Split Slab

Waterproofing designed for commercial structures where concrete is poured in two layers.

What Is Split Slab Waterproofing?

Without proper waterproofing, gaps between the layers allow water to infiltrate, leading to:

  • Leaks into occupied spaces

  • Mold growth and air quality concerns

  • Structural deterioration

  • Costly damage

By installing a high-performance waterproofing membrane between slabs, we create a barrier that keeps water out and your property safe.


How the Process Works

  1. Schedule a Consultation – Our commercial team inspects your structure and reviews your needs.

  2. Custom Design – We create a waterproofing plan specific to your split slab system.

  3. Professional Installation – Our certified technicians install the waterproofing membrane with precision and care.

  4. Long-Term Protection – Enjoy the confidence of a dry, structurally sound building.
