    Shoring options for new basement construction

    Sorry, another thought. You say the neighbour is 7 to 8 feet from the property line. What depth are their foundations at? If they have a basement level then the founding level is likely deep enough that you would be able to open cut and not effect the foundation, as long as you can get...

    Shoring options for new basement construction

    My first question is how did you get approval to have your house right at the property line? Usually there is a set-back requirement to avoid this kind of problem. Second thought is that you had better be on very friendly terms with your neighbour. No matter where the shoring ends up being...

    Do trench boxes qualify as "shoring"?

    A trench box is for one purpose only, safety of workers entering a trench. Trench boxes do not provide any lateral support to the excavation, especially as it relates to supporting adjacent structures. There is always a gap between the outside of the box and the excavation, and the excavation...

    foundation requirement for swimming pool

    The pool manufacturers should be able to provide you the details of their system. Typically the base and sloped portions of the pool are plain concrete (with a fine 'smooth coat' finish), and the side walls are sheet metal panels. The panels typically are about 2.5 feet high and 2 to 8 feet...

    foundation requirement for swimming pool

    Are you talking about a vinyl liner pool or a concrete pool? The two are very different animals. Vinyl liner pools typically have wall sections of sheet metal and are very flexible so there is really not a concern for detailed geotechnical consideration. The exception of course would be the...

    Standard Practice- Subsurface Exploration

    Certainly the level of detail and testing in a site geotech investigation can vary as a function of the type of construction (to a point). However, the issue I would be concerned with is a certain level of work being represented beyond its value in this case. Estimating N-values and providing...

    Pavement Replacement

    I agree with the above comments. If only raising the grade a small amount place an asphalt overlay (taking care to properly clean and tack coat first). If raising the grade more than an inch or two then pulverise the existing asphalt to a depth of about 4 to 6 inches in to the existing...

    Biofilter tank foundation on 2:1 slope

    Is the tank at the top of the 2:1 slope? part way down? What is at the bottom of the slope? Slope stability/failure would be the major concern here and greatly dependent on soil conditions and site layout. How high is the slope? Is the toe eroding? More info needed. Dirtygeo

    Slab on grade cast on compacted soil

    The stresses applied to the soil will vary depending on the rigidity of the foundation, but the underlying soil (especially at any real depth below the structure) do not know what is causing the stress, they just appreciate a change to their stress environment and respond, i.e. settle. It seems...
