Wehad Al-Benyan is a Saudi company specialized in waterproofing and thermal insulation. Our crews deliver every project under direct engineering supervision, using materials chosen for the region’s hot coastal climate, with a written warranty of up to 10 years.
Jazan is a coastal city on the Red Sea where intense sun, high humidity and seasonal rains meet. These four factors cause most building problems in the region — and each one has the right insulation solution.
An exposed roof absorbs the sun’s heat all day and stores it in the concrete, then passes it to the upper floors even after sunset. The result: hot rooms, AC units that never stop, and high electricity bills.
Air loaded with moisture and salts seeps into the pores of the concrete, reaches the reinforcing steel and starts the rust that weakens the building from within — showing up as cracks and peeling paint.
Heavy rain exposes any weakness in a roof within hours: ponding water, leaks at corners, expansion joints and pipe outlets, then stains on ceilings and damage to furniture and finishes.
Near the coast, groundwater rises close to the foundations, pressing on buried walls and wicking moisture up the walls by capillary action if they are not insulated.
This is a section of a building roof under rain. Switch between the two modes and watch where the water goes: with insulation it runs off the surface; without it, the concrete soaks it up and it reaches the room below.
Wehad Al-Benyan was founded out of a passion for quality and the belief that solid buildings start with precise, reliable insulation.
We provide advanced waterproofing and thermal insulation solutions that protect buildings from environmental challenges and give them long-lasting durability. We work to the highest industry standards, choose the right materials for each project, and apply modern systems with trained crews.
To us, insulation is not just a technical service — it is a commitment to the building’s safety and the quality of life inside it.

Click any system to read its full explanation: what it’s made of, how we install it step by step, where it’s used, and the projects where we’ve applied it.
Every photo here is from a site we executed ourselves in Jazan. Click any project to see all its photos and details of the system used.
We follow the same six stages on every project, whatever its size. We never move to a stage before confirming the one before it, and we never hand over a roof before a water flood test.
Book an Inspection Visit →Our engineer visits the site, identifies leak sources, the condition of the concrete, slopes and weak points, and photographs everything before work starts.
We propose the right system, its materials and thicknesses, and send a clear, detailed quotation with no hidden items.
Cleaning the surface and removing loose material, treating cracks and expansion joints, and adjusting slopes for drainage.
Installing the layers in order at the specified thicknesses, reinforcing corners and drains, and measuring thickness at several points.
We flood the roof with water and leave it for sufficient time, then check the ceilings below to make sure there is no leak.
You receive the project with a written warranty certificate of up to 10 years and a direct number for after-sales service.
Real reviews written by our clients after receiving their projects.
