How Floating Concrete Slabs Work

Floating slabs are a form of foundation that provides an economical solution compared to traditional slab foundations. Floating slabs do not require excessive excavation but are constructed to "float" on the ground without direct supports like beams, footings, or thickened edges. 

The ECONO-SLAB™ floating slab features a pre-engineered 2-way reinforced perimeter. This distributes loads in more directions, allowing for better stability throughout the slab. 

Learn the various steps to build a floating slab below. 

Construction of Floating Concrete Slab Foundations

Before starting the project, a complete set of site-specific P. Eng stamped drawings are necessary. Foundations should be designed to meet local, municipal, and national building codes. The drawings provide a graphic representation of the final construction to help contractors provide accurate cost estimates and execute builds efficiently.

Concrete slab foundations like ECONO-SLAB™ are designed by professional engineers who assess project needs before developing the best fit solution. ECONO-SLAB™ provides clients with custom-designed foundations and certified drawings.

Preparing Your Site for A Floating Slab Installation

The initial stages of construction require inspection and clearing of the land. This includes removing trees and the upper layer of soil to prepare for digging and filling with concrete.

Skip the Trench Excavation - Ideal for DIYers

The ECONO-SLAB™ design allows for much faster site preparation. Simply remove organic matter down to the hard pan and then compact a minimum of 8" of free-draining gravel to level the surface. And be ready to install the system!

Even when compared to a thickened edge slab, site preparation is simpler, making the ECONO-SLAB™ highly appealing to DIY customers for their projects.

Excavating for Floating Concrete Slabs

Standard projects require trenches for frost walls running 4’-6’. Depending on the building, footing may also be required.

The ECONO-SLAB™ floating concrete slab design, however:

  • Eliminates trenching and excavation required for frost walls and footings, since floating slabs do not require additional forms that need stripping
  • Allows installation of the form days or weeks ahead of schedule compared to standard methods
  • Saves significant amounts of concrete and excavation work, and consequently time and money, since frost walls and footings aren't necessary

Reinforcement for a Strong Floating Slab Foundation

Pre-engineered metal forms and pre-cut bar packages from ECONO-SLAB™ are specifically designed for each project and structure.

A good foundation must be strong enough to withstand all types of loads the building and climate will exert on it.

Easy-to-Follow Installation

Precise Anchor Bolt Location Templates for Floating Slabs

The ECONO-SLAB™ eliminates one of the biggest issues with your anchor bolt placement! Location templates guarantee anchors are set in the exact position required. This allows for perfect placement of the anchors, eliminating a common challenge in foundation placement. Erecting your structure without delays is crucial in a four-season climate.

Multi-Level Reinforced High-Strength Thread Bar

Once the metal form is in place, the ECONO-SLAB™ is formed over the ground. As the concrete is poured in the ECONO-SLAB™ form, the loads are distributed in multiple directions, allowing for better stability. The special rebar helps the concrete support the weight of the structure while also retaining its integrity.

ECONO-SLAB™ floating slab foundation kits ship complete and ready to install with galvalume forms, threaded rebar, fasteners, bolts, an installation manual, and stamped engineered drawings. As a result, less labour to install the system needed, resulting in considerable savings.

See for yourself in our easy-to-follow installation manual.

Pouring the Floating Concrete Slab

With the ECONO-SLAB™ form in place, contact a concrete batch plant to have the required amount of concrete delivered to your location. There is no waiting for contractors to form a project. This is a DIYer's dream!

Using ECONO-SLAB™'s specified concrete mix also eliminates the need for control joints, making the job far easier. Cuts in conventional slabs weaken the foundation before it even gets put to use. A cleanable surface is a must for many businesses today, and cuts in the concrete don't lend themselves to a sanitary environment.

Key Benefits of Floating Slab Foundations

The ECONO-SLAB™ foundation system provides pre-engineered technology and structural superiority for every project. The advantages of ECONO-SLAB™ floating foundations include:

  • Far greater strength than old-fashioned, conventional foundation designs
  • A complete set of site-specific P.Eng stamped drawings in each project, from large industrial projects to 20' x 30' wooden shops in the back yard
  • Environmentally friendly building product with virtually no site waste and no form stripping required once poured
  • Design expertise from professional engineers who assess project needs before developing the best fit solution
  • Custom-designed foundation and certified drawings
  • Significant cost and time savings compared to other foundation installations

ECONO-SLAB™ concrete slab foundations improve the strength of the foundation and simplify the process to get your project complete within your timeline.
