WATERPROOF X®1

INJECTION HOSE SYSTEM

PRODUCT DESCRIPTION

Waterproof X®1 is state of the art, multi-injectable injection hose system, used
to seal joints in concrete against water egress. Waterproof X®1 injection hose is used to transport grouting materials and then disperse them into the concrete joint via micro openings along the hose.

Waterproof X®1 injection hose is a highly resistant, robust, fully tested, single channel injection hose system that is made of specially developed PVC materials.

Waterproof X®1 has the ability for multi-injectable grouting processes. This ability allows the system to be re-injectable for the life time of the structure, giving total peace of mind and assurance that the structure can be fully sealed and resealed. This is a great advantage if movement or shrinkage occurs between concrete joint faces of the structure.

ADVANTAGES

  • A perfect sealing solution
  • Fast and easy to install
  • Economical handling due to simple, easy connection of accessory pieces
  • Injection hose is supplied on handy spool that allows for uncomplicated cutting to length due to numerical markings printed at every metre along the hose
  • Low consumption of grouting material due to optimum inner hose diameter
  • Maximum safety features as grouting processes are performed under very low pressures
  • Simple grouting process with multi-injectable capabilities
  • Multiple grouting materials can be processed
  • Ultimate grouting processes performed at 10m-12m intervals between injection points. Overlength injections of up to 30 metres can be achieved with special injection processes and use of correct equipment
  • Highly economical due to rapid laying times and injection processes

GENERAL INFORMATION

Unsealed construction joints can decisively lessen the durability and utility-value of concrete structures. Nowadays, injection hose systems are being increasingly used for sealing construction joints in waterproof concrete structures. Their advantages are numerous when compared to traditional waterstop systems. It is not always required to inject the hose but usually only if the joint is leaking, thus making it a very cost effective procedure.

The area of application is usually at the construction joint (other application areas can be applied) where hardened and fresh concrete have to be joined in such a manner that the sealing effect of the construction joint is fulfilled equally.

Simple and rapid installation is achieved at all positions, levels and angles. Waterproof X®1 can also be laid where the installation of traditional systems is constructively impossible; for example, on geometrical complicated surfaces such as sheet piling, diaphragm and contiguous pile walls and old to new construction.

Reliable sealing of construction joints, cracks in construction joints, and destroyed areas of concrete (gravel pockets and cavities) can be filled via Waterproof X®1. Previously this has not been possible to achieve with conventional waterstop systems.

Waterproof X®1 is used in all types of construction joints and in particular during the construction of water and sewage treatment plants, dams, barrages, underground garages, tunnels and the construction of foundations, basements, bridges and power stations.

WATERPROOF X®1 MICRO OPENING DIMENSIONS

waterproof x1

Waterproof X®1 injection hose is equipped with micro openings (injection ports), equally spaced over its entire circumference, which provides Waterproof X®1 injection hose with optimum grouting characteristics. During the injection process, the microscopic ports open at 1 Bar and injected material is then allowed to perform its task of penetrating the construction joint that requires grouting. As a result, a more secure and longer lasting sealing of the construction joint is achieved.

The micro openings prevent any infiltration of concrete silt and foreign bodies into the injection hose itself. After successful injection, the pressure is released, which causes the micro openings to close. The injection channel can then be flushed out with water, without the threat of any injection material seeping back into the injection hose or water injecting into the joint during the flushing process. The specially designed micro openings are designed in such a way that they act as valves, allowing the release of material out of the hose but not back into it.

INJECTION MATERIALS

  • Acrylic Gel
  • P.U Resin
  • E.P Resin
  • Ultra-Fine Cement

Note: Only acrylic gel or ultra-fine cement can be used for re-injectable processes.

SYSTEM COMPONENTS

  • Waterproof X®1 injection hose – 120 metres roll – numerical markings every metre on hose.
  • CJ-Reinforced PVC Hose – only required for special applications to channel grouting material.
  • Varioclix D Injection Point – dual injection point (can split into two single injection points).
  • Varioclix BS Injection Point – dual injection point with blue spacer.
  • CJ-Hose Clamp – holds hose into position on concrete surface, used in conjunction with impact plug.
  • CJ-Impact Plug – securing pin for use with hose clamp.
  • CJ-Hose Joiner – to join CJ-Reinforced PVC hose to Waterproof X®1 hose.
  • Injection pumps, Injection resins & Injection nipples – used to perform the injection process.

INSTALLATION PROCEDURES

  1. Waterproof X®1 injection hose is preferably positioned in the middle of the substrate. This is not possible with a minimum of 100mm concrete cover from any outside edge.
  2. Waterproof X®1 injection hose must lie flat on the 1st concrete section with the hose clamps spaced at 150mm apart. If the concrete surface is rough, then the hose clamp spacings need to be closer so the hose is touching the surface of the concrete.
  3. The standard length of Waterproof X®1 injection hose, between injection points is approximately 10-12 metres. This will help achieve an ultimate injection process.
  4. At the injection point locations where each individual hose length meets, an overlap of 150mm is required and with the two hoses laid parallel to each other at a distance of 30mm apart.
  5. The Injection Points are to be installed in such a way as to allow access at all times.
  6. For guaranteed security and performance, it is recommended that two layers of Waterproof X®1 be placed if the concrete substrate is greater than 1000mm wide or thick.
  7. Overlength applications of up to 30 metres are possible but the correct installation procedures, and use of SX-T Acrylic Gel injection material, must be used via a 2K Pump.

Note : Please refer to the manufacturer’s installation procedures and guidelines (available upon request).

SIMPLE INJECTION PROCESS FOR INJECTION HOSE SYSTEM

  1. Check the continuation of the injection hose by flushing with water or with air.
  2. The injection hose is injected via the injection point until the injection material is fully flowing from the vent end (opposite end of injection hose). This vent end is closed by means of an injection nipple as soon as the injected material flows freely (without air pockets) from the vent.
  3. The flow and extent of the injection material in the concrete joints can be monitored during the injection process by means of the injection pump’s pressure gauge, if using a 2K or 3K pump. If using a 2K or 3K manual pump, then monitoring is done manually, by feel and vision.
  4. The injection process is continued until constant pressure has been reached. Constant pressure indicates that the concrete joint is absorbing no more injection material and thus signaling the end of the process.
  5. Any injection material still within the injection hose is simply flushed out by means of a water pump and is a simple and easy process. Flushing must be undertaken prior to the injection material curing to gel form, otherwise, the injection hose will be blocked.
  6. On completion of the flushing process, the injection hose is ready for future re-injections, if required. CORK JOINTING SYSTEMS recommends the use of a 3K Manual Pump as the third container is water and is used for flushing the hose after each injection process (please refer below photo of the 3K Manual Pump).

Note: Installation and injection method processes are available upon request. Fully trained specialist contractors are available to perform the installation and injection processes for Waterproof X®1.
