Wateproofing

Protects against water migration, water can migrate through; rain, air/ vapour intrusion, leakage and ground settlement. There are several types of waterproofing; ones that form a continuous adhesive bond to concrete poured against it, the type that is applied in a self- adhering sheet form and trowel spray or brush applied versions, all of which are a must for building integrity.

  • Under/slab
  • Cold fluid applied
  • Self-adhered sheet applied

Concrete Rehabilitation/Restoration

The process of repairing old deteriorated or corroded concrete construction and restoring it to the original capacity. Restoring is simply bringing the structural integrity back to engineering standards without the costly expense of total reconstruction. Some of the ways these structures are repaired is by strengthening, injecting and form and pour.

Protective Coatings

High performance coatings are designed to protect surfaces from a corrosive or abrasive environment, these coatings are mainly used for primary and secondary containment. Primary containment, as one example, would be the inside surfaces of a tank or vessel. The outside surfaces would be considered secondary, as is, a spill containment area as we. All these require a knowledge and experience in the various types of preparations and applications. Architectural finishes on the other hand are mostly decorative and are not as complex.
