Of course, concrete will withstand exposure to water. After all, concrete’s innate durability is one of the reasons the material is used so extensively in construction.
This includes exposed civil infrastructure such as bridges, wharves, and transport elements.
We need to remember that concrete is porous, despite the best developments of the industry, and that moisture vapour can enter it.
We’d like to point out the impact of moisture on concrete longevity.
Moisture and moisture vapour carry contaminants – reactive chloride, nitrate and sulphide ions, for example – which encourage premature deterioration of the concrete and the reinforcing steel.
Once early deterioration has commenced, cracking will worsen, providing additional avenues for moisture to enter the structure.
A cycle of deterioration sets in, reducing the structure’s service life.
Hence, the need for waterproofing treatment. Protecting the concrete is not optional.

MARKHAM recommends waterproofing with penetrating hydrogel treatments.
Hydrogel treatments IMMOBILISE moisture. This means moisture doesn’t enter, and moisture doesn’t move around. It also means the existing moisture remains, as a hydrogel, within the concrete matrix. This is part of the “CIVIL-TECT® approach, tailored around whatever particular civil infrastructure project is at hand.
Concrete waterproofing hydrogel treatments are ideal for exposed concrete structures, protecting against environmental demands and contaminants introduced by traffic and loads during the structure’s use.

For NEW concrete infrastructure, consider a waterproofing ADMIXTURE – protect the concrete from day one!
For EXISTING decks, for proactive maintenance and to arrest premature deterioration, SPRAY-APPLIED hydrogels can play a vital role.
