Water can leak into and out of structures due to cracks, failed joints and even through permeable substrates. Once identified, if not treated, further problems can occur including the corrosion of reinforcement, thus resulting in the consequential loss of a usable area within the structure.
Our resin injection systems are designed to stop water ingress through leaks, in concrete, masonry and natural stone structures.
Let's take a look below at some of the most common sources of leaks in a concrete structure.
Typical Sources of Leaks in Concrete Structures
Closing, sealing and flexible bridging of leaking cracks and honeycombing or voids in new and existing structures:
For sealing construction joints in a watertight structure:
Waterproofing joints where the original joint sealing/waterproofing system is damaged or was not properly installed:
Closing, sealing and flexible bridging of leaking cracks and honecombing or voids in new and existing structures:
Repairing and sealing by injection through flanges accessible from inside the structure:
Waterproofing damaged and leaking sheet membrane compartment system:
Sealing leaks due to multiple tie bar holes or other multiple minor leaks:
Successful Waterproofing with Sika Injection Systems
Sika's injection systems can be used at any time - during the initial construction works, or later to extend the service life during any subsequent refurbishment, according to the specific project's requirements. Our injection systems can not only close, flexibly bridge, seal and make leaking structures watertight for the long term, some can also be used to increase or restore structural integrity and load bearing capacity, therefore providing complete and durable maintenance solutions.
Sika's high performance injection materials are also fully compatible with Sika's complete Waterproofing range and they can be used for the repair and sealing of cracks, voids, joints, hoses and compartment systems in many different structures.
