Waterproofing Solutions for Buildings in Somerville, MA

Waterproofing solutions in Somerville, MA include advanced systems for below-grade foundation protection, parking structure waterproofing, parapet wall sealing, and roof membrane integration to prevent moisture intrusion and structural damage.

What Are Below-Grade Waterproofing Systems?

Below-grade waterproofing protects foundation walls and basement spaces using membrane barriers, drainage boards, and sealants that block groundwater from entering your building's lower levels.

These systems are critical in Somerville, where many older multi-family homes and light commercial buildings have basements or below-grade utility rooms. Water intrusion causes mold, foundation cracking, and damage to mechanical systems.

Exterior waterproofing membranes are applied to the outside of foundation walls during construction or excavation. Interior systems use drainage channels and sump pumps to manage water that penetrates the foundation.

How Does Parking Structure Waterproofing Work?

Parking structure waterproofing uses durable membrane systems and protective coatings on concrete decks to prevent water and de-icing salts from corroding rebar and deteriorating the structure.

Traffic-bearing membranes are installed over concrete surfaces, then topped with protective asphalt or concrete wearing layers. This sandwich construction keeps moisture away from structural elements.

Expansion joints, cracks, and penetrations receive special attention with flexible sealants that accommodate thermal movement. Proper drainage design directs water to scuppers and drains, preventing pooling on deck surfaces.

Somerville's growing residential density includes many new mixed-use buildings with underground or podium parking. Effective waterproofing prevents costly repairs and extends the lifespan of these structures.

Which Parapet Wall Issues Lead to Water Damage?

Parapet walls without proper cap flashing, membrane tie-ins, or sealant maintenance allow water to seep into wall cavities, causing brick spalling, interior leaks, and structural deterioration over time.

Cap flashing covers the top of parapet walls and sheds water away from the wall core. Missing or damaged flashing is one of the most common waterproofing failures in urban buildings.

Roof membranes must extend up the parapet wall and be sealed beneath the cap flashing. Gaps or poor adhesion create entry points for wind-driven rain.

Freeze-thaw cycles in Somerville winters expand trapped moisture, cracking masonry and metal flashing. Regular inspection and sealant renewal prevent expensive facade repairs.

Can Roof Membrane Integration Prevent Leaks?

Yes, properly integrating roof membranes with parapet walls, penetrations, and drainage systems creates a continuous waterproof envelope that eliminates common leak pathways and extends roof life.

Penetrations such as vents, pipes, and HVAC equipment require custom flashings that bond to the roof membrane. Poorly sealed penetrations are a leading cause of commercial roof leaks.

Edge details at parapets, copings, and fascia boards must be carefully executed. Membranes are typically turned up vertical surfaces and mechanically fastened or adhered to prevent wind uplift.

Drainage integration ensures water flows to scuppers, gutters, or internal drains without pooling. Tapered insulation systems can be added to improve slope and prevent standing water.
