“Polymer Waterproofing Handbook (Practical Site Guide)” તૈયાર કરી છે. આ handbook contractor, engineer અને applicator માટે ઉપયોગી છે.
📘 Polymer Waterproofing Handbook
(Practical Guide for Construction Sites)
1️⃣ Polymer શું છે?
Polymer એ liquid chemical latex છે જે cement સાથે mix થાય ત્યારે mortar અથવા coating ને વધુ strong, flexible અને waterproof બનાવે છે.
2️⃣ Polymer Waterproofing ના ફાયદા
✔ Adhesion વધારે
✔ Crack resistance
✔ Flexibility
✔ Waterproof barrier
✔ Shrinkage ઓછું
✔ Long life waterproofing
3️⃣ Surface Preparation (સૌથી મહત્વનું)
Before waterproofing:
Dust / oil remove
Loose concrete remove
Cracks V-groove કરો
Surface SSD condition (ભીંજવેલી પણ પાણી ઉભું નહીં)
👉 Waterproofing failures માંથી 60% reason surface preparation છે.
