Waterproofing of Terrace Roof Garden

In today's times, where cities lack gardens in order to make space for housing , where high rise buildings and space restrictions have taken away the garden from the houses, building a terrace garden with whatever area you have is the best solution to connect with nature. Dura realizes this and provides you solutions to make sure your terrace remains waterproof despite the roof plantation.

PROCEDURE FOR TERRACE ROOF GARDEN WATERPROOFING

  1. SURFACE PREPARATION
    1. Rake the construction joints to remove loose concrete from the joint.
    2. Drill holes and fixing nozzles in construction Joints and patching the joint with cement sand mortar.
    3. Grout the nozzles thus fixed with cement slurry admixed with DURA-EV (Non shrink polymeric grouting compound).
    4. Clean the RCC Substrate of all oil, grease and loosely adhering particles.
    5. Repair the RCC with rich cement-sand mortar and DURAKRIT if there are any crack (more than 1 mm wide), pinholes, etc. as per the literature of DURAKRIT.
    6. Lay mortar gola using DURAKRIT along the horizontal and vertical edges, other projections, etc. as per the specification of "Mortar Gola".
  2. COATING
    1. Wet the RCC substrate by sprinkling water.
    2. Apply 2 coats of DURAGARD (Cement based Polymer/Acrylic modified highly flexible waterproof coating) taking care the subsequent coat is applied after the previous coat is touch dry as per the literature of DURAGARD. The coats must be applied at right angles to each other @ 2 Kg per Sq mt.
    3. Glass fibre mesh should be laid between the two coats to impart extra tensile strength to the cementitious coating.
    4. The second coat should be followed by third coat of DURAGARD after the second coat is touch dry.
  3. PROTECTIVE LAYER
    1. Apply a 20 mm thick protective layer consisting 1:4:: Cement : Sand mortar admixed with Integral Waterproofing compound DURA 1 at 1-1.5 kg per bag of cement where the RCC has the slope for draining off water. Otherwise, make the adequate slope by PCC.
    2. Before filling the earth/soil proper arrangement shall be made for filtration, draining etc.
