Concrete Repair

Utilized throughout the construction industry, from highways to skyscrapers, steel reinforced concrete, allows Architects and Engineers to construct ever more complicated and exciting projects. Unfortunately, if left unprotected, the effects of the environment can take their toll.  Damage to concrete by freeze thaw action, mechanical damage, acid rain and even chemical reactions between the concrete and atmospheric CO2 can have a detrimental effect on our buildings and infrastructure. 

We believe the best way to complete concrete repairs, is with thermally compatible and dimensionally stable, cementitious materials. This is why in side by side testing of major suppliers, our concrete repair products consistently come out on top. 

When used in conjunction with our comprehensive range of compatible waterproofing and corrosion protection products, Stonhard Construction Solutions offers a complete repair and protection solution in every environment, no matter how challenging or difficult.
