Should You Pour Basement Floor Before Or After Under Roof

I always pour garage slab after the frame sheeting and roof is done i do the basement and garage at the same time.

Should you pour basement floor before or after under roof. During a rainy season a crack in a basement wall can allow an inch or two of water in but before you seek to repair the crack remove all the water from the floor. After the drywall is on taped and painted it s time to install the finish flooring. Properly preparing the subsurface helps to limit the potential for cracks in the finished concrete slab. That s why you want the surface to be as smooth and clean as possible before you begin painting concrete floors.

Preparation is the most important aspect of pouring a concrete slab. Place a 1 inch layer of 4 x8 extruded polystyrene foam board over the gravel covering the entire floor area. If there is only a crawl space it is usually more practical to build an addition above ground than to excavate under the house. Evenly spread the base gravel under the basement slab keeping it 1 inch lower than the conventional method.

Once roof sheathing or roof steel is in place it makes it far easier to plumb building corners. You want to create a tight insulation layer. Tape the joints between the boards with builder s tape. Garage and basement floors are notorious for stuck on paint.

Get rid of the gunk. Having the roof completed before wall girts are in place helps protect concrete pour from weather elements especially rain or heat in summer. With roofing in place and walls open a concrete slab may be installed if desired. Carpet vinyl tile or hardwood installs on top of the subfloor for a finished look.

Concrete is porous so you need to erect a concrete slab where drainage is not an issue. Subsurface water can cause the ground the flex creating stress cracks in the cement.
