Wall Sawing Sydney: Creating Openings Into Concrete

by Maria Williams Online Marketing Specialist

Electrical conduits, piping, ductwork, and other building materials travel through the walls and ceilings of your house and transport everything from water to electricity throughout your space. Adding to these electrical or mechanical systems usually requires cutting a hole or creating an opening in the wall.

While this can be pretty easy to accomplish with drywall, creating concrete openings can be much more difficult. You can engage wall sawing services for the best results. However, if you wish to create concrete openings yourself, you must keep certain things in mind.

Planning

Before you begin, here are some key questions that must be answered:

• How big should the opening be?

• Does the opening pass a load-bearing wall?

• Will water, gas, or electricity pipes be damaged if they break through?

• Has the homeowner/landlord approved this project?

Generally, small openings in the wall for data or power cables are not a problem. It’s the big ones that you should be particularly concerned about. In most cases, core drilling is going to be sufficient. But you should know exactly where to start the drilling. This is because if you pass a steel beam on the way through your concrete wall, damage to it can severely affect the statics of the house.

Preparation and Material

When you have answered all the above-listed questions about creating openings with concrete, you can get down to work. Creating concrete wall openings is not particularly difficult, but it can undoubtedly be filthy and noisy. So, keep this in mind before proceeding. You will need the following:

• Spirit level

• Folding rule

• Construction pencil

• Mortise hammer with a flat chisel

• Angle grinder (large) featuring stone saw blade

• Personal protective gear: a hard hat, protective goggles, work gloves, and safety shoes

• Trowel

• Bucket

• Joint iron

• Mortar

• Concrete fall

• Wheelbarrow to pull out the rubble

• Foil for covering

• Props and long squared timber

Prepare the worksite well before you begin; otherwise, the entire project can end in chaos.

Instructions

Now that you have prepared the worksite and gathered all the materials, here are the instructions to create openings with concrete:

1. Empty the room since concrete openings produce enormous amounts of dust and dirt. Then use a spirit level, pencil, and folding rule to draw the exact dimensions of the opening you wish to create.

2. Next, turn off all fuses for the room and turn off the gas and water supply just in case.

3. Use the angle grinder to cut into the wall along the line you drew. If available, first use a small grinder to pre-cut and then use a large angle grinder to retighten.

4. Once the opening is created according to instructions, remove the masonry from inside out via the caulking hammer and an attached flat chisel.

5. If you wish, you can plaster the inner surfaces of the reveals.

This is the most common method of wall sawing services used to create openings with concrete. If you have experience with wall sawing, you should be able to complete the project yourself.

However, if you are not confident, don’t hesitate to engage professional wall sawing Sydney as this is a sensitive project that should be completed accurately and efficiently.
