Garden Levels & Watering
1. Soil levels should be 1 brick below level of a wood floor or a waterproofing membrane properly installed on the outside wall on the part that is above the floor.
2. Water sprinkles should point away from walls and windows adjacent to a wood floor.
Concrete Moisture Levels
Moisture levels in concrete should be under 6% before laying a solid wood floor. New concrete can be under 6% in as little time as 4 months on the surface but may be damper deeper in the slab, so if your new concrete is less than one year old you should apply an epoxy moisture sealer to the surface of the new concrete.
This helps prevent the residual moisture in the concrete from adversely affecting the new floor laid over it.
