Even materials with high compressive strength like concrete, have the potential to deteriorate with wear and tear, which, left unaddressed, can cause unsafe structures and lead to significant unscheduled maintenance.

Our WSP Opus research team have extensive experience in providing independent condition assessment, maintenance and repair of concrete structures, including water absorption testing and other concrete durability tests.  There are several tests that measure the durability of concrete depending on their environment and use.

Water Absorption Tests

will measure the rate at which toxins and agents can penetrate into the concrete. If the rate is high the resilience of the concrete will weaken.

Permeability tests

evaluates the resistance of concrete against hydrostatic pressure. By nature, this pressure does not occur in concrete above grade -  it must be below the water table of a site or entering a water pathway. 

Chloride permeability tests

is the standard test method for assessing the resistance of concrete journals to the infiltration of chloride; leading to corrosion and structure weakness.

Our concrete technologists

are trained to operate in virtually any situation, including heights, confined spaces, wastewater environments, from floating platforms or boats, and on State Highways.

This type of specialist diagnosis and methodology is increasingly used as an asset management tool to assist in the planning of maintenance and expenditure.

Our New Zealand offices carry out concrete durability assessment and methods throughout New Zealand, Australia, and the Pacific Islands.

They combine detailed visual inspection with specialist instrumented testing, which can establish the cause and extent of any deterioration, as well as identifying technically appropriate and cost-effective options to repair.

For structures with little or no deterioration, assessments can help inform the development of a long-term maintenance and repair strategy, including options for proactive maintenance. Deterioration modelling is used as a tool to predict the remaining life of structures.
