Thank you Daniel & the Hadasa team. I definitely recommend Hadasa Contracting & Excavation. Great service
If you're looking for a reliable and skilled contractor in Toronto area , I highly recommend Hadasa Contracting. They truly deliver exceptional work and outstanding customer service.
Last year a contractor took a job for building a retaining wall in my backyard, dug two huge pits and never came back. As the pits were there all winter and they did nothing to secure we had huge landslide causing damage to my and my neighbours' properties. Upon calling that company multiple times and not getting any help from them we decided to termiate the contract with them and hire Hadasa to fix the damage and finish the walls. Hadasa came to our rescue. They fixed all the problems and compleated the wall. Very good people, they know there stuff and go above and beyond to help their clients. Thanks Daniel and team. I will defenitly hire them in the future if I need them.

When my first contractor bailed on the project leaving me with a very short timeframe to get the job finished, Hadasa C & E stepped right up and got it done. In spite of weather issues, they completed my project in time, paying attention to the small details and providing me with a top quality concrete pad. I would definitely recommend them and will use them again for any additional work I need done.

UNDERPINNING

Underpinning is a construction process used to strengthen and stabilize existing foundations, often necessary due to soil movement, structural weaknesses, or the need for deeper foundations. It involves extending the foundation depth or adding support beneath it using methods such as mass concrete underpinning, beam and base underpinning, or screw piles (helical piles).

Underpinning is commonly used for foundation repairs, basement lowering, or reinforcing structures to support additional loads. Proper engineering, careful excavation, and structural reinforcement are essential to ensure safety and long-term stability. Hadasa Contracting can get your underpinning complete in a safe and secure way ensuring longevity and stability.

CONCRETE BENCHING

Concrete benching for foundation support is a method used to reinforce and stabilize existing foundations, often during basement lowering or underpinning projects. This process involves creating a sloped or stepped concrete ledge along the inside perimeter of the foundation to provide additional support while maintaining structural integrity.

Bench footing is a cost-effective alternative to full underpinning, as it avoids deep excavation while still increasing basement height and stability. Properly designed and installed, concrete benching helps distribute weight evenly and ensures long-term durability for the structure.

QUESTIONS WE’RE OFTEN ASKED

Underpinning is a method of strengthening and stabilizing an existing foundation, often necessary due to soil movement, structural settlement, or to create additional basement height.

Signs include cracks in walls or floors, uneven or sloping floors, sticking doors and windows, or visible foundation shifting. A structural engineer can assess if underpinning is required.

Common methods include mass concrete underpinning, pile underpinning, and screw piles (helical piles), each suited to different soil and structural conditions.

The timeline depends on project size, soil conditions, and method used, but most underpinning projects take 2–6 weeks to complete. Some engineers, based on their findings, require that the underpinning be done in sections (typically 3).

Yes, when performed by professionals like Hadasa Contracting, who use proper engineering and safety measures, underpinning strengthens the foundation and enhances structural integrity.
