When it comes to houses settling in the last 2.5 years in regina and surrounding areas, there are no shortage of settled and sloped houses. Which the lack of moisture in the soil settling is homes are very common to see. I often get the question of at what point do you just do telepost adjustments to put the house on a straight slope or when it is bad enough to bite the bullet and underpin (install piles and lift the house level, so house cannot move in the area any more). The underpinning is by for a lot more expensive, so I only recommend it when it is usually over 1.5 inches depending on the length of the wall. If it is a short walk, say 25 ft, 1.5 inches may be something that bothers a person. Every step u take may be ¼inch of slope and you may notice it. But on a house where the wall is sloping on us is say 40 ft it may not be noticeable at all and in that case I would suggest to just do telepost adjustments and put it on a straight slope, so there is not a drastic rise and drop off. So it’s not very noticeable. Then give tips or grading and other reasons I see that contribute to the reason for the sloping that has taken place. Possibly this way to prevent the need for underpinning in the future.
When going with telepost adjustments and if the telepost need to be lowered to match the out side foundation walls, which is 90 percent of the time what needs to happen. We need to Mae sure the walls are floated.(a void at the top or bottom of the partition walls in the basement) so that when the joists are lowered they don’t sit on the partition walls and make a wavy floor and act as supports. If this if done already great if not we will have to take about 4 inches of usually the bottom vertical (upright) studs out and attach a horizontal (left to right) stud and put a spike into the horizontal upper stud and hammer into bottom plate. This will give a void, so the joists and concrete slab may move up or down with out pushing on the upper floor if the teleposts are adjusted frequently as needed. Also securing the partition walls from moving back and forth at the point of float.
If we choose underpinning. We are digging out that area of the house, installing the piles, lifting as plumb as possible, installing a water proof membrane, new weeping tile, then rock, 2/3 free drainage sand and then a 2 ft cap of clay on a proper grade. So you really do get a lot for your money. Also the piece of mind knowing that the area we underpinned will not move on you again.
