CONTROL CAVITY™

BASEMENT DRAINAGE MAT

CC 4800, CC 4810

KEEP BASEMENTS DRY WITH MTI

Transform damp basements into comfortable, dry living spaces with MTI’s Control Cavity system. Designed to maintain separation between masonry walls and moisture-sensitive interior finishes, this drainage mat channels water to the drain field, ensuring effective moisture management.

THE MTI ADVANTAGE

  • Temperature and Moisture Resistance: Reduces moisture transfer for a durable solution.
  • Foolproof Installation: Simple process for professional results.
  • Easily Customized: Trimmable with a standard utility knife.
  • Sustainable Design: Made from 100% recycled materials.
  • Versatile Application: Suitable for both new construction and retrofit projects.

APPLICATIONS

  • Interior Below Grade: Perfect for use in basement spaces to manage moisture effectively.

CONTROL CAVITY™ INSTALLATION

  1. Align Panels: Install panels with the channel pattern running vertically and the fabric facing the interior.
  2. Overlap Edges: Ensure all edges and ends overlap by at least 1 inch.
  3. Shingle Fashion: Overlap horizontal edges so the upper sheet back-laps the lower sheet.
  4. Secure Panels: Mechanically fasten the panels with concrete nails or power fasteners every 2 feet on center.
  5. Cover Entire Surface: Repeat the process from top to bottom for complete wall coverage.

SPECIAL INSTRUCTIONS

  • Vent sump baskets, drain tile, and drain field systems, or seal off Floor Edging with caulk.
  • Control Cavity must be covered with appropriate insulation and finished materials.
  • For in-floor heating systems, ensure a vented drain field is installed to manage slab pressure.

CAUTION

  • Combustible: Protect from open flames and high heat sources. Follow all local building codes and regulations.
