Waterproofing the Footings in Needham
WATERPROOFING THE FOOTINGS
All of the footings for the main house are now poured. The next step involved waterproofing the concrete footings.
As Mike explained, we used a waterproofing membrane product from TREMCO—it’s the same stuff we’re going to use on the exterior of the foundation. We sprayed the top of the footing with this liquid membrane to provide a capillary break. This is necessary because the bottom of the footing is exposed to water underneath. The moisture can be wicked up into the concrete—just like if you dipped the corner of a paper towel in water and then watched as the water wicks up into the rest of the towel. Concrete will do the same thing. So, we have the opportunity to stop that from happening by spraying waterproofing liquid membrane on the top of the footings.
Waterproofing aims to combat any moisture making its way up into the foundation walls and the envelope of your home and living space.
INTERIOR DRAINAGE IS IN
This site has A LOT of groundwater which has been an ongoing concern. So, another step we’ve taken to combat potential problems associated with this is ensuring there is appropriate drainage. For example, interior drainage has been laid around the inside perimeter of the basement. We have two sump pits strategically situated to tie into the interior drainage. Any water that ever makes it up to that level will go into the drainage pipe and then be whisked around to the outside and into basins. Sump pumps will be set up using a float; as soon as that float rises, it will trigger the sump pump to kick on, and the water will be pumped out to the street and deposited into the stormwater drainage.
