Monolithic Slab Repair & Waterproofing

monolithic slab

Not all basement slabs are alike. A Monolithic slab is characterized by a foundation where the concrete and reinforcement of the slab floor and footings are connected. Essentially, the slab and footings can be categorized as one single structure. Whereas a floating slab is characterized by a concrete slab floor or slabs that are not connected to the foundation footer beams or walls.

Different slab types require different approaches. If your basement has a monolithic slab, it’s almost always critical that you keep it intact, whereas floating slab floors do fine with concrete breakout.

Warning – Do Not Break Your Monolithic Slab!

The structural integrity of your home should be of the utmost importance to any contractor working near or around your foundation. When your home is built with a monolithic basement slab the floor is a structural element. If you break the floor of a monolithic basement you could significantly impact the long-term performance of your foundation, transforming a water problem into a serious structural nightmare.

If your basement has a monolithic slab make sure you use the right structural repair solution. Olshan uses an effective method to groove the slab, keeping it in one solid piece, leaving the foundation unharmed.
