Polyurethane waterproofing - professional elastic systems for long-term protection
Satecma Bulgaria offers the widest range polyurethane waterproofing in Bulgaria - from liquid elastic membranes and emergency repair compounds to specialized protective varnishes and heat reflective coatings. Our polyurethane systems create a seamless, UV-resistant membrane that withstands extreme temperatures from -40°C to +90°C and retains its elasticity for decades.
What are polyurethane waterproofings?
Polyurethane waterproofings are high-tech polymer-based flexible coatings that are applied in a liquid state and form a continuous flexible membrane. Unlike traditional bituminous coatings, polyurethane systems combine excellent watertightness with the ability for controlled vapor permeability. Satecma Bulgaria offers a full range of solutions - from single compound liquid tyres for quick repairs to aliphatic topicals for long-term UV protection.
Main types of polyurethane waterproofing systems
One-component polyurethane membranes: cure by reaction with moisture in the air, easy to apply with roller or brush. Two-component polyurethane systems: provide higher strength and chemical resistance suitable for professional applications. Aliphatic polyurethane varnishes: transparent or coloured topcoats with excellent UV resistance for finishing coatings. Specialized repair teams: high-viscosity pastes for crack filling and detailed sealing.

Polyurethane waterproofing - elastic protection for roofs, terraces and industrial floors
Satecma Bulgaria delivers a wide range polyurethane waterproofing - from "liquid tyres" for emergency leak stopping to transparent protective varnishes for long-term operation. Our systems create a seamless, UV-resistant membrane that withstands -40°C to +90°C and remains resilient for decades.
How do polyurethane membranes work?
Polyurethane coatings work on the principle of polymerisation by reaction with moisture in the air (moisture-cooled systems) or by mixing two components (catalysed systems). The resulting membrane is both waterproof and controlled vapour permeable, resistant to standing water, acids, alkalis and moderate mechanical traffic. Due to the aliphatic structure of the high quality products, the coatings do not yellow or crack under UV radiation even after years of use.
Liquid rubber for wet surfaces TECMA IMPERAL H2O
IMPERAL H2O is applied even on damp substrates and stops leaks instantly. Ideal for emergency repairs, local maintenance of Gutters, chimneys и fuguesas well as for complete waterproofing of roofs and balconies.
Polyurethane waterproofing with aluminium effect TECMA IMPERAL P-91
IMPERAL P-91 reflects up to 80 % of solar energy, cools the roof and extends the life of old bitumen mushrooms without dismantling. One-part formula for easy application with just a roller.
Waterproofing agent for workpieces TECMA IMPERAL P-2008
IMPERAL P-2008 is a high-viscosity "paste" that fills cracks, corners and wall-to-floor joints before the main coating. It works successfully in high humidity and temperatures above 0 °C.
Colourless polyurethane varnish TECMA PAINT BPU
PAINT BPU is an aliphatic toplak that protects the epoxy и polyurethane floors from abrasion, chemicals and UV. Suitable for car parks, warehouses and outdoor terraces.
Finishing paint for polyurethane membranes TECMA PAINT FINAL
PAINT FINAL is a waterborne aliphatic paint that protects flexible coatings from yellowing and allows light traffic for roof maintenance.
Advantages of polyurethane waterproofings over traditional materials
Polyurethane systems offer significant advantages over bitumen and acrylic coatings: Seamlessness: zero risk of capillary leaks at the joints. High elasticity: covers active cracks up to 2mm without loss of tightness. UV and chemical resistance: aliphatic formulas do not harden or crack even under extreme conditions. Easy upgrade: a new coat can be applied directly on top of the old one without prior sanding. Controlled vapour permeability: prevents condensation and blistering. Wide temperature range: retains its properties from -40°C to +90°C.
Detailed applications of polyurethane waterproofings
Polyurethane systems from Satecma Bulgaria are widely used in various sectors: Roof constructions: flat roofs, terraces, balconies, green roofs and exploitable attics. Industrial sites: production halls, warehouses, cold rooms and chemical tanks. Infrastructure projects: car parks, bridges, tunnels and sewers. Specialized applications: swimming pools, ornamental ponds, hazardous substance storage areas. Renovation of old roofs: direct application on bitumen, metal, concrete and wood without dismantling.
Application technology and professional techniques
Proper application of polyurethane waterproofing requires strict adherence to technology: Substrate preparation: cleaning from dirt, removal of weakened particles, drying at humidity above 20%. Priming: application of a specialised primer to improve adhesion to problematic substrates. Detailed sealing: processing of corners, joints and passages with high-viscosity pastes. Basic coverage: application of 1-2 layers of polyurethane with a total consumption rate of 1.5-2 kg/m². Protective coating: aliphatic topcoat for UV protection when needed. Dry step time is 24 hours, full polymerization - 7 days.
Quality control and technical specifications
All polyurethane products from Satecma Bulgaria meet the strict European standards EN 1504 and EN 14891 for waterproofing membranes. The products are CE marked and tested for: Elasticity: elongation at break > 300%. Adhesion: concrete adhesion > 2.0 N/mm². Waterproof: without penetration at a pressure of 15 bar for 72 hours. UV resistance: no degradation after 2000 hours of artificial aging. Temperature stability: elasticity at -40°C and heat resistance up to +90°C.
Tips for choosing the right polyurethane system
When selecting a polyurethane waterproofing, the specific application conditions must be taken into account: Basis type: for wet substrates, moisture-retardant formulations are recommended, for dry substrates, two-component systems. Intensity of use: for pedestrian areas, coatings with high abrasion resistance are selected. Climatic conditions: in areas with intense UV radiation, aliphatic topcoats are required. Aesthetic requirements: coloured systems for decorative applications or transparent varnishes to preserve the natural look. Satecma Bulgaria specialists provide free consultation for optimal choice.

Maintenance and repair of polyurethane coatings
One of the main advantages of polyurethane waterproofings is their easy maintenance: Regular checkups: visual inspection twice a year for timely detection of problems. Cleaning: removing dirt with neutral detergents without the use of aggressive chemicals. Local repairs: spot application of new material on damaged areas without the need for major interventions. Update: recoating every 10-15 years to maintain optimum properties. Preventive protection: periodic application of UV protective varnishes in highly exposed areas.
Environmental aspects and sustainability
Satecma Bulgaria's polyurethane waterproofings have been developed with the environment in mind: Low VOC content: minimum emissions of volatile organic compounds. Durability: service life of up to 25-30 years reduces the frequency of replacements. Energy efficiency: reflective formulas reduce the need for air conditioning. Recyclability: old coatings can be processed as fillers in new products. Health Safety: the hardened coatings are inert and do not emit harmful substances.
Comparison with alternative waterproofing solutions
When comparing polyurethane systems with other waterproofing materials, several key advantages stand out: Against bituminous membranes: higher UV resistance, elasticity and the possibility of applying liquid coatings. Against EPDM membranes: no joints, easier application around complex geometries and lower cost for small areas. Against PVC membranes: better adhesion to the substrate, root resistance and the possibility of local repairs. Against waterproofing plasters: higher elasticity, watertightness and resistance to mechanical impacts.
