Common Reasons Why Concrete Requires Repair

Concrete is widely used for everything from foundations to bridges. Water tanks, buildings, and even dams can be made with concrete. It is a strong, durable, and well understood material. But that doesn’t mean it’s going to last forever without a bit of attention and sometimes repair. In fact, concrete today isn’t even the same as the concrete that was poured for your commercial parking garage twenty years ago. Below are some of the most common reasons that concrete requires repair.


Rebar Corrosion

Concrete is often reinforced with steel rebar. The rebar is meant to help keep the concrete from crumbling. Unfortunately, the opposite seems to be the real problem. If rebar is exposed to excess carbon chlorides or dioxide, it will begin to corrode, causing the concrete around it to crumble too. Rust can burst concrete.


Alkali-Silika Reactions (ASR)

This is a serious problem for some concrete structures that were built before the reaction was well understood. ASR is a reaction within the concrete due to the chemical make-up of some aggregates. Alkaline cement will react with water, form a gel, and then cause cracks in the concrete.


Cavitation | Abrasion

Water will wear away at concrete over time, which is commonly seen in pipes. Abrasion can also be due to physical wear from items such as forklifts.


Freeze-Thaw Deterioration

If air-entrainment isn’t sufficient, the concrete can become saturated with water, which then expands when it freezes. It then breaks down into its component parts: sand, aggregate and cement.


Repair is Possible

Fortunately, it is possible to repair concrete that is showing signs of any of these problems. Depending on the severity, large portions of the structure may need to be re-built. But with the right concrete repair team, you can often avoid a complete tear down. Most importantly, the cause of the deterioration should be identified so that the concrete repairs last and the problem doesn’t reoccur.


Concrete Restoration


In parking garages and other structures

While concrete may seem solid and permanent, time and wear will start to show on any concrete structure or building. Especially in parking garages, where de-icing salts along with the weight and movement of vehicles can put a lot of pressure on the structure, it’s critical to watch for signs of degradation and to have repairs completed in a timely manner. Restoration projects can be completed on bridges, floors, and any structure made of concrete, as long as the problem is clearly identified and a good solution is well implemented.


Reasons for Concrete Restoration

Some of the reasons that concrete in a parking garage or structure needs to be restored have to do with water. Water can leak through cracks or failed joints. Water can also contain corrosive substances and chlorides that breakdown concrete or cause corrosion. And the alkali-silica reaction (ASR) in some older concrete structures can also break down the concrete, possibly requiring a repair or complete rebuild.

Another common problem is rebar corrosion, as rebar can rust and damage the structure of the concrete.


What to Look For

Visual signs of concrete deterioration are cracks, rust stains, efflorescence, water leakage, concrete spalling and hollow sounding delaminations. Other signs of deterioration include wear, exposed aggregates, discoloration and settlement.


What to Do

Ensuring that the concrete structures will remain safe and functional for years to come requires maintenance and repair. Contact Vector and let us take a look at the structure and show you why we should be your repair contractor of choice.

Application of Smooth & Repair by trowel Application of Smooth & Repair with a finishing trowel


R2-class, rapid-setting, fibre-reinforced cementitious mortar applied in a single layer from 3 to 40 mm thick, for repairing and smoothing concrete.

  • Good maintenance of workability and rapid hardening.
  • Highly thixotropic for easy application on both vertical and overhead surfaces, with no waste.
  • Packed in waterproof vacuum-packed bags for better storage.


Technical characteristics

  • Very low emission level of volatile organic compounds (VOC) EMICODE EC1 R Plus.
  • Highly versatile, by adding its excellent inherent workability can be extended by a further 15-20 minutes.
  • Excellent adhesion (≥ 1.5 MPa) to both old concrete, if roughened and wetted with water prior to application, and to rebar, , anti-corrosion realkalising cementitious mortar certified.
  • High dimensional stability to reduce the risk of cracking and crazing during both the plastic phase and when hardened.
  • Excellent flow to facilitate spreading with a smooth trowel.
  • Easy to create natural finishes with a sponge float around 30 minutes after applying as is and after around 45-50 minutes if admixed with at +20°C.
  • Thermally compatible with freeze/thaw cycles measured as adhesion.
  • Low water permeability.
  • It meets the minimum requirements of  “Structural and non-structural repairs” for nonstructural R2-class mortars and the requirements of EN 1504-2 coating (C) according to principles MC and IR (“Concrete surface protection systems”).
  • The special 25 kg vacuum-packed polyethylene bags allow the product to be stored outside. Contact with the atmosphere and rain have no effect on the product’s characteristics. Also available in cardboard boxes with four 5 kg bags.

Where to use

  • Non-structural repairs and smoothing over internal and external horizontal and vertical concrete surfaces; suitable for repairing structures exposed to the open air and/or in permanent contact with water.
  • Quick repairs to deteriorated parts in concrete and the corners of beams, pillars, buffer walls, cornices and the front edges of balconies.
  • Quickly smoothing over surface defects in cast concrete such as gravel clusters, spacer holes, construction joints, etc. before painting the surface.
  • Repairing and smoothing over concrete mouldings on civil buildings such as skirt roofs and protruding decorative elements.
