Pouring New Slabs In Existing Structures Near Portland, Rochester, Bangor

Leveling & Grading As Necessary

Whether you're planning on finishing the floor after the concrete slab is installed, or you'd simply like to be able to access the space comfortably, a level, even floor is always a fantastic option.

Leveling the floor will prevent puddling in low areas, while also assisting your system in draining excess water to your sump pump system.

Before we install your concrete flooring system, our specialists will remove any loose debris present and level the floor to a flat, even surface.

Install The Delta MS Underslab System

Next, we install a durable Delta MS Underslab Vapor Retarder along the entire floor surface.

The Delta MS Underslab Vapor Retarder System is designed to collect water that may be present on the floor, directing it towards the waterproofing system that will be present along the perimeter of your basement.

As an added benefit, your slab will be protected from water vapor that would otherwise continually rise through the pores of the concrete slab. This is a fast, easy step that will make your basement will be drier and healthier than ever!

Install A Perimeter Drain System

To drain any flooding water out of your basement, we also recommend installing a perimeter drain system (most often our WaterGuard® Drainage System) along the top of the the foundation footing in the interior of your basement. Shown in the image to the left is our FlowGuard System, a second option that's designed to instead be placed in front of the foundation footer.

Any water that enters from the walls or floors will be collected by our perimeter drain. The drainage system is sloped downwards to direct all collected groundwater to your sump pump system, which will also be installed.

Place The Concrete

Once the floor is level and the waterproofing system is in place, our experts will begin to place the concrete for your new slab basement floor.

The concrete floor is typically poured to 3"-4" thickness, ensuring a durable, quality floor. The floor will typically take about a week's time to cure enough for normal use.

Pouring the floor to this thickness also allows us to install the perimeter drain system to be installed on top of the foundation footing, instead of being located in the "mud zone" in front of the footing. This keeps the drain out of the mud and away from potential clogs.

Trowel The Concrete Slab Floor

We take pride in leaving each job looking smooth, professional, and fantastic! Once the concrete floor has been placed, our experts will carefully trowel the floor until it's smooth and clean-looking.

When the work is done, your perimeter drain system will be all but invisible on your floor -- save for a 3/8" flange extending up to collect any water that might leak from the walls.

If you've installed our grated TrenchDrain System to collect water that might flood in from a hatchway entrance, we'll cover it up as we trowel to keep concrete residue from drying on the drain.
