How we work

From your call to a complete coat

  1. 1

    Describe what you see

    Call or message us on WhatsApp and tell us about the roof or tank you want waterproofed and what cracks or damp you can see.

  2. 2

    Surface preparation

    Loose coatings and dirt are removed and existing cracks are treated before spraying, because the material needs a clean sound surface to bond fully.

  3. 3

    Spraying the polyurea

    The material is sprayed under high pressure, reacting in the air and hardening directly on the surface to form a continuous coat over corners, edges and joints.

  4. 4

    Checking the finished coat

    Once spraying is done, the coat is checked to confirm it covers the full area and no spot is left exposed at the edges or drainage outlets.

Questions

Questions about Polyurea insulation

Polyurethane foam is a thick layer that expands after spraying to fill voids and insulate against heat while forming a primary water barrier, but it needs a finish coat over it. Polyurea is a thin, hard, flexible coat sprayed to form a self-contained waterproof skin, and it is often used as the finish coat over other materials.

Yes. The material is flexible, seamless and continuous, which makes it suitable for any surface in constant contact with water, such as tank walls and floors and pool basins. Spraying ensures the material reaches the internal corners that are usually the weakest point in any waterproofing.

Polyurea needs a firm clean surface to bond to. Surfaces that are very damp, crumbling or carrying old loose paint need thorough preparation first, or the coat will lift. It is also not suited to surfaces with unrepaired structural cracks, since polyurea waterproofs but does not fix structural faults.

Not usually. Polyurea is generally the outermost finish layer and it tolerates ultraviolet light and light traffic without needing a cover coat. Polyurethane foam, by contrast, degrades in sunlight if left uncovered, which is why polyurea is sometimes used as the protective coat over foam.

Tell us what type of surface you want waterproofed, whether it is a roof, a tank or a pool, and what you notice now such as damp, cracks or peeling from a previous coat. These details help us judge how much preparation is needed before spraying.
