INJECTION HOSE system

Since the early 70s injection hose systems have been used alternatively or in addition to joint profiles and metal water stops. It is an injectable joint filler in tube or channel form. Subsequent leaks can be sealed by injecting polyurethane resin, acrylate resin, cement suspension or cement paste.

Material to be used

Epoxy resin
Polyurethane
Cement suspension
Acrylat gel)

Aims of application

Well-planned sealing, e. g. in addition to a joint profile or metal water stop
Well-directed sealing by additional injection

Demands on injection hose systems

Adequate cross section and passage of the injection canal
During concreting no cement slurry may enter the injection canal
Even distribution and discharge of the injection material over the entire length of the injection hose
High dimensional stability, no kinking of the system when changing the direction

Advantages

Easy installation and flexible adaptation to the joint system
As internal sealing for construction joints in concrete components with high water penetration resistance
Sealing additional to joint profiles or metal water stops
Possibility of sealing construction joints in concrete and reinforced concrete structures
Reasonable, technical method for preventive as well as additional sealing
Injection hose systems can also be installed wherever the installation of joint profiles or metal water stops is extremely complex for structural reasons
The suitability of injection hose systems is documented by national technical approval (Certificate no.: P-SAC 02 / 5.1 / 15-252)

Example of application

Injection hose systems against soil moisture and non-pressing water
Pressing water up to a water pressure of 2 bar
Creation of a water-impermeable construction joint in concrete structures by scheduled injection
Use in e. g. hydraulic structures, sewage treatment plants, underground garages, tunnels

Information

A check list for site "Supervision injection hose systems" and an injection journal can be found in the annexe of the DBV information paper:

Injection Hose Systems and Swellable Sealing Strips for Construction Joints, edition 2010
German Concrete and Construction Technology Association, www.betonverein.de
The model administrative regulation Technical Building Regulations (MVV BT) 2015 edition 15 January 2020 of the DIBt and its implementation in the respective federal states should be taken into account in the plannung and use of injection hose systems

Installation

The injection hose shall be fixed tightly at to the hardened concrete building component element by continuous anchoring fixing so that it cannot float on fresh concrete. Normally the injection hose is fixed with special fastening clamps spaced about 15 cm, however, the spacing has to be adjusted to the conditions on site. In the area of crossing hoses lay them so that they cannot block each other (e. g. by mutual injection).

Opening pressure
The injection material flows out of the injection hose at low pressure between 0.5 to about 5 bar

Information about installation

Length of injection hose: about 8 – 10 m
The injection hose has to lie flat on the first section of concrete to avoid any reduction of cross section
Fix injection hose, e. g. with fastening clamps, the spacing of the injection hose to the outside of wall should be ⅓ to ½ of the wall thickness
In areas where two hoses meet they shall overlap each other by about 15 cm and lie parallel spaced about 5 cm
Indicate the location of the injection hoses in the drawings
