Concrete sawing
Frequently ordered types of concrete sawing in Bergen and the surrounding area
When diamond concrete sawing in private homes, there are several critical preparations and safety measures that must be taken to avoid damage to the building structure, unforgivable mistakes or health hazards.
We take the following into consideration before starting:
1. Structure and Safety
Load-bearing structures (e.g. foundation) must be identified and assessed because it often requires a building application. Incorrect cuts can weaken the load-bearing capacity of the house.
The concrete must be scanned/searched with equipment to locate hidden pipes, electrical cables and rebar inside.
At openings in load-bearing walls, temporary bracing (stamping) must be installed to absorb loads.
2. Preparation of the work area
Furniture and walls are covered, doors to other rooms are closed, ventilation systems (HVAC) are turned off to prevent spread because concrete sawing creates large amounts of dust.
Handling of the sludge is planned during wet concrete sawing for cooling and dust suppression.
We must have access to water and sufficient electrical capacity (often 3-phase or powerful 1-phase circuit).
3. Safety for people
We always wear safety glasses, hearing protection, a dust mask (respirator) and gloves.
Children and pets in particular must be kept away from the work area.
4. Implementation and Technique
Wet sawing is used in several cases to minimize dust and cool the blade.
The area to be cut is marked precisely with chalk or masking tape.
Concrete is very heavy (up to 2.4 tons per cubic meter), so it is cut into manageable pieces.
5. HSE (Health, Environment and Safety)
We use dust extraction or water because Inhaling concrete dust is harmful to health (silicosis).
We ensure that electrical wires do not come into contact with water. 
Cutting Marble
Using a concrete saw (often with a diamond blade) to cut marble is the preferred method because marble is a hard but brittle natural stone that requires precision and cooling to avoid damage. Although marble is softer than granite, its processing requires specific tools to avoid cracks and nicks. It is recommended to use a diamond blade specifically designed for finer stones and let the speed of the saw do the work.
Here are the reasons why concrete saws (with diamond blades) are used on marble:
- diamond blade for cleaner cuts
- wet cutting reduces damage
- precision
- dust control: Using water cooling on a concrete saw binds the harmful silica dust, making the work environment safer
Concrete sawing of fuse boxes in concrete structures
Concrete sawing at fuse boxes is done to upgrade the electrical system or when installing a new fuse box in concrete or masonry walls. This is a common procedure during home renovations to ensure a proper, safe and tidy installation. It is critical to use the right tools (diamond saw) and dust extraction, as a lot of fine dust is created. You should also be aware of the risk of hitting hidden pipes or rebar in the concrete.
The main reasons why concrete needs to be sawed in connection with fuse boxes are:
- concealed system
- cable entry
- upgrade of intake
- concrete cutting for foundation/attachment
Widening of doorways in concrete structures
Widening of doors involves removing the existing door frame, cutting into the wall, and often moving electrical switches, which requires professional carpentry.
Homeowners often widen doors to:
- accommodate the disabled or elderly who need a wheelchair, walker. Standard doors are often too narrow, and widening removes barriers and increases independence in their own home
- prepare the home for future needs, so that they can live in their home for as long as possible without having to move to a more suitable place
- improved flow and light
- functionality and practical considerations
- aesthetics and value addition
Concrete sawing of openings for a staircase in a basement
Concrete sawing to create an opening for a staircase in a basement is a necessary process when establishing a fixed staircase between floors, instead of a traditional hatch. This work is part of a larger process to ensure approval of the basement as a primary room (living room).
The main reasons for using concrete sawing are:
- establishing a fixed staircase
- safety and division
- clean and precise opening
- handling of reinforcement
- dust-free and efficient process
Making doorways in concrete structures
It is a precise method used in renovation and construction projects to modify concrete structures.
Advantages of concrete sawing:
Precision: Provides clean, accurate cuts that require little rework.
Minimal vibration: Wet sawing with diamond tools reduces the risk of causing damage to the rest of the building structure compared to chiseling.
Dust control: The use of water when sawing (wet sawing) binds dust, which is important for health and safety.
The most common reasons for sawing in concrete walls are:
- door and window openings
- installation of technical facilities
- selective demolition and removal
- repair of concrete damage
- crack control
Making windowways in concrete structures
A concrete saw is used to make or enlarge window openings in concrete structures in basement walls (escape windows). For smaller jobs in softer materials such as Leca blocks, a chisel or simpler tool can be used, but for cast-in-place concrete, a concrete saw is the standard.
When is it relevant?
Escape route: To meet daylight and escape route requirements in basements.
Renovation: When existing windows are to be enlarged to let in more light.
New construction: When windows are to be placed in precast concrete elements.
The most common reasons for sawing in concrete walls are:
- precision and straight edges
- handling reinforced concrete
- minimum damage to the environment
- dust control
- deep cutting capacity
Window expansion in concrete structures
When enlarging a window opening, you intervene in the building structure, which means that technical approval/building application is almost always required. It is important to calculate the load-bearing capacity (header/girder) as the wall above the window must withstand the load from the roof or floor divider.
Here are the main reasons why you choose to expand windows:
- more daylight
- psychological benefits
- increased home value and aesthetics
- improved indoor climate and ventilation
- better view and contact with nature
Horizontal concrete sawing in concrete slabs
Benefits of using a saw (instead of a jackhammer):
Reduced risk of injury: Machine sawing provides controlled cuts and reduces the risk of accidental cracking in the concrete, compared to traditional chiseling.
Efficiency: It is a faster method of cutting concrete slabs for improvements.
In addition to structural interventions, the term “Saga” in a flooring context can refer to parquet or laminate brands such as “Saga Parkett,” which are selected for their quality and color selection
This is especially useful when:
- renovating older homes
- installing new pipes/cables
- removing crooked floors
Asphalt sawing
Sawing prevents damage from spreading further into the existing, solid asphalt. This is often done by using a concrete saw to cut into the concrete, preferably within 24 hours of pouring. Using a diamond saw blade ensures clean cuts without cracking the surrounding material.
Asphalt is primarily sawed to:
- when it expands and contracts
- ensure precise, straight edges when precisely repairing road damage (e.g. potholes)
- replace or install infrastructure
- which provides better durability and a more attractive result than breaking up the asphalt
- improve road grip (texturing)
- remove old asphalt
Cutting openings for new stairwells, elevator shafts
Cutting openings in concrete floors and walls for new stairwells and elevator shafts is a critical operation when renovating or remodeling existing buildings.
The main reasons for cutting such openings are:
- Access and functionality
- Upgrading logistics and traffic
- Precision in concrete structures
- Modern standards
- Universal design and accessibility
- Fire safety and escape
Sawing grooves in sidewalks (especially concrete sidewalks)
Concrete is a material that will almost always crack over time due to temperature fluctuations, humidity, and ground movement.
The main reasons why sidewalks are sawed are:
- preventing heaving
- controlled cracking
- managing movement
- durability
Creating a Wall Alcove
A niche is a recess in a wall. This helps personalize a home with masonry or natural materials.
These openings can serve both a functional and decorative purpose:
- to house appliances
- to enhance them with additional lighting
