection Tube System is a grout delivery system, meant to seal cold and construction joints, mainly in new construction where fresh concrete or shotcrete is applied. In order to connect with already cured concrete structures, creating a cold joint. When installed prior to pouring the concrete, the injection tube permits the injection and delivery of resins & grouts into the cold joint to provide an instant and permanent seal.

The SealBoss Injection Tube System is designed around a solid core, perforated PVC Tube.

The Injection Tube is installed in joints prior to the pouring of new concrete to waterproof and seal any cracks or voids, that may be present. The SealBoss Injection Tube System enables a permanent watertight joints seals.

Easy to install and reasonably priced – The SealBoss Injection Tube System simplifies the job and provides for watertight joints.

SealBoss Injection Tube Type 2 offers a double woven membrane to best protect the inner tube space from water and debris. A clean inner tube assures the best results.

The SealBoss Injection Tube System is an efficient and easy to install system to create water tight cold joints

A well-known characteristic of concrete is shrinkage while curing. Stress caused during this time and temperature changes provoke the development of small cracks and fissures.

Several design and reinforcement techniques help to control this effect, but cannot control them completely. Fine cracks of sometimes less than 0.1 mm are inevitable. These cracks are considered normal and generally do not cause any problems. However, at cold joints, the tendency to form larger cracks cannot be reduced.

Since old and new concrete do not bond together homogeneously and do not form a monolithic concrete body, stress cracks concentrate mainly in these areas. They easily conduct water and may cause severe damage.

The SealBoss Injection Tube System for sealing cold joints utilizes the natural tendency of concrete to form cracks. A special tube system is installed at the joint where leaks are most likely to occur. The system allows resin injection directly into the joint through a protected porous tube after completion of the structure. The resin penetrates through the perforation of the tube and fills the cracks and voids of the cold joint area thereby sealing the structure.

To be effective, the system must have certain properties. The tube must be sturdy enough to withstand the high pressure of placed concrete and it must resist concrete slurry penetration. On the other hand the injection resin must be able to penetrate the hose at a moderate injection pressure. The installation and injection process must be suitable for construction sites. The SealBoss Injection Tube System is designed to meet these requirements.

Before pouring the new concrete the tube shall be attached to the existing surface as tight as possible and usually towards the middle of the future cold joint using suitable clips or by attaching it to the existing rebars. It is crucial that the hose is tightly fixed in the center of the joint area so that it can neither move nor lift during the concrete placement. Six to twelve inches between clips are typically recommended.

The hose must be placed in a manner that it will not touch the outside surface of the structure at any point. To allow sufficient injection pressures, the maximum length of injection tube should not exceed 30 feet.

What is the Injection Tube / Injection Hose System ?

SealBoss Injection Tubes are intricately designed with perforations to serve as a conduit for grout, ensuring a seamless and effective delivery to the required areas.

Injection Tubes are strategically positioned in construction joints before the concrete pour, embodying the epitome of purposeful design and thoughtful manufacturing. These tubes function as a reliable chemical grout delivery system, engineered to seal cold joints in their entirety. This proactive approach results in the formation of a durable barrier, safeguarding the concrete and its embedded rebar from potential damages and corrosion caused by water ingress.

The SealBoss Injection Tube System is an engineered, cutting-edge waterproofing solution, specifically designed to halt water migration through cold joints. These occur when new concrete fails to bond with existing concrete. With its exceptional performance and preventative attributes, our Injection Tube System serves as a critical line of defense in maintaining the integrity and longevity of your concrete structures.

By integrating the SealBoss Injection Tube System into your construction projects, you are choosing a solution that embodies excellence, resilience, and a steadfast commitment to safeguarding your structures against the elements.

How does the Injection Tube / Injection Hose System Work ?

“Often referred to as “inexpensive insurance”, the Injection Tube System is specified by consulting engineers as a built-in safe guard…”

The Injection Tube is installed onto an existing substrate at the interface where new concrete is to be poured. Placed centrally, the tube acts as a delivery system, starting the delivery of SealBoss injection resin from the middle of the seam and penetrating the cold joint evenly to front and back.

SealBoss chemical grout be injected as soon as the concrete has reached enough strength, preferably after the concrete has had time to shrink and/or settle. Careful placement and fixing of the Inject Tube is advised for good success.

Once the encasing concrete has hardened sufficiently, the hose can be injected with SealBoss injection resin or low viscosity polyurethane leak-seal foam.

Primed with resin and then closed at one end with a SealBoss Screw-In Packer and Zerk Fitting, the injection pressure is increased. With rising pressure the low viscosity SealBoss chemical grout is evenly dispensed through the perforated Inject Tube into the cold joint.

After successful installation and injection the cold joint is now permanently sealed in its entirety.

Injection Tube Type 2

Water Tight Cold Joints and Pipe Joints

What is an Injection Tube?

Injection Tube Systems – a.k.a. Injection Hose Systems – are used for sealing structural joints and cold joints in below-grade concrete structures such as tunnels, tanks and parking garages. Cold joints form when new concrete is poured on an already existing cured concrete substrate.

SealBoss Injection Tube acts as a delivery system for injection resins and grouts, to travel into the concrete joints and matrix’s, sealing joints, cracks, voids and honeycombs in the process.

If left untreated, cold joints in concrete structures enable water migration driven by hydrostatic pressure – leading to concrete deterioration, rebar corrosion, and further infrastructure damage.

Injection Tube Type 2

The SealBoss Injection Tube Type 2 is constructed from a specially formulated perforated plastic core tube and two independent woven membranes, in order to prevent the infiltration of concrete particles and contaminated water, during and after the concrete pour. Under pressure injection, the woven membranes provide for an even distribution of injection resin along the tube and into the cold joint. The flexible nature of the Inject Tube allows it to follow uneven substrates and corners.

The Injection Tube Type 2 System is an essential product for creating water tight cold joints in poured concrete structures.

Each new pour of concrete onto existing concrete creates a joint of low cohesion called a cold joint. Additionally shrinkage of the concrete causes added stress, which given enough time can crack and erode due to fluctuations in weather and temperature.

The installation of the SealBoss Injection Tube Primary Water Stop System and subsequent injection with SealBoss Resin, creates a monolithic seal in cold joints while penetrating into fine cracks and fissures. Thus preventing any future migration of water.
