WHAT IS THE MOST ECONOMICAL WAY TO RECTIFY LEAKING CONCRETE ROOF?

The most economical way to fix a leaking concrete roof depends on the damage.

For minor, localized leaks, Polyurethane (PU) Injection Grouting are the most cost-effective methods. PU Injection Grouting is ideal for filling specific, active cracks without treating the whole roof. A technician drills holes along the crack and pumps in liquid polyurethane, which expands inside the concrete to block water.

For widespread deterioration, either Exposed Torch Applied Waterproofing Membrane or exposed Liquid-Applied Membrane (LAM) are generally the most economical and practical solution for rewaterproof old roofs. These exposed system applied directly over the prepared roof slab, reducing labor, time, and material costs.
