Frequently asked questions
How far down is the water table on an island like this?
Not far. The ground is engineered fill placed over bay mud at close to sea level, so there is no depth beneath a foundation for water to drain into - it stands where it is until the tide and the season move it. Drainage here has to redirect water sideways rather than downward.
Does it matter that the ground is fill?
It does. Fill over bay mud sits near sea level, so the water table is close to the surface permanently rather than only after rain, and the mud beneath consolidates unevenly over decades. Both mean below-grade space here has less margin than the same construction inland.
The crawlspace is too tight to get into. What now?
It changes the method rather than the need. Victorian-era crawlspaces often have very little clearance, so assessment relies on what can be reached from access points, moisture readings taken at the perimeter, and what conditions inside the house indicate. It is a real constraint worth raising early.
