MASONRY REPAIR

Most jobs we provide for Masonry repair is due to rusting structural  steel. Once the steel has been treated and/or replaced, the type of  concrete used for the repair is important for matching texture. If the  concrete is not painted then we closely match the texture color of the  blend for the patched areas.

Treating Rusting Rebar - Why does it happen?

Spalling is when the steel reinforcement in a concrete structure  begins to rust, resulting in a greater volume than the steel. The  greater volume creates tensile stresses in concrete which leads to  cracking, delamination and spalling of the concrete. Concrete cover  affects how soon the spalling is visibly noticeable.

Why is there steel reinforcement in concrete?

Concrete structures have steel reinforcement to help with tension  which in turns helps the concrete structure by providing tensile  strength. Concrete has a high alkalinity which helps provide a passive  resistance layer to the surface of the steel to aid in corrosion  prevention.
