Polyurethane Liquid waterproofing :
This is a highly recommended method which has been used frequently for treatment of any kind of seepage and leakage. It is a very flexible membrane carefully applied to avoid peeling after some time. Used for roof /terrace, concrete walls and the areas exposed to weathering. Polyurethane Liquid Membrane can offer higher flexibility. Polyurethane is quite sensitive to moisture content present, therefore before application of waterproofing material, one has to be very careful evaluating the moisture content of the concrete slab, otherwise peeling or de-bonding of membranes may happen after some time.
