Basement lowering (sometimes called basement underpinning) is the process of removing soil below a crawlspace or concrete slab, excavating the area to create a lower support level, and then adding new concrete footers, walls, and floors to extend the depth or reinforcing an unstable foundation.
This worthwhile home improvement is extensive and may damage your house’s foundation if not done correctly. It requires professional expertise in foundation walls, excavation, footings, and concrete floor replacement. Royal Work Corp. will carefully evaluate the foundation and surrounding area to determine job and building code requirements related to excavation depth, plumbing, electrical re-routing, and concrete work.
The process of underpinning or basement lowering is done for several reasons: A homeowner may want to convert a crawl space or unfinished basement floor into a livable space, and the size or basement ceiling might be too small. A newly finished basement would require additional support, and the basement lowering process can give you extra space while underpinning can increase your load capacity.
With the initial evaluation complete and your goals established, you can bring in an engineer or an architect to design the new space. These experts will draw plans that detail moving and extending load-bearing walls required with this project. They will submit stamped drawings to the local municipality to obtain the necessary building permits before any work begins.
After plans are complete and the permits are issued, the engineers must prepare the site for construction. Furnace connections must be re-routed to move all ductwork and equipment out of the way. The next phase requires technicians to install temporary supports or vertical jacks to hold the home or commercial building in place while the underpinning is being done. Wooden boards or steel beams are used to disburse the structure’s weight and are removed once the project is complete.
There are several methods for completing the underpinning process, depending on the project’s purpose. The Traditional Mass method is used for shallow underpinning. In this instance, the soil underneath the foundation isn’t strong enough to support the home, and the weak soil is excavated and replaced with mass concrete.
This procedure provides both strength and a more efficient distribution of weight. The Beam and Base method utilizes the traditional mass base but incorporates concrete beams, and these are constructed underneath the concrete base to spread the load evenly for better support. A third method called Mini-piled underpinning allows the structure to rest on the stable ground 5 to 15 meters below the current footers. Piles are constructed and cased in steel, and the 15 cm to 30 cm piles are driven into pre-drilled holes to rest on more stable ground.
The fourth and more aesthetic purpose of basement underpinning requires removing the existing concrete floor. The soil is excavated in sections filled with concrete, and small gaps are left between the old and new concrete. Non-shrink grout is used to fill the area in each section.
Regardless of the basement underpinning type, once the process is completed, you can fix the old plumbing problems with new plumbing installed. Our experts will now install a waterproofing system to keep the area dry before adding a waterproofing membrane to prevent water infiltration from the outside.
The exposed foundation walls are then backfilled. It’s now time to waterproof the interior of the basement. An internal weeping tile system is placed around the entire perimeter of the room, below floor level. This drainage pipe will capture groundwater and re-route it to a newly installed sump pump that will safely discharge outside. A layer of gravel covers the entire floor area and will provide a secure base for the new concrete floor.
