Cracks and cavities in structures are a generally present problem in construction engineering. Faulty-parts of this type can impair the stability as well as utilization of the building and can clearly shorten the „ life-expectation „ of a structure.

The injection-systems of IPA offer proven and innovative solutions.
For more than thirty years IPA was engaged in the development and improvement of injection-systems.
Competent advice and practical experience gives you security in application of IPA injectionsystems.
The investigation of the cause for damage is normally the beginning of the designing of sealing works or repairs.
Only if the causes for damage are known, the selection of the matching injectionsystem can be decided effectively.

Epoxy-systems are selected when high strength is the objective. Coupling injections of structural parts with inferior strength are more and more carried out with mineral injectionsystems, which can be adjusted by the selection of the cementing agents, aggregates and additives according to the requirements.

A sealing injection of defective parts, which are continuously under movement (e.g. highway bridges), takes place with PU-resins, which harden to a permanently elastic end product.
The various solution-possibilities are described in the following with the IPA injection-systems. These are completed by the broad service-performances of IPA technicians during damageinvestigation, planning of repair works and their execution
