The concrete floor in question was under severe sulphate attack. Due to the underlying soil conditions, the ingress of moisture started the reaction. The concrete floor was removed using air hammers and hauled out of the basement.
Abalon recycles. The broken concrete from the basement floor is placed in garbage bins and hauled away to an aggregate recycler. The concrete is then crushed and reused as road base for construction projects.
Exhaust fans are placed in the windows to control dust in the house. The work area is sealed off from the rest of the house.
After removal of floor Abalon exposed areas of the footing that were found to be cracked. Concrete underpinning pads were poured at these locations.
Interior weeping tile was installed around the perimeter of the basement floor, to further control water ingress into the home.
Several large cracks were found in the foundation wall. All cracks were repaired from the outside using Abalon’s proven foundation repair methods.
Abalon installed 28mm wash rock and 10mm reinforcing steel at 18inches on center.
A sump system was installed to remove water from the perimeter weeping tile.
The concrete was placed using a small concrete line pump. The concrete that was used contained sulphate resistant cement.
The HVAC systems were suspended to provide for a smooth installation of the concrete floor.
The concrete floor was placed and finished using laser leveling technology.
Plumbling cleanouts were installed prior to the concrete pour, to provide access to sewer cleanouts as well as the exterior weeping tile system.
The finished flat floor is ready for a new basement development.
Site is excavated and footings are formed on top of the undisturbed soil. Reinforcing steel is used on the entire perimeter. All joints are overlapped.
Weeping tile is used to allow water to travel continuously around the perimeter.
The piece of weeping tile will act as a tunnel for water to get through.
It is important that rebar be used on stepped footings.
Concrete is poured and forms are stripped. Here we can see where weeping tile will be connected from exterior and will travel into the house portion.
Concrete square pads are usually for teleposts. Round pads are used in this project to support garage concrete floor or deck columns.
If the ground is uneven it is important to pour concrete on top and not use any fill to level it.
Foundation walls are formed, poured and stripped. Again we see the drain hole.
We can now see the concrete columns poured on top of the round pads we saw earlier. Typically garage walls are not as deep as the rest of the foundation.
On top of the walls we can see wooden blocks that are inserted to allow for strapping which will be used for siding installation.
Stepped footing at garage and main house junction.
Weeping tile was installed and covered with washed rock. Vertical pieces are used to drain window wells.
Foundation wrap was installed in this project. Wrap is not mandatory; foundation damp proofing can also be used.
As per building code, this foundation is 1.2 meters below grade. The soil backfill will act as insulation to protect footings from frost.
Foundation is backfilled.
We will take you on a tour of a foundation wall replacement that we did in Golden BC during this past winter. Like they say every picture tells a story. This house looks like an average Canadian home.
Abalon was asked to perform a foundation inspection and to provide a written quote. This picture shows that the house is in bad shape and that safety is a real issue.
The project would started in December. Abalon is equipped to perform any type of work in any weather. Abalon drew up plans, obtained engineering and a building permit.
It is important that rebar be used on stepped footings.
Abalon has to deal with a lot of issues including this main water line that was actually leaking because of the pressure that the wall was putting on it.
Abalon has shored the entire house. These walls are deflecting to the point that they are falling in. Abalon recommends that interior finishes be removed only by trained contractors.
The concrete was saw cut and removed in order to have the repairs completed. Abalon is a turnkey contractor. We train crews that will later replace the concrete; no need to involve any other contractors.
Abalon excavated to allow for the removal of the existing bloc wall.
Abalon removed the wall bloc by bloc and recycled all the material.
Abalon removed the walls in 4 phases. This ensures stability and safety. Abalon added a second row of shoring as a safety precaution. Abalon closes the site up every day ensuring your property is safe.
Abalon installed the new PWF walls (Preserved Wood Foundation) the walls were cover until they were ready for backfill.
Abalon is part of the COR wcb safety program. We keep our workers and job sites safe.
Abalon has the PWF walls up and ready for blocking and later to be inspected by the local authorities.
Abalon ensures that all the details are taking care of so that our engineers and inspectors are happy with our work.
Abalon waterproofed the walls, installed foundation wrap flashings, weeping tile washed rock, building paper and stucco mesh and we are now ready for Inspection.
Abalon is proceeding in 4 stages and so are the inspections. Abalon proceeds to backfill the excavation and to insulate the walls to warm up this house.
Abalon has created a nice safe and warm environment.
Abalon will re pour concrete and stucco in the spring to ensure they both last a long time.
Abalon has provided temporary sidewalk blocs until concrete is repoured.
