Interior Basement Waterproofing in Worcester, MA

Dry Basements for Worcester Homes and Rentals

One drain system at the footing protects every unit and every tenant above it

Interior basement waterproofing stops groundwater at the footing of a Worcester home before it spreads across the floor. We run a perforated drain around the inside perimeter, under the edge of the slab, and bring it to a sealed sump pit. The pump sends the water out through a discharge line that ends well away from the foundation. Owner Diego Tameirao has 25+ years of experience with foundations like these and personally supervises every job. All Pro is rated 5.0 stars on Google.

Three-Deckers

Three Units Sharing One Wet Basement

A leak in a three-decker basement affects every floor

Storage for Every Tenant

Basement storage is often split between units. One wet spring can ruin boxes, bikes and furniture that belong to three households.

Three Sets of Mechanicals

Separate water heaters, boilers or meters for each unit usually share one slab. Water on the floor puts all of them at risk at once.

Shared Laundry on the Slab

Washers and dryers for the building tend to live downstairs. Standing water there means service calls, complaints and lost use.

Worcester Was Built on Three-Deckers

Old frames on stone and brick footings, and a river that runs under downtown

More than 6,000 three-deckers went up in Worcester to house factory workers, and in the 1890s they made up over half of all construction in the city. About 4,000 remain. Most sit on stone or brick foundations, later concrete, and the median three-decker here dates to 1900, with 98% of three-family homes built before 1920.

Worcester calls itself the City of Seven Hills, and water moves downhill through all of them. The Blackstone River forms downtown where the Middle River meets Mill Brook and runs underground through the center. Parts of the city still have combined sewers that carry sewage and rainwater in the same pipes, and in heavy rain they overflow into the Blackstone.

How Hills Change the Water Around a House

Where your home sits on the slope says a lot about where its water comes from

Uphill Water Heads Your Way

Rain that falls on higher ground doesn't stay there. It moves downhill through the soil and collects against foundations on the slope below, long after the storm has passed.

Low Lots Sit Near the Water

Homes at the bottom of a hill or near a brook sit closer to the water table. In spring, groundwater can rise right up to the footing and push in along the cove joint for weeks.

Ledge Sends Water Sideways

Where bedrock sits close to the surface, water can't soak down. It travels along the top of the ledge instead, and a basement dug into that layer ends up catching all of it.
