Grounded Expertise. Built for Construction.

Grounded Expertise. Built for Construction.At GEMS, our hydrogeology team is known for being practical, approachable, and laser-focused on construction. We don’t just understand groundwater—we understand how it impacts your schedule, your permits, and your bottom line. We specialize in physical hydrogeology—groundwater flow studies that support land development, dewatering, and water management across the Greater Toronto Area. Whether you’re planning a below-grade parking garage or managing elevated groundwater during excavation, we deliver clear, actionable solutions that keep your project moving. Our services include:

• Construction dewatering system design and management
• Permits to Take Water (PTTW) and Discharge Agreement support
• Site-specific groundwater control strategies
• Regulatory coordination with municipalities and conservation authorities

We work directly with your geotechnical engineers, environmental consultants, and site teams to design groundwater plans that are scientifically sound and construction-ready. From pre-construction planning to excavation and monitoring, we help you avoid delays, reduce risk, and stay compliant.

Our hydrogeologists don’t just sit behind desks—they’ve spent time on job sites, speak the language of construction, and know how to get permits approved without red tape. If you’re looking for a hydrogeology partner who’s responsive, realistic, and ready to work alongside your team, GEMS is the only call you need.

Real-world solutions. No groundwater guesswork.
