       gap of 3–4 hours between the Ist and IInd coat.

 

Note :  For  Waterproofing of new  buildings, the  said treatment  on the mother slab is  the best,  after  2nd coat,  on wet  condition , laying of the cement screed / mortar  treatment  advised for long standing / durable waterproofing.

 

 

SUGGESTIONS:

 

Surface Preparation:

Surface preparation is of great importance and will affect the degree of adhesion and life of the coatings, before carrying out the treatment, the surface must be absolutely free from dirt, dust, laitance, loose particles, grease etc., In case of Tar/bitumen felt was applied earlier, it should be totally removed, by means of wire brushing and if required acid etching can be done.  Surface is then thoroughly sprinkled with water during the summer period.  Recommended plastering  on the  loose particles removed area. 

 

NECESSITY OF TREATMENT:

Acrylic Polymer Elastomeric Cementitious coating system has its importance in waterproofing of a structure, because the applied coating will forms into a tough, highly elastic, water impermeable, seamless membrane which penetrates deeply into the applied substrate.

 

The coating system in alternative to conventional cement of waterproofing will definitely have an edge, because of ease application, excellent performance and high resistant power to with stand against cyclic weather conditions years together.  Being it is an cementitious coating,   its bonding adhesion and high penetration will taken care of coating against mechanical damages. 

 

AS PER THE SITE CONDITION NECESSARY PRODUCT HAS TO DECIDE.

              intervals during the day time for 2 Days on the treated area. 

 

 

SUGGESTIONS:

 

Surface Preparation:

Surface preparation is of great importance and will affect the degree of adhesion and life of the coatings, before carrying out the treatment, the surface must be absolutely free from dirt, dust, laitance, loose particles, grease etc., Surface is then thoroughly sprinkled with water. 

 

 

NECESSITY OF TREATMENT:

Being the entry point of the water is from the negative side  due to the increased  ground water table or by any other reason and oozing  out through the concrete, in some cases the surrounding outside area of the building below the ground level has been fully covered and we can’t excavate the entire area, hence, we must have to treat  the surface from the  internal portion of the  concrete  that means we should have to do the waterproofing from the negative side of the entry point of the leakages.   Since the  objective of  crystallization technology  will be  to  penetrate deep  into the applied concrete  surface  and  due to catalytic reaction  it develops a  non soluable  crystals formation  with a continuous process  upto 30 cms deep into the applied concrete    which  produces  an impermeable  surface  against penetration of water.       

 

ROOFEX  / ROOFEX 2K  ( ARMSTRONG)

The crystalline coating system of  ROOFEX / ROOFEX 2K (ARMSTRONG) to seals the possible pores and capillary tracks of concrete with self  healing of cracks upto 0.4mm.  Excellent waterproofing treatment  for positive and negative pressures of leakages, seepages and dampness protects concrete and reinforced steel permits concrete to breathe, produces crystalline formation on moistured concrete thus it strengthen the pores concrete into a sound /hard substrate through its gross routes.

In case of Tar/bitumen sealant was applied earlier, it should be totally removed. In case of any covering made on original joint it must be broken out and expose the joint.

 

PREPARATION OF GROOVE:

Disturbed edges of the groove must be treated with Polymer cement putty, in case the width of groove was uneven, make it in standard width of 25mm with Polymer Cement Concrete / mortar of 1:2 :4 ratio admixing with Acrylic Polymer admixture for concrete/mortar -  ROOFCRETE  AR 576 Or ROOFBOND SBR  (ARMSTRONG ) @ 2 Ltrs., per bag of 50 kgs., Cement, to get greater compressive and flexural strength of applied concrete/mortar for groove preparation.

           

Heavy structures ROOFBOND EP epoxy bonding  agent preferable.

 

NECESSITY OF POLYSULPHIDE SEALANT:

For sealing of expansion joint the use of Polysulphide is of very much importance as because, the structural expansion joint takes movement of thermal expansion and contractions cyclically, to withstand against the movements cementitious, bitumen materials are not suitable being all this products are not capable to produce required expansion and contraction movements and subsequently these treatments will fails.

 

Whereas the Polysulphide sealant has a unique advantage of accommodation of cyclic movements of expansion and contraction upto 30% of design width of the joint, being it is in rubberized form it won’t allow the water to penetrate thus arresting the leakage of water through the joints, if not disturbed by means of  mechanical or natural calamities.
