Cracks can occur due to building movement or mechanical damage, shrinkage related issues, or thermal expansion. Often it is necessary to provide structural stability or to seal these cracks to prevent water ingress and the acceleration of corrosion related problems such as spalling. WHA provide an array of techniques to re-introduce monolithic capacity of concrete elements or sealing to prevent ingress using specialised plant and techniques as well as state of the art materials, allowing cracks as small as 0.25mm to be injected.
