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.

For applications where a re-inject able system is required, SealBoss Inject Tube System is used in combination with SealBoss ® 2400 Acrylate Gel as the Inject Tube system can be flushed with water prior to and after the products set. The system is also compatible with micro-fine cement injections.

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.
