Repairing Larger Holes and Cracks

cracked badlyRepairing larger cracks or holes in Precast Concrete is quite different to repairing small hairline cracks or holes.

Before you start to repair the holes or cracks, you need to first clean the crack or hole thoroughly to remove any oil, dirt or debris plus the surrounding wall surface.

Pay special attention to the insides of the cracks or holes to make sure they are thoroughly clean to enable the sealant to adhere to the surface.

Enlarge the hole or crack just below the surface with a cold chisel and hammer.

Hold the chisel at an angle inside the crack or hole and chisel down to a depth of about 25 to 30mm. Do this the entire length of the crack and around each hole.

Reverse the angle and repeat the procedure. The whole objective is to create an inverted V shape below the surface, which is also known as undercutting.

The chiselled surface provides a stronger bond with the sealant, and the diverging angle of the crack helps keep the sealant within the crack.

Remove any dust and debris from inside the crack or hole.

cracked wallMix enough ready-mix concrete with water to fill the hole or crack and apply quickly. Use the handle of your trowel to press the mixture into the holes and cracks.

Smooth it over the surface evenly and cure the repaired spot properly before sealing with a silane-based water repelling sealer.

You are also able to chip a hole into a square shape and then insert a new block of concrete into the hole.

Advantages of Precast Concrete Walls

PRE CAST COMPOUND WALL MOULD

When compared to site-cast concrete, precast does have a lot of advantages:

1.    Precast is concrete, manufactured in a controlled casting environment, making it easier to control the mix, placement and curing, then transported to wherever it will be erected.
2.    The quality can be controlled and monitored easier in a controlled casting environment.
3.    Bad weather is not a factor, as you can cast in any weather, and get perfect mixes and methods.
4.    Less labour is required.
5.    Once on site, precast can be installed immediately, as there is no waiting for it to gain strength.
6.    As you have the ability to tightly control the manufacturing process, you get an extremely durable concrete.
7.    Total construction time is less than site-cast concrete.
