Accepted with comments as follows;

1. Before fixing the hydroswell water stop, the concrete surface must be clean free from dust, oils and grease.
2. Adhesive or leveling masterflex paste must be applied strictly according to manufacturer specifications and recommendations
3. Once fixed, the hydroswell water stop shall not be exposed prematurely to water or any other liquids that will cause it to swell before casting concrete.
4. Before casting, inspection shall be carried out and any damaged or pre-mature swelled portion of the waterstop shall be removed and replaced.
5. Placement/ casting of concrete around the waterstop must be done carefully to avoid damage to the waterstop.
