Concrete Water Absorption Test.

Our Services

Measure porosity. Predict durability. Protect assets.

Concrete water absorption test is a critical durability test because it provides a direct measure of the concrete's total porosity and its ability to resist the ingress of water. This is an essential indicator of a concrete structure's potential for long-term deterioration. At Global Lab, we conduct Bond Strength Testing as per BS 1881-122 standard.

Why CWATMatters.

High Water-Cement Ratio

Adding too much water during mixing creates more "capillary channels" as the excess water evaporates.

Poor Compaction

If the concrete isn't vibrated properly during pouring, air pockets (honeycombing) remain.

Inadequate Curing

If concrete dries too fast, the chemical reaction (hydration) stops early, leaving the pore structure open and "leaky."

Guides Mix Design & Material Optimisation

Helps engineers evaluate the effectiveness of admixtures, supplementary cementitious materials, and curing practices in producing dense, durable, and impermeable concrete.

This test Indicates Porosity and Permeability. That links directly to:

Freeze–thaw resistance (less water → fewer freeze cycles causing cracking)

Sulfate attack vulnerability (lower ingress limits chemical reaction)

Alkali-silica reaction risk (less moisture movement reduces reaction likelihood)

Reinforcement corrosion potential (reduced water/chloride movement protects rebar)
