What Is Steel Surface Preparation?

Some of you may be wondering what steel surface preparation is and why it is important in concrete roof repairs.  It was briefly described in my previous post as cleaning the rusted steel reinforcement bars.  Steel surface preparation is related to cleaning of rusted steel reinforcement bars.


It is important to do clean them thoroughly and all around the circumference of the bars without leaving any rust.  The surface area behind the rusted bars is often overlooked in concrete roof repairs.  This is one of the factors that contributes to concrete cracks and concrete spalling after a few months of completing the concrete roof repair. 


The steel reinforcement bars need to be cleaned so that the next treatment or concrete repair product can bond well with the bars including their whole circumference and the parent concrete behind the bars.  Proper cleaning prevents concrete spalling in future.

Cleaning of steel reinforcement bars manually takes time when the area of concrete roof repair is large.  Another option is to clean these corroded bars using mechanical equipments. 

What Is The Importance Of Roof Leaks Repairs?

Roof leaks repairs are usually done mainly to prevent water leakages on the roof and can enter your house or building.  Roofing materials can be in small pieces or sheets.  When put together to form the roof for your house, gaps between the pieces or sheets can formed over years after being exposed to the changing weather.

Concrete roof casted monolithically on site does not have the problem of gaps on its surface.  Instead, concrete roof has voids when it hardens.  These voids are one of the sources of water leakage inside your house or building.  It also contributes to concrete cracks due to corrosion of steel reinforcement bars.

So, one of the steps in concrete roof repairs is to inspect for water leakage marks on the ceiling or underside of your concrete roof slab.  Water leakage often happens on concrete flat roof.  A concrete flat roof can cause ponding of rain water because there is no gradient on such roof to allow fast removal of water to the drains.

After carrying out any concrete roof repairs, you must conduct roof leaks repairs.  This is to ensure the concrete roof repair will last longer and to prevent rain water leakage.  However there are many types of roof leaks repairs that depend on the type of roof construction. So look out for my new post on this topic.
