Importance of the Waterproofing cement

IMPORTANCE OF WATERPROOFING IN CEMENT

INFORMATION

• Dampness is one of the biggest challenges a
  builder deals with.
• There are many ways damp and moisture can creep
  into a house and the builder has to anticipate
  and see that none of this damages the structure,
  the walls and most critically, the electronics.
• But waterproofing has a much more essential
  function in construction, one that will determine
  the very integrity of a structure.

• This is why solution like adding water proofing
  agent for cement during construction become so
  important

IMPORTANCE OF WATER PROOFING

• The importance of water proofing a structure
  should be obvious.
• But the common man rarely ever realizes how
  critical it is or how layered this waterproofing
  must be. Water can filter in from many sources,
  be it rain or overhead tanks.

• In fact the most common leakages come from the
  pipes and plumbing within the house.
• This isnt just a nuisance that spoils your wall
  with damp patches. There are serious consequences
  of water seepage.

• Infiltration of water can damage the walls,
  weaken the structure, pose a threat to the
  electrical and plumbing layout and cause
  irreversible damage.
• If the seepage is coming from outside, by the
  time you notice it inside your home, the damage
  to the exterior is already done.
• For instance, roof insulation that is soaked will
  never quite recover. Eventually the roof will
  start to decay.
• Similarly, water in the walls will start rusting
  the underlying steel supporting structure.
• Moisture will cause expansion of reinforcing bars
  causing in spelling of concrete.
• To safeguard against this, builders use multiple
  measure, such as adding water proofing agent for
  cement.

WHY WE HAVE TO WATER PROOF CEMENT

• When we use the cement as part of concrete,
  waterproofing is critical.
• Concrete is made by mixing water, cement, sand,
  aggregate and water. Its surfaces is rich in
  oxygen, which makes it hydrophilic in nature.
• It means that the surface reacts with the water,
  forming hydrogen molecules. It absorbs the water.
  
• In case of concrete one has to keep in mind that
  hate is one of the main ingredients when making
  concrete from its mixing too curing.
• While it is important in the making of the
  concrete, the finished product does not contain
  any water molecule.
• Any penetration of water can cause irreparable
  damage.
• So, typically, once the concrete is set, it is
  followed by a curing process where the water
  content is evaporated.

• However, the evaporation of water leaves void
  inside the concrete.
• Hence, good concrete mixtures use the minimal
  possible water in building concrete.
• The low water to cement proportion reduces the
  porosity of the concrete. But given the porosity
  of concrete, it is not possible to make it
  completely waterproof.

• As explained above, the capillary action will see
  that water seeps through the pores of the
  concrete. So, how do we solve the problem? By
  adding water proofing agent for cement.

FUNCTION OF WATERPROOFING AGENT

• A waterproof agent has three main function
• Reducing the size, number and continuity of
  capillary pores. This reduces the penetration of
  water.
• Blocking the capillary pores.
• Using hydrophobic materials with the capillary
  pores. This again reduces the absorption of water
  by capillary action.
• What the waterproof agent effectively does is
  create a barrier to the movement of water.
• It gives the cement or concrete water resistance
  from inside instead of relying on externally
  applied solutions like coatings or sealers, which
  are disruptive, expensive and rarely as effective
  as waterproofing the structure.

• While external solutions provide a barrier to
  water (and many of the modern solutions are
  excellent), waterproofing ensures that we have
  created a structure that is strong from within.
• It is also more economical. If we are considering
  only one waterproofing solution, adding a water
  proofing agent for cement is the most effective
  method.
• Using sealants and coatings are usually
  considered as secondary or extra precautionary
  measures.

WATERPROOFING AGENTS

• Water proofing agents for cement are made of
  hydrophobic materials or materials that repel
  water.
• This includes substances like petroleum products,
  oils, crystalline materials and certain chemicals
  that can block or restrict the penetration of
  water.
• Some substances form an extra layer, while some
  can restrict or repel the movement of water.
• These simple agents determine the very integrity
  of our home.
