Why sealing my pool/tank?
1. I need to seal it internally:
To avoid water leakage which costs and affects the concrete and the reinforcement of the construction. If the pool is in contact with a beneficial living space, leakage also affects the home.
2. I must also seal it externally:
The walls that are in contact with the soil and consequently permanent moisture are treated as a basement wall
The pool / tank seal has peculiarities.
Because, there is continuous hydrostatic pressure
Because when empty, negative pressures are applied
Because it is exposed to external conditions
Because it is exposed to chemical agents (pool water with chemical additives)
Because it must meet hygiene rules (drinking water tank)
TECHNICAL DESCRIPTION INTERNAL POOL/TANK WATERPROOFING
1.Mass-based seals must be used
2.Work joints must be opened and sealed with a flexible mastic or sealed with a hydrophobic profile (eg bentonite).
1.If it is a special PVC sealing membrane usually blue color does not need any other waterproofing.
2. If tiles are the epoxy painting, it is necessary to seal with three layers of flexible cementitious sealing base.
Special care should be taken at the points where the concrete is interrupted by pipes, lights, skimmers The other components, which should be sealed by flexible elastomeric material.
