wall gap Filler foam 

Wall gap filler foam, filling gap between concrete slab and wall
Why leakage from walls and beam
This problem usually occurs during the monsoon seasons. During the rainfalls, water from the external walls seeps inside through the beam joints. This seepage causes moisture damage to the interior portions of the walls.
This entry of water occurs because there are minute gaps present between the beam and wall joints. The usual reasons for these gaps in new buildings are : inflexible material like thermocol or cement grouting is rigid and cracks with time. It can’t withstand expansion- contraction cycles , building movements.
Such seepages lead to shabby homes with the paints peeling off, deterioration of walls, beams and columns. Thus, it significantly reduces the structural integrity of the building.
Traditional Method : Mortar used to fill gap between Wall & Beam joint.
Traditionally this joint is sealed using regular mortar and chips of bricks. However, this combination is rigid. They are exposed to weather fluctuations which cause expansion/ contraction and subtle building movements. Such joints crack and makes way for rainwater to seep into the walls.
Wall gap filler foam
What is required : A gap filling isolation joint expanding foam spray sealant which has high gap filling capability ( up to 1 inch or more)
can be plastered, painted, sanded like concrete
low cost material
easily applied
long life
mildly flexible to sustain building movements
proven technology used in India and abroad.
ISOLATION JOINT PU FOAM SPRAY SEALANT
1 component PU, packed in 750 ml can. Applied using a gun.
When extruded to fill the gaps/ cracks formed, Supex 100 Gun grade PU foam spray sealant expands to fill the gap effectively and seal the joint. Initially in liquid form, the foam cures upon expansion into a flexible material which can compress and decompress like foam.
The property to expand and contract is a highly desirable one. The joints can now offer a higher coefficient of linear expansion than that is shown by the rigid mortar technique. This, in turn, further reduces the probability of Beam- wall joint to crack. Another desirable property of the foam is that it also provides acoustical, thermal insulation.
Depending upon the requirements of the construction to be made, Supex 100 PU Foam is available in FR and non-FR variants.
Isolation joint PU foam spray sealant - Advantages
100 % seepage-free beam-wall joint till the life of the building
Faster process than applying cement mortar - reduced labour costs
Provides acoustical, thermal and Electrical insulation too
Reliable and long-lasting construction
