Introduction

Waterproofing for Tiled and Un-tiled Roofs is an important topic for property owners in Riyadh because waterproofing quality affects building durability, maintenance costs, and daily comfort.

Why this service matters

The goal is to identify the real source of moisture, heat, or leakage and choose a system that matches the surface condition rather than applying a generic coating.

Inspection before application

A proper inspection checks cracks, slopes, pipe penetrations, concrete condition, moisture level, and old layers before selecting the material.

Common materials

  • Flexible cementitious waterproofing for concrete and wet areas.
  • Epoxy systems for selected tanks and durable floors.
  • Bituminous membranes for many roof applications.
  • Polyurethane foam when water and thermal insulation are both needed.

Professional application steps

The process includes cleaning, crack treatment, priming when required, applying the correct thickness, and testing before handover.
