WEBAC® 150
WEBAC 150 is a versatile PU injection foam resin (SPU) that is particularly valued for its safe and easy application. Upon contact with water, it cures with significant expansion to form a surface-tight, firm-elastic foam with a very fine-cell structure. This makes it suitable for the rapid, temporary closure and sealing of pressurized water-bearing cracks, cavities/voids, and leaks in building construction, civil engineering, bridge construction, and tunnel construction.

- Stopping of pressing water
- Injection in front of the component
- Filling cavities/voids in masonry and concrete in case of water ingress
- Curtain injection without adding accelerator according to National Technical Approval
- Sealing of foundation pits (material curtain - curtain injection in adjacent foundation soil): sheet pile wall, bore pile wall, underwater concrete
- Sealing of anchor heads in special civil engineering
- Sealing in hydraulic engineering e.g. (drinking) water tanks
- Shaft repair
Properties
- Polyurethan-based injection foam resin
- Fast and highly expanding foam
- Foam structure not too rigid
- Adjustable reaction time (accelerator WEBAC B15)
- Good reactivity and extraordinary resistance to alkaline water up to pH-value 13

WEBAC B15 is a universal accelerator for PU injection foam resins and PU combination injection resins. It shortens the foaming reaction time of these resins and is particularly recommended for use at low temperatures.
Injection Packers
WEBAC® Injection Packers
- Classic Line
- Consolidation Line
View detailsWEBAC injection packers are filling nozzles that serve as a connecting element between the injection pump and the structural component. They are available in various designs—such as Drill hole packers or surface packers—depending on the type of injection material and the requirements of the structural component. The packers are characterized by secure attachment within the structural element as well as high pressure and corrosion resistance (stainless steel or aluminum versions).
