SRD INFRA started in 2014 as channel partner of Spanish multinational Texsa with 3 waterproofing products in its kitty. Today we are proud to be associated with few of the world's best manufacturers of waterproofing products and have more than 15 waterproofing products in our portfolio. SRD Infra evolved as a solution provider to their clients.
APP (Atactic Polypropylene Polymer) bituminous membranes are manufactured by admixing and modifying premium grade bitumen with APP plastomeric compound. These membranes are reinforced with non-woven polyester felt or glass fibre felt which provides high tear strength and dimensional stability to the membrane.
SBS (Styrene Butadine Styrene) bituminous membranes are manufactured by admixing and modifying premium grade bitumen with SBS elastomeric compound. SBS polymer provides excellent low temperature pliability and elasticity to the membrane which makes it an excellent product for colder regions.
SBS (Styrene Butadine Styrene) based self adhesive bituminous membranes are manufactured using SBS modified premium grade bitumen. Self adhesive membranes are non-reinforced with tri-laminated / cross-laminated / non-cross laminated / polypropylene mesh / aluminium foil / film, as top finish and easily removable silcon film on the underside.
Pre-applied membranes are Type A barriers and are positioned before the concrete is poured. These membranes are found on the external face of the structure and are strong and robust, as concrete is poured against them. Pre-applied membranes are developed for horizontal and vertical external blind side, or confined surfaces waterproofing applications.
Liquid-applied membrane (LAM) is a monolithic, fully-bonded, liquid-based coating suitable for many waterproofing and roofing applications. The coating cures to form a elastomeric barrier, which acts as a waterproof membrane and may be applied over different substrates, including asphalt, bitumen, metal and concrete. These coatings can be brush applied or spray applied.
Synthetic membrane is categorized into two parts PVC & TPO membranes.
PVC waterproofing membrane is made up of high quality flexible (plasticized) polyvinylchloride. This material was first introduced in Europe in 1960's, and even today all round the globe, it is considered best for infrastructure projects with high life expectancy.
