With our practice we often here; " The soils are great, no problem with drainage." Without proper testing, there is no way of determining what exactly is going down beneath the ground. In this picture, there is rusting colouration which is a clear indicator of a high water table. Now if a conventional type of gravity system where to be put in place, the system would quickly be in a state of failure comes the seasonal high water. Thus the importance of conducting due diligence and identifying the soil and the horizons along with percolation/permeameter testing to look for the restrictive layer and identifying the hydraulic loading rates of the soil types. This enables us to determine the right system for the soil type or restrictive challenges. For more information check out our website below or contact us at 250-768-0056
