Frequently Asked Questions

Polyurethane foam is spray-applied into one seamless layer that insulates against water and heat together and is protected by a reflective coating, while membrane comes in torch-welded rolls, is primarily waterproofing, and is usually covered by a protection screed or tiles. The choice depends on the roof condition and what goes on top.

For an exposed roof that will not be tiled, foam with a reflective protective coating is practical because it combines thermal and water insulation; if the roof will be covered by screed or tiles, membrane beneath the covering layers is the established choice. We inspect and recommend accordingly.

Thermal roof insulation cuts the heat transferred from the roof into the building, which reflects on cooling load; the effect varies with the building, insulation thickness and usage conditions.

Draining and cleaning the tank, inspecting walls and floor and treating cracks, preparing the surfaces, applying an internal lining suitable for water contact, then testing watertightness before refilling.

Common signs: an unexplained drop in water level, damp or algae around the tank base, visible cracks, or an unusually high water bill.

Usually yes — cracks and weak points are treated and a new internal lining applied; larger interventions are only needed for severe structural damage.

They form a hard seamless surface that withstands forklift traffic, resists oils and chemicals, sheds no dust and cleans easily.

Yes, after preparing the surface through cleaning, grinding, and inspecting for leaks. Proper preparation is the basis of adhesion.

Light weight that spares the structure, precise falls toward drains, protection of the waterproofing layer, and added thermal insulation from its cellular structure — suitable for all building roofs and parking lots.

A screed finished mechanically with a rotating-blade power trowel (the "helicopter"), producing a smooth, level, durable surface ideal for parking decks, warehouses and large areas.

When leaks or damp appear on ceilings after rain, the existing insulation layer cracks or peels, or upper floors get noticeably hotter. Treatment starts with an inspection of the existing insulation.

Yes — we waterproof wet areas before tiling, turning the membrane up the walls, detailing drains, and flood-testing before handover.

Crack injection or patch repair, removal of deteriorated concrete, rebar treatment and protection, section rebuilding with suitable repair mortars, plus general restorations and maintenance.

Visible cracks in concrete elements, spalling or hollow-sounding concrete, rust staining on surfaces, or persistent damp — all call for early inspection before the damage compounds.

Yes — our works are delivered with high efficiency and guarantee; the specifics for each project are set out in the technical offer and contract.

Yes — our services include tile installation for all buildings and roofs alongside insulation and foam concrete, allowing us to hand over the roof complete with all its layers.
