The main purpose of external weeping tile is preventing water from getting into a basement. However, these pipes can become clogged or damaged, which causes excess water to put pressure on internal walls and basement floors. Water build up inside window wells, after heavy rain or snow, can lead to leaks through basement window seams.
Superabsorbent polymer powder. A superabsorbent polymer (SAP) (also called slush powder) is a water-absorbing hydrophilic homopolymers or copolymers [1] that can absorb and retain extremely large amounts of a liquid relative to its own mass.
This super-absorbent polymer (SAP) has the ability to absorb 100 to 1000 times its mass in water. Sodium polyacrylate is an anionic polyelectrolyte [2] with negatively charged carboxylic groups in the main chain. It is a polymer made up of chains of acrylate compounds.
It is composed of a set of polymeric chains, which are linked together chemically to become a water-insoluble matrix that gently attracts and holds water molecules. The immense size and weight of its molecular structure allows each potassium polyacrylate granule to absorb purified water of over 500 times its dry weight.
Hydrated water gel, or water beads. Water crystal gel or water beads or gel beads is any gel which absorbs and contains a large amount of water.Water gel is usually in spherical form and composed of a water-absorbing superabsorbent polymer (SAP, also known as slush powder in dry form) such as a polyacrylamide (frequently sodium polyacrylate).
