Should You Pour Basement Floor Before Or After Under Roof

Place a 1 inch layer of 4 x8 extruded polystyrene foam board over the gravel covering the entire floor area.

Should you pour basement floor before or after under roof.

You want to create a tight insulation layer. That s why you want the surface to be as smooth and clean as possible before you begin painting concrete floors. 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.

Concrete is porous so you need to erect a concrete slab where drainage is not an issue. Carpet vinyl tile or hardwood installs on top of the subfloor for a finished look. With roofing in place and walls open a concrete slab may be installed if desired. Garage always gets backfilled and pouring concrete at later time will allow backfill to settle this way before your pour the slab you add addition fill or stone temper it and you pour your slab.

A full sized basement under at least a portion of your house means the possibility of additional living space. Preparation is the most important aspect of pouring a concrete slab. Tape the joints between the boards with builder s tape. Subsurface water can cause the ground the flex creating stress cracks in the cement.

I always pour garage slab after the frame sheeting and roof is done i do the basement and garage at the same time. Garage and basement floors are notorious for stuck on paint. The obvious advantage in remodeling an existing basement is that it has outside walls ceiling joists and a rough floor. Properly preparing the subsurface helps to limit the potential for cracks in the finished concrete slab.

If there is only a crawl space it is usually more practical to build an addition above ground than to excavate under the house. Having the roof completed before wall girts are in place helps protect concrete pour from weather elements especially rain or heat in summer.
