Basement Waterproofing. Stop Water Before It Starts.

Chicago's freeze-thaw cycles and clay soil push water against foundations year-round. Matylac Development installs interior and exterior waterproofing systems, sump pumps, and French drains to keep basements dry across residential and commercial properties.

Scope of Work

Full-Spectrum Waterproofing Solutions

water_drop

Interior Waterproofing

Interior drainage channels and vapor barriers installed along the perimeter to capture and redirect infiltrating water.

foundation

Exterior Waterproofing

Excavation and application of waterproof membrane directly to the foundation wall: the most permanent barrier against soil moisture.

pump

Sump Pump Systems

Primary and battery-backup sump pump installation with proper discharge routing to keep basements dry during heavy rain events.

linear_scale

French Drain Installation

Perforated pipe and gravel systems installed to intercept groundwater before it reaches the foundation wall.

How We Work

Our Waterproofing Process

01

Inspection & Assessment

Identify water entry points, foundation condition, and drainage patterns before specifying any system.

02

System Design

Specify the correct combination of interior, exterior, and mechanical systems for the site's specific conditions.

03

Installation

Professional installation of drainage channels, membrane systems, sump pumps, and discharge lines as specified.

04

Final Testing & Walkthrough

System performance verification and client walkthrough before project close. We confirm all discharge routes and backup systems are operational.

Built for Chicago's Climate

Designed for Freeze-Thaw Conditions

Chicago's clay-heavy soil expands and contracts dramatically through freeze-thaw cycles, creating persistent hydrostatic pressure against foundation walls. We design waterproofing systems specifically for these conditions, not generic solutions imported from drier climates.

FAQ

Common Questions

Waterproofing decisions involve real tradeoffs. Here's what property owners ask most.

What is the best waterproofing method for Chicago's climate? expand_more
Chicago's freeze-thaw cycles and expansive clay soil create hydrostatic pressure that demands durable solutions. For most Chicago basements, a combination of interior drainage channels, a sump pump with battery backup, and waterproof membrane application is the most durable approach. We assess each property individually. Exterior excavation may also be required for severe foundation cracking.
What does basement waterproofing typically cost? expand_more
Cost varies significantly based on basement size, water intrusion severity, and the system required. Interior drainage systems are generally less expensive than full exterior excavation and membrane installation. We provide a detailed written estimate after the initial assessment. There is no charge for the inspection.
How long does basement waterproofing take to complete? expand_more
Interior drainage and sump pump installation typically takes 1 to 3 days depending on basement perimeter and access conditions. Exterior waterproofing with excavation requires more time and is weather-dependent. We provide a project schedule at the pre-construction meeting.
Do I need a permit for basement waterproofing in Chicago? expand_more
Interior drainage and sump pump work generally does not require a permit. Exterior excavation and foundation work may require one depending on the scope. We review permitting requirements during the assessment and handle any required applications as part of the project.
