Waterproofing & Insulation - العزل (aizel)

Water damage is expensive and it always comes back if it is not fixed properly. BaytiFix waterproofs (عزل / aizel) roofs, terraces, bathrooms (حمّام / hammem) and water tanks, and installs thermal and acoustic insulation that keeps your building dry, comfortable and efficient.

We diagnose the real source of the problem, prepare the surface correctly, and apply the right system for the job - then back it with our satisfaction guarantee.

Lebanese roofs and terraces take a beating: summer heat, winter storms and water tanks that overflow. We diagnose the real source of the leak before quoting, because painting over damp is not a repair. Roofs, terraces, bathrooms, planters and water tanks each get the membrane system that actually suits them.

Every waterproofing job ends with a 48-hour flood test before we hand over, and the price you approve on WhatsApp is the price you pay. We serve all of Greater Beirut: Achrafieh, Hamra, Verdun, Jdeideh, Furn El Chebbak, Baabda, Dbayeh, Aley and the surrounding districts.

Waterproofing & Insulation FAQ

How much does roof waterproofing cost in Lebanon?

It depends on the surface, its condition and the membrane system used, so pricing is per square meter after a free inspection. You receive a written fixed price before any work starts, with the system and warranty stated clearly.

How long does waterproofing last?

A properly installed membrane system on a prepared surface typically lasts 10 years or more. We finish every job with a 48-hour flood test before handover so you are not waiting for the first storm to find out.

Can you fix a leak without redoing the whole roof?

Often yes. We trace the actual entry point first; localized repairs are possible when the rest of the membrane is healthy. If the whole system has failed we will tell you honestly instead of selling you a patch.

Do you waterproof planters, bathrooms and water tanks?

Yes. Planter boxes with anti-root membranes and proper drains, bathrooms before tiling, and potable-safe coatings for water tanks are all standard BaytiFix scopes.

Why is my wall damp in winter?

Common causes in Lebanese buildings are failed roof or terrace membranes, cracked external plaster, or leaking embedded pipes. We inspect, identify the real source and quote the fix, not just the repaint.
