Should You Pour Basement Floor Before Or After Under Roof

A full sized basement under at least a portion of your house means the possibility of additional living space.

Should you pour basement floor before or after under roof.

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. Evenly spread the base gravel under the basement slab keeping it 1 inch lower than the conventional method. Garage and basement floors are notorious for stuck on paint.

Properly preparing the subsurface helps to limit the potential for cracks in the finished concrete slab. The obvious advantage in remodeling an existing basement is that it has outside walls ceiling joists and a rough floor. After the drywall is on taped and painted it s time to install the finish flooring. That s why you want the surface to be as smooth and clean as possible before you begin painting concrete floors.

Having the roof completed before wall girts are in place helps protect concrete pour from weather elements especially rain or heat in summer. Preparation is the most important aspect of pouring a concrete slab. Carpet vinyl tile or hardwood installs on top of the subfloor for a finished look. 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. Place a 1 inch layer of 4 x8 extruded polystyrene foam board over the gravel covering the entire floor area. I always pour garage slab after the frame sheeting and roof is done i do the basement and garage at the same time. If there is only a crawl space it is usually more practical to build an addition above ground than to excavate under the house.

Tape the joints between the boards with builder s tape. 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.
