Protect your property from water damage with EM Construction’s professional waterproofing services. Serving Brooklyn, New York, and the greater New York–New Jersey metro area, our licensed technicians apply proven materials and advanced techniques to keep water out — for good.
Water infiltration is one of the most destructive forces a building can face. Left unchecked, moisture seeps through walls, foundations, and roofs, leading to structural deterioration, mold growth, and costly repairs. EM Construction delivers comprehensive waterproofing solutions tailored to the unique demands of NYC’s dense urban environment.
What We Offer
Exterior Waterproofing
We apply high-performance elastomeric coatings, crystalline waterproofing compounds, and fluid-applied membranes to exterior masonry, concrete, and block walls. These barriers stop water at the source before it can penetrate your building envelope.
Interior Waterproofing Systems
For basements and below-grade spaces already experiencing water intrusion, we install drainage board systems, sump pits, and interior perimeter drains that manage and redirect water safely away from your structure.
Foundation Crack Injection
Hydraulic cement and polyurethane or epoxy crack injections seal active leaks and hairline fractures in poured concrete and block foundations, restoring structural integrity and preventing further water entry.
Roof & Deck Waterproofing
Flat roofs, terraces, and balconies are prime entry points for water. We install TPO, EPDM, and modified bitumen membranes along with liquid-applied deck coatings to create a seamless, durable waterproof layer.
Parapet & Coping Waterproofing
Parapets and coping stones are frequent leak points on commercial and residential buildings. We seal joints, apply flashing, and re-point deteriorated mortar to eliminate vulnerabilities at these critical junctions.
Window & Door Perimeter Sealing
Improper sealing around window frames and door jambs allows wind-driven rain to penetrate walls. Our team installs backer rod and premium elastomeric sealants to create an airtight, watertight perimeter.
Why Waterproofing Cannot Wait
Moisture damage compounds over time. What begins as a minor seepage issue can escalate into cracked foundations, rotted structural members, hazardous mold colonies, and interior finish damage — all of which are far more expensive to remediate than a timely waterproofing treatment.
Our Process
1. Inspection & Assessment — We conduct a thorough evaluation of your property to identify all moisture entry points and their root causes.
2. Surface Preparation — Existing coatings, loose mortar, and contaminants are removed to ensure proper adhesion.
3. Material Application — Industry-grade waterproofing products are applied according to manufacturer specifications and local building codes.
4. Quality Control — Every job is inspected before we leave to confirm complete coverage and seal integrity.
5. Clean-Up & Walkthrough — We restore your site to its original condition and walk you through the completed work.
Materials We Use
We work with leading waterproofing brands including Dryvit, Laticrete, BASF MasterSeal, Tremco, and Henry, selecting the right system for each substrate and exposure condition.
