Waterproofing Specialists Serving Queens, Nassauand Western Suffolk Counties Since 1955 – The Most Trusted Name in Waterproofing


The wood sill plate is located at the top of the basement foundation wall. This critical junction between the concrete foundation wall and the wood framing should be perched up out of the ground (a minimum of 6″ by code). When this sill plate is below grade, water can flow over it and into the basement.

It is not uncommon for people to try to resolve water problems by “re-grading.” Though it might be comforting to think that paying the landscaper a few hundred dollars to bring some soil in and slope the dirt away from the house, it can be extremely destructive to the wood frame structure. Boccia Inc. can resolve this condition by removing the dirt that is the problem and installing proper drainage.

A Boccia Inc. proprietary Sill Plate Waterproofing System is designed to both seal and drain this location.
