Get an AssessmentCommon questions about waterproofing consultants.
a.What does a waterproofing consultant do?
+
A waterproofing consultant independently designs, specifies, and supervises waterproofing systems for buildings — covering terraces, basements, bathrooms, retaining walls, and building envelopes. Unlike contractors, consultants are product-neutral and represent the client's interest, ensuring the right system is selected and correctly installed.
b.Why hire a waterproofing consultant instead of a contractor?
+
Waterproofing contractors sell and apply specific products, while a waterproofing consultant like SIWIN is independent — we design the system, recommend the right specification according to the requirement, evaluate vendors, and supervise execution on your behalf. This eliminates conflicts of interest and ensures you get the best solution for your structure, not the easiest one to sell.
c.Which cities does SIWIN Consultants serve?
+
SIWIN Consultants operates pan-India with an office in Bangalore. We serve projects across Bangalore, Mumbai, Delhi NCR, Chennai, Pune, Hyderabad, Kochi, Coimbatore, Ahmedabad, and other major cities across India.
d.What types of waterproofing problems does SIWIN handle?
+
SIWIN handles all building waterproofing challenges — terrace and roof waterproofing, basement and below-grade waterproofing, bathroom and wet area waterproofing, retaining wall waterproofing, water tank lining, building façade and envelope leakage, expansion joint waterproofing, and post-construction leakage diagnosis and repair.
e.How many projects has SIWIN Consultants completed?
+
SIWIN Consultants has successfully delivered 122+ landmark projects across India, working with clients such as Godrej, Prestige, Infosys, Indian Railways, Kotak, Boeing, Wells Fargo, Mahindra, and many more.
