Polyethylene Liners

Polyethylene Liners_STC_المتخصص للتجارة والمقاولات٣The popularity of High Density Polyethylene (HDPE) is primarily due to its low initial material cost and excellent chemical resistance. This allows thicker sections to be used compared to other geomembrane materials. A thick, durable, HDPE liner can be placed in exposed applications where the cost of other materials may be prohibitive. HDPE has excellent chemical resistance which is often the driving force behind the selection of HDPE. HDPE is a field assembled lining material that cannot be practically fabricated in the shop. All HDPE projects, regardless of size, must be installed by trained installers. HDPE is a versatile material which is used widely across all applications. One of the main uses of HDPE is for landfill base liners where its chemical resistance is used to good effect. HDPE can also be used in a multitude of secondary containments, pond linings, and water containment projects. HDPE is best used as an exposed lining material, and has the UV resistance required for many years of outstanding service.Polyethylene Liners_STC_المتخصص للتجارة والمقاولات

Polyurethane Spray Foam

Spray foam insulation provides rapid efficient insulation with no mechanical fixings. Excellent adhesion to any surface ensures seamless thermal insulation for even complex and iregular structures. Spray foam provides both structural stabilisation as well as draught proofing. Robust and durable Isothane’s range of spray foam insulation offers high performing long lasting solutions. STC_spray foam roofing_المتخصص للتجارة والمقاولات

Polyurea

STC_المتخصص للتجارة والمقاولاتـ_polyureaPolyurea spray coatings technology is one of the new developments of the last 20 years.
This technology combines fast curing, even at very low temperatures, and water
insensitivity with exceptional mechanical properties, chemical resistance and durability.
The development of new raw materials and improved spray equipment has made it
possible to overcome the initial problems of this technology such as substrate wetting,
intercoat adhesion and surface finish quality.
The latest development programs are focussing on the extension of the application fields
through the introduction of MDI-prepolymers combining low viscosity with low NCOcontent,
resulting in slower reactivity and/or higher flexibility. Alternatively,
prepolymers with higher NCO-content produce coatings with superior hardness.

Thermal Proofing System

img_2472We have the thermal proofing of different companies including ChemaFoam Co., and Modern Building Chemicals Co. This system includes different thicknesses in the form of boards, well known as extruded foam boards and blue and white injections formed foam boards. Such boards are installed directly on the water proofing of roofs of the houses and factories which are protected by polyethylene or cardboard sheets.stc

Waterproofing System

waterproofingWater proofing is one of the most important systems of STC in different methods including the modified cement insulation, emulsified bitumen, oxidized bitumen, Torch Applied Membrane, polyurethane and acrylic. The modified cement proofing system%d8%b5%d9%88%d8%b1%d9%87_20151031_133738was applied by using the products of SIKA Co. in different locations including Cairo Gallery in which we made the proofing of the swimming pools, tanks and fountains.
