2. Concrete sealer - Wikipedia

   en.wikipedia.org/wiki/Concrete_sealer

   Concrete sealers are applied to concrete to protect it from surface damage, corrosion, and staining. They either block the pores in the concrete to reduce absorption of water and salts or form an impermeable layer which prevents such materials from passing.

3. Waterstop - Wikipedia

   en.wikipedia.org/wiki/Waterstop

   A subcategory of metal waterstops is coated with polymeric and/or hydrophilic materials in order to provide a higher bond to the concrete and form a secondary barrier against waterseapage. These waterstops come in 25 m coils or in 2.0 - 2.5 m sections.

4. Tetrapod (structure) - Wikipedia

   en.wikipedia.org/wiki/Tetrapod_(structure)

   A tetrapod is a form of wave-dissipating concrete block used to prevent erosion caused by weather and longshore drift, primarily to enforce coastal structures such as seawalls and breakwaters. Tetrapods are made of concrete , and use a tetrahedral shape to dissipate the force of incoming waves by allowing water to flow around rather than ...

5. Wave-dissipating concrete block - Wikipedia

   en.wikipedia.org/.../Wave-dissipating_concrete_block

   Tetrapods used to protect a seawall Large interlocked Xblocs (8.0 m 3 or 280 cu ft) in a trial placement. A wave-dissipating concrete block is a naturally or manually interlocking concrete structure designed and employed to minimize the effects of wave action upon shores and shoreline structures, such as quays and jetties.

6. Sealant - Wikipedia

   en.wikipedia.org/wiki/Sealant

   Sealant is a substance used to block the passage of fluids through openings in materials, [1] a type of mechanical seal. In building construction sealant is sometimes synonymous with caulk (especially if acrylic latex or polyurethane based) [ 2 ] and also serve the purposes of blocking dust, sound and heat transmission.

7. Water tank - Wikipedia

   en.wikipedia.org/wiki/Water_tank

   An elevated water tank, also known as a water tower, will create a pressure at the ground-level outlet of 1 kPa per 10.2 centimetres (4.0 in) or 1 psi per 2.31 feet (0.70 m) of elevation. Thus a tank elevated to 20 metres creates about 200 kPa and a tank elevated to 70 feet creates about 30 psi of discharge pressure, sufficient for most ...

8. Dolos - Wikipedia

   en.wikipedia.org/wiki/Dolos

   A dolos (plural: dolosse [1]: 10 ) is a wave-dissipating concrete block used in great numbers as a form of coastal management. It is a type of tetrapod. Weighing up to 8 tonnes (8.8 short tons), dolosse are used to build revetments for protection against the erosive force of waves from a body of water.

9. Water reducer - Wikipedia

   en.wikipedia.org/wiki/Water_reducer

   Water reducers offer several advantages in their use, listed below: reduces the water content by 5-10%; decreases the concrete porosity; increases the concrete strength by up to 25% (as less water is required for the concrete mixture to remain workable) increases the workability (assuming the amount of free water remains constant)
